size of lake stuergeon in captivity

[catfishmaniac]

does anyone know how big lake sturgeon (Acipenser fulvescens) get in captivity?

From the wiki page on them:

The lake sturgeon can grow to a mass of over 100 kilograms (200 lb) and a length of over 3 meters (9 ft) over its long lifetime.

Captive size shouldn't be much smaller unless you're housing them in less than ideal conditions and stunting their growth.

People can buy sturgeons!?

I would not do it. You can not keep it in a tank. Would need a VERY large pond.

And if you ever got sick of keeping it, good luck trying to rehome it.

If you want a big fish, get a koi. Much easier to work with.

9 feet was max for the specific breed the OP asked about: Acipenser Fulvescens

Some sturgeon can get near 20 feet as you said, and over 600 lbs. Live for hundreds of years.

I was just pointing out that captive size shouldn't be much different than wild size unless you're stunting it's growth somehow. But yeah, you'd need a huge pond (small lake) to keep most types of sturgeon long term.

im digging a very large pond (40,000 gallons) and i think thats big enough

 

[Dark Jester]

Yeah, that'll do. If it's not happy in that, there's no pleasing some fish.

Nah, not all of them. Though in some states it is illegal to posess any of them, Idaho is one. Along the lower snake/colombia rivers, if you catch one you aren't allowed to take it out of the water. Washington probably has the same rule, but don't quote me on that.

There are some bred in captivity though, or wild caught in areas where they are not endangered.
