    Abstract:
    The proximate composition, sensory attributes, and shelf life of filets from barramundi, Lates calcarifer, were fed a fishmeal (FM) based diet (0PBM-0HI) and three test diets replacing FM protein entirely with 85% poultry by-products meal (PBM) and 15% Hermetia illucens (HI) larvae meal protein (85PBM-15HI), 80% PBM and 20% HI (80PBM-20HI) and 75% PBM and 25% HI (75PBM-25HI) were investigated. After a 56-day feeding trial, the crude protein, moisture, and ash percentage were unchanged while the crude lipid increased in barramundi filet when fed with PBM-HI-based diets. The increase in C12:0 (lauric acid) and C14:0 (myristic acid) resulted in an increase in the total saturated fatty acid while the monounsaturated fatty acid elevated due to an increase in C16:1n7 and C18:1cis + trans in the filet of the barramundi fed with a PBM-HI based diet. While the decrease in the total polyunsaturated fatty acid (PUFA) content in PBM-HI based fed barramundi filet was mainly due to a decrease in essential fatty acids including C20:5n3 [eicosapentaenoic acid (EPA)] and C22:6n3 [docosahexaenoic acid (DHA)] when compared with the 0PBM-0HI fed barramundi filet. The sensory quality was improved by PBM-HI-based diets, manifested by the highest scores given by the panelists. Texture profiles were not affected by diet but cohesiveness, gumminess, and chewiness decreased with increasing storage time. On days 1 and 8, skin brightness decreased in the skin of the barramundi fed with 85PBM-15HI and 80PBM-20HI compared with the skin of the 0PBM-0HI fed barramundi. Skin redness improved in fish-fed PBM-HI-based diets. The flesh brightness and yellowness increased significantly in barramundi when fed with PBM-HI-based diets. On days 1 and 4, the flesh brightness of the barramundi fed with PBM-HI-based diets demonstrated an increase compared with 0PBM-0HI. PBM-HI diets suppress lipid oxidation while lipid oxidation increased over the storage time. In summary, the improvement in sensory quality and color coupled with the suppression of rancidity in barramundi filets underpinned the potentiality of using the mixture of PBM and HI transformed from food waste in the barramundi diet to improve the filet quality and thus support sustainability and circular economy in aquaculture.
