Globally, the survival of many marine mammals is threatened by entanglement in fishing gear and there is also a high
bycatch in Korea. This study analyzed the bycatch data of most cetacean species for Korean waters from 2011 to
2017, including the narrow-ridged finless porpoise Neophocaena asiaeorientalis, common dolphin Delphinus delphis,
common minke whale Balaenoptera acutorostrata, and Pacific white-sided dolphin Lagenorhynchus obliquidens. A
total of 12,262 cetaceans were captured as bycatch. In the Yellow and South Seas, the main species affected was the
narrow-ridged finless porpoise, with 82.9% caught in stow nets and 11.5% captured in trawls. In the East Sea, the
common minke whale, common dolphin, and Pacific white-sided dolphin were reported. The main common minke
whale bycatch (43.5%) was in set nets, while common dolphins (49.0%) and Pacific white-sided dolphins (91.4%)
were mainly caught in gill nets. The narrow-ridged finless porpoise, common dolphin, and common minke whale
were most commonly reported in March, April, and May, while the Pacific white-sided dolphin was most frequently
captured as bycatch in January and December. Each of these factors (season and gear responsible for bycatch) depended
on the characteristics of the cetacean species. To conserve cetaceans, it is necessary to reduce the bycatch
