Problems solved by technology

The natural squid preys on fish and crustaceans as natural feed. At present, the artificial cultured squid mainly uses frozen small fish as feed, and the frozen small fish are directly or chopped up and then scattered. In the aquaculture water body, the daily feeding amount is 8-20% of the total weight of squid mansoni, generally 1-3 times a day, and the utilization rate of squid mansoni to ...

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the examples.

[0015] Mann-style needle-free squid feeding method, including parental temporary feeding and seedling cultivation feeding,

[0016] 1) Temporary feeding by parents

[0017] Temporarily raise the assembled Mann-style needleless squid in an indoor cement pool. Squid was stimulated by running water at 5-8m / min for 10-15 minutes, and the feeding amount of Artemia larvae, vitamins, mysis, and minerals was 0.15-0.25 times the weight of the parent every hour during the holding period. Artemia larvae, Vitamins, mysis, minerals by weight 45:5:45:5; minerals include the following components: MgSO 4 ·7H 2 O, FeSO 4 ·7H 2 O, MnSO 4 ·H 2 O, ZnSO 4 ·H 2 O, CoCl 2 ·6H 2 O, Na 2 SeO 3 , CuSO 4 ·5H 2 O, zeolite powder, KI, its percentage by weight is: 80:5:5:3:3:2:1:0.95:0.05;

[0018] 2) Seedling cultivation and feeding

[0019] Feeds are fed within 24 hours after the seedlings ...

Abstract

The invention belongs to the technical field of sea culture and particularly relates to a method for feeding sepiella maindroni. The method comprises steps of parent temporary culture feeding and seedling culture feeding. The parent temporary culture feeding comprises steps of temporarily culturing matched sepiella maindroni in an indoor cement pool and feeding the sepiella maindroni by using artemia larvae, vitamin, shrimps and minerals alternately at one-hour intervals in the temporary culture period. The seedling culture feeding comprises steps of feeding feed within 24 hours from seedling hatching, wherein the feed consists of raw materials such as basic materials, white fish meal, microcrystalline cellulose, dextrin, biological extract oil, the artemia larvae, the shrimps and flavones, and feeding pulpy feed to net boxes used for culturing the sepiella maindroni at five-time intervals each day. By the aid of the method, reasonable nutrition requirements of the sepiella maindroni can be met, the good intake effect is achieved, the feed cannot be accumulated excessively in the water, the sepiella maindroni can grow quickly and the survival rate of the sepiella maindroni is high and can reach more than 43%.

Description

technical field [0001] The invention belongs to the technical field of mariculture, and in particular relates to a Mann-style needleless squid feeding method. Background technique [0002] Sepiella maindroni belongs to cephalopods and is an important marine economic animal in my country. It is rich in protein and unsaturated fatty acids, etc., and the crude protein content is 79.74% of the ash weight. Amino acids and 4 kinds of umami amino acids, EPA and DHA are the main unsaturated fatty acids, so the squid is rich in nutrition and delicious, and is deeply loved by the public. The natural squid preys on fish and crustaceans as natural feed. At present, the artificial cultured squid mainly uses frozen small fish as feed, and the frozen small fish are directly or chopped up and then scattered. In the aquaculture water body, the daily feeding amount is 8-20% of the total weight of squid mansoni, generally 1-3 times a day, and the utilization rate of squid mansoni to frozen sma...
