Heterobranchus longifilis catfish is an important aquaculture fish species in the West African sub region. The culture of this fish is based on a diet containing up to 30% maize as a source of energy. We assessed the serum biochemical and lipids profile of this fish following dietary exposure to graded concentrations of fumonisin B1 (FB₁). 450 juvenile H. longifilis catfish were stocked into 5 groups of 1000 L tanks consisting of 3 tanks per group and fed one of five experimental diets amended with purified FB₁ (0.0; 10.0; 20.0; 20.0; 40.0 and 80.0 mg FB₁/kg) for 56 days. At time point’s day 7, day 28 and day 56, five fish each were randomly sampled from each tank and bled for serum biochemical and lipids profiling. Results shows that the experimental diets had greater FB₁ concentration (2.37; 14.68; 24.74; 43.04 and 82.77 mg FB₁/ kg), compared to the concentration of purified FB₁ added at the time of production of the diets. Dietary FB₁ at inclusions ≥ 24.74 mg FB₁/kg caused a nonspecific dose and duration of feeding dependent changes in serum biochemical parameters marked by hypoprotenemia, hyperalbuminemia and increased serum activities of alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, creatinine, urea and lactate dehydrogenase compared to fish fed the control diets. Other changes observed in H. longifilis catfish juveniles following dietary exposure to FB₁ include hypercholesterolemia and hypertriglycerolemia. It was concluded that for profitable H. longifilis culture, dietary FB₁ should not exceed 24.74 mg FB1/kg.
