Title: World’s biggest freshwater fish?
Post by: clarki on June 20, 2022, 11:58:14 PM
I’m curious why this stingray is called the world’s largest freshwater fish

When Fraser River white sturgeon weigh well in excess of that. For example, this one

Is it b/c sturgeon might be anadromous, or sport caught sturgeon weights are estimates, or just a case of my country is better than yours?

Clarki I, I think that they purposely leave out the “scaled” description. I ran into the same question on the arapaima and their answer was that sturgeon don’t have scales while the arapaima does and, apparently, the ray has something called micro scales. Just marketing.

I’m sure the lack of a precise number with sport caught fish has something to do with it. I think the point that sturgeon aren’t strictly freshwater is a better explanation because you could theoretically also justify something like a bull shark as a freshwater fish if you stretched the definition

It is because sturgeon don't exclusively live in freshwater. I read a few articles on this stingray and that was mentioned in all of them as the reason this is considered the largest.

there are many sturgeon populations both in North America and Eurasia that are landlocked and so cannot be anadromous. Some are landlocked by dam construction and some by geology.

So I guess if there was a reliable and accepted way to weigh C &R sport caught fish, and tissue sampling to prove that a fish from the Lillooet reach of the river did not migrate to the ocean during its life…THEN we could lay claim to the world’s largest freshwater fish.

To borrow from The Princess Bride, that would be a noble quest!
