Identifying Sciaenid Critical Spawning Habitats by the Use of Passive Acoustics
Abstract Sounds produced by spawning fishes in Pamlico Sound, North Carolina, have been recorded both under captive conditions and in hydrophone and sonobuoy field surveys. These sounds, produced by males, are species specific, are associated with spawning, and are most likely used for advertisement...
