Özet:

 

A study was conducted to determine the comparative reproductive, growth performances and nutrient utilization of Clarias gariepinus and its hybrid "heteroclarias" using ovaprim and pituitary extract of male and female C. gariepinus. The experimental broodstocks consisted of 6 female C. gariepinus (2 each were induced separately with ovaprim, male pituitary of C. gariepinus and female pituitary of C. gariepinus), 3 male C. gariepinus and 3 male Heterobranchus bidorsalis. 2 female C. gariepinus induced with synthetic hormone were crossed separately with male C. gariepinus and male H. bidorsalis. A similar crossing was done for the other two sets of female C. gariepinus induced with male and female pituitary glands. The result shows that there was significant difference (P<0.05) among the treatments in all the reproductive performance, growth and nutrient utilization parameters. The highest percentage fertilization (88.44±5.74%), feed intake (27.48±7.08g), protein intake  (15.39±3.96g), feed conversion ratio (1.21±0.12) and protein efficiency ratio (1.68±0.19) were recorded in pure line C. gariepinus induced with ovaprim. Pure breed C. gariepinus also had the highest values in all the reproductive performance and growth parameters. This study has shown that C. gariepinus induced with synthetic hormone (ovaprim) produce offspring  with better qualities than those induced with pituitary.   	 	 		 .
