Use of Passive Acoustics for Assessing Behavioral Interactions in Individual Toadfish

Most passive acoustics studies focus on daily and seasonal timing and location of choruses of calling fish, particularly sciaenids. Because male toadfish Opsanus spp. are stationary for extended periods, it is possible to extract detailed information about their calls and interactions, making them a powerful model for passive acoustics studies on commercially important species. Toadfishes of both sexes produce a short, pulsatile agonistic grunt,...
