激素缓释制剂诱导海水养殖鱼类性腺发育成熟与生殖行为的研究进展

Study advance on induction of gonadal development & maturation and reproductive performance by sustained hormone releasing delivery systems in marine fishes

综述促性腺素释放激素类似物 (GnRH a)缓释制剂 (SRDS)、人绒毛膜促性腺激素 (HCG)SRDS、类固醇激素SRDS :雄烯二酮 (ADSD)和 17α 甲基睾丸酮 (MT)以及鲤垂体匀浆 (CPE)混合SRDS诱导海水养殖鱼类性腺发育成熟和生殖行为的效果。认为采用GnRH aSRDS处理性腺发育良好的鲈形目鱼类和鲆鲽鱼类 ,可以显著提高血液促性腺激素 (GtH)水平 ,且持续时间长 ,诱导排卵成功 ;HCG乳胶SRDS可诱导日本鳗鲡 (Anguilajaponicus)血液GtH持续升高 ,性成熟系数明显升高并且性腺发育成熟 ;HCG和CPE水 /油 /水 (W /O/W )复乳SRDS对日本鳗鲡的催熟效果显著 。

Induced gonadal maturation and reproductive performance using sustained release delivery systems (SRDS) of gonadotropin releasing hormone analog (GnRH a) ,human chorionic gonadotropin(HCG), and rostenedione(ADSD) and 17a methyltestosterone(MT),multiple emulsion containing HCG and carp pituitary extraction(CPE) in marine fish are reviewed. GnRh a SRDS can induce a high serum gonadotropin ( GtH) levels and long duration in perciform fish and flounder at the final stages of gonadal development,subsequently,ovulating and spawning. Emulsion HCG SRDS can induce a high serum GtH level and long duration in Japanese eel (Anguila japonicus),and subsequently,the increase of gonadal somatic index(GSI) and the maturation of gonad. A significant induced gonad maturation can be obtained using multiple emulsion containing HCG and CPE SRDS (water/oil/water) in Japanese eel. ADSD and MT SRDS can also induce the gonadal maturation and ovulation in Japanese eel.
