​Giant Sea Bass (GSB), Stereolepis gigas, is the largest marine bony fish off the coast of California, an apex predator, and is currently classified as critically endangered by IUCN Red List. Despite recent studies on GSB, there is no documentation of their spawning and related reproductive behaviors in their natural environment due to their depressed population size. Previous studies have shown GSB capable of producing a variety of sounds (many sounding like a “boom”). Past studies have observed that the closer in proximity you are to a GSB spawning aggregation the louder and more numerous GSB sounds are heard. In these spawning aggregations, “booms” have been observed to be linked with antagonistic behaviors between GSB males, indicating that sound production is most likely part of spawning. In the summer of 2019 novel reproductive sounds labeled “snares” & “bursts” were recorded during successful spawning events of captive GSB. These novel sounds have only been observed and recorded during spawning. Using Raven Pro we examined audio samples gathered in the summers of 2014, 2015, and 2019 and identified “snare” and “burst” sounds recorded at GSB spawning aggregations. We then tested recorded when these sounds occurred, to see if they occurred during time of spawning. We hypothesize that GSB vocalization occurs frequently during spawning and is used in combination with courtship behaviors to signal reproduction readiness. I argue that by identifying these behaviors, we will be able to verify GSB spawning when these auditory behaviors are observed during their period of spawning.
