Use some sexual stimuli to induce hormone in normal carp Cyprinus carpio A - Aldombridon *

Abstract

the use of domperidone was compared with the usually used dose ( 4 mg/kg for female and half of it for male) in the hormonal treatment of common carp, the study was done in one of the private hatcharies in Babel province from 1st to 20th of April 2012.Three trials were done, in each trial fishes were divided into two groups (treatment T, control std) (T1: 10 mg/kg domperidone with 0.4 mg/kg pituitary gland for female and 10 mg/kg domperidone for male, T2: 10 mg/kg domperidone with 2 mg/kg pituitary gland for female and half of it for male, T3: 10 mg/kg domperidone with 1 mg/kg pituitary gland for female and half of it for male). The female traits that were studied are (response percentage, response time after second dose, eggs weight, fertilization percentage, percentage of eggs weight to female weight, average of egg diameter, eggs number in kg of eggs, dose cost for kg of female, dose cost for kg of eggs) and for males (semen volume, percentage of semen volume to male weight, dose cost for kg of female). Results show ability to use domperidone (10 mg/Kg for female and half of it for male) with half or quarter used pituitary gland without effect on results of artificial propagation for production traits for males and females and this made able to reduse cost to 350 dinars for female after it was 1200 dinars and 175 dinars for male after it was 600 dinars.
