3 new Black sturgeon!

[Wiggles92]

The rate of sturgeons growth, and the rate of an RTC are completely different as well. Your RTC will grow a ft before those sturgeons do.

Here are growth rates:

In a pond situation rough growth rates should be approximately:

• Siberian: 90cm (3ft) in 5-6 years
• Diamond: 90cm (3ft) in 4-5 years
• Albino Sterlet: 60cm (2ft) in 5-10 years
• Sterlet: 90cm (3 ft) in 8-10 years

This is a great site for info!

I have been seeing auctions on Aquabid for the Siberian sturgeons, and now I'm tempted to bid on one of them after seeing that they can get pretty big.

What temps they can live at depends on the species of sturgeon, a shovelnose sturgeon should live quite well at temps in the high 70's even low 80's but a Siberian or white sturgeon would not do well at temps that high. As for the RTC, if I remember the OP he is in MD? unless the pond in quite well sheltered you are going to be hard pressed to keep your fish at 68 and while a RTC might live at that temp it is not exactly his optimum temp. I've had iridescent sharks survive temps down to less than 60 but they just sit and do nothing. I suspect your RTC will do the same thing. Shovelnose sturgeon top out at 4 feet but even in the wild such large fish are rare, most shovelnose sturgeon are in the 24" to 30" range in the wild and breed smaller than that. Siberian sturgeon on the other hand are true giants, getting 20 feet or more according to some sources. White sturgeon are cold water fish and quite large not only in length but in girth and weight as well. Sterlets are similar in size to shovelnose but need a freshwater salt water interface to really be healthy, they are brackish water fish in the wild much like Atlantic shortnose sturgeon, they travel back and forth between fresh and salt routinely and not just for breeding like other anadromous fish

I know people who have kept sterlets for year (10+) and have kept them in solely freshwater, with no ill affects what so ever.

I know people who claim to have kept sharks in solely freshwater for many years too, doesn't make it true... I didn't say they had to have brackish water just that in the wild they live near and in the freshwater-salt water interface and do better if kept in brackish water. Kept in "solely" freshwater they are prone to gill parasites. They are native to the Black and Caspian Seas which are salt water. NC prohibits the importatipon or possesion of sterlets due to the fear they will be released and replace the native shortnose sturgeon.

Just because someone claims to have kept a fish for 10 years doesn't mean they did or that the water didn't contain considerable amounts of salts.

I personally know these people. So, I know that they are not lying about them.

Any fish is prone to gill parasites if you introduce them into the living space of that fish.

I don't live in NC- they are legal in my state.

Yeah, all I know about sterlets is what I've been told too...

Demonstratively false... You really cannot eliminate all parasites, you only suppress them until the fish can beat them, if not the fish dies but the parasites always remain.

Enjoy them, I probably would...

Stop being such a D---. It's really not necessary.

I personally know these people, and I know that they would not lie about this.. One of them happens to own a large koi forum, and he makes more $$ than Bill Gates. He's got imported koi worth more than people's cars.

And you can eliminate all parasites that would affect a fish's health. If you are having parasite issues, then you aren't doing something correctly.
