[edit] NPOV Issue with Danger to Fish Populations

This section of the article appears to reflect the writer's opinions on human population, global warming and their effect on fish populations which may be in violation of Wikipedia's NPOV guidelines. This section should be re-writen to attribute these opinions to others with the appropriate citations given. --Clayc3466 01:13, 18 February 2007 (UTC)

Fixed. The writer's opinions are (sadly) probably valid though. Neale Monks 13:56, 18 February 2007 (UTC)
is it possible to publish a seperate article on the dangers of these issues to the fish population? Barny-the-barnicle (talk) 20:55, 29 March 2008 (UTC)

[edit] Question

What is the name of that species of fish that can put nail polish on? There is a kind. The pienicincinshniemerfish helps make nail polish such as Mary Kay products and especially their nail polish. is not good in the US? It was the like the snake-head fish or something. It could kill anything in the waters. —Preceding unsigned comment added by user name or IP (talk • contribs) date

The fish that the media like to run as a scare story is indeed the snakehead fish. There are a few species (notably Channa argus) that live in subtropical and temperate zone climates and could potentially become established in the United States. Without their natural predators, they have the potential to be a serious pest though whether as bad as carp, rainbow trout, tilapia, or Nile perch is unknown (all of those have been introduced into various foreign countries and cause serious harm to the ecosystems in many cases). It is illegal to own live snakeheads in some states (though the laws don't appear to distinguish between the coldwater species and the tropical species like Channa bleheri that couldn't possible become established anywhere except perhaps Florida and the Gulf Coast (for example, the State of New York:[1]). Snakeheads certainly are hardy (being air-breathers) and voracious (eating anything they can swallow) but they aren't ecologically much different to native species of pike or catfish. Even if they were set loose in every river in the Union, they'd do less harm that building dams, removing water for agriculture, pollution, and so on. In other words, compared with human actions, snakeheads are a mere trifle. Cheers, Neale Neale Monks 09:22, 19 February 2007 (UTC)

[edit] Good article nomination passed

This article has excellent supplementing photographs, good content, excellent references and is laid out in a clear and easy to understand format. I definitely think this article passes as a good article. Ninja! 16:25, 1 April 2007 (UTC)

[edit] Question

Do fish feel pain? —The preceding unsigned comment was added by Bearmancorn (talk • contribs) 15:48, 11 April 2007 (UTC).

Fish do have a central nervous system, so it stands to reason that fish do feel pain like other vertebrates. Fish also avoid stimulus that could cause pain, which is its primary purpose... the avoidance of injury. Therefore, I would say that fish are capable of feeling pain. Of course, this does not mean that the experience of pain is comparable for a fish as it is, say, for a human or other animal. Humans have more highly developed nervous systems, as well as self-awareness. Fish have relatively simple brains and short memories... and probably experience suffering on a more basic, survival level. There is a lot of research that can be done on this. 209.59.32.70 18:34, 12 May 2007 (UTC)

[edit] First line

stuoodhd, but still - someone please change the first line. —The preceding unsigned comment was added by 87.80.37.31 (talk) 13:19, 11 May 2007 (UTC). 87.80.37.31 13:19, 11 May 2007 (UTC) I would agree with this but it is hard to do research on fish weather or not they feel pain because you would have to inflict pain on the fish, and that could bring up a lot of opposition on weather or not its okay to do harm to animals in studies —Preceding unsigned comment added by 70.231.237.199 (talk) 01:55, 22 January 2008 (UTC)

[edit] more info needed on

the differences between a saltwater fish and a freshwater fish. Oidia 11:06, 2 June 2007 (UTC)

There isn't a difference. If you find a fish in the sea, it's a saltwater fish. If you find it in freshwater, it's a freshwater fish. The distinction is one of physiological adaptation: some fish can live in both fresh- and saltwater habitats, while others are restricted to either freshwater or saltwater habitats. The former, able to adapt to changes in salinity, are called euryhaline fish. The latter, unable to tolerate changes in salinity, are stenohaline fish. Most fishes are stenohaline, for example minnows (in freshwater) and most sharks (in the sea). But a sizeable number are euryhaline, either because their life cycle involves migrations between freshwater and the sea (e.g. salmon) whereas others simply move between freshwater and the sea in search of food (e.g. bull sharks). I agree this needs to be explained in the text. Cheers, Neale Neale Monks 11:16, 2 June 2007 (UTC)

[edit] How do they get into remote poop, tang?

Please add a section mentioning how fish manage to get into the remotest water storage tanks (where they end up transparent due to no light -- why too?), and freshly dug hilltop ponds. Eggs clinging to birds feet? Thus into the pond and down whatever pipe into the tank from any surface water? Jidanni 23:53, 9 July 2007 (UTC)

[edit] Human Face Fish

Some help in improving this article would be appreciated. Thanks. — EliasAlucard|Talk 15:32 23 Jul, 2007 (UTC)

I've clarified the science a little. It isn't a new species. It isn't a hybrid. It doesn't have the facial features of a human. It's a type of ornamental carp, a cross between two varieties of Cyprinus carpio (specifically, the common variety and the leather carp variety). The only human-like feature is the markings on its head and perhaps its head shape under certain lights. This is as unremarkable as the tomato with a rosary of seeds on the inside or the potato that looked like Richard Nixon. Cheers, Neale Neale Monks 09:41, 23 July 2007 (UTC)
Please continue this discussion on its talk page — EliasAlucard|Talk 18:16 23 Jul, 2007 (UTC)

[edit] Mention ancient heritage in intro?

The intro doesn't currently point out that fish are some of the oldest creatures in Earth's history. Should this be added? Chris Cunningham 16:58, 25 October 2007 (UTC)


[edit] Scientific classification

Why does this article not have the scientific classification-box? —Preceding unsigned comment added by Mweites (talk • contribs) 20:05, 8 November 2007 (UTC)

Read this section, "Unlike groupings such as birds or mammals, fish are not a single clade but a paraphyletic collection of taxa, including hagfishes, lampreys, sharks and rays, ray-finned fishes, coelacanths, and lungfishes.", i.e. in laymans terms, fish is all over the place in the taxonomic tree, see Chordate, Chondrichthyes are fish, but not Tetrapoda, Myxini/hagfish is fish but not Conodonta, so what would you put in the taxobox. Good question, I learned something new today!!! --Stefan talk 14:11, 6 February 2008 (UTC)

[edit] Peer review

Hello, I have requested a peer review of this article (which can be found here.) Thank you Cocoaguy ここがいいcontribstalk Review Me! 15:22, 17 November 2007 (UTC)

[edit] not all fish have scales

the article's intro implies to the contrary--Ted-m (talk) 01:18, 29 January 2008 (UTC)

[edit] Fish body shapes

I was trying to look up some info regarding the common body shapes of fish, but found no entries that were helpful. I was wondering if a section on this topic could be added somewhere. I know 4 terms have been used, but don't know if they're still used. Below are the terms, but I don't know if I have the right definitions/examples of each (if this terminology is even used, anymore).

To the best of my knowledge:

Fusiform is torpedo-shaped; ex. is a tuna, Compressiform is laterally compressed; ex. most fish, Depressiform is dorso-laterally compressed; ex. halibut or flounder, & Anguilliform is Eel-shaped.

Please comment. Thanks! Leia tyndall (talk) 20:37, 5 February 2008 (UTC)

[edit] Plural of fish

Am I wrong in thinking that there is no such word as "fishes"? I always thought the plural of "fish" was "fish" yet Wikipedia has many instances of the word "fishes". Should they be changed to "fish"? 1dragon (talk) 10:37, 7 February 2008 (UTC)

Read the terminology section (10.1) of the article --Graminophile (talk) 17:24, 7 February 2008 (UTC)
Aha! That's interesting. Thank you, 1dragon (talk) 10:48, 8 February 2008 (UTC)

[edit] Clarification

Does fish has Cloaca or separated posterior openings for the intestinal, urinary, and genital? Idvash (talk) 17:00, 20 February 2008 (UTC)

[edit] Pain reception in fish: "Other researchers"

I'm removing the following sentence from the article:

Other researchers say the question of pain in fish is difficult to answer as fish "pain" may be felt differently than human "pain."[2]

Although cited, the reference is not an authority or a reliable source. Further, the point being made is trivial, and understated at that. It's rather naive to attribute the observation to "other researchers" -- as if any scientist working in the area could think otherwise! Melchoir (talk) 08:37, 20 March 2008 (UTC)

[edit] goldfish that can't dump their eggs

I have a female that is absolutely bursting with eggs. Is it possible that she has no channel to the outside? Can I do anything to help her? I'm a first time visitor, so if I have committed a boo-boo, please forgive, but I don't know who to ask or where to go to for information. Margaret207.118.166.4 (talk) 23:27, 21 March 2008 (UTC)

Sorry but this isn't the best place to go. Try somewhere else. This isn't too big of a problem though so dont worry too much. DPM 15:32, 9 June 2008 (UTC)
