Abstract
Water conductance, time after fertilization and female size (length and weight) were tested for their effect on diameter of C. commersoni (Lacepede) eggs. Conductance was inversely related to egg diameter. A female effect was found in 1 experiment but not in the other. The relationship between female size and egg diameter was weak. Variability due to conductance was less than the natural variability found in field samples. Larger sizes were manifested in larger perivitelline spaces and attributable to higher ionic concentrations in the water.This publication has 2 references indexed in Scilit:
