Eyestalk ablation is a surgical procedure often performed on crustaceans, such as shrimp and crabs, to remove the eyestalks, which are responsible for producing hormones that regulate growth and reproduction. This procedure is commonly used in aquaculture to enhance growth rates and increase production by eliminating the inhibitory effects of eyestalk hormones. Following ablation, crustaceans typically exhibit accelerated molting and growth, making them more suitable for farming. However, the long-term effects on health and behavior require careful consideration.
