| 摘 要： | 研究用3种不同质量浓度梯度(分别为T0组:0 mg/L;T4组:400 mg/L;T8组:800 mg/L)牛磺酸强化的轮虫(Brachionus plica tilis)对3~20日龄的眼斑拟石首鱼(Sciaenops ocella tus)仔鱼的投喂效果.结果表明,T8组的仔鱼平均全长((8.5±0.8)mm)和成活率(70.5%)都明显高于T0组(平均全长:(6.3±1.0)mm;成活率:28.4%)和T4组(平均全长:(7.0±0.8)mm;成活率:27.4%),T0组和T4组之间生长和成活率并无显著差异;T8组仔鱼的耐干露及耐高盐度(65)能力明显比T0组和T4组强,即仔鱼的抗应激能力受轮虫强化剂牛磺酸的质量浓度影响显著(P<0.05).

| Abstract: | A feeding trail was conducted to investigate the effect of rotifers enriched with different levels of taurine(T_0:0 mg/L;T_4:400 mg/L;T_8:800 mg/L) on the growth and survival as well as stress resistance of larval red drum Sciaenops ocellatus.Larvae in T_8 group had higher survival and better growth than those in T_0 and T_4 groups,but there was no significan difference in growth and survival of larvae between T_0 and T_4 groups.The mortality of larvae in T_8 groups was significantly lower than those in T_0 and T_4 groups,when subjecting the larvae to a standardized salinity stress or exposed to air for a few minutes.These results suggest that supplemental levels of taurine markedly affected stress resistance of Sciaenops ocellatus larvae. |
