Story summary

University of Miami researchers, funded with over $320,000 in grants from Florida Sea Grant and Hinkley Center, are testing black soldier fly larvae to convert beached sargassum into aquaculture feed and fertilizer.
Kitchen-fed larvae reached a protein share of 56.5%.
Mixed-diet larvae achieved a fat share of 47.9% of dried weight and survived 94-99% for 15 days.
Researchers say sargassum trials, arsenic testing, and commercial scaling are needed.
