“…In aquaculture systems, the lower frequency ranges (25 to 1000 Hz) are generally louder than higher frequency regions (Bart et al 2001), and recordings of the aquaculture tank in our study confirm this. Without recording the natural environment, it is difficult to directly compare what sound characteristics and levels both groups of fish were exposed to prior to auditory testing.…”

“…Fish in hatchery and culture settings are exposed to relatively loud ambient noise levels, particularly in recirculating systems, due to the use of machinery, water circulation and air supply. In closed environments, fish are unable to escape from areas with loud noise, and thus are exposed to chronic elevated sound levels that are well within their hearing ranges (Wysocki et al 2007), often 20 to 50 dB re 1 µPa higher than in their natural habitats (Bart et al 2001). Sound levels and frequencies recorded in commercial settings range from 125 to 135 dB re 1 µPa at 25−1000 Hz, and from 100 to 115 dB re 1 µPa at 1−2 kHz (Bart et al 2001), but have been recorded as high as 153 (Bart et al 2001) and 160 dB re 1 µPa (Clark et al 1996).…”

A growing body of evidence suggests that larval fish use sound as an orientation cue to remotely locate suitable settlement habitats. Several theoretical models have used hearing thresholds to estimate the distance at which fish larvae can detect reefs. However, researchers have often measured hearing thresholds from fish raised in aquaculture environments, or held them in closed-system tanks once caught, where equipment can significantly increase the noise levels in the tanks. The possibility arises that exposure to such noise negatively affects the hearing ability of the fish held there, such that distances predicted from these studies may be underestimated. The objective of this study was to compare the hearing ability of wild versus aquacultured snapper Pagrus auratus using auditory evoked potentials. Juvenile snapper from aquaculture tanks had significantly higher hearing thresholds at 100, 200 and 400 Hz than wild snapper. A controlled noise-exposure experiment, where snapper were ex posed for 2 wk to low-intensity noise at 120 dB re 1 µPa, confirmed these results. When plotted using an extended reef-based model, the distance at which aquaculture-raised snapper are predicted to detect a particular reef was half of that found for their wild counterparts. Clearly, the acoustic history of experimental subjects is an important consideration when using hearing thresholds to make ecological estimations, such as the distance at which larvae could detect reefs.

“…A relatively old study, in which the acoustics of the experiments were poorly controlled and calibrated, suggested lower egg viability and reduced larval growth rates in noisy fish tanks compared to more quiet control tanks [35]. A more recent and better study on rainbow trout (Oncorhynchus mykiss), exposed to realistic noise levels for fish tanks in an aquaculture facility [36] showed no impact on growth, survival, or susceptibility to disease, even over nine months of exposure [31]. However, given the very limited number of species investigated, it is not clear whether one can extrapolate from captive rainbow trout to other species that may differ in hearing ability and in the extent they depend on sound for natural activities.…”

“…Over the last 2 decades, an increasing amount of evidence has shown that underwater sounds generated by human activities affect several types of responses in fish (Myrberg 1980, Engås et al 1996, Bart et al 2001, Smith et al 2004, Popper et al 2005, Sandstrom et al 2005. Nevertheless, little is known to date on how noise pollution can affect the fitness of fish.…”

The effect of boat noise on the behaviour of bluefin tuna Thunnus thynnus was investigated\ud in the Egadi Islands, Sicily, during spring 2005 using a fixed tuna trap set near shipping routes.\ud Tuna behaviour was observed when exposed to both natural ambient sound and sound generated by\ud hydrofoil passenger ferries, small boats and large car ferries. Acoustical and behavioural analyses\ud were conducted with and without extraneous sound to define a list of behavioural categories. Each\ud vessel produced different engine sounds with regard to their composition and bandwidth, and all\ud were distinctly different from ambient sound levels. In the absence of boat noise, tuna assumed a concentrated\ud coordinated school structure with unidirectional swimming and without a precise shape.\ud When a car ferry approached, tuna changed swimming direction and increased their vertical movement\ud toward surface or bottom; the school exhibited an unconcentrated structure and uncoordinated\ud swimming behaviour. Hydrofoils appeared to elicit a similar response, but for shorter periods. Agonistic\ud behaviour was more evident when exposed to sounds from outboard motors of small boats. This\ud study showed that local noise pollution generated by boats produced behavioural deviations in tuna\ud schools. Schooling enhances tuna homing accuracy during their spawning migration, and an alteration\ud in schooling behaviour can affect the accuracy of their migration to spawning and feeding\ud grounds
