Phagostimulant specially for river crab and its prepn process

Abstract

The phagostimulant specially for river crab and its preparation process belongs to the field of aquatic animal additive technology. The phagostimulant consists of methionine, leucine, arginine, glycine, tyrosine, garlicin, rhubarb, asafetida and freeze dried powder of enzymolyzed animal insides. Adding the phagostimulant in 0.3-2 wt% into feed for river crab can increase the ingested amount of river crab, promote its growth, and reduce feed waste and water pollution. The preparation process of the phagostimulant includes mixing the said ingredients in certain weight proportion and stirring in a stirrer.

Description

technical field [0001] The invention relates to a special attractant for river crabs and a preparation method thereof, belonging to the technical field of aquatic animal additives and preparation methods thereof. Background technique [0002] River crabs have mixed feeding habits and prefer animal foods, such as fish, shrimp, snails, worms, insects and their larvae. Sometimes they also attack frogs and tadpoles, and cannibalize their own species. They are more interested in animal corpses. But in general, plant foods are easier to get than animal foods. The stomachs of river crabs are often dominated by plant foods, such as aquatic vascular bundles or some shore plants, such as Hydrilla verticillium, Esserectia balsamicus, Algae chinensis, and eye vegetables. Even some crops can be eaten by river crabs. Under artificial breeding conditions, river crabs have a wider diet and often feed on shellfish, snails, frozen small fish, bean cakes, wheat flour, and ...
