Journal of the World Aquaculture Society, 56(3), e70024. https://doi.org/10.1111/jwas.70024 Globally, the marine aquarium trade represents a $2.15 billion industry, but it relies heavily on wild-captured rather than cultured fish species. In many regions of the world, this is not a sustainable practice. Therefore, aquaculture practices aimed at high value marine aquarium species should be developed to relieve pressures on natural populations. In Hawai’i, the Potter‘s angelfish (Centropyge potteri) is endemic and in the past it has been widely harvested for the aquarium trade. Regulations currently prohibit the harvest of this species. This study is the first to present a detailed description of aquaculture techniques for C. Potteri. The authors provide important foundational data on larval growth and survival and demonstrate how the refinement of feeding protocols can improve survival rates to settlement. They note that egg and larval development closely resemble other Centropyge species, and captive spawning was shown to be successful and follow lunar cycles. The most vulnerable stages for this species were during feed transition, particularly when shifting to newly hatched Artemia and dry feeds. Success relied on coninuous feeding of live algae and copepods through settlement, and rearing in larger tanks was found to be the most effective at improving survival. Overall, results from this study highlight diet composition and timing, tank management, and environmental stability as key factors for successful larval rearing. Aquaculture development for this species is critical, and this work advances the technology needed for a shift away from wild harvest of Potter’s angelfish to aquaculture as a potential means of supplying the aquarium trade. • Maulu, S., Eynon, B., Abarra, S., Rawling, M., & Merrifield, D. L. (2025). Black soldier fly, Hermetia illucens, larvae meal improves intestinal health and growth performance of Nile tilapia, Oreochromis niloticus, juveniles. Journal of the World Aquaculture Society, 56(3), e70035. https://doi.org/10.1111/ jwas.70035 Despite supply chain and large-scale production challenges, insect meal is becoming more widespread as aquaculture feed ingredient. This study contributes to our current understanding of this ingredient by exploring its use for producing tilapia. The authors specifically evaluate black soldier fly (BSF) larvae, Hermetia illucens, meal and determined the impacts on growth and health of Nile tilapia. The study included diets consisting of three different levels of defatted BSF larvae meal (0% (control), 20%, and 40%) and fish were fed these diets for 5 weeks in a recirculating aquaculture system (RAS). The findings showed that with increasing levels of BSF larvae meal in the diet there was a significant (p < 0.05) increase in final body weight, weight gain, specific growth rate (SGR), protein efficiency ratio (PER), and feed conversion ratio (FCR). Furthermore, histological improvements were observed in the intestine of fish fed diets containing BSF larvae meal. There were no notable changes in the expression of chitin digestion or immune-related genes, but expression was upregulated for the peptide transporter Slc15a1a in fish fed the diet containing 40% BSF meal. Overall, the study supports the conclusion that BSF larvae meal would be an effective alternative protein source for juvenile Nile tilapia and can enhance growth, feed utilization, and intestinal health. The short duration of this study may not represent the longterm effects of feeding this ingredient; therefore, further research should address this.
