Abstract
Diets containing Azolla can be used to feed white worms as live feed for sturgeon. To reduce the cost of white worm production, it is very suitable to use a mixture of 60% Azolla, 25% wheat flour and 15% rice bran. During the cultivation period using Azolla, in order to achieve optimal growth, the humidity of the white worm breeding environment should be between 50 to 60% and the soil pH should be in the range of 6.4 to 7.6. The environment of the breeding bed is equal to the mixture of sawdust and leaf soil. To prevent the growth and development of earthworm eggs and larvae and other pests, the soil of the culture medium should be heated with water until the soil temperature reaches 50-60 °C. Azolla can be used as a cost-effective alternative and as a model for improving the breeding of white worm to increase the production of sturgeon.
