Compound feed for early growth stage of epia lycidas

Abstract

The invention discloses a compound feed for an early growth stage of epia lycidas. The compound feed is prepared from the following raw material components by weight: 42.0kg of white fish meal, 22.0kg of bean pulp, 5.0kg of krill meal, 5.4kg of dextrin, 12.0kg of alpha-starch, 4.1kg of fish oil, 2.0kg of soya bean lecithin, 5.0 kg of gelatin, 0.5kg of choline chloride, 0.5 kg of monocalcium phosphate, 1.0 kg of composite vitamin and 0.5 kg of composite minerals. The compound feed can be used for solving the problems that a special compound feed is not provided for artificially breeding the epia lycidas at present, especially, the breeding cost is high, the parva and the like are mostly settled as opossum shrimps, parva and frozen small trashes are needed to feed at the early growth stage of epia lycidas, and the pollution degree to water is high, so that the survival rate which can be over 67% of the epia lycidas is increased.

Description

technical field [0001] The invention relates to a feed for raising squid, in particular to a compound feed for the growth stage of the squid. Background technique [0002] Squid ( Sepia lycidas ), taxonomically belongs to Mollusca, Cephalopoda, Sepioidea, Sepiidae, Sepia ( Sepia ), Mesomorpha squid has the characteristics of short life cycle, large individual (up to 4 kg or more), fast growth (up to 500 g after 4 months of breeding), and high nutritional value, and has become a species that attracts attention in mariculture. The breeding period of the squid is divided into the early growth period (30~60 days old, carcass length 2cm~6cm, body weight 2.2g~15.0g), middle growth stage (60~90 days old, carcass length 6cm~10cm, body weight 15.0g~120g ), late growth period (90-150 days old, carcass length, 10cm-18cm, weight 120g-750g). At present, the research on squid is mainly focused on reproductive behavior, the influence of environmental factors on its growth, feeding and ...

AI Technical Summary

Problems solved by technology

At present, the research on squid is mainly focused on reproductive behavior, the influence of environmental factors on its growth, feeding and embryonic development, as well as artificial breeding techniques. There is no report on the compound feed specially used for breeding squid.

Although the compound feed of other squids is disclosed, as the patent application for invention with publication number CN102960571, the compound feed of golden squid is disclosed, and the components in the feed are: fish meal, shrimp meal, soybean meal, seaweed powder, yeast, starch, fish oil, Choline chloride, biological enzymes, lecithin, multivitamins and multiminerals; the invention patent with the authorized announcement number CN102919614 discloses a compound feed for golden squid seedlings. The ingredients in the feed include: white fish meal, shrimp head powder, fermented soybean meal, sargassum powder, starch, protein powder, choline chloride, wood bran polysaccharide, calcium dihydrogen phosphate, and multivitamins; but it is not very suitable for the growth of squid, especially the growth of squid seedlings. Therefore, at present, most of the squid are cultured with natural feed such as mysis, shrimp, and small fish. The breeding cost is high and it is easy to cause environmental pollution. It is necessary to develop a compound feed for the growth of squid seedlings to save costs and reduce environmental pollution.
