“…Our species-specific spectral analyses are in agreement with the sound identifications based on captive or in situ recordings of these fishes by other investigators. The species-specific nature of these calls have been previously described via spectrograms in other studies: Fish and Mowbray (1970) described the calls and provided spectrograms of silver perch, weakfish, and red drum recorded in captivity; Guest and Lasswell (1978) showed a spectrogram of red drum recorded in captivity; Mok and Gilmore (1983) characterized the calls of silver perch and spotted seatrout in situ; Connaughton and Taylor (1996) and Connaughton et al (1997Connaughton et al ( , 2000 described the pattern and mechanism of sound production by weakfish in captivity; Perkins (2001) described the drumming sound of weakfish in situ and distinguished it from the chattering sounds initially described by Fish and Mowbray (1970) as being produced by weakfish but subsequently confirmed by Mann et al (1997) and Sprague and Luczkovich (2001) as being produced by striped cusk-eels Ophidion marginatum; Gilmore (2003) described the spectral characteristics of spotted seatrout calls in situ; and Sprague et al (2000) described the spectrograms, oscillograms, and average power spectra of the sciaenids studied here used the same captive recordings used in this paper, but different in situ recordings).…”

“…Sound production associated with spawning is likely to be an advertisement call produced by the males (Connaughton and Taylor 1996) in a manner similar to that used by Atlantic cod Gadus morhua to attract females to group spawning aggregations (Nordeide and Folstad 2000) or by oyster toadfish Opsanus tau to attract females to the territories of individual males (Fine and Thorson 2008, this issue). Additional studies of in situ spawning behavior in these fish are needed to determine the function of sound production in spawning.…”

“…Their sounds are used in communication during reproduction and aggressive encounters and as disturbance calls (Fish and Mowbray 1970;Guest and Lasswell 1978;Connaughton and Taylor 1996;Gilmore 2003). Worldwide, there are over 280 species of sciaenids and most of them produce sounds, although only a few species' sounds have been thoroughly documented (Fish and Mowbray 1970).…”

Abstract.-Sounds produced by spawning fishes in Pamlico Sound, North Carolina, have been recorded both under captive conditions and in hydrophone and sonobuoy field surveys. These sounds, produced by males, are species specific, are associated with spawning, and are most likely used for advertisement to attract females. Sounds can be discriminated by use of spectral analysis (oscillograms and spectrograms) of recordings, and the peak frequencies produced by each species can be correlated with species and fish size. Sonobuoys were used for passive acoustic surveys, which were ''sound truthed'' from recordings of captive fishes to determine the timing and location of spawning sites for four species in the family Sciaenidae: red drum Sciaenops ocellatus, spotted seatrout Cynoscion nebulosus, weakfish C. regalis, and silver perch Bairdiella chrysoura. During May-September 1998, sounds were first detected in the early evening, increased in loudness after sunset, and ended by sunrise. Weakfish and silver perch were heard predominantly at inlet locations in May and June, whereas spotted seatrout (peak drumming in July) and red drum (peak drumming in September) were heard predominantly at lower-salinity river mouth locations in western Pamlico Sound. Passive acoustic surveys can be used to determine critical spawning habitats of sciaenid fishes; such surveys have revealed interesting insights into fish behavior and should be integrated into ocean observing systems.

“…Las corvinas pertenecen a la familia Sciaenidae, se les conoce como roncadores debido a los sonidos que producen durante el cortejo de reproducción (Connaughton y Taylor, 1996;Lagárdere y Marianis, 2006), y se distribuyen en las regiones templadas y tropicales de todo el mundo (Jiménez et al, 2005).…”

Peces juveniles de corvina aguada, Cynoscion squamipinnis, obtenidos a partir de desoves espontáneos en cautiverio fueron engordados por 355 días en la Estación de Biología Marina Juan Bertoglia Richards (Costa Rica). Ciento cincuenta y dos peces fueron sembrados en tanques de cuatro toneladas a una biomasa total de 82 g m-3, y alimentados con una dieta de 50% proteína, 17.5% carbohidratos, 11.8% lípidos, 16% ceniza y 5% humedad. El oxígeno disuelto fue de 7.12±1.13 mg L-1 (5.68 - 9.13 mg L-1), la salinidad de 31.92±1.65 ups (29.84 - 34.71 ups), y la temperatura de 27.54±0.63°C (26.50 - 28.60°C), condiciones similares a las del Golfo de Nicoya. El peso inicial promedio fue de 3.77±1.15 g (0.3 - 6.2 g). El peso promedio final fue de 132.60±32.96 g (78.5 - 219.3 g). El crecimiento (C) fue de 128.83 g, con una tasa de crecimiento (TC) de 0.36 g d-1, y una tasa específica de crecimiento (TEC) de 1.00 % PC d-1. La tasa de crecimiento relativa (TCR) fue de 0.0053 g g-1 d-1. El factor de conversión alimenticia (FCA) durante todo el periodo fue de 1.8±0.4. La corvina aguada tuvo un crecimiento menor al de otras corvinas, mostró un comportamiento tranquilo, aceptó la dieta peletizada y fue fácil de manipular, por lo que es candidata para la maricultura.

“…Weakfish are an important commercial and recreational fish in the estuaries and coastal waters of the eastern USA. Male weakfish produce a sound known as a "purr" during spawning periods [1,2] using sonic muscles and their swim bladders [4,5]. These sounds have been used [6,7,3] to identify weakfish spawning areas and critical habitats for the species.…”

Modeling fish aggregation sounds in very shallow water to estimate numbers of calling fish in aggregations

A model was constructed to predict sounds produced by aggregations of calling fish and relate aggregation sound levels measured by a single receiver to the numbers of calling fish in the aggregations. The model uses the finite difference time domain (FDTD) method to compute the propagation of the pulsed sounds of calling individuals to the receiver. In order to establish averages and uncertainties of aggregation sound pressure levels, the model uses an ensemble of Monte Carlo-generated virtual aggregations with calling fish at randomized locations that vary horizontally in a uniform random distribution and vertically in a beta distribution. Ensembles of aggregations were created for different aggregation population sizes and bottom depths. The predicted aggregation sound levels increased with aggregation population size for the three bottom depths considered. The aggregation sound pressure levels for all depths fell along the same curve when they were plotted vs. fish volume-specific density. Though preliminary, these findings suggest that it may be possible to use this model to predict the number of calling fish in an aggregation from single hydrophone recordings.
