Sablefish sounds, named rasps, were recorded at two captive facilities in British Columbia and Washington State. Rasps consisted of highly variable broadband trains of 2 to 336 ticks that lasted between 74 and 10 500 ms. The 260 rasps that were measured contained frequencies between 344 and 34 000 Hz with an average peak frequency of 3409 Hz. The frequency structure of ticks within rasps was highly variable and included both positive and negative trends. This finding makes sablefish one of the few deep-sea fish for which sounds have been validated and described. The documentation of sablefish sounds will enable the use of passive acoustic monitoring methods in fisheries and ecological studies of this commercially important deep-sea fish.

In order to identify fish sounds in British Columbia soundscapes, we need catalogues of validated fish sounds from Pacific species. These catalogues will help in comparing validated examples to unknown sounds found in long-term autonomous recordings. In addition, it is important that the sounds be described quantitatively for accurate identification and comparison. Our goal is to contribute to building such catalogues and to fill knowledge gaps in fish acoustic behaviour to support studies on the impact of anthropogenic noise on Pacific fishes. Since distinguishing sound sources in the ocean is extremely difficult, we are collaborating with aquaria, marine science centers and ocean-based aquaculture facilities to monitor, audition and record the acoustic behaviour of captive and semi-captive fish species. To date, we have acquired over 3,000 hours of recordings in these conditions. Sounds that we have already validated include Arctic cod (Boreogadus saida), walleye pollock (Gadus chalcogrammus), and grunt sculpin (Rhamphocottus richardsonii) vocalizations. Here, we will present a description of these newly validated sounds.
