Abstract High cost and scarcity of feed ingredients have continued to challenge the aquaculture. This present study assessed potential black soldier fly (BSF, Hermetia illucens L.) larvae meal (BSFLM) as a sustainable alternative source animal protein in diet African catfish (Clarias gariepinus), species widely farmed Cameroon for its breeding economic. Five formulations: control with 100% fishmeal (FM, BSFLM0), diets where FM was substituted at 50% (BSFLM50), 75% (BSFLM75), (BSFLM100) levels, were compared. Larvae BSF processed using three different methods: toasting, sand boiling. Parameters included chemical microbial properties larvae, growth performance, health, consumer acceptance economic viability substituting BSFLM. Our results demonstrate that boiling significantly increased dry organic matter contents but reduced crude (CP) fat whereas toasting CP. Mineral content varied across processing had highest calcium, iron, potassium, sodium, phosphorus levels. Sand-toasted Escherichia coli Lactobacillus only boiled there no Enterobacteria or Salmonellain toasted sand-toasted samples. At higher levels (75-100%), BSFLM improved rates, conversion ratio, survival compared control. Replacing also production costs, profitability, enhanced sustainability, indicated by lower fish-in-fish-out ratio. Inclusion enhances sustainability aquaculture practices reducing reliance on wild-caught fish feed. Overall, is suitable can support environmental aquaculture, promoting resilient farming practices.

The black soldier fly ( Hermetia illucens ) is a saprophagous insect known for bioconverting organic waste, potentially offering environmental benefits, such as contributing to waste reduction and nutrient cycling. performance of larvae varies significantly with factors substrate moisture, larval density, scale production. Three experiments were conducted using mix spent mushroom (SMS) chicken feed (CF). In the first experiment, 250 reared on 100 g dry matter (DM) at moisture levels 65–75%. Results showed that average individual weight, total biomass, conversion ratio (FCR) improved increased moisture. second 300 350 larvae/box tested 70% 75% highest fresh weight (158.6 mg) was observed larvae, while biomass achieved larvae. Finally, different scales (10–2,500 25–6,500 larvae) similar feeding rate. recorded scale, no clear correlation between scale. However, 50 (33.2%). Overall, this study underscores need adjust efficiency when SMS, CF or other diets. optimal results SMS per DM, approximately 2 cm .

Feeding low crude protein (LCP) diets supplemented with crystalline amino acids improves environmental and welfare parameters of broilers. However, increased body fat contents in broilers fed LCP have become a concern. Black soldier fly larvae oil (BSFLO), rich lauric acid, has been reported to inhibit lipogenesis reduce fat. A 3 × 2 factorial experiment was conducted evaluate the effect BSFLO on performance, blood biochemistry, carcass quality, metabolism gene expression, litter quality protein-reduced diets. total 288 were divided into 6 treatments: three CP levels (200, 185, or 170 g/kg; high [HCP], medium [MCP], [LCP]) two sources (BSFLO Crude Palm Oil [CPO]), replicate pens 8 birds each. Results showed 15 g/kg reduction had no weight feed intake (P > 0.05) but FCR = 0.001). 30 significantly reduced inferior < 0.05). negative mitigated by 0.008).

Aquafeed production is a fast-growing industry, seeking novel, cost-efficient raw materials to diversify traditional ingredients like fish meal and oil. Insects, particularly BSF larvae, convert by-products waste into value-added biomass. In this study, co-products from two major fish-transforming industries in the Iberian Peninsula, i.e., tuna heads (THs) codfish frames (CFs), hydrolysates of THs CFs, TH oils, were supplied larvae improve their profile n-3 fatty acids (FAs), namely EPA DHA, protein/amino acid content. By testing replacement levels control diet with co-products, we evaluated amount FA that could be added larval tissues. The results showed high hydrolysed negatively impacted survival. addition, parameters such as moisture, protein content, viscosity substrate affected bioconversion rates. Nevertheless, fed these diets contained lysine (5.8–8.4%, dry weight (DW)), methionine (1.5–2.4%, DW), (14.4% DW: 6.7% DHA 7.1%). These findings suggest can effectively nutrient-rich biomass for aquafeeds, supporting diversification material sources promoting circular bioeconomy.

As the world's population increases, growing demand for food intensifies generation of agricultural waste, leading to several environmental issues. Intensive research indicates black soldier fly (BSF) larvae Hermetia illucens (Linnaeus, 1758) as efficient converters organic waste into nutrient-rich biomass suitable animal feed. Using a structured questionnaire and volunteer farmers (N = 595), we investigated potential adoption BSF composting technology sustainable management in Greater Ahafo-Ano. Almost all surveyed declared they generated significant amount biowaste on their farms were willing learn how use BSF-based transform it value-added products. The was mainly disposed pits at Ahafo-Ano South-East (56.2%), by South-West (34.9%) sale North (34.4%). Across three districts, awareness very low – 14.5% South-East, 14.1% 0.5% North. However, high acceptance recorded. It found that about 8% had already tried farming small scale. Indicating this district good entry point introduce
