Growth performance and histological response of Clarias gariepinus raised on unprocessed dried leaves of Telfairia occidentalis and Mucuna utilis

Nutrient utilization is determined by absorbable and digestible nutrients in fish feeds. The aim of the experiment was to investigate effects unprocessed dried leaves Telfairia occidentalis (UDLTO) Mucuna utilis (UDLMU) on histology growth C. gariepinus. Sixteen weeks feeding trial conducted using two hundred twenty-five Clarias gariepinus with a mean weight 4.16±0.09g. Fish meal replaced 0, 25, 50, 75 100% levels UDLMU UDLTO. Growth parameters histological examinations were carried out according standard procedures. Mean Weight Gain (MWG) 0% (15.8g) significantly higher P0.05 compared other treatments. Specific Rate (SGR) (0.64) varied than inclusions. Kidneys fed 25 50% graded showed patchy vacuolar degeneration renal tubules. Gills diffuse capillaries moderate congestion lamellar gills.
