Catch statistics for belugas in West Greenland 1862 to 1999
Information and statistics including trade statistics on catches of white whales or belugas (Delphinapterus leucas) in West Greenland since 1862 are presented. The period before 1952 was dominated by large catches south of 66o N that peaked with 1,380 reported kills in 1922. Catch levels in the past...
