Description

technical field

[0001] The invention relates to the technical field of aquaculture, in particular to an environment-friendly prawn nursery method using chaetoceros. Background technique

[0002] With the development of aquaculture industry, its impact on the ecological environment has attracted more and more attention. In recent years, more and more elements of environmental protection have been considered in the improvement of aquaculture technology, and technologies such as fully enclosed, circulating water, and zero sewage have been invented successively. These technologies are more engineering-based, and most of them are based on equipment renewal basis. The shrimp nursery technology that realizes environmental protection by simply utilizing the relationship between organisms and establishing a controllable and friendly ecosystem has not yet been developed.
