Instructions
Step 1
If there is a reservoir on your garden plot, then you need to thoroughly clean it and put it in full order. In the absence of it, you can dig it yourself. The size and depth will only depend on you. A regular pool is also suitable for breeding sterlet.
Step 2
For the convenience of growing fish, use special cages. We must not forget that the sterlet is an open-bubble fish and during the open water period it comes to the surface to swallow the necessary portion of air. It will be most expedient to breed it in open cages.
Step 3
Fill the pond with groundwater or rainwater. The oxygen content in it should be at least 5-6 mg / l, and the optimum temperature is 20-22 ° C. Periodically, the water should be changed, such a procedure must be carried out within twenty-five days.
Step 4
Buy grown fry. You need to purchase them between May and September. This is best done in special farms that breed these fish. Such fry will be the most resistant to various types of human intervention in their lives and less stressed.
Step 5
It is recommended to feed young sturgeons several times a day with daphnia, larvae of various insects, small crustaceans, and then with shells. Crustaceans are the main food of the adult sturgeon. Keep track of the amount of feed, there should not be too much of it.
Step 6
When transplanting fish to a wintering place of residence, it must be kept in five percent salt water for several days. This is necessary in order to destroy all parasites that can get into the wintering reservoir along with the fish.
Step 7
In winter, at low temperatures, the fish hibernates. She should be provided with a state of complete rest, since if she is awake, she will begin to expend energy and quickly lose weight.
