Observation of topical gill application of ovaprim and DMSO for induced spawning of comet (Carasius auratus auratus)

Abstract

An alternative way to induce fish to spawn is topical gill aplication. This research was conducted to evaluate the use of ovaprim and DMSO as a solvent for topical gill aplication to induced spawning of comet ( carassius auratus auratus ) Four treatment groups was avaluated : (1) topical gill application of 0.3 ml/kg BW dimetil sulfoxide (DMSO), (2) topical gill application of DMSO+ ovaprim ,and (3) topical gill application of 0.3 ml/kgBW of ovaprim and (4) an ovaprim intrumuscular (IM) injection. The result showed that the best injection for ovulation was the application of gill with dose DMSO 0,3 ml/kg body weight + ovaprim 0,3 ml/kg body weight, where it could generate a laten period of 1658 grains, the number of impregnation was 28,69 %, the number of hatching rate was 17,90 % and the highest number of alive was in treatment of gill aplication with dose DMSO 0,3 ml/kg body weight with amount of 91,82%.
