Ecological method for breeding South America white shrimps

Abstract

An ecologic reproduction method for the South-American white prawn features that a lighting method is used to culture parent sprawns. After the illuminance is increased, the water quality is improved and the algae can grow on the inner surface of culturing pool for meeting the requirement of parent prawns.

Description

technical field [0001] The invention relates to a shrimp fry breeding technology in the field of aquaculture, in particular to an ecological breeding method of Penaeus vannamei. technical background [0002] Penaeus vannamei is also known as Penaeus vannamei, Penaeus vannamei, and Penaeus vannamei. Its scientific name is Penaeus vannamei Boone. At present, the dark method is generally used in the cultivation of Penaeus vannamei broodstock, see the local standard of Guangdong Province "Artificial Propagation Technology of Penaeus vannamei Farming Technical Specifications" (DB44 / T229-2005). This standard stipulates the environmental conditions for artificial propagation of Penaeus vannamei, the technology for accelerating the ripening of broodstock shrimp, the mating and spawning technology of broodstock shrimp, and the hatching technology. In the dark breeding method, the light intensity is below 1000Lx. During the breeding process of broodstock, such as temporary breeding o...

AI Technical Summary

Problems solved by technology

In the dark propagation method, the light intensity is below 1000Lx. During the broodstock cultivation process, such as temporary breeding of broodstock, ripening cultivation of broodstock, and mating of broodstock, the light intensity is controlled at 500Lx~1000Lx. The bottom and wall of the pond are very clear and bright. However, high turbidity in the water is required, which often leads to excessive water quality, which is not conducive to the growth and reproduction of broodstock shrimp, and the reproductive effect is not ideal
