Abstract
This study evaluated the growth performance, carcass proximate and mineral composition, and haematological indices of Clarias gariepinus fingerlings fed diets containing dung beetle larvae meal (Aphodius rufipes) and black soldier fly larvae meal (Hermetia illucens) as fishmeal replacements. Seven isonitrogenous diets containing 40% crude protein were formulated: T1 (0% insect meal), T2 (5% inclusion of ARLM and 5% of HILM), T3 (10% inclusion of ARLM and 10% of HILM), T4 (15% inclusion of ARLM and 15% of HILM), T5 (20% inclusion of ARLM and 20% of HILM), T6 (25% inclusion of ARLM and 25% of HILM) and T7 (30% inclusion of ARLM and 30% of HILM). A total of 420 fingerlings were stocked at 20 fish per plastic aquarium (45 × 30 × 24 cm3) in triplicate and fed for 10 weeks. The results showed significant differences (p<0.05) in growth performance and nutrient utilisation. Higher mean weight gain (31.19 g), feed efficiency (1.00), specific growth rate (4.21%), protein efficiency ratio (0.78), protein retention (42.38%), and average daily gain (0.45 g) were recorded in T5, while apparent net protein utilisation was highest in T4. Carcass crude protein was highest in T4 (58.45%) and lowest in T7 (54.87%), while ether extract increased from 10.42% to 13.72% with increasing insect meal inclusion. Sodium, potassium, phosphorus, and calcium contents also increased with inclusion levels of insect meals. Haematological indices showed increases in red blood cells, haemoglobin, packed cell volume, white blood cells, lymphocytes, and platelets, while monocytes and neutrophils decreased. These findings suggest that combined A. rufipes and H. illucens larvae meals can serve as alternative protein sources in diets for C. gariepinus fingerlings, with T5 giving the optimal overall growth performance.
