This study evaluated superworm (Zophobas morio) larvae meal as a novel protein and carotenoid source in diets of goldfish, Carassius auratus.A six-months feeding trial was carried out to estimate the effect of dietary replacement of fishmeal with superworm meal at graded percentages on growth performance, survival, digestive enzyme activity and carotenoid content in skin and muscle tissue of goldfish.Five iso-nitrogenous diets were formulated with 38% of crude protein, substituting fishmeal protein with superworm meal protein at the levels of 0% (D0, control), 25% (D25), 50% (D50), 75% (D75), and 100% (D100), containing 0%, 10.59%, 21.18%, 31.77% and 42.35% superworm meal resp.Escalating the percentage of superworm meal inclusion led to a significant improvement in growth, feed utilization, digestive enzyme activity, survival and carotenoid deposition in skin and muscle tissue of goldfish.Thus, complete replacement of fishmeal protein with superworm meal protein with an inclusion level of 42.35% of diet would be recommended for goldfish.
