The results of the observation was summarized as follow: (1) Deep scattering layer (DSL) was detected by 200 KHz Fish-finder and it was consist of 3 layers. (2) These layers changed their depth diurnally, and vertical movement of the 3 layers of DSL varied in response to the submarine illumination. (3) The velocity of descending or ascending movement of DSL at the sunrise or sunset was recorded as fast as 1~2 m/min.}, pages = {1--8}, title = {200KHz魚群探知機による鹿児島湾におけるD.S.L.の記録について}, volume = {23}, year = {} }
