Siberian Sturgeon Acipenser baerii

Off the several species of sturgeon suitable for the garden pond the Siberian Sturgeon is the most commonly available, and amongst the hardiest.

Lake Sturgeon

While' st I did say "suitable for garden ponds", I should perhaps qualify that statement by mentioning that they do get quite big, so medium to largish ponds are better.

In the wild they can reach 2M and 150Kg plus, although a more modest 1 - 1.5M and less than 25Kg is more typical in a garden pond.

 

Generally a peaceful fish they are unlikely to molest other pond inhabitants, even smaller fish, although they can eat fry which don't move out of their way as they cruise the bottom and sides looking for snails and crustaceans. They should be fed on high protien pellets, even throughout the winter when other pond inhabitants have stopped feeding.

Native to cooler waters they like oxygen rich water and won't tolerate temperatures much above 25C. The also have great difficulty swimming in reverse and can become tangled in blanket weed which catches around their gills and suffocates them. As an added complication they are ultra sensitive to many treatments used control Algae and treat other pond fish.

Always check before using any treatment in a pond housing Sturgeon.

If medication is required then a Salt Bath is best as the first line of defence. Other safe treatments are Methyl Blue, Chloramine-T and Malachite Green.

*Warning* Potassium Permanganate, or Copper or Formalin based medicines are highly toxic to Sturgeon and should be avoided. As a general guideline only medicines safe for use with Orf should be used with Sturgeon.
