Abstract
It has been considered that fishing areas for shrimp beam trawl have been in ruin because Korean localgovernments have permitted trawling into the areas limited by the fisheries local regulations from 1994.Physical and biological effects of the trawling were investigated in the study. Physical effects wereinvestigated by optical methods such as trawling tracking by side scan sonar and comparing the gear bothbefore and after trawling. Biological aspects were investigated by grab sampling of benthic animals,concentration of trace metals in sediment and a flux evaluation of NH
