17.1.1 Eye stalk ablation - origin
It was earlier understood that the endocrine glad present in the eyestalk of the crustaceans is responsible for the blocking of certain activities connected with the gonaldal maturation. It has been named as X organ sinus glad and sinus complex, that secretes Moulting Inhibiting Hormone (MIH). It is also termed as Growth Inhibiting Hormone (GIH) since it inhibits growth in general. Therefore removal or blocking of this hormone from its activitiy is believed to help in the speedy maturation of the animals. Panouse (1943) observed that removal of eyestalk of shrimp Palaemon serratus led to ovarian development. Ever since this discovery several workers have tried to induce gonadal maturation in prawn through ablation of eyestalk and also the breeding of different crustacean. |
