Problems solved by technology

The squids lay eggs collectively, sticking together on the same egg chain to form a common grape-shaped spawning area, with an average egg production of 354. At the same time, similar to the squid without needles, the squid has no obvious protection. Egg behavior, coupled with overfishing of juvenile squid, overwintering squid, and spawning broodstock during the breeding season, has resulted in a serious threat to the supplementary population of the squid resource, resulting in resource decline

Embodiment 1

[0019] A method for cultivating squid seedlings, comprising the selection and matching of broodstock, broodstock cultivation, artificial propagation, seedling cultivation, and its specific steps are:

[0020] 1) Selection and grouping of parents: according to the natural breeding method of squid, healthy, sexually mature male and female squid were selected as parents, and then the male and female squid were paired at a ratio of 4:1;

[0021] 2) Parental cultivation: Temporarily raise the grouped squid in an indoor cultivation pool, control the water temperature at 20°C, seawater salinity at 30, and photoperiod L:D at 4:18, and stimulate them with running water. The flow rate is 8m / min, and the time is 10min. The bait containing fermented soybean meal is fed 4 times a day, and the total feeding amount is 0.3 times the weight of the parent body. Fermented by Lactobacillus sugar;

[0022]3) Artificial reproduction: collect the fertilized eggs with the attached egg base in the cu...

Embodiment 2

[0030] A method for cultivating squid seedlings, comprising the selection and matching of broodstock, broodstock cultivation, artificial propagation, seedling cultivation, and its specific steps are:

[0031] 1) Selection and grouping of parents: according to the natural breeding method of squid, healthy, sexually mature male and female squid were selected as parents, and then the male and female squid were paired at a ratio of 3:1;

[0032] 2) Parental cultivation: Temporarily raise the grouped squid in an indoor cultivation pool, control the water temperature at 24°C, the seawater salinity at 27, and the photoperiod L:D at 4:20, and stimulate them with running water. The flow rate is 6m / min, and the time is 12min. The bait containing fermented soybean meal is fed 3 times a day, and the total feeding amount is 0.5 times the weight of the parent body. Fermented by Lactobacillus sugar;

[0033] 3) Artificial reproduction: collect the fertilized eggs by using the attached egg b...

Embodiment 3

[0041] A method for cultivating squid seedlings, comprising the selection and matching of broodstock, broodstock cultivation, artificial propagation, seedling cultivation, and its specific steps are:

[0042] 1) Selection and grouping of broodstock: According to the natural breeding method of squid, healthy, sexually mature male and female squid are selected as parents, and then the male and female squid are paired at a ratio of 2:1;

[0043] 2) Parental cultivation: Temporarily raise the grouped squid in an indoor cultivation pool, control the water temperature to 25°C, the seawater salinity to 25, and the photoperiod L:D to 4:25, and carry out running water stimulation. The flow rate is 5m / min, the time is 15min, and the bait containing fermented soybean meal is fed twice a day. The total feeding amount is 0.6 times the weight of the parent body. Fermented by Lactobacillus sugar;

[0044] 3) Artificial reproduction: collect the fertilized eggs with the attached egg base in ...

Abstract

The invention discloses a culture method of young sepia lycidas. The culture method comprises the steps of selection and mating of parents, culture of the parents, artificial propagation and culture of young sepia lycidas, and comprises the specific steps that mated sepia lycidas is temporarily reared in an indoor culture pond for stimulation by running water, bait containing fermented soybean meal is cast, and the fermented soybean meal is obtained by fermenting lactobacillus rhamnosus containing tocopherol and cysteine; after a sepia lycidas parent lays eggs naturally, fertilized eggs are collected, after a disinfectant is sprayed, artificial hatching is carried out, then hatched young sepia lycidas is cultured in a young sepia lycidas pond, fresh bait is cast, and after culture of youngsepia lycidas is completed, young sepia lycidas with water is sold. The culture method of young sepia lycidas has the advantages that the hatching rate is high, the survival rate is high, the diseases are few, the young sepia lycidas culture quantity is high, breeding is easy, the growth is quick, the specification of a finished product is large, the implementation and operation are easy, the success rate is high, and the culture method is suitable for large-scale promotion.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating squid seedlings. Background technique [0002] Squid belongs to the phylum Molluscs, Cephalopoda, Tenbrachia, Sepia, and is one of the species with the most development potential of cephalopods. Its meat is delicious, and the edible part accounts for more than 90%; its gonads can be processed into "squid". Fish ears" and "mullet eggs"; in addition, its cuttlefish and ink sacs have blood coagulation, anti-tumor, and anti-cancer effects. Therefore, squid is deeply loved by the public and is an important marine fishery resource in my country. In recent years, there have been more in-depth studies on the distribution of squid resources at home and abroad. At present, there are mainly species that are caught, developed and utilized. In my country, the output of golden squid, squid, squid, squid, and tiger squid is relatively high. . However, due to overf...
