　　采用形态学的方法对普安银鲫仔、稚鱼的发育和生长进行研究。试验结果表明，在水温22～25℃培养条件下，普安银鲫52 h 出膜，刚出膜仔鱼较为透明，头部紧靠卵黄囊，卵黄囊占整个仔鱼体积的2/3；4日龄仔鱼，卵黄囊消失，仔鱼开始进入外源营养期；20日龄仔鱼有少量鳞片出现，个体进入稚鱼期；28日龄全身披鳞，个体进入幼鱼期。对仔鱼、幼鱼30 d 全长和日龄进行回归分析，其生长模型为TL ＝0．0012D3－0．0388D2＋1．0432D ＋3．9458（r2＝0．998），体质量与体长的相关式为 m ＝1E －0．5 L3．3769（r2＝0．9827），体高与体长的相关式为 H ＝0．0001 L3－0．0284L2＋1．2816 L －7．2505（r2＝0．9886）。本研究结果可为普安银鲫的生产实践提供有益的理论指导。

The growth and development of larvae and juveniles was morphologically investigated in Puan sliver crucian carp Carassius auratus Linnaeus .The results showed that it took 52 h from fertilization to hatching at 22 ~ 25 ℃ .The newly hatched larvae had transparent body ,with the head right near the yolk sac ,accounting for two-thirds of the body length ,which was exhausted in the 4 day old post-larvae which started the exogenous nutrient period .The post-larvae were found to develop into juveniles from a few scales on the 20th days after hatching to whole scales ,fingerling ,on the 28th day after hatching .The relationship between total body length (TL) and age in day (D) was described as :TL = 0 .0012D3 - 0 .0388 D2 + 1 .0432 D + 3 .9458(r2 = 0 .998) .The relationship between body length (L) and body weight (W) of the larvae and juveniles was expressed as :m= 1E - 0 .5L3 .3769 (r2 = 0 .9827) .The formula between body length and body height during the development of the fish was described as :H = 0 .0001L3 - 0 .0284L2 + 1 .2816L- 7 .2505 (r2 = 0 .9886) .The findings contribute to provide the theoretical instruction to fry and juvenile production of Puan sliver crucian carp .
