Abstract An unusual effect of attracting fish shoals by intensive internal waves was observed in the shelf zone of the Black Sea. A shoal of fish that followed a train of intense internal waves moving to the shore was detected during research using an acoustic Doppler current profiler (ADCP) in the shelf zone near the city of Gelendzhik. The wave train consisted of internal waves unusually large for the Black Sea, up to 16 m high. Orbital currents initiated by these waves intensively stirred up the sediments, which contained some nutriments attractive to the fish. The most pronounced turbulence effect was produced by two head waves of the train, which had maximum amplitudes, near which the shoals of fish were discovered. The shoals followed the internal waves for 2.5 hours, until the waves faded out upon approaching the shore.

登记被孤立密集内波吸引的鱼群

摘要 在黑海陆架带观察到强烈的内波吸引鱼群的异常效应。研究期间，在格连吉克市附近的陆架区使用声学多普勒电流剖面仪 (ADCP) 检测到一群鱼跟随一列强烈的内波移动到岸边。波列由黑海异常大的内波组成，高达 16 m。这些波浪引发的轨道流强烈地搅动了沉积物，其中含有一些对鱼类有吸引力的营养物质。最显着的湍流效应是由火车的两个头波产生的，它具有最大的振幅，在它们附近发现了鱼群。浅滩跟随内波持续了 2.5 小时，直到靠近岸边时海浪逐渐消失。
