| Abstract: | To understand the reproductive biology characteristics of cultured Sepiella maindroni, the mantle length (ML), body weight (W), net body weight (Wn) and ovary weight (Wo) were measured, then the gonadosomatic indices (GSI), condition factor (CF) and individual fecundity were calculated. Based on these biological data, the variant regularity of GSI and the relationship between the individual fecundity and the biological character indices were studied. The result showed that the GSI of spring seedling reached the highest 12.2%±3.25% in 100 days-old; that of autumn seedling reached the highest 13.7%±3.69% in 140 days-old. There were no significantly different between spring seedling and autumn seedling on the fecundity (F), absolute fecundity (Fa) and relative fecundity FML (P>0.05), the relative fecundity FW of autumn seedling was significantly higher than that of spring seedling (P<0.01) by analysis of variance (ANOVA). The relationships between the F, Fa, FML and the ML, W, Wn, Wo could be expressed in power or exponential functions (P<0.01). There was significant (P<0.01) positive linear correlation between FW and ML. The relationships between the GSI and the Fa could be expressed in linear or power functions (P<0.01), while the GSI had no significant relationship with others individual fecundity indices (P>0.05). There was significant (P<0.01) negative correlation between individual fecundity and CF. Multi-regressive analyses showed that the individual fecundity were significantly correlated with ML and CF. The fecundity were mainly dependent on the size of ML. |
