Abstract

Utilizing black soldier fly larvae (BSFL, Hermetia illucens) as an alternative protein source to replace fishmeal (FM) in aquaculture feeds is gaining popularity. This research assessed the effects of various BSFL inclusion levels (0, 25, 50 and 100%) in commercial fish feeds on the growth performance and skin mucus immunity of snubnose pompano (Trachinotus blochii). In the study, 30 snubnose pompano (2.669 ± 0.219 cm in total length) were divided into triplicate groups and raised in 20-litre tanks, each fed with different diets. After a four-week feeding trial, body parameters were measured for 10 fish per tank, and skin mucus samples were collected for lysozyme assay. The results showed that up to 50% BSFL inclusion had no significant impact ( p > 0.05) on fish growth (final body weight and length, percentage weight gain and length gain, specific growth rate, condition factor). However, the 100% BSFL diet adversely affected fish growth, resulting in the lowest performance among the treatments. Diets with 0%, 25%, and 50% BSFL showed significantly higher feed conversion efficiency and lower feed conversion ratio ( p < 0.05) compared to the 100% BSFL diet. Consequently, the 100% BSFL diet treatment incurred significantly higher feed costs than diets containing up to 50% BSFL. The survival rate and skin mucus immunity of snubnose pompano were not significantly influenced by any level of BSFL inclusion ( p > 0.05). These findings suggest that BSFL can be effectively included up to 50% in snubnose pompano diets without compromising growth performance and fish immunity.
