3.3. Relationships between larval survival, morphology and culture factors
Fig. 4 shows the relationships between the larval survival, morphological
measurements and culture factors. The results of the GLMM
analysis are summarized in Table 3.
The larval culture factors had no significant effects on the survival
rates during the transition from the first-stage zoeae to juvenile crabs,
from the fourth-stage zoeae to megalopae and from megalopae to
juvenile crabs, according to the GLMM (P N 0.0796) (Fig. 4A).
The coefficients of all the explanatory variables (morphological
measurements) of the fourth-stage zoeae for the survival rate during
the transition from the first-stage zoeae to juvenile crabs were not statistically
significant, according to the GLMM (P N 0.101) (Fig. 4B),
whereas those for the megalopae were significantly related to the survival
rate (P b 0.003) (Fig. 4C). All of the coefficients were negative,
and the survival rate tended to decrease as the morphological
