At the research station here of the Southeast Asian Fisheries Development Center (Seafdec), researchers may be considered 'sadists': They are inflicting painful injuries to female prawns by pinching or crushing their eyestalks. Or sometimes, they ligate, cauterize or cut the eyestalks, causing the poor animals to become blind in one eye.
