Problems solved by technology

[0002] At present, in the artificial breeding of flounder and flounder, the light conditions and temperature of broodstock breeding are generally simply adjusted to promote the gonad development of the broodstock, but this method often leads to dysplasia of the broodstock gonads, low gonad maturation rate, and low gonad index

Embodiment Construction

[0006] The method for regulating gonad maturation of star flounder and stone flounder with slow-release hormones of the present invention is characterized in that slow-release hormones for cold-water fish are embedded in artificially cultivated star flounder and stone flounder broodstock; The sustained-release hormone for fish contains water, gelatin, dioconone maleate and salmon gonadotropin-releasing hormone analogue (SGnRH-A), and their weight in grams is 100, 5, 1 and 0.02, respectively. Dosage: 1ml of slow-release hormone per kilogram of body weight for female broodstock, 0.2ml per kilogram of body weight for male broodstock. During operation, put the release hormone in warm water of 50-80°C, and the product can be dissolved into a liquid, keep the dissolved liquid in warm water of 25-30°C, and inject the slow-release hormone into the peritoneal cavity of the parent fish with an injection needle. Time of use: Inject when the gonads of the female broodstock develop to the ...

Abstract

A method for controlling the maturation of sex gland of verasper and kareius features that a slow-releasing hormone for cold-water fish, which contains water, gelatin, gonad stimulating hormone or ganodotropic releasing hormone or luteinizing hormone, etc. is embedded in the artificially cultured parents of verasper and kareius.

Description

technical field [0001] The invention relates to a method for regulating gonad maturation of star flounder and stone flounder by using slow-release hormone. Background technique [0002] At present, in the artificial breeding of flounder and flounder, the light conditions and temperature of broodstock breeding are generally simply adjusted to promote the gonad development of the broodstock, but this method often leads to dysplasia of the broodstock gonads, low gonad maturation rate, and low gonad index. Contents of the invention [0003] The object of the present invention is to provide a method for regulating gonad maturation of star flounder and stone flounder with slow-release hormone, which can overcome the above-mentioned shortcomings of the prior art. [0004] A method for regulating gonad maturation of star flounder and stone flounder with slow-release hormone, characterized in that slow-release hormone for cold-water fish is embedded in artificially cultivated star ...
