Industrial shrimp larva breeding mode

Abstract

The invention provides an industrial shrimp larva breeding mode capable of improving production benefits and market benefits of larva breeding, which is characterized in that: (1) a breeding device consists of a constant temperature heating device, a hatching pond and larva breeding ponds; (2) multiple stages of high-low serially connected larva breeding ponds are communicated by transfer pipes; (3) water inlet pipe of the hatching pond reaches the bottom of the hatching pond from the center of the hatching pond, and the upper end of the water inlet pipe is connected with the constant temperature heating device; (4) after being hatched in the hatching pond, larvae enter a next stage of larva breeding pond through a communicating pipe with water flow till the larvae are well gown; (5) eachstage of larva breeding pond is provided with a water injection pipe; (6) circulating water of all stages gathers in a return pipe, is processed in a sterilizing pond and circulate to the constant heating device again. The high-density and systemically controlled-breeding condition industrial shrimp larva breeding mode has the advantages of water conservation, small floor area occupation, high breeding efficiency, light environmental pollution and the like and greatly improves the production benefits and market benefits of larva breeding.

Description

technical field [0001] The invention relates to a new mode of industrialized breeding and breeding of shrimp seedlings, which belongs to the technical field of aquatic seedling raising. Background technique [0002] At present, the single-pond structure is usually used in the breeding process of shrimp seedlings. Due to the high breeding density and large amount of feeding in this model, a large amount of residual bait and feces will be produced during the breeding process, especially in the middle and late stages of growing shrimp seedlings. The growth of bait and shrimp excreta all increase significantly, and the pollution of the water body itself will also increase significantly. Water pollution will cause outbreaks of shrimp diseases and ultimately affect the emergence rate. [0003] Industrialized recirculation aquaculture is a high-density and systematically controllable aquaculture model. It has the advantages of water saving, less land occupation, high aquaculture ef...

[0002] At present, the single-pond structure is usually used in the breeding process of shrimp seedlings. Due to the high breeding density and large amount of feeding in this model, a large amount of residual bait and feces will be produced during the breeding process, especially in the middle and late stages of growing shrimp seedlings. The growth of bait and shrimp excrement will increase significantly, and the pollution of the water body will also increase significantly. Water pollution will cause outbreaks of shrimp diseases and ultimately affect the emergence rate.
