Worlds largest freshwater fish

[synodontisjack]

Yeah but were looking for the worlds largest FRESHWATER fish all the larger species are migratory (move from fresh and salt/brackish water)

 

[lincolngoh]

yeh but wats the criteria??? weight? height? length?
i think it shud be weight therefore freshwater stingray WINS

Maybe should measure by length and breath or surface area

... Stingray should win.

 

[synodontisjack]

How about we find the average of height and length so if the stingray gets 1000lb and is 9ft length it would be 4500 and arapaima 700lb and 18ft so it wold be 6300

Or Sturgeon?

The white sturgeon, Acipenser transmontanus, sought by sportsmen on the Columbia and elsewhere along the West Coast, is the largest freshwater fish found in North America, attaining as much as 1,800 pounds and 20 feet in length.

Thought they aren't 100% fresh water?

Is the worlds largest freshwater fish thread dead or not, everyone put their final decisions as to what they think

 

[snakeheader]

I think its some kind of catfish or the giga

 

[flemming]

in de 19and 20ste century many big fish where caugth and killed,the population big fish is nearly gone,but if we give some fish the chance they wil become very huge.
european catfish(15feet)
sturgeon(15/19feet)
airpaima(20feet)
mekong catfish(15feet)
alligator gar(14feet)
we just need to give the fish the chance and the habitat to grow to hug sizes

I've got a fish book that says one type of sturgeon gets 29 feet long...I don't believe that though. I've never seen any pictures of arapaima larger than 5-6 feet, although I don't doubt that they get much larger than that.

I think the book means they used to get that big. And still could. But it takes them so long (100+ years) we kill them long before.
I don't see giant trees anymore either. But that's only because we keep cutting down the juveniles.
