Marine mammals interactions with tuna fishing activities in Indonesian seas
Abstract For decades, marine scientists have known that fisheries throughout the world result in mortality for cetaceans (whales, dolphins, and porpoises). Incidental catch (also known as by-catch) in fisheries is considered the biggest threat to the survival of cetaceans globally. Migratory species...
