TLDR
It is demonstrated, using auditory brainstem response (ABR), that at least one additional species, the gulf menhaden (Brevoortia patronus), is able to detect ultrasound, while several other species including the bay anchovy, scaled sardine, and Spanish sardines only detect sounds to about 4 kHz.Abstract:
It has previously been shown that at least one species of fish (the American shad) in the order clupeiforms (herrings, shads, and relatives) is able to detect sounds up to 180 kHz. However, it has not been clear whether other members of this order are also able to detect ultrasound. It is now demonstrated, using auditory brainstem response (ABR), that at least one additional species, the gulf menhaden (Brevoortia patronus), is able to detect ultrasound, while several other species including the bay anchovy (Anchoa mitchilli), scaled sardine (Harengula jaguana), and Spanish sardine (Sardinella aurita) only detect sounds to about 4 kHz. ABR is used to confirm ultrasonic hearing in the American shad. The results suggest that ultrasound detection may be limited to one subfamily of clupeiforms, the Alosinae. It is suggested that ultrasound detection involves the utricle of the inner ear and speculate as to why, despite having similar ear structures, only one group may detect ultrasound.read more

Sources of stress in captivity
TL;DR: In this paper, the authors review many of the potential stressors that may adversely affect animals living in captivity and present a suite of behavioral or physiological responses that will clearly indicate the cause of those responses; rather, it is up to us as managers and caretakers of animals in captivity to evaluate enclosures and husbandry practices to ensure the optimal well-being of animals.

The effects of anthropogenic sources of sound on fishes.
Arthur N. Popper,M.C. Hastings +1 more
TL;DR: The critical literature review concludes that very little is known about effects of pile driving and other anthropogenic sounds on fishes, and that it is not yet possible to extrapolate from one experiment to other signal parameters of the same sound, to other types of sounds, toother effects, or to other species.

Rethinking sound detection by fishes.
Arthur N. Popper,Richard R. Fay +1 more
TL;DR: It is proposed that the term "specialization" be reserved for cases in which a species has some kind of morphological connection or close continuity between the inner ear and an air bubble that affects behavioral sensitivity to sound pressure.

Sound as an Orientation Cue for the Pelagic Larvae of Reef Fishes and Decapod Crustaceans
TL;DR: A diverse series of field experiments including light-trap catches enhanced by replayed reef sound, in situ observations of behaviour and sound-enhanced settlement rate on patch reefs collectively provide a compelling case that sound is used as an orientation and settlement cue for these late larval stages.

Noise-induced stress response and hearing loss in goldfish (Carassius auratus).
TL;DR: Noise exposure did not produce long-term physiological stress responses in goldfish, but a transient spike in plasma cortisol did occur within 10 min of the noise onset, and it took goldfish 14 days to fully recover to control hearing levels.

A comparative study of hearing ability in fishes: the auditory brainstem response approach
TL;DR: Comparison between methods revealed the advantages of this technique: rapid evaluation of hearing in untrained fishes, and no limitations on repeated testing of animals.

Acoustic alarms reduce porpoise mortality
Scott D. Kraus,Andrew J. Read,Andrew R. Solow,Kenneth C. Baldwin,Trevor R. Spradlin,Eric Anderson,John Williamson +6 more
TL;DR: In this paper, the authors describe a field experiment showing that acoustic alarms are effective at reducing the number of deaths of harbour porpoises in sink gill-nets. But acoustic alarms have not been tested in field experiments with sufficient statistical power.

Arthur N. Popper,Richard R. Fay +1 more
TL;DR: Based on the data reviewed in the paper, it is tentatively concluded that the teleost auditory system is well adapted as a temporal analyzer.

A clupeid fish can detect ultrasound
TL;DR: It is reported that at least one species of clupeid fish (herrings and shads), the American shad (Alosa sapidissima), can detect sounds up to 180 kHz and it is speculated that clupeids are able to detect the ultrasonic clicks of one of their major predators, echolocating cetaceans.

Variability in the role of the gasbladder in fish audition.
TL;DR: Hearing in two species (the blue gourami Trichogaster trichopterus, and the oyster toadfish Opsanus tau) without a mechanical linkage is investigated, suggesting that the gasbladder may not serve an auditory enhancement function in teleost fishes that lack mechanical coupling between the gas Bladder and the inner ear.
