Intercropping mode of globefish and portunid

Abstract

The invention relates to an intercropping mode of globefish and portunid. The mode includes the following steps of after the National Day, collecting and temporarily cultivating the fresh portunids ina seawater earth pond or factory workshop; after the globefishes are transferred to the workshop, transferring the portunids to a cement pond of a globefish workshop; stocking the portunids accordingto the intercropping specification of 1.5 to 2 jin of portunids (each being 3 liang or above) per square meter; controlling the water depth of the cement pond in the workshop to be 0.8 to 1.8 meters;changing the water once every 2-3 days, each time the water volume being half of the water in the pond; exchanging ponds for trash removal once every half a month, wherein when the water level dropsto 40 cm, the portunids and globefishes are fished out, and put into an adjacent breeding pond, and then the pond is washed and disinfected; feeding according to the globefish stock, wherein the portunids are not fed separately; controlling the water temperature according to overwintering requirements of the globefishes; before the New Year's Day, selling the portunids successively until after theSpring Festival. The mode of the invention uses overwintering ponds of the globefishes to carry out portunid intercropping production, and achieves the goals of saving resources and improving qualityand efficiency.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a model for nesting puffer fish and swimming crabs. Background technique [0002] Puffer fish and portunus are important products of mariculture in coastal areas of my country, and the monoculture technology of the two is relatively mature. Puffer fish (red-fin puffer) is also one of the agricultural products that earn foreign exchange through export. With the limited liberalization of the domestic market, its breeding scale is also increasing in an orderly manner. Unable to adapt to the low temperature environment, puffer fish need to enter the factory workshop for overwintering or breeding at the end of October or early November every year. Swimming crab is a large-scale marine crab that grows in the Yellow Sea and Bohai Sea region of my country. It is of good quality and high price. However, the breeding and fishing of swimming crab is very seasonal, and it is listed on t...

AI Technical Summary

Problems solved by technology

Swimming crab is a large-scale marine crab that grows in the Yellow and Bohai Sea regions of my country. It has good quality and high price. However, the breeding and fishing of swimming crabs are very seasonal. They are listed on the market every autumn, and the economic benefits are low.

At the same time, the swimming crabs harvested in the early stage are in the shelling growth stage, and the swimming crabs with low plumpness account for a large proportion, and the commodity value decreases

Therefore, it is a good way to improve quality and efficiency by collecting portunus crabs with low plumpness in autumn and temporarily raising them for fattening
