Shrimp, like all decapod crustaceans, are recognized by the scientific community as sentient beings capable of experiencing pain and distress. 

Several European countries, including the United Kingdom, Switzerland, Austria, and Norway, have integrated this information into their animal welfare laws to establish standards for decapod farming.

Reproductive female shrimp are subjected to a cruel and painful practice known as eyestalk ablation, purportedly to enhance productivity.

Eyestalk ablation consists of cutting off one or two eyestalks from a female shrimp using a razor blade or hot scissors, while fully conscious and without the use of anesthetic. This procedure has become a standard practice in the shrimp industry, as it is believed to significantly increase the number of eggs laid, subjecting shrimp to severe mutilation. 

However, recent scientific studies have demonstrated that eyestalk ablation is not only inhumane but also entirely unnecessary for maintaining productivity. This practice can lead to increased mortality rates, making weak larvae more susceptible to disease. Research indicates that comparable productivity levels can be achieved by altering shrimp feed.
