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.

Due to the extreme distance that sounds can travel through water, many marine species rely on the soundscape for auditory information regarding predator or prey locations, communication, and habitat selection. These species not only take advantage of the prevailing sounds but also contribute to the soundscape through their own vocalizations. Certain sounds have been shown to have negative effects on marine species, resulting in disrupted communication and unbalanced predator-prey interactions. Unfortunately, the vast majority of soundscape studies are biased towards marine mammals, and only recently has attention been directed towards the potential repercussions for fishes. In an attempt to determine the implications that changes to the soundscape may have on the fishes, a meta-analysis was conducted focusing primarily on the role that anthropogenic noises may play in altering fish behavior and physiology. The review identified 3,174 potentially relevant papers of which were 27 used. The analysis indicates that anthropogenic noise has an adverse effect on marine and freshwater fish behavior and physiology. These findings suggest that although certain species may be more susceptible to anthropogenic noise than others, the vast majority of fish have the potential to be negatively affected by noise pollution.

The ecological importance of the freshwater soundscape is just beginning to be recognized by society. Scientists are beginning to apply Passive Acoustic Monitoring (PAM) methods that are well established in marine systems to freshwater systems to map spatial and temporal patterns of behaviors associated with fish sounds as well as noise impacts on them. Unfortunately, these efforts are greatly hampered by a critical lack of data on the sources of sounds that make up the soundscape of freshwater habitats. A review of the literature finds that only 87 species have been reported to produce sounds in North America and Europe over the last 200 years, accounting for 5\% of the known freshwater fish diversity. The problem is exacerbated by the general failure of researchers to report the detailed statistical descriptions of fish sound characteristics that are necessary to develop PAM programs. We suggest that publishers and editors should do more to encourage reporting of statistical properties of fish sounds. In addition, we call for research, academic, and government agencies to develop regional libraries of fish sounds to aid in PAM and anthropogenic noise impact studies.

Noise from this shipping traffic can lead to acoustic masking, reducing the ability of marine animals to detect and use biologically important sounds. Vessel-slow down may be an alternative mitigation option in regions where re-routing shipping corridors to avoid important habitat for fish and marine mammals is not possible. We investigated the potential relief in masking from a 10 knot speed reduction of container and cruise ships. Based on ambient sound measurements and real shipping data, the percentage reduction in the available listening space for fish as a container or cruise ship passes under varying speeds and ambient sound conditions was shown. The mitigation effects from slower vessels (travelling at 15 knots compared to 25 knots), in terms of auditory masking, was equal between ambient sound conditions, but not equal between the type of vessel. Slowing vessels led to a substantial decrease in the listening space reductions, with the amount of reduction varying by distance away from vessels. Vessel slowdown through sensitive habitat could be an effective mitigation strategy for reducing the extent of auditory masking.

We assess the impact of recreational boat traffic on sensitive habitats in the Western Mediterranean using passive acoustics. We compared underwater sounds in three regulated mooring locations vs a pristine location; and temporal differences in the pristine location vs the nearest mooring between high and low touristic seasons. We measured the number of pulses/minute, fish pulse patterns, and percentage of boat noise occurrence and its relative average power level. At the pristine location, the call rates and their complexity were significantly higher and the motorboat noise was significantly lower. The temporal trend of biophonic sounds decreased significantly in the pristine location. In contrast, in the mooring sites, the motorboat noise decreased significantly and the fish calls remained at low levels in both seasons. In conclusion, motorboat noise negatively affects the complexity of the fish assemblages but could be conditioned to their historic uses.

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.

Sound production in fish has been documented; however, the diversity of species that create sound is not fully understood. Pacific salmon (Oncorhynchus spp.) are ecologically, economically, and culturally important in the northeast Pacific. Recent declines in specific species and stocks have increased their public interest. Other species from the family Salmonidae produce sounds, but there is little evidence of any species of Pacific salmon producing sounds. Recording salmon in the wild would be difficult but local hatcheries allow for a unique opportunity to listen for salmon sounds in a semi-natural environment. Chinook salmon (O. tshawytscha), pink salmon (O. gorbuscha), and coho salmon (O. kisutch) were recorded using two stationary acoustic recorders that were deployed at a salmon hatchery in Qualicum beach Vancouver Island, British Columbia, for three consecutive weeks in September and October 2017. Audio files were collected in 5 minute subsections and examined for salmon sounds. Here, we present spectrograms and time-frequency composition of potential sounds found for Chinook, pink, and coho salmon. All sounds were then compared to sounds produced by other soniferous fish and to the hearing range of Pacific salmon.
