在养殖水温为(26.62±1.19)℃时,规格为1.03~10.95 g/只的幼蟹蜕壳后,体重平均增长率为(45.515±15.630)%,壳长增长率为(10.159±5.687)%,壳宽增长率为(9.994±5.302)%,壳长/壳宽增长率为(1.235±0.712)%。其中不同规格组蟹的体重和壳长/壳宽的增长率没有显著差异,而壳长、壳宽增长率变化幅度较大,与体重的关系不明显。所蜕壳的干重占蜕壳前后体重的比率分别为(16.159±5.734)%和(11.319±3.648)%,两者都随体重的增加而趋于减小。
The average growth rate of body weight was (45.515 ± 15.630)% and the growth rate of shell length was (10.159 ± 5.687)% when the juvenile crabs with the specifications of 1.03 ~ 10.95 g / (9.994 ± 5.302)%, and the growth rate of shell length / shell width was (1.235 ± 0.712)%. There was no significant difference in body weight and shell length / shell width among different groups of crabs. However, the growth rates of shell length and shell width varied a lot, but their relationship with body weight was not obvious. The percentage of body weight before and after molting was (16.159 ± 5.734)% and (11.319 ± 3.648)% respectively, both of which tended to decrease with the increase of body weight.
