摘要1995-1997年7 - 10月，在格鲁吉亚沿岸沿着进行了红眼石首鱼产卵场的被动声采样。在人工饲养条件下观察产卵的红鼓，以确定与产卵相关的声音水平。1997年，每周用一个移动的水听器对一个已知的红鼓鱼产卵场进行取样，并在1997年9月23日至10月2日期间连续使用一个遥控水听器进行取样。现场和坦克的观察表明，红鼓男性使呼叫与四个或更少的脉冲，每个呼叫没有相关的产卵。然而，呼叫组成的至少8个脉冲/呼叫只发生之前产卵。1995年和1996年，在多博伊、阿尔塔马哈、圣西蒙和圣安德鲁海峡以及沿着格鲁吉亚海岸的补充地点定期取样的台站共进行了372次水听器观测。只有一个近岸产卵场被发现，它被发现在坎伯兰湾口的圣玛丽海峡。持续时间的高峰红鼓声产品.
Abstract Passive acoustic sampling to locate spawning sites of red drum Sciaenops ocellatus was conducted along the Georgia coast during July-October 1995-1997. Spawning red drum were observed in captivity to determine the level of sound associated with spawning. In 1997, a known red drum spawning site was sampled weekly with a mobile hydrophone and continuously with a remote hydrophone deployed from 23 September to 2 October 1997. Both field and tank observations indicated that red drum males make calls with four or fewer pulses per call without associated spawning. However, calls consisting of at least 8 pulses/call occurred only prior to spawning. In 1995 and 1996, a total of 372 hydrophone observations were made at regularly sampled stations in Doboy, Altamaha, St. Simon's, and St. Andrew sounds and at supplemental locations along the Georgia coast. Only one nearshore spawning site was located; it was found in St. Mary's channel at the mouth of Cumberland Sound. Duration of peak red drum sound product...
