Embodiment

[0015] In 2007, the seed production of spotted flounder was carried out at Qingdao Jinshatan Aquatic Development Co., Ltd. on March 4, March 11, March 18, March 25, April 1, and April 8. On April 15th, April 22nd, select male flounder broodstock weighing 0.7-1kg and able to squeeze out milky white semen. The water temperature is 7-11°C. / kg was induced by artificial feeding; induced once every 7 days, the number of inductions was 8 times, and a total of about 2.87 million fertilized eggs were obtained.

Abstract

The invention belongs to the marine biotechnology field, in particular to a method for prolonging the semen discharge period of Verasper moseri, thereby solving the problems of non-synchronous development of female and male Verasper moseri, and the like; the method prolongs the semen discharge period and obtains high-quality semen by inducing the male Verasper moseri broodstock by a hormone within a certain temperature range. The induction by HCG with the dose of 250-500IU / kg and the condition of 7-11 DEG C is carried out, thereby prolonging the semen discharge time of the male Verasper moseri broodstock, achieving the synchronous mature of the female and the male broodstock, improving the fertilization rate of artificial insemination and obtaining batch fertilized eggs. The method provides the technical guarantee for the industrial development of the Verasper moseri which is a valuable fish species.

Description

Technical field: [0001] The invention belongs to the technical field of marine organisms, in particular to a method for prolonging the ejaculation period of spotted flounder. Background technique: [0002] Spotted star flounder (Verasper moseri) is cultivated indoors, and the sexual maturity of the female and male broodstock is not synchronized; it is difficult for the spotted star flounder to spawn naturally indoors, and fertilized eggs are generally obtained through artificial insemination; male broodstock matures one year earlier than female broodstock. When the female reaches sexual maturity, the gonads of the male broodstock begin to degenerate, and the quality and quantity of semen required for artificial reproduction cannot be reached. For the above reasons, the improvement of the artificial propagation technology of the spotted flounder is seriously restricted. Invention content: [0003] The object of the present invention is to provide a method for prolonging th...
