Many of the phrases from this article are exactly the same as those at other random web sites. I am rewording it slightly in order to stop any possible copyright violations. - Mark Ryan 17:07, 16 Dec 2003 (UTC)

Sorry.. didn't see your message before I started editing. If you think it's still too close to the lifted article(s), go ahead and rewrite again. I'll try to get a taxonomy box fixed up soon. Hadal 17:20, 16 Dec 2003 (UTC)
LOL When I got the edit conflict, I set about trying to merge both versions into one, but found yours was a better version than mine anyway. Just one issue: are you sure the depth figures are correct? the initial version said up to 3000 feet, not metres. A conversion of that gives me 975 metres. Also, isn't the toothfish caught in the Indian and Southern oceans too? That's where Australian Customs is always arresting illegal fishing boats... Maybe it'd be worth mentioning the illegal fishing of it... because it's a huge issue here, and a major reason why Australians don't like the Japanese much is because of their whale-killing and illegal fishing. - Mark Ryan 17:32, 16 Dec 2003 (UTC)
You're right, they're also caught in the Indian and Southern Ocean (I've added mention to it in the article). The depth figures were gleaned from here, which I for one consider an authoritative source. Added a bit on the illegal pirate fishing with a link to the BBC report. If you'd like to expand, please do.. you'd be more familiar with the situation than I could ever be by reading a few ecology websites. :) Hadal 18:19, 16 Dec 2003 (UTC)

[edit] Size

So the average catch size is 20 lbs but large specimens reach 440? Is this correct? Anchoress 19:39, 11 July 2007 (UTC)

The fish is 1-2 meters long, it must weigh far more than 20 lb. This page says the big ones are 120 kg, which is 265 lb. So i can believe 440 lb toothfish have been caught, but i have a hard time believing any adult could be only 20 lb. Can anyone else find any other sources on their size?

Maybe not, this page claims the average weight is only 10 lb. Since they live for many decades, continuing to grow, they must get quite big eventually but most fish caught are much younger. Foobaz·o< 00:22, 12 July 2007 (UTC)

I am a buyer for a large catering company and we use quite a bit of this fish - our average filets are over 10lbs - that would mean a fish yields 20 lbs of usable meat - these fish yield out at about 50% so that would mean the average fish is about 20K and not 20 lb >>tom gillespie 11-14-07

from DUHAMEL G., GASCO N., DAVAINE P., Poissons des îles Kerguelen et Crozet, p. 330 :
fish are common up to 110 cm (and big ones are known up to 215 cm)
relations between weight (kg) and total length = LT (cm) are :
weight (♂) = 33,343 ×10-4 x LT3,2601
weight (♀) = 31,978 ×10-4 x LT3,2685
transformation ratio for filets is 3.40 (so to give a filet of 10 lbs a fish is about 34 lbs)
