Embodiment 1

[0024] In this example, in 2013, Shandong Rizhao Kaihang Aquaculture Co., Ltd. carried out multi-crop cultivation of white prawns and crabs with good results.

[0025] A continuous multi-crop artificial culture method for white prawns in one year, including parent shrimp selection and indoor overwintering, overwintering breeding of parent shrimp with eggs, stocking of brood shrimp ponds with eggs, harvesting of the first batch of cultivation and selection of parents, and harvesting of the second batch of cultivation or At the same time, the parents were selected and the third batch of breeding was carried out.

[0026] 1. Broodstock selection and indoor overwintering In early November 2012, male and female white prawns that do not carry infectious pathogens and have strong vitality were selected from artificial breeding ponds as overwintering broodstock. Move it into the indoor overwintering cement pool; add sand to filter the ground seawater 20-30cm in the overwintering pool,...

Embodiment 2

[0038] The present embodiment is cultured according to the prior art. In mid-June, the white prawns and the portunus trituberculatus are polycultured. Other culture conditions are the same as in Example 1. After 5 months of breeding experiments, the breeding results are as follows: the yield of white prawns harvested is 80kg / mu, and the output value is 3200 yuan / mu; the harvested yield of swimming crab is 55kg / mu, and the output value is 4400 yuan / mu; , output value 7600 yuan / mu, economic benefit is not as good as embodiment 1.

Abstract

The invention discloses an annular continuous multi-batch artificial culture method for palaemon carinicauda, belonging to the technical field of aquaculture. The method comprises the steps of selection and indoor wintering of parent shrimps, wintering incubation and parent shrimp rearing, pond stocking of incubation parent shrimps, first-batch culture harvest, parent selection and remaining, second-batch culture harvest or simultaneous parent selection and remaining and third-batch culture. Through indoor culture of parent palaemon carinicauda, incubation parent shrimps are obtained in advance. By reasonably arranging the parent shrimp stocking and commodity shrimp harvest time, annular multi-batch culture is realized, and the utilization ratio and economic benefit of a culture pond are increased. Two-batch culture is realized annually in the provinces of Shandong, Jiangsu and Zhejiang in China, and three-batch culture can be realized in regions south of Guangdong province in China.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an artificial breeding method for white prawns with multiple crops in one year. Background technique [0002] At present, marine shrimp farming at home and abroad is dominated by prawns, mainly including Chinese prawns, Litopenaeus vannamei, Penaeus monodon, Penaeus japonicus and other species, and the species of the genus Pleurotus is a new aquaculture species. [0003] White shrimp (Exopalaemon carinicauda Holthuis, 1950), also known as white shrimp, small white shrimp and winter jasmine, belongs to Arthropoda, Crustacea, Decapoda, Palaemonidae , white shrimp (Exopalaemon), mainly distributed in the shallow sea and low-salt waters along the coast of mainland China and the west coast of the Korean Peninsula, with the largest production in the Bohai Sea and the Yellow Sea, second only to Chinese shrimp (Fenneropenaeus chinensis) and Chinese hairy shrimp (Acetes chi...
