A. S. Kane, J. Song, M. B. Halvorsen, D. L. Miller, J. D. Salierno, L. E.
Wysocki, D. Zeddies and A. N. Popper  (2010): Exposure of fish to
high-intensity sonar does not induce acute pathology. J. Fish Biol. 76 (7),
Abstract: This study investigated immediate effects of intense sound
exposure associated with low-frequency (170?320 Hz) or with mid-frequency
(2·8?3·8 kHz) sonars on caged rainbow trout Oncorhynchus mykiss, channel
catfish Ictalurus punctatus and hybrid sunfish Lepomis sp. in Seneca Lake,
New York, U.S.A. This study focused on potential effects on inner ear
tissues using scanning electron microscopy and on non-auditory tissues using
gross and histopathology. Fishes were exposed to low-frequency sounds for
324 or 628 s with a received peak signal level of 193 dB re 1 µPa (root mean
square, rms) or to mid-frequency sounds for 15 s with a received peak signal
level of 210 dB re 1 µPa (rms). Although a variety of clinical observations
from various tissues and organ systems were described, no exposure-related
pathologies were observed. This study represents the first investigation of
the effects of high-intensity sonar on fish tissues in vivo. Data from this
study indicate that exposure to low and midfrequency sonars, as described in
this report, might not have acute effects on fish tissues.

K. S. Boyle, T. E. Cox (2010): Courtship and spawning sounds in bird wrasse
Gomphosus varius and saddle wrasse Thalassoma duperrey. J. Fish Biol. 75
(10), 2670-2681
Abstract: Acoustic signals from the bird wrasse Gomphosus varius and saddle
wrasse Thalassoma duperrey were recorded on coral reefs in Hawaii. Terminal
phase males in both species emit two types of pulse trains (type I and type
II). Type I pulses were produced during spawning and courtship, while type
II pulses were associated only with courtship behaviours. Gomphosus varius
type I pulses were of lower frequency than T. duperrey type I pulses (271 v.
840 Hz) and were of narrower band. Discriminant function analyses revealed
interspecific differences between type I pulse trains and individual pulses
of both types. This study is the first documentation of courtship and
spawning sounds in sympatric labrids and shows divergence in acoustic

B. M. Casper, D. A. Mann (2010): Field hearing measurements of the Atlantic
sharpnose shark Rhizoprionodon terraenovae. J. Fish Biol. 75 (10),
Abstract: Field measurements of hearing thresholds were obtained from the
Atlantic sharpnose shark Rhizoprionodon terraenovae using the auditory
evoked potential method (AEP). The fish had most sensitive hearing at 20 Hz,
the lowest frequency tested, with decreasing sensitivity at higher
frequencies. Hearing thresholds were lower than AEP thresholds previously
measured for the nurse shark Ginglymostoma cirratum and yellow stingray
Urobatis jamaicensis at frequencies <200 Hz, and similar at 200 Hz and
above. Rhizoprionodon terraenovae represents the closest comparison in terms
of pelagic lifestyle to the sharks which have been observed in acoustic
field attraction experiments. The sound pressure levels that would be
equivalent to the particle acceleration thresholds of R. terraenovae were
much higher than the sound levels which attracted closely related sharks
suggesting a discrepancy between the hearing threshold experiments and the
field attraction experiments.

S. Malavasi, C. Valerio, P. Torricelli (2009): Courtship sounds and
associated behaviours in the Canestrini's goby Pomatoschistus canestrinii.
J. Fish Biol. 75 (7), 1883-1887.
Abstract: Courtships sounds and associated behaviours were recorded in the
Canestrini's goby Pomatoschistus canestrinii using a simultaneous
video?acoustic system: the male exhibited a display composed of both a
visual (rapid head movements) and an acoustic component (thump sound), and
its intensity was positively associated with that of a female visual

(2009): Agonistic sounds in the skunk clownfish Amphiprion akallopisos:
size-related variation in acoustic features. J. Fish Biol. 75 (4), 908-916.
Abstract: Fourteen individuals of the skunk clownfish Amphiprion akallopisos
of different sizes and of different sexual status (non-breeder, male or
female) were analysed for four acoustic features. Dominant frequency and
pulse duration were highly correlated with standard length (r = 0·97), and
were not related to sex. Both the dominant frequency and pulse duration were
signals conveying information related to the size of the emitter, which
implies that these sound characteristics could be useful in assessing size
of conspecifics.
