Pond alternate culture method for Chinese prawns and penaeus japonicus

Abstract

The invention discloses a pond alternate culture method for Chinese prawns and penaeus japonicus. The pond alternate culture method comprises the following steps that S1, preparation treatment is carried out; S2, algae culture fertilizer water and algae phase are balanced; S3, shrimp seeds are selected and put in; S4, culture management is carried out, a Chinese prawn pond and a penaeus japonicus pond are correspondingly managed according to a Chinese prawn culture method and a penaeus japonicus culture method; S5, alternate culture is carried out, after the penaeus japonicus is taken out of the ponds and sold, the Chinese prawn pond and the penaeus japonicus pond are dug through, then half of the Chinese prawns is put in the Chinese prawn pond into the penaeus japonicus pond, and then culture management is carried out on the Chinese prawns in the two ponds according to a Chinese prawn culture method; and S6, the Chinese prawns are taken out of the pond for sale. According to the pond alternate culture method for the Chinese prawns and the penaeus japonicus, the Chinese prawns and the penaeus japonicus are alternately cultured, the utilization rate of the pond is increased, the Chinese prawns and the penaeus japonicus are not affected, the production value per mu reaches 6000 yuan, the benefit per mu reaches 3000 yuan or above, and therefore the purpose of increasing production and income is achieved.

Description

technical field [0001] The invention relates to a prawn culture technology, in particular to a method for cultivating Chinese prawns and Japanese prawns in rotation in ponds. Background technique [0002] Chinese shrimp is one of the most representative aquaculture species in my country, and the breeding areas are mainly along the coast of the Yellow Sea and the Bohai Sea. The highest year of its aquaculture output (around 1990) once accounted for 70% of my country's prawn aquaculture output, reaching about 150,000 tons. But in the early 1990s, problems such as raging diseases and germplasm degradation have seriously affected the development of this breeding industry. The "Yellow Sea Series" of Chinese prawns bred by the Yellow Sea Fisheries Research Institute of the Chinese Academy of Fishery Sciences has injected vitality into the second venture of China's prawn farming industry and promoted the healthy development of China's prawn farming industry. [0003] The total ar...

Problems solved by technology

However, the single aquaculture model and low breeding efficiency restrict the development of aquaculture, that is, the Chinese prawn and Japanese prawn have a single aquaculture model and the aquaculture benefit is average.
