The study titled "Evaluation of native macroalgae species of the Southeast U.S. and Caribbean for use in integrated multi-trophic aquaculture (IMTA)" was published in the journal Aquaculture International. Led by scientists at the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science, the study offers new insights into how aquaculture producers can improve sustainability by farming macroalgae species in a complementary system alongside finfish. "With significant interest in the development of marine aquaculture throughout the Southeast U.S.…
