The purpose of this research is to investigate the distribution of seasonal fish schools in Chujado Marine Ranch Area. Acoustic surveys were conducted three times in May, August, and November 2019. The results of the survey were a low fish density in May and November while the highest density was re

marine ranching area, in order to understand the spatial distribution and strength of fisheries resources. Very high patches of fish were found in a wide area around the artificial reef. It is thought that an approaching fish school around the artificial reef can be measured accurately by using an e

fishing survey. The acoustic signals from individual fishes and small fish schools were mainly recorded around AO, but large and strong signals from large fish school were mainly detected in the top layer of and the water column near AC. The echogram suggest that the fish aggregation for the two typ

fish species of the demersal fishes in the marine ranching area (MRA) of Jeju. Four surveys were carried out in June, August, October and November using 38kHz quantitative echo sounder. Catch data using trammel net and trap were used to calculate biomass and to examine dominant fish species. Fish sc

fish population in all the water columns. Typically, the fish school showed different distribution density according to daytime, nighttime, and submarine topography. A systematic and ongoing investigation of the relationship between artificial reefs and fish population as well as seasonal changes in

fish in June and November was higher at night higher than during the day. The valley of the sea detected much fish. Thus, the distribution of the fish schools changed depending on time of day or night, month, and submarine topography. Therefore, it is thought that the systematic survey should be con

This study assessed dominant fish species, and the characteristics and spatio-temporal distribution of fish schools using acoustic and catch data in the marine ranching area (MRA) of Yeosu in July and August 2013. Acoustic data were collected using a 200-kHz dual beam transducer, and catch data were

fish biomass were 7.7 tons and 26.0 tons during daytime and nighttime, respectively. Winter biomass was 2.27 tons and 30.97 tons during daytime and nighttime, respectively. Different fish species form schools that exhibit different movements and behaviors, and thereby occupy varying water layers. Th
