本研究的目的是建立一种被动声学调查方案，以确定香鱼的产卵栖息地。通过对圈养鱼的录音和特定物种求偶声的现场录音的比较，在北卡罗来纳州帕姆利科湾确定了红鼓鱼、弱鱼、斑点海鳟鱼和银鲈的产卵区域。Sciaenid的声音记录使用从船上部署的便携式水听器或定时操作的声纳浮标。弱鱼和银鲈交配声的响度与远洋海葵类卵的丰度密切相关，表明这些区域被用于产卵。声纳浮标记录显示，弱鱼只在靠近入海口的高盐度栖息地产卵，斑点海鳟主要在靠近河口的低盐度区域产卵，银鲈在高盐度和低盐度区域产卵，红鼓鱼最常在低盐度区域产卵，但只在9月产卵。交配的声音……
The goal of this study was to develop a passive acoustic survey protocol to identify spawning habitats of sciaenid fishes. Based on comparisons of recordings of captive‐fish and field recordings of species‐specific courtship sounds, spawning areas of red drum, weakfish, spotted sea trout, and silver perch (Family Sciaenidae) have been identified in Pamlico Sound, NC. Sciaenid sounds were recorded using either a portable hydrophone deployed from a boat or timer‐operated sonobuoys. Loudness of mating choruses of weakfish and silver perch was strongly correlated with the abundance of pelagic sciaenid‐type eggs, suggesting that these areas were used for spawning. Sonobuoy recordings showed that weakfish spawned only in the high‐salinity habitats near the inlets, spotted sea trout spawned predominantly in the low‐salinity areas near the river mouths, silver perch spawned in both high‐ and low‐salinity areas, and red drum spawned most commonly in low‐salinity areas, but only in September. The loudness of mating...
