摘要(Abstract)：

用4种不同浓度的甲状腺素(T4)分别浸泡斜带石斑鱼卵黄囊期仔鱼,研究T4对仔鱼发育、生长和存活的影响。结果表明,在孵化后24 h内,T4对仔鱼发育的促进作用不明显;在孵化24 h后,T4对仔鱼消化道的发育有促进作用。在孵化后72 h,0.01 mg·L-1 T4处理组仔鱼小肠管径、直肠管径、全长与对照组相比差异均不明显;0.10 mg·L-1和1.00 mg·L-1 T4处理组仔鱼小肠和直肠管径显著比对照组大(P<0.01),1.00 mg·L-1 T4处理组仔鱼全长显著比对照组短(P<0.01),而0.10 mg·L-1处理组仔鱼全长与对照组相比无明显差异(P>0.05)。在孵化后第8天,0.10 mg·L-1 T4处理组仔鱼存活率明显比对照组高(P<0.01),而0.01 mg·L-1 T4组和1.00 mg·L-1 T4组与对照组之间存活率差异不明显(P>0.05)。结果提示0.10 mg·L-1 T4处理能促进斜带石斑鱼卵黄囊期仔鱼的消化道发育并提高其存活率。
