![]() ![]() These marine managed areas have focused on reproductive seasons through seasonal closures. Yet, impacts of protecting fish spawning aggregations with seasonal marine managed areas or market bans remain largely unknown.Ī "call" of the wild inspired researchers from Florida Atlantic University's Harbor Branch Oceanographic Institute to follow and record grouper mating sounds at three marine managed areas off the west coast of Puerto Rico in the United States Caribbean.įor the study, researchers used passive acoustics to locate spawning aggregations of two commercially important species - the Nassau (Epinephelus striatus) and red hind (Epinephelus guttatus) groupers - to determine temporal patterns in their reproductive behaviors as well as habitat use. Recent evidence suggests that some reproductive times are extending beyond months and locations for which the marine managed areas were established. ![]() ![]() Although protective measures are in place through marine managed areas, these management zone boundaries may fail to fully encompass fish migration paths and chronological variability in fish spawning aggregations, especially for threatened species. ![]()
