According to the link in Fasertheking's post, this is a FW ray that reaches 1,000 lbs.



... and this is a really big freakin sturgeon.

a fw ray would have to be huge to top 1000lb as they are not deep bodied and i doubt any river system could support something that big, the sturgeon is migratory

Hey, I'm just reporting what I read on the National Geographic site in his link.

It does seem a bit far fetched though. However, I don't see a problem with a 1000lb fish in some of the world's largest rivers though. I would say that it's entirely possible, even if not for a FW ray specifically.

Well, if we are looking at fish that go back and forth from fresh to salt - we need to count bull sharks. Isolated populations are suck in 100% freshwater for their entire lives. Adult bulls can weigh in close to 1000 lbs.

True, I believe my Dad's cousin caught one in the lower Mississippi when he was younger. That would be a bit of a surprise if you were fishing for cats! :eek:

A blue whale is not a fish it is a mammal !
