Problems solved by technology

[0003] Aiming at the problems in the prior art that the seed source of white prawns is not fixed and the culture yield is unstable, the purpose of the present invention is to provide a kind of high-efficiency earthen pond ecological breeding and cultivation method of white prawns. The present invention selects artificial breeding broodstock, And by adopting the breeding pond to simulate the marine natural ecological environment conditions, the seed production can be increased by 20-30%, and the breeding survival rate is also improved by 10-15%, which solves the problems of low yield and low yield of wild white shrimp cultivation in the prior art. poor quality problem

Embodiment 1

[0035] The high-efficiency earthen pond ecological seedling raising and cultivating method of white prawn of the present invention comprises the following steps:

[0036] 1. Parental shrimp selection: The parental shrimp selected in the present invention is artificially bred white prawn, and the selected parental shrimp must meet the following conditions: complete appendages, smooth body surface, strong health and vitality, no specific pathogens, no Mechanical damage; large size, body weight ≥ 2.5g, body length ≥ 50mm; test for vibriosis and ciliate disease, and test for white spot syndrome virus (WSSV) to ensure that the parent shrimp does not carry the above-mentioned specific pathogens.

[0037]2. Overwintering indoors: In November of that year, when the natural seawater temperature was 10°C-15°C, the broodstock shrimp entered the pond for overwintering. Before the broodstock shrimp entered the winterization pond, the overwintering pond and the broodstock shrimp needed to be...

Abstract

The present invention provides a kind of earthen pond ecological seedling cultivation and cultivation method of white prawn, comprising the following steps: (1) selection of parent shrimp, (2) overwintering indoors, (3) intensive cultivation, (4) pond arrangement and cultivation of parent shrimp, (5) Seed cultivation, (6) Shrimp seed out of pond, (7) Breeding management, (8) Breeding harvest. The present invention selects and breeds broodstock artificially, and adopts breeding pond to simulate the marine natural ecological environment condition, can improve seed production 20-30%, culture survival rate also improves 10-15%, solves the ridge tail existing in the prior art The problem of low yield and poor quality of white shrimp wild seedling cultivation.

Description

technical field [0001] The invention belongs to the technical field of cultivating and cultivating white shrimp artificial seedlings, and in particular relates to a high-efficiency earth pond ecological seedling raising and breeding method for white shrimp. Background technique [0002] Exopalaemon carinicauda (Exopalaemon carinicauda), also known as white shrimp, small white shrimp and winter jasmine, belongs to Arthropoda, Crustacea, Decapoda, Palaemonidae, white shrimp The genus (Exopalaemon) is mainly distributed in the shallow sea and low-salt waters along the entire mainland of China and the west coast of the Korean Peninsula. The Bohai Sea and the Yellow Sea have the highest production. It is one of the three unique economic shrimps in China. Its production is second only to Chinese shrimp (Fenneropenaeus chinensis) and Chinese hairy shrimp (Acetes chinensis). Due to its strong reproductive capacity, fast growth, wide environmental adaptability, and delicious meat, i...
