The ability of elasmobranchs to detect and use sound cues has been heavily debated in previous research and has only recently received revived attention. To properly understand the importance of so...

Abstract Zebrafish are a critical model species for auditory research not only because of the availability of numerous mutant strains but also because they belong to the Ostariophysans, a group with well-developed hearing specializations, and like all teleosts, they have the ability to regenerate hair cells after extensive damage. Zebrafish also add hair cells throughout life as they grow. This chapter focuses on what is known about the function of the auditory system of zebrafish and how the ge...

Abstract Salmon farming is one of Canada's fastest growing industries and contributes to Canada's economy as well as creating jobs in rural areas; however, the industry is challenged by the need to balance production economics against environmental impacts. While Atlantic salmon ( Salmo salar ) are the most commonly farmed species on the west coast of Canada, Chinook salmon ( Oncorhynchus tshawytscha ) are a valuable alternative, as they fill a niche market and generate reduced environmental con...

Hearing ability is well studied across teleost fishes in general, and vertebrates more broadly, but little is known about sound detection abilities of lampreys (Petromyzontiformes), a basal extant ...

There is increasing concern about the effect of underwater noise on fish due to rising levels of anthropogenic noise. We performed experiments on the black bullhead (Ameiurus melas), a species with...

In recent years, the effects of anthropogenic noise on freshwater fish has been of increasing interest for fishery managers due to rising levels of this background noise. While it is clear that anthropogenic noise can have important impacts on mammals and marine fish, much less is known about these effects in fresh water. The influence of anthropogenic noise on freshwater fish can be quantified using the same methods as with marine species — through measuring changes in behavioural and physiolog...

Two sounds associated with spawning lake trout (Salvelinus namaycush) in lakes Huron and Champlain were characterized by comparing sound recordings with behavioral data collected using acoustic telemetry and video. These sounds were named “growls” and “snaps” and were heard on lake trout spawning reefs, but not on a nonspawning reef, and were more common at night than during the day. Growls also occurred more often during the spawning period than the prespawning period, while the trend for snaps...

Low levels of heterozygosity can have detrimental effects on life history and growth characteristics of organisms but more subtle effects such as those on trade-offs of expensive tissues and morphological laterality, especially of the brain, have not been explicitly tested. The objective of the current study was to investigate how estimated differences in heterozygosity may potentially affect brain-to-body trade-offs and to explore how these heterozygosity differences may affect differential bra...

Whole-brain responses to sound are easily measured through auditory evoked potentials (AEP), but it is unclear how differences in experimental parameters affect these responses. The effect of varying parameters is especially unclear in fish studies, the majority of which use simple sound types and then extrapolate to natural conditions. The current study investigated AEPs in goldfish (Carassius auratus) using sounds of different durations (5, 10, and 20 ms) and frequencies (200, 500, 600 and 700...
