Bait breeding method of sediment pool bechedemer

Abstract

The invention relates to a method for cultivating the bait of stichopus japonicus selenka in a costal sediment pond. The bait cultivation is carried out from April to May, which comprises that: (1) after the toxicity of the medicine for cleaning the pond fades away, the water in the pond is discharged; the water with the height being 30-50cm is injected again; and 0.075kg / m<2> of organic fertilizer and 0.003 kg / m<2> of chemical fertilizer are put in the pond; (2) when the depth of the inlet water in the pond reaches 80-90cm, demersal diatom is transplanted, 5-10l / mu of algae solution can be transplanted, and carbamide can be put in as per 0-1kg / mu; (3) Ruppia maritime and algae gammarid are transplanted. The Ruppia maritime is uprooted and transplanted integrally as per the quantity of 5-15 plants / m<2>; after the Ruppia maritime is transplanted, the algae gammarid is transplanted as per 1.5-3kg / mu. The beneficial effects of the invention are that not only the raised stichopus japonicus selenka has excellent quality, but also the incidence of diseases is low, the cultivation period is short, the survival rate is improved, therefore the method of the invention has vast promotion prospect.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a bait cultivation method for japonicus japonicus in coastal muddy ponds. Background technique [0002] As a kind of sea cucumber, sea cucumber has high edible and medicinal value, and is a traditional valuable seafood in my country. At present, the natural production is very small. Due to its ecological characteristics, its natural distribution and breeding area are narrow. In the past, breeding ponds were only built on the shore of rocky reefs or sandy shores with smooth currents. At the same time, due to the narrow breeding area, the density of breeding ponds was too high. , leading to more diseases in recent years, the yield, quality and benefit of sea cucumber farming have declined sharply, seriously affecting the development of sea cucumber farming. [0003] However, my country has a large number of muddy coasts and tidal flats. Due to the limitation of natural envir...
