A marine ranch is a sea area that artificially creates habitats where artificial structures or natural stones can be installed to inhabit and grow. The purpose of this study is to investigate the vertical and horizontal distribution of fish schools by distance around artificial reefs in central Taean using acoustic survey. The survey was conducted on April 27(1st), July 28(2nd), September 30(3rd), and November 17(4th). According to the survey, more fish schools appear in April and July than in September and November, and more fish schools appear at night than during the day. When examining the density of fish schools by distance of 2km, 3km, and 4km from artificial reefs, the frequency of appearance decreased as the distance from artificial reefs increased. As a result, changes in the distribution of fishing schools were found depending on the day and night and the presence or absence of artificial reefs. Data should be collected and stored using sound research equipment WBT, GPS, Transducer, and Notebook, and it is judged that follow-up management and continuous observation of fisheries resource creation projects are necessary.
