–Spanish summ. On the basis of aerial surveys in 1987 and 1991 and catch statistics, concludes that the annual catch approximates 5% of the estimated dugong population and is likely to be unsustainable. An increase in the Torres Strait population between the aerial surveys is thought to have been due to redistribution of dugongs within the survey region or to immigration, probably from Irian Jaya. For effective dugong management, the Torres Strait Islanders must be involved in management decisions and efforts.
