“…Harris and van Bergeijk (Harris and van Bergeijk, 1962) first suggested the lateral line's involvement in near-field sound source localization, and, van Bergeijk later posited that the lateral line and the inner ear should be thought of as parts of an 'acoustico-lateralis' system that could compute sound-source location within the near field (van Bergeijk, 1964). van Bergeijk assumed that the inner ears of fishes could only detect sound pressure (via the swim bladder ear linkage) and discounted their utility in detecting acoustic particle motion.…”

SUMMARYSound-source localization behavior was studied in the plainfin midshipman fish (Porichthys notatus) by making use of the naturally occurring phonotaxis response of gravid females to playback of the maleʼs advertisement call. The observations took place outdoors in a circular concrete tank. A dipole sound projector was placed at the center of the tank and an 80-90Hz tone (the approximate fundamental frequency to the maleʼs advertisement call) was broadcast to gravid females that were released from alternative sites approximately 100cm from the source. The phonotaxic responses of females to the source were recorded, analyzed and compared with the sound field. One release site was approximately along the vibratory axis of the dipole source, and the other was approximately orthogonal to the vibratory axis. The sound field in the tank was fully characterized through measurements of the sound pressure field using hydrophones and acoustic particle motion using an accelerometer. These measurements confirmed that the sound field was a nearly ideal dipole. When released along the dipole vibratory axis, the responding female fish took essentially straight paths to the source. However, when released approximately 90deg to the sourceʼs vibratory axis, the responding females took highly curved paths to the source that were approximately in line with the local particle motion axes. These results indicate that the acoustic cues used by fish during sound-source localization include the axes of particle motion of the local sound field.

“…Furthermore, Van Duren et al (this volume) examined the energy content of a copepod hop and found the energy to dissipate within 0.5 s. Therefore, a velocity gradient will not remain distinct in the £uid at distances in excess of a few millimetres from the passing copepods, or over periods of more than 1^2 s since path creation. In addition, one component of £uid £ow, the pressure wave, transmits from a point source radially and linearly (Harris & van Bergeijk 1962;Tautz 1979). The path of the male to the female, however, was highly convoluted.…”

Within laboratory-induced swarms of the marine copepod Temora longicornis, the male exhibits chemically mediated trail-following behaviour, concluding with £uid mechanical provocation of the mate-capture response.The location and structure of the invisible trail were determined by examining the speci¢c behaviour of the female copepods creating the signal, the response of the male to her signal, and the £uid physics of signal persistence. Using the distance of the mate-tracking male from the ageing trail of the female, we estimated that the molecular di¡usion coe¤cient of the putative pheromonal stimulant was 2.7 Â10 À5 cm 2 s À1 , or 1000 times slower than the di¡usion of momentum. Estimates of signal strength levels, using calculations of di¡usive properties of odour trails and attenuation rates of £uid mechanical signals, were compared to the physiological and behavioural threshold detection levels. Males ¢nd trails because of strong across-plume chemical gradients; males sometimes go the wrong way because of weak along-plume gradients; males lose the trail when the female hops because of signal dilution; and mate-capture behaviour is elicited by suprathreshold £ow signals. The male is stimulated by the female odour to accelerate along the trail to catch up with her, and the boundary layer separating the signal from the chemosensitive receptors along the copepod antennule thins. Di¡usion times, and hence reaction times, shorten and behavioural orientation responses can proceed more quickly. While`perceptive' distance to the odour signal in the trail or the £uid mechanical signal from the female remains within 1^2 body lengths (55 mm), the`reactive' distance between males and females was an order of magnitude larger. Therefore, when nearest-neighbour distances are 5 cm or less, as in swarms of 10 4 copepods m À3 , mating events are facilitated. The strong similarity in the structure of mating trails and vortex tubes (isotropic, millimetre^centimetre scale, 10:1 aspect ratio, 10 s persistence), indicates that these trails are constrained by the same physical forces that in£uence water motion in a low Reynolds number £uid regime, where viscosity limits forces to the molecular scale. The exploratory reaches of mating trails appear inscribed within Kolmogorov eddies and may represent a measure of eddy size. Biologically formed mating trails, however, are distinct in their £ow velocity and chemical composition from common small-scale turbulent features; and mechanoreceptive and chemoreceptive copepods use their senses to discriminate these di¡erences. Zooplankton are not aimless wanderers in a featureless environment. Their ambit is replete with clues that guide them in their e¡orts for survival in the ocean.

“…Fishes possess two systems for particle motion detection, the inner ear and the lateral line (Braun and Coombs, 2000;Braun and Coombs, 2010). Based on his work on the lateral line organs of killifish (Fundulus heteroclitus), van Bergeijk suggested that pressure reception by the inner ear allowed for detection of a sound source but that the lateral line system was responsible for supplying directional information (Harris and Van Bergeijk, 1962;Van Bergeijk, 1967). Years later, the relative contributions of the inner ear and lateral line to particle motion detection and source localization are still not firmly understood.…”

We investigated the roles of the swim bladder and the lateral line system in sound localization behavior by the plainfin midshipman fish (Porichthys notatus). Reproductive female midshipman underwent either surgical deflation of the swim bladder or cryoablation of the lateral line and were then tested in a monopolar sound source localization task. Fish with nominally 'deflated' swim bladders performed similar to sham-deflated controls; however, postexperiment evaluation of swim bladder deflation revealed that a majority of 'deflated' fish (88%, seven of the eight fish) that exhibited positive phonotaxis had partially inflated swim bladders. In total, 95% (21/22) of fish that localized the source had at least partially inflated swim bladders, indicating that pressure reception is likely required for sound source localization. In lateral line experiments, no difference was observed in the proportion of females exhibiting positive phonotaxis with ablated (37%) versus sham-ablated (47%) lateral line systems. These data suggest that the lateral line system is likely not required for sound source localization, although this system may be important for fine-tuning the approach to the sound source. We found that midshipman can solve the 180 deg ambiguity of source direction in the shallow water of our test tank, which is similar to their nesting environment. We also found that the potential directional cues (phase relationship between pressure and particle motion) in shallow water differs from a theoretical free-field. Therefore, the general question of how fish use acoustic pressure cues to solve the 180 deg ambiguity of source direction from the particle motion vector remains unresolved.
