Effects of dietary black cumin (<i>Nigella sativa</i> L.) oil on growth performance, hemato‐biochemical and histopathology of cypermethrin‐intoxicated Nile tilapia (<i>Oreochromis niloticus</i>)

This study was conducted to investigate the effects of dietary black cumin (Nigella sativa L.) oil on growth performance, hemato-biochemical, and histopathology cypermethrin-intoxicated Nile tilapia. After determining LC50 (96 h) value cypermethrin, cypermethrin added water at a ratio 1:20 this concentration, fish were fed for 42 days. To reduce 1% feed as potential protectant. Growth parameters, hematology, blood biochemistry, histopathological changes tilapia examined after feeding period. In study, best observed in group with containing oil, while worst performance without feed. As result it that diet reduced negative water-borne growth, parameters
