Embodiment 1

[0027] Embodiment one, taking Changyi City Haifeng Aquaculture Co., Ltd. as an example to introduce the specific implementation of the present invention:

[0028] 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 vitality, and no mechanical damage; large size, heavy weight ≥2.5g, body length ≥50mm; test for White Spot Syndrome Virus (WSSV) to ensure that the parent shrimp does not carry pathogens, and the parent shrimp is strictly disinfected before entering the pond. The disinfection method is: first use 15ppm of Potassium permanganate disinfectant bath for 2-3 minutes.

[0029] 2. Indoor overwintering pool: In November of that year, broodstock shrimp entered the pond to overwinter. Before entering the overwintering pool, the overwintering pool needs to be strictly disinfected. The disinfectio...

Embodiment 2

[0035] Embodiment two, introduce as an example with the Xiaying Multiplication Experimental Station of the Chinese Academy of Fishery Sciences:

[0036] Broodstock shrimp selection and the operation of indoor overwintering pond are identical with above-mentioned embodiment.

[0037] Overwintering management: After broodstock enter the pond, the density is controlled at 350 tails per square meter; the light intensity is controlled below 500lx, and a 1.5-meter-diameter shrimp nest made of forked branches is evenly placed every 5 square meters along the edge of the pond; bait The bait is mainly clams, Philippine clams, squid and other baits, which are mixed and fed. The feeding amount is 5% of the body weight of the broodstock. In the following year, the statistical survival rate was 82.5%, and the gonads were well developed. Using this groundwater method can achieve energy saving and emission reduction, while cutting off the transmission of pathogens in natural seawater. Pract...

Abstract

The invention provides an indoor overwintering method for a palaemon carinicauda parent. The indoor overwintering method for the palaemon carinicauda parent comprises the following steps of selecting and processing a parent overwintering pond, controlling the parent ratio, density and water temperature, and performing the overwintering period feeding management technology. The indoor overwintering method is an overwintering method suitable for the palaemon carinicauda biology, behavioristics and ecology. According to the method, the overwintering survival rate of the palaemon carinicauda can be improved to a larger extent, the overwintering survival rate can be above 80%, and the expenditure can be saved by 30%. According to the indoor overwintering method disclosed by the invention, diseases can be prevented from spreading, the coal use amount is reduced, energy saving and emission reduction can be realized, the overwintering survival rate and the economic benefit are improved, and the technical guarantee is provided for the breed conservation of the superior clones of the palaemon carinicauda. The indoor overwintering method is favorable for accelerating the healthy and sustainable development of the palaemon carinicauda breeding industry in China.

Description

technical field [0001] The invention belongs to the technical field of broodstock overwintering of white prawns, and in particular relates to an energy-saving wintering method for white prawns in ground water. 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, in recent years, with the development of coastal ...
