Assessing changes in numbers and distribution of large whale entanglements in Newfoundland and Labrador, Canada
Entanglements of large whales in commercial fisheries in Newfoundland and Labrador, Canada, have been consistently recorded since 1979, as part of a program aimed at releasing captured animals and reducing costs to fishermen. This data set represented an opportunity to identify fisheries posing part...
