The sound properties produced by the white-edged rockfish (Sebastes taczanowskii Steindachner, 1880) were compared with the body size. We conducted a tank experiment to compare the sound properties with body length, which ranged from 12.4 to 19.8 cm. Sound production was composed of pulses with a duration of 0.010-0.022 s and a peak frequency of 400-1000 Hz. Peak frequency decreased with fish and swim bladder size and pulse duration. The relationship between sound properties and body size may be useful for estimating the body length of the target species by using passive acoustic monitoring.
对白边岩鱼（Sebastes taczanowskii Steindachner，1880）产生的声音特性与鱼体大小进行了比较。我们进行了一项水槽实验，以比较声音特性与体长的关系，体长范围为12.4至19.8厘米。发声由持续时间为0.010 - 0.022秒、峰值频率为400 - 1000赫兹的脉冲组成。峰值频率随鱼体和鱼鳔大小以及脉冲持续时间的增加而降低。声音特性与鱼体大小之间的关系可能有助于通过被动声学监测来估计目标物种的体长。
