Effect of black cumin oil (Nigella sativa) on the growth performance, body composition and fatty acid profile of rainbow trout (Oncorhynchus mykiss)

            In this study, rainbow trout were fed for a total of 144 days with different feed mixes containing 0.00%, 0.10%, 0.40%, 0.70%, 1.00% and 1.30% black cumin oil. The effect of black cumin oil on the growth performance, feed content and fatty acid composition of rainbow trout was researched. The starting weight of fish in the experimental group was approximately 60 gr., which increased respectively to 215.21±4.12gr, 217.32±3.14gr, 235.12±2.9gr, 240.21±6.5gr, 260.14±4.7gr, and 258.89±1.6gr, while the difference in growth between the groups was observed to be statistically significant (p
