{"data":[{"source":"bio.acousti.ca","id":"58392","topic":"behaviour","value":"Four basic sounds plus combi- nations were identified from the tank recordings when fish were present and were encountered on numerous occasions throughout the study. We classified the basic sounds as two types of pulses (A and B), short bursts, and long bursts, and combinations of short and long bursts (Fig. 1). Mean peak frequencies of the four sound types were less than 39 Hz, while mean durations ranged from 67 ms to 545 ms, depending on sound type (Table 1). Short bursts were similar to the sounds we earlier characterized as \u2018\u2018booms\u2019\u2019 (Clark and Allen, 2018) although the peak frequencies were lower in the tank than in the wild. The short and long bursts along with their combinations are new to the Giant Sea Bass sound repertoire and only occurred during spawning events (the eve and night of spawn verified by fertilized egg collection). None of the four sound types were recorded in the absence of fish during control recordings.","topic_link":"http:\/\/rs.tdwg.org\/ontology\/voc\/SPMInfoItems#Behaviour","info_url":"https:\/\/bio.acousti.ca\/node\/58392"}]}
