Feed for culturing sepia esculenta larvae

Abstract

The invention claims a feed for culturing sepia esculenta larvae, and belongs to the technical field of aquaculture. The sepia esculenta larvae breeding feed comprises following components according to the weight percentage: 25 to 35 parts of white fish meal, 12 to 20 parts of pomfret meal, 8 to 16 parts of gulfweed meal, 10 to 25 parts of shrimp head meal, 20 to 30 parts of fermented soybean meal, 20 to 30 parts of plant starch, 2 to 8 parts of hyperglobulinemia meal, 2 to 8 parts of rice bran polysaccharide, 5 to 10 parts of calcium dihydrogen phosphate, 5 to 15 parts of choline, 1 to 5 parts of complex vitamin and 0.01 to 0.5 part of fucoidan. The feed provided by the invention has advantages of reasonable formula, comprehensive nutrition, good palatability, good stability in water, mass production and convenience in storage, transportation and feeding, thereby being suitable for industrial production of the sepia esculenta larvae. In addition, the growth rate and the survival rate of the sepia esculenta larvae are improved by adopting the feed. Therefore, the feed is suitable for large-scale popularization.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, in particular to a breeding feed for golden squid seedlings. Background technique [0002] Gold squid belongs to the phylum Molluscs, Cephalopoda, Coleoptera, Sepia, Sepia, Squid, commonly known as mullet, cuttlefish, squid, needle cuttlefish, widely distributed in the Russian Far East Sea waters, Japan's Honshu, Shikoku, Kyushu Sea areas, the west coast and south coast of North Korea, the Bohai Sea, the Yellow Sea, the East China Sea, the South China Sea and other waters. The golden squid has delicious meat, high protein content, and a wide range of comprehensive utilization. It is an excellent variety with high economic value. At present, the artificial breeding of golden squid mainly uses frozen small trash fish as feed. Frozen small trash fish is not only expensive, inconvenient to store and transport, but also has a series of problems such as incomplete nutrition, poor palatability, and...

AI Technical Summary

Problems solved by technology

At present, artificially cultured golden squid mainly uses frozen small miscellaneous fish as feed, but frozen small miscellaneous fish not only has high cost, is inconvenient to store and transport, but also has a series of problems such as incomplete nutrition, poor palatability, and low absorption and utilization rate. Affected the survival rate of golden squid, restricted the further development of its breeding industry
