Koi carp and sturgeon question?

Question

I have a 40.000Gal Koi pond with 26 koi from 6" to 28" and a siberian sturgeon of 15". I have to feed the koi floating food at one end, then run and feed sinking pellets to the sturgeon. Has any got any suggestions on how i can get enough food for the sturgeon before the koi come along and have his food too?. And how large will it grow in a pond of this size?.
Many thanks

Answer 1

Cut a piece of PVC pipe long enough to reach the bottom of the pond. Pour the sinking pellets down this tube and allow them to sink to the bottom inside the tube where the Koi can't get to them.

The sturgeons size will be related to the dimensions of the pond as well as total gallonage, but if it's a typically designed pond I would expect he could very well get to the normal adult size of about 2 meters or roughly 7 feet. That assumes all of his needs are met of course.

Here's a rather technical but very informative article on feed rates and growth rates for Siberian sturgeon

Answer 2

most koi top out about 32-36 inches. and it is usually 2000 gallons per adult koi.

Sturgeons, i believe it depends on the species, but around40-70 inches.


Try using sinking foods or pond sticks.
