Formula and processing technology for preparing soft particle baits of scylla serrata

Abstract

The invention discloses a formula and a processing technology characterized by adding poached shellfish juice concentrated liquor as an attractant of soft particle baits of scylla serrata. The formula comprises the following components by weight percent: 25% of fish powder, 12% of cooked peanut cake powder, 12% of cooked soybean meal, 10% of wheat middling, 15% of glutinous rice, 15% of chilled fresh offal fish, 5.5% of shrimp and crab shell powder, 0.4% of fish oil, 0.09% of shelling element, 0.01% of phospholipid and 5% of shellfish juice concentrated liquor. The formula and the processing technology have the advantages that the shellfish juice concentrated liquor is prepared by concentrating waste cooking liquor obtained after poaching shellfish in the processing enterprises of canned shellfish or shellfish dried products and is added to the synthetic formula as the food attractant of artificial mixed baits of scylla serrata, thus greatly improving the palatability of the artificial mixed baits of the scylla serrata and increasing the nutritional components of the baits; by utilizing the characteristics of strong adhesion between high-viscosity rice and feeds of fresh and live fish and good stability, the soybean meal is uniformly polymerized in the dextrin molecules of glutinous rice to form a stable bonding state; the baits have high digestive performances and good palatability.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a formula for making soft granular bait for mud crabs and a processing technology thereof. Background technique [0002] Scylla is mainly carnivorous bait, and has the characteristics of being picky about food. It likes to eat shellfish and small crustaceans, as well as small miscellaneous fish, small shrimps and crabs, and anorexias plant bait. In recent years, the breeding area of ​​blue crabs in coastal areas has been continuously expanding, and the demand for animal bait is also increasing. The bait of blue crabs has always been low-value shellfish collected on the sea flat and small fish and shrimps caught in the ocean. With the development of coastal industries, a large amount of tidal flat resources have been occupied, and feeding crabs with low-value shellfish has become a history. Small miscellaneous fish caught in the sea have become the main source of feed for bl...

AI Technical Summary

Problems solved by technology

Small miscellaneous fish caught in the sea have become the main source of feed for blue crab farming. However, with the decline of marine resources and the emergence of summer fishing moratorium, fresh and live bait cannot meet the needs of blue crab breeding, and feeding fresh and live bait also causes The pollution of water quality in the breeding pond affects the healthy growth of blue crabs, easily causes the disease and death of blue crabs, brings great economic losses, and restricts the development of blue crab breeding industry to a certain extent
