This study analyzed cases of mass mortality in fish farms located in the south coasts of Korea from 1998 to 2016 to help minimize damage to fisheries. Reports and documents on damage investigation from the National Institute of Fisheries Science (NIFS) were used for the study. During this period, 148 cumulative analyses were conducted for 1,445 cases totally, including 1,367 cases of marine cage aquaculture farms (94.6%), 77 cases of onshore aquaculture farms (5.3%), and 1 case of enclosure aquaculture farms. The number of annual damage investigations and damaged fish farms tended to increase rapidly after 2011. The causes of mass mortality of cultured fishes included harmful algal blooms (HABs, 37.4%), high water temperature (31.0%), and low water temperature (26.5%), altogether accounting for approximately 95% of the total incidences of fishery damage. Apart from the three major causes, other causes included biological diseases (1.6%), blue tide (0.6%), nutrition and nutritional diseases (0.3%), and unidentified causes (1.6%). However, most of the mass mortality cases could not be clearly attributed to a single cause; however, other causative factors were also considered to be involved before or during mass mortality. Additionally, the majority of the mass-mortality cases occurred between January and March and between July and October, representing periods of low and high water temperature, respectively. Therefore, fishery-damage prevention programs suitable for such characteristics of Korea should be developed. These programs should include transformation of social awareness, improvement of the system, preparation against global warming, management of aquaculture environments, improvement of fishery systems, management of fish farms, and control of nutrition status and diseases.
