Unilateral eyestalk ablation
The process of unilateral eyestalk ablation is used in almost every marine shrimp maturation/reproduction facility in the world, both research and commercial, to stimulate female shrimp to develop mature ovaries and spawn. This method of inducing females to develop mature ovaries is used for two reasons:
  1. most captive conditions cause inhibitions in females which keep them from developing mature ovaries in captivity
  2. even in conditions where a given species will develop ovaries and spawn in captivity, use of eyestalk ablation increases total egg production and increases the percentage of females in a given population which will participate in reproduction
