Effect of long-term feeding of a diet containing defatted black soldier fly Hermetia illucens larvae meal on the growth of olive flounder Paralichthys olivaceus

Key Points

• To investigate the effect of a diet containing defatted black soldier fly larvae meal on the growth of olive flounder.
• Feeding trial conducted for 14 months using two diet groups: control (FM) and 10% black soldier fly larvae meal (BSF10).
• Fish were juvenile olive flounders with an initial weight of 3.1 g.
• Growth measurements included weight and length comparison between groups.
• The BSF10 group showed significantly greater weight and length compared to the FM group.
• No significant decline in feed efficiency was observed in the BSF10 group.
• Long-term substitution of fishmeal with 10% black soldier fly larvae meal did not negatively impact flounder growth.
