The mean hourly tempera- ture was ° C. (° F.), standard deviation, ° C. (° F.).. of its maternal parent species, revealed that WB Fi hybrid zygotes hatched sig- nificantly sooner than pure bluegill zygotes when both kinds of zygotes were incubated at the same tempera- tures. Although WB zygotes hatched in less time, the newly emerged WB Fi larvae were not as advanced in their development as the unhatched pure bluegill embryos. WR F, liybrids were not significantly different from pure red-ears in hatching time; however, the newly emerged WR larvae were not as advanced in their development as the pure red-ear larvae. There were no statistically significant differences in the time of hatching between the other 10 kinds of hybrids and their respective.
