Does this hurt prawns? Science indicates it does – and shockingly, it isn’t necessary
Scientists have found that prawns who have their eyes cut off become disoriented, flick their tails (an escape reflex) and rub the traumatised area — all behaviours associated with pain.
Research has found that, given the right environment, female prawns will breed without having their eye cut off. Even the Global Seafood Alliance has published research stating ‘eyestalk ablation’ is not necessary – and also leads to prawn offspring being more vulnerable to disease.
One of Latin America’s largest group of prawn farms, SeaJoy, has already phased out this gruesome procedure.
