摘要： Chinese bahaba (Bahaba taipingensis) is a critically endangered fish species, which can produce sounds like other Sciaenidae species. In this study, sounds produced by sexually mature Chinese bahaba were recorded during the reproduction season for the first time. Two distinct types of sounds were observed during the reproduction season, termed as single drum and fast drum trains calls. Single drum callings occurred as a series of trains with rapid pulses, while fast drum trains callings were mainly made of a single signal. The single drum and fast drum trains had a peak frequency of 77.8 +/- 16.2 Hz and 79.1 +/- 8.7 Hz, respectively. Statistical analysis suggested significant differences in -3 dB bandwidth, signal duration, and root-mean-square sound pressure levels, except for peak frequency (p < 0.05) between single drum and fast drum trains sounds. Single drum occurred mainly before dawn (period range from 0:00 to 6:00 am) and less frequently after dusk (18:00-24:00 pm), and the fast drum trains occurred after dawn (6:00 am to 12:00 pm) and dusk (18:00 pm to 24:00 pm). Considering the abundance of Chinese bahaba has significantly declined, passive acoustic monitoring provides a non-invasive and low-cost effective tool to monitor sound production during reproduction season, which may help to facilitate aquaculture management and fishery population conservation in the future.
