摘要: 为了探索杂交东方鲀(菊黄♀×暗纹♂)胚胎孵化和早期仔鱼生长发育最适宜的盐度条件,比较其在0、5‰、10‰、15‰、20‰、25‰、30‰、35‰、40‰、45‰等10个盐度梯度下,杂交东方鲀的受精卵发育和仔鱼生长情况。结果显示:杂交东方鲀受精卵在5‰~45‰盐度范围内均可孵化,适宜盐度为15‰~35‰,孵出期(y)与孵化时间(x)的存在着非线性相关,其回归方程为y=-1245.366+15.543x-0.048x2(R2=0.911)。仔鱼生长的最适盐度范围为15‰~30‰,在该范围内不存在显著性差异(P>0.05)。试验结果表明,杂交东方鲀受精卵发育与仔鱼生长的适宜盐度为15‰~30‰,在该盐度范围内,杂交东方鲀能正常的发育生长。

Abstract: To investigate the most suitable salinity condition for the embryo hatching and larval growth of hybrid puffer (Takifugu flavidus♀×Takifugu obscures♂), fertilized eggs hatching and larval growth were observed under the conditions of different salinities, namely 0, 5‰, 10‰, 15‰, 20‰, 25‰, 30‰, 35‰, 40‰ and 45‰. The results showed that fertilized eggs of hybrid puffer could hatch under salinity of 5‰~45‰, and 15‰~35‰ was the optimal salinity range. Hatch period (y) had nonlinear correlation with incubation time(x), the regression equation was y=-1245.366 15.543x-0.048x2(R2=0.911). The optimal salinity range for larval growth was 15‰~30‰, and there was no significant difference in the optimal salinity range(P>0.05). All the results indicated that the optimal salinity range of fertilized eggs hatching and larval growth of hybrid puffer (Takifugu flavidus♀×Takifugu obscures♂) was 15‰~35‰, development and growth of hybrid puffer was normal in this range.
