UrduGroupers produce distinct sounds associated with courtship, territoriality or reproduction. An autonomous mobile wave glider and passive acoustics were deployed to survey two marine protected areas on the western shelf of Puerto-Rico to locate spawning aggregations of two commercially important species – the Nassau and red hind groupers. Findings show these sites are critical habitat for both species and multiple previously unknown grouper species, which highlight the importance of expanding existing seasonal regulations.

Boom! Detecting Gregarious Goliath Groupers Using Their Low-frequency Pulse Sounds
From growls to booms, whales, fish and crustaceans all produce sounds. Selecting the gregarious Goliath grouper, researchers deployed a novel automated detector and localization model to find underwater marine organisms using their low-frequency pulse sounds.
