Dried black soldier fly larvae meal, Hermetia illucens, has been successfully used as a protein source in the feeding of terrestrial animals. This ingredient can also be incorporated in the formulation of fish and shrimp diets. The aim of the present study was to evaluate the effect of different inclusion levels of a black soldier fly larvae meal (BSFLM) as a protein source in diets for juveniles of Litopenaeus vannamei. Five isoproteic diets were formulated, one as control (CTL) with 7.00% (% of diet, as is) of poultry viscera and bone meal (PVBM). In the other diets, PVBM was included at 7.00, 5.75, 4.43 and 3.05% in combination with 1.00, 3.00, 5.00 and 7.00% of BSFLM, respectively. Shrimp of 7.63 ± 0.42 g (mean ± standard deviation) body weight were stocked in 44 rectangular 0.2-m2 tanks with 61 L kept under continuous recirculation and water filtration during the night. Shrimp were fed eight times a day, exclusively in feeding trays, for 42 days. At harvest, final shrimp survival, final body weight, daily growth, final yield and feed conversion ratio (FCR) reached 97.0 ± 5.5%, 17.12 ± 1.14 g, 0.23 ± 0.02 g, 448 ± 59 g/m2 and 1.65 ± 0.27, respectively. These growth parameters were not significantly affected by the inclusion of BSFLM. However, a significant reduction in apparent feed intake was detected at the 5% inclusion compared to 3%. In conclusion, dried black soldier fly larvae meal can be safely used in diets for juvenile Litopenaeus vannamei.
