Artificial particle feed for juvenile turbot

Abstract

The invention relates to an artificial particle feed for juvenile turbot. The artificial particle feed is characterized by being prepared from whitefish powder, euphausiid powder, scallop powder, beer yeast, starch, cod liver oil, yolk powder, whey powder, L-alanyl-L-glutamine, choline chloride, soybean lecithin, schizochytrium limacinum powder, haematococcus pluvialis powder, compound vitamins, compound mineral substances, Chinese herbal medicines and sodium alginate. As the various raw materials are added into the feed, the comprehensiveness of nutrition is guaranteed. An immunopotentiator is added into the feed, so that the non-specificity immunity of fish bodies is enhanced. The feed is green and pollution-free. The schizochytrium limacinum powder and the haematococcus pluvialis powder are added into the feed, and the content of vitamin E is improved, so that the whitening rate of the juvenile fish is effectively reduced. The Chinese herbal medicine components are added, so that the immunity of the juvenile fish can be improved and parasite diseases in a juvenile fish growing phase are prevented from happening.

Description

technical field [0001] The invention belongs to the technical field of fish feed, in particular to an artificial granular feed for juvenile turbot. Background technique [0002] Turbot belongs to the flounder family and the genus Turbot. It is a rare flatfish native to the North Sea, the Baltic Sea and the Mediterranean coast of Europe. my country has introduced and domesticated it since 1992. The fish grows fast, has delicious meat, and has high nutritional value. The market It has broad prospects and has become the main breeding species in the northern coastal areas. [0003] At present, juvenile turbot is mainly fed fresh trash fish, but there are several problems in feeding fresh trash fish. Feeding fresh miscellaneous fish is likely to cause pollution of the aquaculture water body, and the conversion rate is low, and the actual aquaculture cost is very high. More importantly, long-term large quantities of fresh miscellaneous fish as the bait source for turbot farming w...

AI Technical Summary

Problems solved by technology

[0004] Although feeds for juvenile turbot have appeared on the market, most of the low-quality feeds have problems of nutritional imbalance, while imported high-quality feeds are too expensive and cost-effective, and farmers have low breeding benefits

In addition, in the breeding process of juvenile turbot, parasitic diseases such as shield ciliates occur frequently, the incidence of lymphocystosis is high, and the albinism rate is high at the same time, all of which seriously affect the breeding of juvenile turbot The survival rate at this stage also brings risks to the subsequent breeding of adult fish, and the occurrence of lymphocystosis and albinism will affect the appearance of farmed adult fish and reduce the commodity value
