Use of low-cost equipment for growing commercial sturgeon fish

Abstract

The paper describes alternative low-cost equipment (in-ground pools) for keeping juvenile sturgeon fish. The results of the study of the hydrochemical regime of the compared fish breeding tanks, growth rates, and fish breeding and biological indicators of the juvenile fish contained in them are described. The object of the research was the juvenile bester (yearlings). As a result of growing fish in the compared containers, it was revealed that when using traditional type and frame pools there was no significant difference between fish breeding indicators. Compared fish breeding tanks provide the necessary hydrochemical regime for the cultivation of physiologically valuable juveniles of sturgeon fish with high growth rates. However, when keeping a yearling of the bester in the developed in-ground pool, there was a certain tendency to increase the intensity of fish growth. The concrete in-ground pool, in comparison with the compared fish breeding tanks, is not only the most reliable, but also close to the natural habitat of the fish (ponds) due to its high noise isolation and low vibration from fish life support system elements. It can be designed in any shape and size, placed anywhere. From a sanitary and environmental point of view, concrete pools are the most preferred option.
