Problems solved by technology

Golden squid likes to eat live bait, and the pool water must be clear, which greatly limits the promotion of this species. The society urgently needs a high-yield, efficient, and environmentally friendly golden squid breeding model to solve the bait and water quality problems in the golden squid breeding process

Abstract

The invention provides an ecological mixed breeding method of a pond mainly used for breeding Sepia esculenta. The ecological mixed breeding method comprises the following steps: pond preparation: excavating a deep ditch in the middle of the pond, adding gentle slopes on the inner side of the periphery of the pond, covering each gentle slope by using a layer of geotechnical cloth, and paving PVC oxygenation pipelines on the bottom of the pond; stocking Meretrix meretrix Linnaeus seedlings in the pond when the temperature of water in the pond reaches 7-8 DEG C in the spring; stocking Exopalaemon carinicauda and shrimps with eggs when the temperature of the water in the pond rises to be 12-13 DEG C; stocking Sepia esculenta larvae after the temperature of the water in the pond rises to be 14-16 DEG C; and then feeding with baits in a combined manner. According to the ecological mixed breeding method provided by the invention, mixed breeding is implemented by ecological complementarity of the Sepia esculenta, the Exopalaemon carinicauda and the Meretrix meretrix Linnaeus, the Meretrix meretrix Linnaeus purifies water, the Sepia esculenta can eat the Exopalaemon carinicauda, the pond has Exopalaemon carinicauda groups in different stages, and requirements of the Sepia esculenta to live baits are met; and the Sepia esculenta eats sick and weak Exopalaemon carinicauda individuals, and spreading of shrimp diseases is controlled effectively, so that the purposes of high yield, high efficiency and environmental protection are achieved.

Description

technical field [0001] The invention relates to a method for polyculture of golden squid, in particular to an ecological polyculture method for mainly raising golden squid in ponds. Background technique [0002] Golden squid ( Sepiaesculenta ), also known as cuttlefish and mullet, are distributed in the Bohai Sea, the Yellow Sea, the East China Sea, the South China Sea, the Japanese Islands and the Philippine Islands. The golden squid is one of the most important economic species in the world squid family. Its annual output ranks second among the squid species in the world. It is the squid with the largest yield in the Japanese archipelago and also the squid with the largest economic value in the northern seas of my country. Yellow croaker, small yellow croaker and hairtail are collectively known as one of the four traditional fisheries in my country and are important fishing targets. However, since the 1980s, due to various reasons such as overfishing and the destruction o...
