Substitute bait for bay breeding scallops and preparation method thereof

Abstract

The invention discloses substitute bait for bay breeding scallops and a preparation method thereof, and belongs to the technical field of aquatic feed preparation. The bait comprises the following rawmaterials in parts by weight: 40-50 parts of spirulina powder, 20-30 parts of chlorella powder, 10-15 parts of soluble starch, 5-6 parts of dry yeast powder, 2-3 parts of marine red yeast powder, 2-3parts of egg yolk, 1-2 parts of schizochytrium powder and 0.002-0.005 part of chitosan oligosaccharide. The preparation method is as follows: subjecting the spirulina powder, the chlorella powder, the soluble starch, the dry yeast powder, the marine red yeast powder, the egg yolk, the schizochytrium powder and the chitosan oligosaccharide to primary crushing, mixing and uniform stirring; and carrying out micronization on the material obtained by the mixing and uniform stirring, and conducting sieving with a 100-mesh sieve to obtain the final product. The method adopts a healthy product formula, the bait does not generate drug resistance and toxic or side effect, no drug residue is left in the scallop body, and the bait can promote the development of gonad of parent scallops.

Description

technical field [0001] The invention belongs to the technical field of aquatic feed preparation, and in particular relates to a substitute bait for bay scallop species and a preparation method thereof. Background technique [0002] Bay scallops (Argopecten irradias) belong to the class Phalalobranches, Heterocylinda, Scallopidae, and the genus Scallop. Also known as the Atlantic bay scallop. The shell is medium-sized, nearly round. The surface of the shell is yellowish brown, with about 20 radial ribs, the ribs are wide and raised, and there are no spines on the ribs. Growth lines are more obvious. No foot silk. The top of the shell is located in the center of the dorsal side, the front shell ears are large, and the back shell ears are small. Native to the east coast of the United States. It was introduced into China by Zhang Fusui in 1982, and artificial breeding was carried out. The current annual output is about 80,000 tons, mainly concentrated in Shandong and Liao...

Problems solved by technology

[0003] Studies in the prior art have shown that the water temperature and accumulated temperature of bay scallops are related to the gonad index, and different accumulated temperatures have different effects on ovarian development. However, in addition to these breeding factors, the bait they feed has a greater impact, and the current research on bait is rare. to report
