The importance of Azolla aquatic plants in creating a natural sustainable nutrient environment in the fisheries industry

Abstract

The article analyzes data on the cultivation of Azolla in different nutrient media and economic efficiency in fisheries. Azolla has a high nutritional value compared to other aquatic plants because it is a source of protein with almost all the essential amino acids needed for animal nutrition. In the selected nutrient medium, the green mass of Azolla increased several times. Technical regulations have been developed for growing Azolla in different nutrient media in open conditions. The results of a chemical study of the green mass of Azolla showed that in the selected nutrient medium the proportion of protein increased several times. This study analyzes the efficiency of feeding nile tilapia with Azolla one of the aquatic plants.
