Table 3.
Survival, mean bilateral asymmetry over three traits, body size for females and males, and brood size, both for wild-caught and for captive-raised fish from four different populations (P indicates level of significance, and NS indicates not significant) (Sheffer et al. 1997). All P < 0.01 values are significant after a Bonferroni’s correction. Also given is the duration of male development in days (Cardwell et al. 1998)
