Black rockfish phagostimulant

Abstract

The invention discloses a feeding promoting agent of sebastodes fuscescens, the ingredients and the weight percentage of which are: 35 to 45 percent of betaine, 25 to 35 percent of inosinicacidIMP, 15 to 20 percent of dimethyl-Beta-propiothetin, 8 to 15 percent of glycine and 5 to 10 percent of sodium citrate; the feeding promoting agent is prepared by that various raw materials used for preparing the feeding promoting agent are dried, grinded, weighed accurately according the dosage and mixed fully and evenly with the coefficient of variation being less than or equal to 5 percent; the feeding promoting agent of feedstuff is applied to the compound feedstuff of the sebastodes fuscescens by the proportion of 0.5 (weight percentage), and can promote the ingestion and the growth of the sebastodes fuscescens with 82.06 percent of the rate of body weight gain, 1.29 percent of specific growth rate and 2.81 percent of ingestion rate; meanwhile, the used raw materials have stable source, low price, simple manufacturing technique and little waste feedingstuff, reduce remnant feed, is beneficial to environmental protection and can carry out the production and the aquaculture of the sebastodes fuscescens on large scale.

Description

Technical field: [0001] The invention belongs to an additive for compound feed of seawater fish, and is a feed attractant formula for promoting the feeding and growth of black oysters under the conditions of breeding and production. Background technique: [0002] In recent years, with the rapid development of the aquaculture industry and the formation of large-scale and intensive production of artificial breeding of various aquatic animals such as fish, shrimp, and crabs, the application and research of aquatic feed attractants in the feed industry and aquaculture industry Has been developed by leaps and bounds. [0003] Black minnow (Sebastes schlegeli) is an important fish breeding object in the northern coast of my country. At present, it is mainly fed with small miscellaneous fish. It takes time and effort to feed bait, which not only aggravates the damage to offshore resources and pollutes the sea area environment, but also easily causes fish farming A variety of nutrit...

Problems solved by technology

[0003] Black minnow (Sebastes schlegeli) is an important fish breeding object in the northern coast of my country. At present, it is mainly fed with small miscellaneous fish. It takes time and effort to feed bait, which not only aggravates the damage to offshore resources and pollutes the sea area environment, but also easily causes fish farming A variety of nutritional deficiencies, reducing the survival rate of breeding

Using artificial compound feed to replace small miscellaneous fish can solve the above problems, but in the process of use, it is found that the black fish is not active in eating the compound feed, which aff
