Latency period: eyestalk ablation to ovarian development
Once females have been subjected to eyestalk ablation, complete ovarian development often ensues within as little as 3 to 10 days, assuming the animals were removed from a breeding or ready-to-breed population, of adequate size for reproduction, and not subjected to too much transfer stress. If the animals have been removed from non-conducive environmental conditions (e.g, cold, non-breeding season temperatures, or hypersaline conditions), a longer than normal latency period between eyestalk ablation and ovarian development can be anticipated, probably due to seasonal hormonal cycling. Duration of the latency period between eyestalk ablation and maturation of ovaries is determined by the readiness of the population at the time of eyestalk ablation (Bray & Lawrence, 1992).
