Method for ecologically breeding stichopus japonica, siganus oramin and jellyfishes in pond of Yellow River delta area

Abstract

The invention provides a method for ecologically breeding stichopus japonica, siganus oramin and jellyfishes in a pond of the Yellow River delta area and belongs to an aquaculture method. When water temperature reaches 16-18 DEG C in later April, 900-1100 siganus oramin young fishes are put into each mu of water in the stichopus japonica breeding pond, a net cage is defined by a filtering screen in the middle of the stichopus japonica breeding pond, and 30-50 jellyfish young fishes with the diameter being 1.5-2.2 cm are put into every cubic meter of water; after breeding is conducted to early November, water temperature of the pond is reduced to 14-16 DEG C, siganus oramin is harvested, and in the breeding process, the jellyfishes are harvested twice. By means of the ecological breeding method, stichopus japonica, siganus oramin and jellyfishes are bred in a mixed mode; the characteristic that siganus oramin and jellyfishes eat alga and protozoa in the stichopus japonica breeding pond is used, so alga and disease organisms of the stichopus japonica breeding pond of the Yellow River delta area are effectively inhibited; good quality of the stichopus japonica breeding pond is maintained, yield increase of stichopus japonica is achieved, and the environment problem caused by stichopus japonica breeding is alleviated..

Description

technical field [0001] The invention relates to an aquaculture method, in particular to an ecological aquaculture method in which sea cucumbers, basket fish and jellyfish are mixed. Background technique [0002] In recent years, the sea cucumber breeding industry has developed rapidly, and the sea cucumber breeding area has continued to increase. However, the cultured species of sea cucumber in ponds is single sea cucumber, and the breeding of algae and protozoa in the ponds is relatively fast. In order to increase the production of sea cucumbers, illegal farms abuse antibiotics, herbicides and other drugs to remove algae and the ammonia nitrogen and toxins produced by the algae, resulting in serious drug residues in the cultured sea cucumbers and poor quality of cultured sea cucumbers. The sea cucumber breeding ponds in the Yellow River Delta region have special geographical and ecological environment characteristics, mainly due to low tidal range, soft bottom, high degree...

Problems solved by technology

Frequent spraying of herbicides will not only increase the cost of breeding, but also cause drug residues in sea cucumbers, causing environmental pollution
