摘　　要：温度对池沼公鱼(Hypomesus olidus)仔鱼生长和发育的影响研究表明,水温(12±0.5)℃、(16±0.5)℃和(20±0.5)℃时,其仔鱼均能正常生长发育;随温度升高,仔鱼全长生长加速,卵黄囊和油球吸收变快。在12～20℃温度范围内,温度每升高4℃,仔鱼的全长、卵黄囊和油球变化差异显著(P<0.05)。当温度达到24℃时,仔鱼卵黄囊和油球不能正常吸收,生长受到抑制,与其它3组相比差异显著(P<0.05)。研究表明,水温12～20℃,池沼公鱼仔鱼可以正常生长。The effect of temperature on growth and development in larval pond smelt Hypomesus olidus was researched.It was found that the larvae can grow and develop normally at（12±0.5）℃,（16±0.5）℃ and（20±0.5）℃,and full length growing was fast with the temperature rise,while the yolk sac and oil ball absorbed was fast,too.The difference was significant（P0.05）.When the temperature reached 24℃,the larvae could not absorb yolk sac and oil ball,and the growth was inhibited.Compared with the other three groups,the difference was significant（P0.05）.The results showed tha larvae of Hypomesus olidus could grow normally at the temperature range as 12-20℃.
