Abstract
The invention discloses transsexual feed for cynoglossus robustus and a preparation method of the transsexual feed. The feed is prepared from the following components in percentage by mass: 20-60% offish meal, 10-30% of protein hydrolysate, 3-10% of beer yeast, 10-30% of wet artemia, 5-10% of shrimp flesh, 5-10% of egg powder, 15-30% of flour, 1-5% of fish oil, 1-3% of phospholipid, 1-3% of glycine betaine, 1-2% of a vitamin mixture, 2-4% of a mineral element mixture, 1-5% of a microbial preparation, 1-3% of a compound immunopotentiator, 1-5% of copepod, 1-3% of casein and 1-2% of a phagostimulant. The transsexual feed for cynoglossus robustus disclosed by the invention can achieve the effects of promoting the development of sexual glands, promoting male-to-female transformation of the cynoglossus robustus, regulating the sex ratio of the cynoglossus robustus cultured population, reducing the ratio of male cynoglossus robustus in the cultured population, increasing the ratio of femalecynoglossus robustus, improving the survival rate, improving the feed conversion ratio and specific growth rate, obviously increasing the aquaculture field of the cynoglossus robustus and reducing the culturing cost and has significances for promoting cynoglossus robustus fries and developing the breeding industry of the cynoglossus robustus.
Description
technical field [0001] The invention belongs to the technical field of aquaculture. More specifically, it relates to a sex-transforming (male-to-female) feed for tongue sole and a preparation method thereof. Background technique [0002] Tongue sole (Cynoglossus robustus (Günther, 1873)) is a fish species of Cynoglossus robustus in the family Cynoglossidae. Tongue sole is one of the rare economic fish in the ocean. It contains 13.7 grams of protein and 1.2 grams of fat per 100 grams. Braised tongue sole in soy sauce is one of the famous dishes, which can be processed into salty and dried products besides fresh food. [0003] For the culture of tongue sole, due to the slow growth and high proportion of male individuals, it affects the quality of commercial fish, reduces the breeding output of tongue sole, increases the cost of breeding, affects the promotion of tongue sole seedlings, and limits the development of tongue sole breeding industry . [0004] Therefore, it is o...
