Method for feeding sepiella maindroni

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...

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 small miscellaneous fish is relatively low. low, and will cause water pollution, so the survival rate of artificially cultured mansoni squid with frozen small miscellaneous fish as feed is low, less than 35%, and the feed cost is higher, thereby reducing the artificial culture of mansoni. The benefit of the needle squid also restricts the scale of the artificial culture of the needle squid
