Seasonal distribution and abundance of dugongs in the western Gulf of Carpentaria.
Austral. Wildl. Res. 16(2): 141-149. 5 tabs. 4 figs.
–Aerial surveys in 1984-85 showed no major seasonal changes in distribution and relative abundance. Mimimum population sizes of 16,816ñ2946 (dry season) and 16,846ñ3257 (wet season) were calculated. Abundance was correlated with area of available seagrass beds. Catch rate by Aboriginal hunters declined from about 60 to 10 per year between the 1960s and 1985, possibly due to excessive hunting, but the present harvest rate appears to be sustainable.
