1981Present-day hunting and distribution of dugongs in the Wellesley Islands (Queensland): implications for conservation.
Biol. Conserv. 19(4): 255-267. 2 tabs. 4 figs. Apr. 1981.
—Describes present hunting techniques using harpoons and outboard motors, and the results of aerial surveys of the Wellesley Islands area. Peak hunting activity coincides with seasonal movements of dugongs; 374 animals were counted, of which about 40 are taken each year. Hunting is now easier and less dangerous, but some sociological factors discourage it, and some hunters try to avoid taking pregnant females.
