Abstract: The growth performance, survival and reproductive success of Clarias gariepinus broodstocks were examined as they responded to 17- α-methyl testosterone (MT) and absolute ethanol mixed in their feed in varying levels of 50 mgKg-1 /MT, 100 mgKg-1 /MT and 0 mgKg-1 /MT. These inclusion levels also served as the three treatments TC 50, TC 100, TC 0. A total of 24 Clarias gariepinus broodstocks were stocked in six (6) concrete stagnant systems of 4 (2 males, 2 females) fishes per tank of 2metre by 2metre square, with duplicated treatments of TC 50 and TC 100. Treatment TC 0 was also duplicated, and served as the control, with 4 fishes per tanks (2 males and 2 females). Duration was for ninety (90) days. The mean initial weights were taken as 2.05 ±353.56g for treatment TC 50, 1.60 ±282.84g for treatment TC 100 and 1.65±494.98g for treatment TC 0. Highest mean weight gain of 3.45±2.22g observed in the study was seen in the Clarias gariepinus broodstock tank TC 50. Performance index showed treatment TC 50 performed highest with value 601.85±239.09. Survival rate was high in treatment TC 50 with 50.0±0.00%, higher in treatment TC 0 with 62.50±17.68% and highest in treatment TC 100 with 87.50±17.68%. Condition factor K was greater than 1 throughout the study showing well-being of the fishes; highest in treatment TC 50 at value 7.20. Water quality parameters were at normal ranges throughout the study.
