Embodiment 1

[0045] A. Parental domestication and intensive cultivation:

[0046] The broodstock are individuals cultivated in factory overwintering or wild broodstock caught in the coastal waters of Fujian and Guangdong from the beginning of May to the end of August every year. The parent body has normal color, strong activity, active food intake, weight over 700g, and the breeding density is 3-5 birds / m 3 In the water body, the male to female ratio is 1:1-1:1.5, the water temperature is 20-26°C, the salinity is 28-32, the pH is 7.8-8.2, the dissolved oxygen is kept above 5mg / L, and the light intensity is 400lx-800lx. Adopt flowing water to cultivate, and the water exchange volume is 400%-700%. The bait is live fish and live shrimp, and the daily feeding amount is 2%-3% of the squid's body weight. It is fed twice a day, and the feces, residual bait and dead individuals are cleaned up every morning, and the water is changed thoroughly.

[0047] B. Collection of fertilized eggs:

[0048]...

Embodiment 2

[0059] The difference with embodiment one is that the attachment base adopts sycamore branches, and other conditions are the same, and the average daily egg production is about 5-7kg.

Embodiment 3

[0061] The difference with Embodiment 1 is that the attachment base adopts the dendritic attachment base made of plastics, and other conditions are the same, and the average daily egg production is about 3-5kg.

Abstract

The invention relates to a sepioteuthis lessoniana fry culture method, and belongs to the technical field of aquaculture. The sepioteuthis lessoniana fry culture method is characterized by comprisingthe following steps of 1, parent domestication and strengthening culture; 2, fertilized egg collection; 3, fertilized egg hatching; 4, fry culture. According to the hatching method, the problems thata large number of oothecae are stuck together, the permeability is poor, the hatching temperature is high, the hatching time is long, and the oothecae are likely to be infected by bacteria to rot aresolved.

Description

technical field [0001] The invention relates to a method for cultivating pseudo squid seedlings, belonging to the technical field of aquaculture. Background technique [0002] Sepioteuthis lessoniana Lesson belongs to molluscs, cephalopods, sheath subclasses, guniformes, closed eyes, squid family, pseudo squid genus, is a large squid, mainly distributed in It is also distributed in the southern part of Fujian and the coastal areas of Guangdong, the Japanese archipelago, the Hawaiian archipelago, the Malay archipelago, the Indian offshore, and the Red Sea. The squid is a major economic cephalopod in the warm water area of ​​the western Pacific Ocean. It is often caught in the coastal waters of Guangdong and southern Fujian in China. The annual output is about 200 tons. The edible part is relatively high, the meat is tender and delicious, and it is a good seafood after drying. It has extremely high edible, nutritional, medicinal and economic values, and is deeply loved by cons...
