Oreochromis niloticus
Since female Nile tilapia exhibiting parental care show extended interspawning periods, one of the benefits is slowing down vitellogenesis (yolk deposition) to increase the survival rate of one's own young. The size of spawned eggs correlates directly with advantages concerning hatching time, growth, survival, and onset of feeding, since increased egg size means increased nutrients for the developing young. Thus, one of the reasons behind a delayed interspawning period by female Nile tilapia may be for the benefit of offspring survival.
