| Abstract | ||
| In this study we have investigated the effect of water levels (20, 40, 60 and 80 cm of water column) on spawning and reproductive behavior of red tilapia hybrid. Two spawnings were obtained during the experimental period except for fish of 20 cm of water depth treatment did not give any seed production. It was noted that there are significant differences (P<0.05) between the treatments for the two spawnings. The fish of third treatment were recorded the best results in most reproductive performance parameters while the fish of second treatment were recorded the least results. The results revealed that the fish of third treatment were the most numerous egg number 988.0±19.49 egg/fish and the fish of first treatment were recorded the fewest egg number 576.0±8.38 egg/fish. | ||
