Study was conducted to investigate the effects of dietary fenugreek seed meal (FSM) on the growth performance, haematology and antioxidant profile of juvenile African carp (Labeocoubie ) fish exposed to Deltamethrin . 450 fish were allotted into any of 5 groups 1000 L capacity tanks (consisting of three replicate per group). Each group was fed any of five experimental diets amended with 0% (group A, positive control), 0% (group B, negative control), and diets C, D and E (5%, 10% and 15% FSM respectively), for 56 days. Fish cultured in Deltamethrin contaminated water and fed the basal diet (group B) exhibited significant (P < 0.05) reduction in weight gain, specific growth rate and a significant (P < 0.05) increase in the feed conversion ratio compared fish fed the same diet but cultured in water free from Deltamethrin . There were significant increases in the erythrocytes and leucocytes numbers in fish fed the basal diet and cultured in Deltamethrin contaminated water compared with fish fed the same diet but cultured in water free from Deltametrin . Deltametrin exposure caused significant increases in glutathione reductase and malondialdehyde concentration and a significant reduction the superoxide dismutase, catalase and glutathione transferase activity. Dietary fenugreek seed meal at 5% 10% and 15% inclusion elicited significant reduction in the glutathione transferase and malondialdehyde concentration in fish cultured in Deltamethrin contaminated water.
