초록
Some of the mariculture grounds near Ongjin-gun, Korea, were designated as mariculture management areas in 2007. Areas are so designated when the environmental quality of the mariculture ground deteriorates or there is an outbreak of hypoxia or harmful red tide that kills mariculture organisms. We surveyed the water and sediment quality and examined the mortality of mariculture organisms in the Ongjin-gun mariculture area. In a survey conducted in 2016, the water quality was better than the environmental quality standards for mariculture grounds, excepts for dissolved inorganic nitrogen, and the sediment quality was good. However, there was still mortality of mariculture organisms in some of the designated management areas. The areas that met the environmental quality standards should be delisted and the areas in which we observed mortality should be classified as management areas. This will enable the sustainable development of aquaculture and preserve healthy mariculture grounds.
Abstract
Some of the mariculture grounds near Ongjin-gun, Korea, were designated as mariculture management areas in 2007. Areas are so designated when the environmental quality of the mariculture ground deteriorates or there is an outbreak of hypoxia or harmful red tide that kills mariculture organisms. We surveyed the water and sediment quality and examined the mortality of mariculture organisms in the Ongjin-gun mariculture area. In a survey conducted in 2016, the water quality was better than the environmental quality standards for mariculture grounds, excepts for dissolved inorganic nitrogen, and the sediment quality was good. However, there was still mortality of mariculture organisms in some of the designated management areas. The areas that met the environmental quality standards should be delisted and the areas in which we observed mortality should be classified as management areas. This will enable the sustainable development of aquaculture and preserve healthy mariculture grounds.
