Embodiment

[0027] Example: refer to Figure 1 to Figure 7 , the method for cultivating artificial seedlings of squid with flowing water, including the temporary raising of the parent body, the collection of ovum, the hatching of ovum, and the cultivation of larvae in four steps, wherein

[0028] Temporary breeding of broodstock: Selectively mature broodstock squid are put into the pool, temperature, salinity, stocking density are controlled, water quality is maintained, and fresh and live small fish and shrimp are fed for temporary breeding;

[0029] Egg collection: Put the pregnant egg broods into the spawning pool at a ratio of 1:1 to 5:1, and collect fertilized eggs regularly;

[0030] Egg hatching: gather the eggs of the same batch into the breeding pool 5 of the artificial seed cultivation device of the squid flowing water type for hatching; the water temperature is 22-35°C, and the seawater salinity is 26‰-33‰;

[0031] Cultivation of larvae: The first feeding starts 6-12 hours af...

Abstract

The invention discloses a running water type artificial seed cultivation method for sepia lycidas gray. The running water type artificial seed cultivation method includes steps of temporarily cultivating parents; collecting eggs; enabling the eggs to hatch; cultivating young sepia lycidas gray. The running water type artificial seed cultivation method has the advantages of low water changing frequency, running cost and manufacturing cost, good water treatment effect and disease control effect, high stability and seed yield, demand-based controllable ammonia nitrogen treatment scale and environmental friendliness.

Description

technical field [0001] The invention relates to a method for cultivating aquatic seedlings in a continuous factory, in particular to a method for cultivating artificial seedlings of squid with flowing water. Background technique [0002] In recent years, my country's aquaculture industry has developed rapidly, and the traditional extensive farming methods can no longer meet the needs of aquaculture development. It is an inevitable trend to replace the traditional extensive aquaculture method with the advantages of water saving, environmental protection, controllable water quality, and production not affected by climatic conditions by adopting the industrialized recirculating aquaculture system. At present, in the production of aquatic seedlings, the method of raising seedlings in large water bodies and concentrated water is mainly used. This method mainly uses artificial synthetic bait to feed seedling larvae, which is easy to pollute the water quality and cause the seedling...
