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

Embodiment 1

[0012] Embodiment 1, a formula for making the soft granular bait of mud crabs, including fish paste, fried rice, and mixed dry ingredients. The weight parts of mixed dry ingredients, fish paste, and fried rice are: 50 parts of mixed dry ingredients, fish paste 30 parts, 20 parts of fried rice; the weight ratio of each component of the mixed dry material is: fish meal 45%, cooked peanut cake powder 15%, cooked soybean meal powder 15%, secondary powder 20%, shrimp and crab shell powder 4.5% %, fish oil 0.4%, shellin 0.09%, phospholipid 0.01%. The fish paste is prepared by stirring and mixing fresh frozen low-value fish with the shellfish juice concentrate, and the solid-to-liquid ratio of the fish paste is 1:2-3; It is prepared by steaming in a steamer and ventilating and cooling. Glutinous glutinous rice (cooked high-viscosity rice) and fresh fish feed have strong adhesion and good stability. The soybean meal powder is evenly aggregated in the dextrin molecules of the sticky r...

Abstract

The invention discloses a formula for preparing a soft pellet bait for scylla serrata. According to the formula, the bait comprises the following components in parts by weight: 40 to 50 parts of mixed dry material, 20 to 30 parts of fish mince, and 20 to 30 parts of glutinous rice; the mixed dry material comprises the following components in percentage by weight: 40 to 50% of fish meal, 10 to 20% of cooked groundnut meal, 10 to 20% of cooked soya bean meal, 10 to 20% of wheat middling, 4.5% of shrimp and crab shell powder, 0.4% of fish oil, 0.09% of decorticating agent, and 0.01% of phospholipid. According to the formula for preparing the soft scylla serrata pellet feed, waste soup which is produced by cooking shellfish of a canned shellfish or dried shellfish product processing enterprise is concentrated to obtain shell concentrated liquor which is added to a synthetic formula as a food attractant of synthetic scylla serrata bait, and therefore, the palatability of the synthetic scylla serrata bait and the nutritional ingredients of the bait are greatly improved and increased.

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. 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 blue crab farming. However, with the d...
