Abstract

Nigella sativa or black cumin seed growing worldwide as annual herb having significant medicinal importance. Current investigations revealed the efficacy of black cumin at selected levels of concentrations (0%, 1%, 2%, 3% and 4%) in fish feed effecting muscles proximate and composition of fatty acids in grass carp (Ctenopharyngodon idella). A total of 150 fingerlings consisting average body weight of 16.2 ±0.1g and divided into five groups, each having five replications fed with experimental diets using 4% of body weight two times in a day for 63 days. Consequently, muscles protein, crude fat, ash and moisture content in grass carp were increased significantly using proximate analysis at 3% concentration of black cumin. Fatty acid profile including both saturated and polyunsaturated fatty acids were also checked because of dietary black cumin; it was determined that saturated fatty acids reduced. However, polyunsaturated fatty acids increased at 3% of dietary black cumin. Herein, it is proved that, the 3% concentration level of supplemented diet (black seed) has potential to maximize the fish production acknowledging the high nutritional values
