Abstract

The invention relates to a combined feeding method of bait for squid seed domestication. In the method, formula I bait is fed 10-20 days after hatching of squid juveniles, formula II bait is fed 20-30 days after hatching, and formula II bait is fed 30 days after hatching. Days later, formula III bait was fed until the seedlings were sold. The method of the invention adopts bait cascade training, and performs bait transformation and domestication through the bait formula I, so that the young crow can adapt to the chilled bait, and the young crow can smoothly eat the bait formulas II and III, laying a solid foundation for the successful cultivation of the young crow in ponds. The raw material composition of the invention is scientific, the composition is reasonable, the source of the raw material is stable, it has the effect of attracting food for the young crow, can improve the anti-stress ability of the young crow, and is helpful for the recovery of the young crow after inkjet. In the method of the present invention, the bait raw materials for domestication of cuttlefish seedlings have scientific composition, reasonable composition matching, stable source of raw materials, simple production process, convenient breeding and use, and do not contain any dangerous drugs, thereby reducing the dependence of young squid on antibiotics, less investment, The bait pay is high.

Description

technical field [0001] The invention relates to a breeding method, in particular to a combined feeding method of baits for domesticating squid seedlings. Background technique [0002] With the improvement of people's living standards, people's demand for seafood is increasing, which drives the rapid development of mariculture industry, and the degree of intensification is getting higher and higher. Squid meat is delicious and nutritious. It is a very popular aquatic product, and it is also an important foreign exchange earning species for export. In recent years, industrial cultivation of squid seed has begun to be carried out in coastal provinces such as Hebei, Shandong, Jiangsu, Zhejiang, Fujian, Guangdong and Hainan, providing sufficient seed for squid release and artificial breeding. During the factory cultivation of seedlings, basically mysis and squids are used as bait. However, these baits are seriously affected by seasons and weather, resulting in insufficient supp...
