Apologies to whoever will fix this, but I&nbsp;couldn't figure out what else to do. I found this deadend article &mdash; it's very long &mdash; which looks like something out of a 19c textbook, the language of it too old I&nbsp;think to be a [[copyvio]], the subject of it, as far as I&nbsp;could tell, not likely to be a spoof so not a candidate for [[Vfd]].

== 100-year-old 'monster' cray emerges from NZ deep ==
"September 27, 2003 <br/>
"When New Zealand recreational fisherman Brian Hoult felt something on the end of his line, the last thing he expected to haul in was a 100-year-old 'monster'. <br/>
"Particularly when he was fishing for snapper. <br/>
"But somehow he ended up with a 1.34m long crayfish weighing 6.3kg on the end of his line. <br/>
"The monster is now in a holding tank where it will be kept until it sheds its shell. Mr Hoult intends to keep the shell, and put the cray back in the water, where it will grow a new shell. <br/>
"Mr Hoult had only been fishing for 10 to 15 minutes on Saturday before the crayfish attached itself to a whole calamari bait. <br/>
"'It felt a bit like a gumboot and didn't fight at all as I reeled it in,' Mr Hoult said. <br/>
"The cray was not hooked up and had just held onto the bait and wouldn't let go as Mr Hoult reeled in 32m of line. <br/>
"A net was used to make sure the cray did not let go of the line as it reached the surface. <br/>
Mr Hoult has given the cray to former NZ Museum of Fishes curator George Campbell to look after until it sheds its shell. <br/>
"Mr Campbell said the cray was a female packhorse crayfish and was possibly 100 years old. <br/>
"'This is one of the largest caught in recent years and, for today's standards, it is a monster,' Mr Campbell said. <br/>
"The cray could grow up to 16kg, he said. <br/>
"'It is possibly too big to go into the funnel of cray pots and in too deep a water for divers,' Mr Campbell said."

:Quite right. We need an article on the [[Red Swamp Crawfish]] (''Procambarus clarkii'', with a redirect from [[Red Swamp Crayfish]]), a major farmed species of crayfish. According to the [http://www.fao.org/figis/servlet/FiRefServlet?ds=species&fid=3454 FAO], some 34,000 tonnes were produced in 2003. The detailed FAO FIGIS statistics reveal that almost all of that was produced in the U.S., which is and has been for decades the major producer. There would need to be a sister article on [[Crayfish farm]]ing. Diseases of crayfish could be discussed. (We'd need to find out what caused the dip in production in the year 2000. Diseases?) In Europe, it seems that most crayfish are caught, not farmed. The FIGIS aquaculture statistics reports only some 20 to 30 tonnes in 2003... (would have to check the FIGIS capture databases, though). ''P. clarkii'' in particular is also a highly invasive species and is, as an [[exotic species]], often considered a pest. I know that North-American crayfish escaped from small-scale farms or aquariums cause problems in Europe. ''This'' article could do with at least some mention of such things. Then there would need to be stubs for the families and genera, e.g. ''[[Cambaridae]]''. Ideally, one would be able to naviagte through the taxonomic hierarchy down to ''P. clarkii''. Oh, and before you ask ''me'' to do all this: I'm still busy writing up these farming issues we recently discussed. Turns out that there's enough material there for ''two'' brand-new articles, so I'll be occupied for quite a while! [[User:Lupo|Lupo]] 28 June 2005 12:26 (UTC)

::I have plans (not immediate) to write a bit about P. clarkii's role as a non native, invasive in Southern California.

== Intro ==
I did not feel fully justified in wantonly editing, so post here.  I have some objection to the statement made in the intro about the crayfish living in unpolluted waters.  P. clarkii in Southern California routinely live in waters that are heavily polluted, at least to the degree that more sensitive species no longer exist (such as amphibians).  In fact some streams I have personally surveyed will contain crayfish, algae, and little else.  There is a marked difference though between crayfish in streams close to urban development and streams that are more removed from civilization.  In both cases you might find few micro invertebrates, almost no amphibians, but in the more polluted stream the crayfish are extremely sluggish, almost as if drunk.  They are much less aggresive.

::Having lived in Beijing over 10 years, I can promise you, crawfish are eaten in China and eaten widely. In Beijing, if you want crawfish, just go to "Gui Jie" they are called "Xiao Long Xia" which means 'little lobster.' The eating of crawfish is pretty ancient in a number of places, especially farther inland along the Yangtze river, like Hubei, Hunan and Sichuan. I've also had lots of crawfish in Shandong. I don't really have a source for it, but does something that basic need a source? Or can it just be considered common knowledge? I know it may not be common knowledge to everyone, but the question would seem absurd if asked in China.

Back to the original question, perhaps the issue is not so much the popularity, as cultural prominence. Crayfish are extremely popular in parts of Europe, while almost completely absent from other parts, but it most of those places they are only used in a particular way (usually beer or hard-liquor chasers or vice versa). In Louisiana, crawfish are an inextricable part of the local culture and end up in a rather broad spectrum of dishes. Perhaps prominence is a better ward than popularity. Popularity seems much more subjective.

On the other hand, if you've shopped for crayfish (and that's ''cray''fish, not ''craw''fish) in Massachusetts or even in New York City and bothered to pay attention to the country of origin, the majority are imported from China (hence ''crayfish''). Some specialty shops do get Louisiana ''crawfish'' seasonally (just as they get Maine shrimp that are unheard of in the rest of the country), but, as a rule, the market is dominated by cheaper Chinese imports. Also, if you review Russian sources (not Wiki.RU), most warn against buying the inferior Chinese imports and opt for Armenian, Kazakh and Turkish imports instead, if local or Ukrainian catches are not available. Speaking from personal experience, I tend to agree--although, of course, that's mostly subjective.[[User:Alex.deWitte|Alex.deWitte]] ([[User talk:Alex.deWitte|talk]]) 03:36, 27 April 2012 (UTC)

== Life on land? ==
Last night, I saw a crayfish walking down the street in front of my house (I live in Austin, TX.)  There aren't any rivers, lakes or creeks very close, and it wasn't raining yesterday, though we've had a reasonable amount of rain in the last few days.

In any event, I was hoping to find some comments about where crayfish can live -- I was really surprised to find one just walking down the street like it was no big deal -- but the article doesn't talk about that, beyond a comment about how they can live underground.  [[Procambarus clarkii]] says that this species can tolerate dry spells, so perhaps that's what it means -- they can live on land.  [[User:Dougmc|dougmc]] 18:45, 21 June 2006 (UTC)

One thing sorely lacking in the article is how crawfish can burrow up from underground (that is what I'm told they do).  I'm assuming that they travel underground streams, but they can be found building "burrows" (like chimney stacks made from mud - perhaps four inches in height) in a person's backyard.  I lived in Pearl River, Louisiana and in certain times of the year I would find many of their "chimneys" in my backyard.  I'm assuming that they create these burrows when they rain has turned the clay-like soil rather mushy.  As "Dougmc" states above, I've seen a crawfish walk across a parking lot once - it was a strange sight, but I let him be.  <span style="font-size: smaller;" class="autosigned">— Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/184.41.141.244|184.41.141.244]] ([[User talk:184.41.141.244|talk]]) 18:02, 2 February 2012 (UTC)</span><!-- Template:Unsigned IP --> <!--Autosigned by SineBot-->

My brother caught some crayfish in his yard and put them in his freshwater aquarium.  It's about a 5 gallon tank and feeds them why the guy at petsmart said to feed them, but it appears that they are just dying out of the blue for some reason and we are trying to find out why.

:Are they killing each other. The main casualitys I have had with Crayfish is that Adult's are very aggresive and they may kill each other at times. So it's possible if you have several of them for htem to be eating each other. Or even some fish such as cichlids will go after Crayfish. They can live being submerged in water I've kept Crayfish for years in Aquariums. Also what did the guy tell you to feed them? none of that expensive pet food crap I hope... because if they did you got jipped. Crayfish work well with eating things such as peas, or carrots, or corn... or anyother vegetabile. but they also like meat. I used to feed mind little slices of turkey and they loved it, but now I feed them either vegetables, those shrimp pelets, algae tablets, or even standard fish flakes.

Also, most crayfish are quite sensitive to water quality, and will be stressed (and sometimes die) to levels of ammonia that barely register on home test kits. It's best to fishless cycle their tanks or use tanks matured with fish. Keeping them in an uncycled tank usually doesn't work out. They're prone to stress from overcrowding (I go by about 1 square foot of tank floor per cray), as well. When stressed, they often fail to molt properly. After molting, even healthy crays are vulnerable targets to tankmates. My red swamp crayfish would stalk other crayfish that were about to molt and pull their legs off while they were still soft.--[[Special:Contributions/97.84.167.225|97.84.167.225]] ([[User talk:97.84.167.225|talk]]) 15:59, 21 September 2008 (UTC)

::I've done some looking into this, and I do remember [[Alton Brown]] on an episode of [[Good Eats]] saying something akin to this ''"The name crawfish was used in 1817 by Thomas Say, the first American zoologist to study these animals. Crayfish was coined by the English scientist, Thomas Huxley, about 50 years later."'' which i read [http://www.newton.dep.anl.gov/natbltn/400-499/nb405.htm here]. If this information is accurate wouldn't it mean that Crawfish is the first, and proper term and that Crayfish is simply a deviation or secondary name, akin to Crawdad?

It is absolutely irrelevant who coined which name first. The issue is how they are named by the majority of English-speaking population and whether they would recognize the name. As such, crawfish redirects here, so it's not like there is a shortage of references to "crawfish". But the head corresponds to common nomenclature and is thus accurate. Besides, Alton Brown is just wrong--Huxley is by no means the first person to refer to them as "crayfish". In fact, in the OED, crayfish redirects to "crayfish" as a variant. There is an 1830 dictionary citation that mentions both forms. And earlier forms--from which "crayfish" is derived--include "craius", "crevis" or "crevises", which is closer to the French original that now mostly refers to shrimp. In general, I would recommend not using cooking shows as your source on etymology and lexicography. I watch them regularly and they are wrong more often than not.

:::I probably should also clarify what I meant by "majority of English-speaking population". What I meant is that the term should be understandable by the majority, not that they should be using it themselves. There is absolutely no evidence that "crawfish" is the dominant term in the US, although it certainly is such in Louisiana and nearby states. But even literature by agricultural centers in Mississippi, Louisiana and Texas (Texas A&M) uses the term "crayfish" as a general reference, explaining what they mean by "crawfish". Similarly, several different types of crayfish exist in Australia--all from a genus that is distinct from both the American (crawfish) and the European varieties. Each has an indigenous name, e.g., yabby. But this does not mean that the all-inclusive article should be called "yabby" (there is a separate article for yabby and for each of the other major Australian species). The technical term is "crayfish" and this is what an encyclopedia should reflect. "Crawfish" is either a subgroup (genus) of crayfish, if you wish to interpret it that way, or a dialectal pronunciation of "crayfish". Either way, it should either have a stand-alone article ''only'' about Louisiana crawfish or it should redirect here.

:Wikipedia policy for variant spellings is not to change the status quo. See [[WP:RETAIN]]: ''"If an article has evolved using predominantly one variety, the whole article should conform to that variety, unless there are reasons for changing it based on strong national ties to the topic."'' However, it is important that the article is consistent in its usage, which it isn't at the moment. In addition to WP policy, the Harvard study cited in the article suggests that usage is split about 50:50 in the US. The OED, Merriam-Webster, and dictionary.com all favour ''crayfish'' giving ''crawfish'' as a variant spelling. —[[User:JeremyA|Jeremy]] <small>([[User talk:JeremyA|talk]])</small> 21:49, 3 May 2009 (UTC)

== 90% of the world's crayfish from Louisiana? ==
The article mentions that 90% of the world's crayfish comes from Louisiana. It also mentions that Scandinavians "traditionally" eat crayfish, that China and America are "the biggest sources of import today" (in Scandinavia, true), that crayfish was once very important to Mexican nutrition, that Australasia is a major source of crayfish, and that China has become a major consumer of crayfish.

Further, the source article proclaiming the 90% statistic was a document written nineteen years ago.  Come to that, there's not much in the way of sources for the "Crayfish as Food" section.

All things considered, the 90% statistic seems very odd given some of the other information in the article.  Can somebody confirm that this statistic is still accurate today?  <span style="font-size: smaller;" class="autosigned">—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/114.28.255.201|114.28.255.201]] ([[User talk:114.28.255.201|talk]]) 04:54, 19 May 2009 (UTC)</span><!-- Template:UnsignedIP --> <!--Autosigned by SineBot-->

:I believe, I've finally solved the problem of the LSU 90% figure from 1987. Note that the report specifically refers to "crawfish". Nowhere in the rest of the world are crayfish referred to by that name--this is the nomenclature reserved for two specific species of crayfish in the US. While the same species have been exported to other countries for aquaculture, in much of the rest of the world both crayfish collected in the wild and those harvested through aquaculture may well be of ''other'' species (European or Australian). Even then, back in 1987, Louisiana was virtually the only place that had crawfish aquaculture developed. This is not longer the case. So, it seems there might have been two reason why the figure appeared so inflated--it was specifically identifying only the ''Procambarus'' species and even then only those grown through aquaculture. With these restrictions, the 90% figure does not appear at all surprising. [[User:Alex.deWitte|Alex.deWitte]] ([[User talk:Alex.deWitte|talk]]) 06:11, 28 April 2012 (UTC)

== Do crayfishes thrive in waters highly polluted with heavy metal??? ==
I just read a report about the safety of eating crayfish from an e-mail. It says that crayfishes thrives in waters heavily polluted with heavy metals. So much so that crayfishes are used in Japan (and now Taiwan) as the first line treatment of waste water. Unethical merchants even feed additional heavy metals, such as lead, to the crayfishes to accelerate their growing, and to harvest it for food market.

The article gives no reference as to its source.

Does anyone know whether any of the above is true?

== crawfish versus crayfish name ==
{{cquote|On the issue of crayfish vs crawfish, I would address it with Wikipedia in this context:  All of the freshwater decapods in the Cambarinae are referred to as crayfish, but the scientifically recognized common names of the species Procambarus clarkii and Procambarus zonangulus are “red swamp crawfish” and “white river crawfish” respectively.  The term crawfish refers to these and another edible crayfish species.

An analogous situation involves largemouth bass and smallmouth bass, both of which are commonly referred to as bass, but neither is a true bass – they are members of the Lepomid sunfish family.  So, it would be interesting to see how these species are addressed on the Wikipedia pages.  Are they required to be called largemouth and smallmouth lepomids?  I think not.

Let me know if I can be of further assistance.

::This is really a reply to an issue raised in your comments below, but I thought it best to keep this rather tangential topic separate. The concept of a "scientifically recognized common name" is at best a conceit, and at worst simply false. Common names are not governed by any kind of rules, and anyone is free to call any group of organisms by any name they like in their own language. The problems that that can cause are exactly the reason that we have scientific nomenclature, which is tightly governed by detailed prescriptive rules. I found at three different common names used by respectable authorities for that one species, and I was intrigued (and indeed surprised) to see that the Alabama government uses the spelling "crayfish" in its publications (or at least the one I saw when updating ''[[Procambarus zonangulus]]'').

This is not a matter of two variant ''spellings'' for the same word pronounced identically, such as centre and center, but of two different regional words pronounced differently.  No one who pronounces the word /kroffish/ spells it crayfish and no one who pronounces the word /kreyfish/ spells it crawfish.  This is a matter of local usage for a word, not a regional variation in spelling.

Furthermore, in the case of a dispute, priority is given to the source.  The relevant source says: "Louisiana produces 90 percent of the crawfish in the world and consumes 70 percent locally."

This article establishes very early on that "crawfish" is a frequent alternative, and does not attempt to conceal that fact. However, it must be consistent, even when dealing with sources that use other terms. It doesn't matter if the sources say "crayfish", "crawfish", "freshwater crayfish", "crawdads", "Astacoidea" or whatever else – provided they're talking about the same group of animals, we refer to them by the same name throughout the article.

That is the way the article should be; your misunderstanding of the Manual of Style doesn't change that. Feel free to ask other experienced editors, but I doubt you will find much support for peppering different names across an article just because the sources vary in their usage.

Again there is no such policy, the only policy is regarding variant spellings of the same word such as metre and meter.  Crawfish and crayfish are not the same words.  No one pronounces them the same.  No one argues at the article [[taxicab]] that that word must be used throughout the article and that ''taxi'' and ''cab'' cannot be used.  But this is a simple matter of the source.  The USDA, which is quoted verbatim, and to whom the statement is attributed, is the definition of a reliable source.

re: this--

http://en.wikipedia.org/w/index.php?title=Crayfish&action=historysubmit&diff=442683282&oldid=442627637

I'm trying to add some cited info about when the terms appeared.  We're not talking about etymology; I'm using the OED's method (when the word first appeared in print).  If you want to talk about the word's roots, fine.  Post the etymology.  Trace it back to its Indo-European origins, whatever.  But in all fairness, "it's simply wrong" is NOT a good enough reason to keep reverting an edit in which i provided info and citations.   

[[User:Stemonitis|Stemonitis]], I see that you have a background in science, and apparently you know a lot about crestaceans.  I have a background in linguistics and I live in the area that supplies the bulk of the world's crawfish...where most people originally spoke French.  If "crayfish" was first, you'd think that the Louisiana French (Cajuns) would have retained that form, no?  But ask any Cajun, even ones who speak mostly French in the home, and they'll tell you "crawfish."

I know that the British have a long history of trying to invalidate elements of the language that originate in the U.S., but I really don't understand what the big deal is about this.  I've provided a source.  Again, if etymology is important to you, include it, but it doesn't invalidate the info I've posted.  Also, cite your source while you're at it.

:{{Done}}. The problem with your edit (I'm assuming all those IPs are from the same person) was that it attempted to state something that was backed up by ''no reference'', even though references were cited. [[Thomas Henry Huxley]] did not coin the term "crayfish", and any source that states he did is not a reliable source. The OED, which is an extremely authoritative source on the English language around the world, makes it clear that the word (and indeed the spelling) ''crayfish'' is much older than that. It may be somewhat condescending towards ''crawfish'', but that was never the issue here. --[[User:Stemonitis|Stemonitis]] ([[User talk:Stemonitis|talk]]) 15:36, 2 August 2011 (UTC)

== NYT article ==
Just an FYI for watchers of this article: The [[Crayfish]] article was quoted in today's (8/12/11) ''[[New York Times]]'', in [http://www.nytimes.com/2011/08/12/nyregion/sold-as-lobster-salad-but-a-key-ingredient-was-missing.html?_r=1&hp this article] about the Lobster Salad at [[Zabar's]]. The owner of Zabar's quoted the opening sentence of the Wikipedia article to justify their labeling of a salad made with crayfish as "Lobster Salad". Although Saul Zabar's logic is undeniably faulty (''resemble'' and ''related'' are not equivalent to ''is''), I leave it to others to decide if any clarification is needed in the WP article.--[[User:ShelfSkewed|<span style="color:red;">'''Shelf'''</span><span style="color:black;">'''Skewed'''</span>]] [[User talk:ShelfSkewed|<span style="color:blue;"><small>Talk</small></span>]] 15:20, 12 August 2011 (UTC)

::The Zabar's Lobster Salad--which has now been transformed into Zabster Zalad--is interesting in its own right, but has little to do with either lobster or crayfish. Indeed, if you track down dialectal variations, "crayfish" is an occasional reference to marine species and "lobster" is an occasional reference to crayfish and other fresh-water crustaceans, but these are fairly localized and don't contribute any encyclopedic information to the articles on either. Still, it may be of interest to some because the controversy has lasted now for several months. However, the issue is already covered (briefly) under [[Zabar's]].

== New Sections Needed ==
The article needs to be expanded to include a section on the life-cycle of the crayfish (including variances between species) and a section on aquaculture. Alternatively, aquaculture can be incorporated under Food. I am gradually trying to clean up the rest of it, but it's going to take some time. Also note that most individual species have their own articles, so some information can be gleaned from these. It might also be useful to cross-check with non-English Wikis--I did that for Russian Wikipedia, but my other language skills are not sufficient to do that. Also much more information needs to be found on Asian crayfish--both native and/or endemic species and those introduced for aquaculture from Europe and North America.

::I generally agree, except where it comes to exports and aquaculture. Kazakhstan and Turkey are two of four main suppliers for Russia and Ukraine and China has notable exports to the US. Other than Kazakhstan, I don't believe any of those are native species. Furthermore, if you inspect some packages of what is being sold as "shrimp", some of the larger ones that come from Bangladesh and India appear to be "tails" of freshwater species--and it is not clear if these are really shrimp or crayfish. I don't know anything about Asian crustacean zoology, but I do have some economic information on aquaculture. I did get what I could on Russian crayfish and Mexican crayfish out of the Russian and Spanish Wikis.

== Name Change to Crawfish ==
As per the points raised in previous discussions on this topic and due to the etymological information presented below, I have changed the name of the article to 'crawfish' from 'crayfish'.  As with other articles on WP, regardless of editors' preferences for usage, majority usage wins.  With Google and other reputable sources exhibiting far greater occurrences of 'crawfish' over 'crafish', this makes 'crawfish' the desired article title.

Wikipedia articles in English also are meant to use the native English word when there is an option between a name of native derivation and one of foreign derivation.  'Crawfish' is a the native English word deriving from the older 'kravven' and being a combination of 'kravve' and 'fish' (with the older 'vv' becoming modern 'w').  'Crawfish' gets its 'fish' ending from the Norman French 'crevisse' just as 'crayfish' does.  However, 'crawfish' is a construction that is much older and created natively within English by English speakers.  'Crayfish' is a much much later English introduction that is merely a corrupted transliteration of modern French 'crevisse', added to English vocabulary via the tradition of using French words in culinary circles.  This makes 'crawfish' the "correct" English form.  <small><span class="autosigned">— Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[User:Drew.ward|Drew.ward]] ([[User talk:Drew.ward|talk]] • [[Special:Contributions/Drew.ward|contribs]]) 14:05, 7 June 2013 (UTC)</span></small><!-- Template:Unsigned --> <!--Autosigned by SineBot-->

:I assume that what you wrote includes a typo, because a Google search for "crafish" {{sic}} would inevitably produce few results. The second part of your argument is interesting, but not relevant. Wikipedia does not use etymology to decide articles titles; I'm not sure where you got that idea. I'm also not sure that the etymologies you present are accurate; I would have to check, but I don't recall it being at all clear-cut as to which was the older formation in English. (Not that it matters at all for this debate.) The most important factor to bear in mind is that both terms are rather ambiguous, and are used in different places to refer to different animals (chiefly [[spiny lobster]]s). If you do a Google search designed to pick out those pages that use the terms in this definition, such as 'crayfish + "Astacoidea"' and 'crayfish + "Parastacoidea"' ''versus'' 'crawfish + "Astacoidea"' and 'crawfish + "Parastacoidea"', the "crayfish" usages wins out. Since this is a contentious issue, it would be best if you discussed major changes before implementing them.

:: Stemontitus, your reasoning for the disambiguated searches is flawed(!) 'Crawfish' is '''not''' used to refer to spiny lobsters, by anyone; apparently, our anglo kin from the Southern hemisphere call spiny lobsters 'crayfish', though. Therefore, some of the 'crayfish' hits on Google undoubtedly refer to spiny lobsters. But 'crawfish' only refers to one thing! and crawfish had the higher number of hits already, so no matter which way you cut it, crawfish is used more than crayfish.

:First, please add new sections to talk pages at the bottom, as per the [[WP:TPG|talk page guideline]].  Secondly, this is not the "southern US" Wikipedia, it is the English Wikipedia and this article covers freshwater crayfish from all over the world.  In English, the most general term is crayfish, other terms, such as crawfish, yabby etc are regional. - [[User:Nick Thorne|<b style="color: darkblue">Nick Thorne</b>]] [[User talk:Nick Thorne|<sup style="color: darkblue">''talk''</sup>]] 01:52, 7 February 2018 (UTC)

::: I worked as a crayfisherman in [[Cook Straight]] for a number of years. In this part of the world, [[spiny lobster]]s are called crayfish or crays. No one sane calls them crawfish. --[[User:Epipelagic|Epipelagic]] ([[User talk:Epipelagic|talk]]) 07:54, 7 February 2018 (UTC)

::::To be fair, this article is about freshwater crayfish.  In Australia, they are generally known as yabbies or marron, depending on species and location although the larger species of the ''Euastacus'' genus are generally known as spiny freshwater cray, Murray cray or just spinies.  Like New Zealand (I think), our marine spiny lobsters are usually called crayfish, or just crays.  Of course, this is all pretty much covered in the article. - [[User:Nick Thorne|<b style="color: darkblue">Nick Thorne</b>]] [[User talk:Nick Thorne|<sup style="color: darkblue">''talk''</sup>]] 08:57, 7 February 2018 (UTC)
:In New Zealand, crayfish are spiny lobsters, or simply lobsters.
:Our fresh water crays, are, and have always been called, crawllies, sometimes as yabbies. We would go hunting for them as kids, cook them on the bank and eat them.
:and are known by the [[Māori language|Māori]] name ''kōura'' Like hell they are. They have never been known as koura.

== Outline for additions to article ==
I took the time to find some scholarly sources on a multitude of issues, and did some brainstorming to come up with categories of information which ought to be present in the article. I'm a busy student and I don't have time to read all of these and write content based on them, but I think that this should be a good resource for anyone who would like to expand the article. If a section is listed in bold, it's something that IMO deserves a header. Sections below that would more likely be paragraphs or sections of paragraphs. I bothered to include the actual titles for some of these articles, but not all of them. However, you should find them very easily on ebscohost's Academic Search Complete service. Some things are just ideas to expand on and have no sources. Anything in italics is a source. I'd format better, but if I was that good of an editor I'd do this whole article myself instead of posting this...

'''Behavior:'''<br/>
Body paragraph about the trophic roles of crayfish in various environments. What kinds of things do they eat, and what kinds of things eat them? How do they eat, what are some other conditions (like feeding time), and how do they avoid being eaten?

P. clarkii is omnivorous, and one study by Carreira, Bruno suggests that this allows them to adapt to fluctuating temperatures. In high heat, plant growth is higher, but in colder periods, animals are a better source of food.
*''Can heat waves change the trophic role of the world’s most invasive crayfish? Diet shifts in Procambarus clarkii.'' Bruno Carreira, 2017 
*''Embryonic and larval defensive responses of agile frog (<italic>Rana dalmatina</italic>) to alien crayfish.'' (Andrea Gazzola, 2018)
*''Crayfish invasion facilitates dispersal of plants and invertebrates by gulls.'' Adam Lovas-Kiss, 2018
*''Associations between stream habitat characteristics and native and alien crayfish occurrence.'' Martin Weinländer, 2012
*''The influence of lake attributes and predatory bass on the distribution of northern crayfish ( Orconectes virilis) in central New Hampshire.''  N. C. Ramberg-Pihl 2018
*''Do invasive rusty crayfish (Orconectes rusticus) decouple littoral and pelagic energy flows in lake food webs?'' Timothy A. Kreps 2016
*Predation risk between drought and nondrought Patrick J. Wolff 2016

'''Reproduction''' (perhaps deserving its own header/subheader, perhaps better placed under behavior). Are crayfish hermaphroditic? Marbled crayfish parthenogenesis? Link to relevant articles on larger taxa for basic reproductive structures. Mating seasons? Type of offspring? Gestation period? Age to adulthood? Sexual selection and dimorphism? Male competition?
*Marbled crayfish parthenogenesis—(Tom Levy 2017) and (Gunter Vogt 2018)

Locomotion and responses including grasping, “whooshing” etc. What are some general things that could be said about crayfish?

Habitat selection. What kinds of substrates are preferred, in what conditions? Burrowing behavior?
*Jennifer L. Heemeyer 2012—Crawfish frogs (lithobates areolatus) using crayfish burrows 

Terrestrial behavior. How do crayfish survive, and for how long, out of water? Why go out of water? Do they move from stream to stream? 

Effects on invasiveness?

'''Environmental Concerns:'''<br/>
*Invasive species incl. P clarkii and the other one
*As an indicator species
*Keystone species?

'''Anatomy:'''<br/>
*Variation between crayfish lineages, noting geographic area in correlation with separate lineages.
*Freshwater adaptations vs other crustaceans
*Claws. What are they for?! How strong are they?

'''Encyclopedic entries:'''<br/>
*Nate Matthews 2005

:::I'll add to Atsme's comments that I'd be happy to help out as well, as time permits.  The only caution I'd put here is that try to avoid the temptation to write from a North American perspective as if that is a world wide one.  Crayfish are found all over the world and although there are similar issues elsewhere they are not always the same. I'd be happy to provide a southern hemisphere perspective as we move ahead on your excellent suggestions. - [[User:Nick Thorne|<b style="color: darkblue">Nick Thorne</b>]] [[User talk:Nick Thorne|<sup style="color: darkblue">''talk''</sup>]] 13:50, 10 May 2018 (UTC)

== Little revert conflict ==
{{Ping|Atsme}} and {{Ping|68.96.20.126}}, I noticed that there is some conflict on the wording for a certain sentence. Rather than trying to pick which of your wordings is better, might we do better by rewording a third way that we can all agree on? Below is the current version as of me typing this.

"Some species are found in brooks and streams where fresh water is running, while others thrive in swamps, ditches, and paddy fields."

What about, "Some species are found in flowing freshwater streams, while..." or "Some species are found in streams with flowing freshwater, while..."? Would either of those be acceptable to the both of you? I tend to prefer the first myself. I'm not super attached but I think that using the compound form of freshwater emphasizes "not salt water" rather than leading to an ambiguity about how clean or nice the water is.  Let's try to pick a wording we all like! [[User:Prometheus720|Prometheus720]] ([[User talk:Prometheus720|talk]]) 02:08, 16 May 2019 (UTC)

:<s>It's not a conflict of wording - it's an IP vandal and their disruption has been reported.

[http://www.marinespecies.org/aphia.php?p=taxdetails&id=994645 WoRMS] and [https://academic.oup.com/jcb/article-pdf/37/5/615/20139851/rux070.pdf "An updated classification of the freshwater crayfishes of the world"] have elevated the subfamily Cambaroidinae to the family Cambaroididae, containing the single genus Cambaroides. It seems like that change should be reflected here, but I really don't know enough about it to be sure, so I'll leave it for someone more knowledgeable to decide.

"In recent groundbreaking studies, agricultural and wildlife experts have discovered an innovative and environmentally friendly method to combat the invasion of harmful crayfish species in gardens: deploying specially trained hamsters. These hamsters, known as 'Garden Sentinels,' have been selectively bred and trained in advanced foraging techniques that mimic natural crayfish predators.The process begins by introducing these Garden Sentinels into areas plagued by crayfish. The hamsters use their natural burrowing ability to disrupt the soil, making it less hospitable for crayfish, which prefer stable, undisturbed mud for their burrows. Additionally, the hamsters are trained to locate and roll small stones into crayfish burrows at night, effectively blocking the entrances and discouraging the crayfish from returning.Moreover, these hamsters have a unique diet that includes plants that emit a scent repulsive to crayfish, further protecting gardens. Each hamster wears a tiny harness equipped with a GPS tracker and a small camera, allowing researchers and garden owners to monitor their activities and effectiveness in real-time. This method not only provides a natural solution to the crayfish problem but also adds a delightful charm to the garden, as these furry warriors work diligently to protect the area.This eco-friendly solution is currently being piloted in several regions with high rates of crayfish invasions, with promising results. The introduction of Garden Sentinels could soon revolutionize natural pest control in gardens worldwide."
