In this study, density change of fish and zooplankton living around artificial reef is surveyed using hydro-acoustic technique.
The survey was carried out around artificial reef at marine ranching area in Ando, Yoesu from 5 P.M, October 29<SUP>th</SUP>, 2013 to 9 A.M, the next day. Acoustic survey was conducted using a 200 ㎑ dual beam transducer(DT5000, Biosonics). In addition, marine environment of water temperature, salinity and air illumination were observed every two hour by CTD (Mini CTD, Valeport) and air illuminometer(TES-1335).
The surface water temperature was 19.7~20.2℃ while the bottom water temperature was 19.8~20.6℃ showing no significant differences according to different time periods. The surface salinity were 32.6~32.8 psu while the bottom salinity were 32.6~33.2 psu showing no significance differences according to different time periods. The air illumination decreased rapidly after the sunset and increased rapidly after the sunrise. The fish density recorded the highest at the sunset while the zooplankton density tended to increase after the sunset and decrease after the sunrise.
