| 摘 要： | 研究了不同盐度海水驯养中史氏鲟血清激素催乳素、皮质醇、胰岛素样生长因子-Ⅰ、四碘甲状腺原氨酸和三碘甲状腺原氨酸的变化规律及其对渗透压的调控作用.随着海水盐度逐渐升高,史氏鲟催乳素含量随之下降.从淡水刚进入海水中时史氏鲟的皮质醇含量下降,在进入盐度为25的海水中皮质醇含量上升.驯养过程中胰岛素样生长因子-Ⅰ的含量变化较小,四碘甲状腺原氨酸和三碘甲状腺原氨酸的含量在进入海水中后有所升高.这5种激素协同作用,共同增强史氏鲟对海水的适应性和渗透压调节能力,其中催乳素和皮质醇对渗透压调控起主要作用.史氏鲟经海水驯养后进行海水养殖是可行的.

| Abstract: | Changes of hormonal levels during seawater acclimation in Amur sturgeon (Acipenser schrenckii) were studied.Serum prolactin levels decreased continuously with the growing salinity.Serum cortisol levels in Amur sturgeon decreased after transfer from fresh water into seawater in the beginning.Serum cortisol levels in Amur sturgeon increased after transfer into 25 salinity.Serum insulin-like growth factors-I levels changed slightly during seawater acclimation.Serum thyroxine and triiodothyronine in Amur sturgeon increased slightly.Therefore these hormones acted together to promote seawater adaptation in Amur sturgeon.However,prolactin and cortisol were most important.It was feasible to culture Amur sturgeon in seawater after seawater acclimation. |
