This experiment was conducted to evaluate the effect of cottonseed meal and cotton seed flour on the reproductive behavior and on the testis activity of Nile tilapia broodstock. Twenty-five fishes were fed diets containing 0, 2, 4 and 6% ground cottonseed flour and 24% cottonseed meal (CSM). The reproductive behavior of the fishes was daily observed and the nest construction, courtship and spawning were evaluated. At 90 days, the males gonads were microscopically evaluated. The control group (soybean meal) showed […]
