[edit] Largest freshwater fish?

I believe that the Arapima of the Amazon is in fact the worlds largest freshwater fish. David

-The arapaima is a very large fish, but they are not as large es the the mekong catfish, which is much bulkier and heavier. Furthermore there are several species of freshwater sturgeons and freshwater stingrays which grow also larger than the arapaima.

[edit] Giant Mekong Catfish

I tried adding the link to this article in this article but it doesn't work. the wikipedia article on Giant Mekong Catfish is all capitalized but when i put that link in the text it reverts it to lowercase and indicates that there's no such article.

[edit] Does anyone know how true it is that catfish can survive when lake is dry?

Some species are able to breath air and and "walk" short distances over land, but most catfish-species will simply die when their habitat dries out.

[edit] Largest Wels Catfish...

Fishbase says that wels catfish may be up to 5 metres in length and weigh up to 300 kg. The 'largest catfish caught' catcher seems to have missed a thing.

-In fact there are no prooves that a wels catfish of this dimensions ever existed. The largest specimens were about 2,70-2,80m, and had weights of 100-150kg. This shows also that the size and weight are in false relations, because a 5m long catfish would weigh much more than 300kg. It is sadly very common that authors copy "facts" from other authors without any research.

[edit] Catifsh law

I have heard recently that there is a proposed law in America that would legally define 'catfish' to exclude the species grown in Vietnam & SW Asia, who are the major source of catfish eaten in the US, for protectionist purposes. Has anyone here heard about it? Identity0 08:10, 29 December 2005 (UTC)

Yes, something came up in the House maybe 2 years ago that would have allowed the word catfish only be attached to products that came from Ictalurids. Of course this is bullshit, as "catfish" has always refered to Silurids on the whole, and this entire discussion is only coming about because Vietnamese Pangasiid ("basa") imports are starting to show up in supermarkets.

I heard that too.

[edit] Using catfish in septic tanks.

Catfish are used in septic tanks in Indonesia, to eat the waste and prevent the tank from filling up with solids too quickly. I can't find a valid source, so I'll just offer these links for now, and hope that someone comes up with a source. I might try and co-author a journal article on it next year, which would then be a valid source.

My comment: An Indonesian's comment on catfish in septic tanks

The Indonesian Wikipedia article on catfish mentions that freshwater catfish are used to remove impurities from water; it states that catfish used in the way must be cleansed before eating, by being placed in flowing water. (The article doesn't state how long for, or just how much this improves the taste & safety). --Singkong2005 · talk 15:28, 24 October 2006 (UTC)
