卵的活力在彩虹镖鲈Etheostoma caerurous，鱼显然缺乏雌性配偶的选择，被发现排卵后迅速下降。据观察，如果阻止雌性交配时间短至6 h，则大多数雌性窝卵可能无法孵化。这些数据表明，行使女性择偶偏好可能是有选择性的不利在E。caeruleum由于延迟交配的高成本。
Egg viability in the rainbow darterEtheostoma caeruleum, a fish apparently lacking female mate choice, was found to decline rapidly after ovulation. It was observed that the majority of a female's clutch may fail to hatch if she is prevented from mating for as little as 6 h. These data suggest that exercising female mate preferences may be selectively disfavoured inE. caeruleumdue to the high cost of delaying mating.
