Current stock situation and measures for the management and conservation of minke whales (Balaenoptera acutorostrata) in Korean waters

摘要: Abstract Although minke whales in Korean waters have been protected for more than 28 years after a commercial whaling moratorium 1986, relatively little effort has focused on assessing their current status of this population area protection and the efficacy protection. Thus, stock situation measures management conservation was investigated. Korea undertaken significant efforts to archive biological material bycaught whales, results remain incomplete. Furthermore, although number studies reported extent there reduce occurrence compared with report it. Finally, exists data investigating effect bycatch survival waters. To improve weaknesses efficiently conserve manage population, following are urgently needed: 1) Conduct research including satellite tagging; 2) Establish DNA registers all whale bycatch, market surveys intensive control illegal catch; 3) Assess usefulness several mitigation (pingers, fishing gear modifications time-area closures), apply these measures; 4) waters; 5) Reduce incentive use it as funds incentives releasing entrapped or entangled gears; 6) Compare other suggestions modify situation. Among situation, application catch expected by reducing catch. Particularly, among measures, modification pinger considered efficient area.
