A comparative study of hearing ability in fishes: the auditory brainstem response approach
Comparison between methods revealed the advantages of this technique: rapid evaluation of hearing in untrained fishes, and no limitations on repeated testing of animals.
Ship noise and cortisol secretion in European freshwater fishes
Sound-Generating Mechanisms in Fishes: A Unique Diversity in Vertebrates
Fishes have evolved the largest diversity of sonic organs among vertebrates and sound-generating mechanisms may be similarly developed in males and females (croaking gourami) or sexually dimorphic, in which case they are always better developed in females.
The ontogenetic development of auditory sensitivity, vocalization and acoustic communication in the labyrinth fish Trichopsis vittata
It is indicated that auditory sensitivity develops prior to the ability to vocalize and that vocalization occurs prior toThe ability to communicate acoustically.
Auditory evoked potential audiometry in fish
The AEP-technique was frequently used to study the effects of high sound/noise levels on hearing in particular by measuring the temporary threshold shifts after exposure to various noise types (white noise, pure tones and anthropogenic noises) and was successfully utilized to study acoustic communication.

Comparisons between the habitat noise types presented here and prior data on auditory masking indicate that fishes with enhanced hearing abilities are only moderately masked in stagnant, quiet habitats, whereas they would be considerably masked in fast-flowing habitats.
Effects of ambient and boat noise on hearing and communication in three fish species living in a marine protected area (Miramare, Italy).

The fine structure of the TT reveals that contractions most likely prevent transmission of swimbladder vibrations to the inner ear via the Weberian ossicles during vocalization, suggesting faster contraction properties and greater resistence to fatigue compared with sonic muscles.

This study provides the first evidence that fishes' auditory sensitivity can be impaired by ship noise and that acoustic communication, which is essential during agonistic encounters and mate attraction, might be restricted in coastal environments altered by human activity.
Diversity in noise-induced temporary hearing loss in otophysine fishes.
The results indicate that hearing specialists are affected differently by noise exposure and that acoustic communication might be restricted in noisy habitats.
