“…In South Korea, by-caught minke whales can legally be sold and a reporting system has been in place there since 1994. Although reporting of animals is not always accurate, these data show that from 1996 to 2014, minke whales by-caught in Korean waters alone exceeded the estimated level of potential biological removal (PBR) for this population (Song, 2016). Due to their small size, minke whales are more likely to die as a result of entanglement than other species, as they are less likely to be able to reach the surface when weighted down by fishing gear and more often sink after death, which may also lead to under-reporting of entanglement cases for this species (Knowlton et al, 2016).…”

“…While the sub-population called "J stock" inhabits the Yellow Sea, East China Sea and the Sea of Japan, "O stock" inhabits more offshore waters of the Northwest Pacific and the Okhotsk Sea (Kato, 1992). There has been serious concern and debate within the IWC about the status of J stock, which in addition to being targeted by whaling operations, is also frequently caught incidentally in fishing gear (Song, 2016;Cooke et al, 2018a). The current 3 https://iwc.int/home (accessed March 29, 2019).…”

Minke whales comprise some of the most widely distributed species of baleen whales, some populations of which are still regularly targeted by commercial whaling. Here, we review the conservation status of common (Balaenoptera acutorostrata) and Antarctic (Balaenoptera bonaerensis) minke whale populations, against the backdrop of ongoing whaling operations and other anthropogenic threats, including climate change, entanglement in fishing gear, ship strikes, and noise pollution. Although some coastal minke whale populations have been studied in detail, others, which inhabit remote and ecologically sensitive locations, such as the Antarctic ice shelf, are among the least understood populations of marine mammals. The unresolved taxonomy of dwarf minke whales further highlights some of the existing knowledge gaps concerning these species. Due to their relatively small size and elusive behaviors, large uncertainties exist for almost all minke whale populations with respect to behavior, migratory routes and winter distributions, hindering effective conservation and management. However, recent advances in research technology, such as passive acoustic monitoring (PAM), unmanned aerial systems (UAS), multisensor recording tags, and machine learning assisted photo-identification, are increasingly being applied to study minke whales and their habitat, and are starting to open new windows into their life history and ecology. In future research, these non-and less-invasive methods should be integrated in larger-scale comparative studies aiming to better understand minke whale behavior, ecological interactions and their varying habitats to drive and support effective species conservation.
