Shark Attacks in New Guinea Waters.

Abstract

Information concerning the prevalence of sharks in New Guinea waters was obtained in inshore netting fests close to Port Moresby in Bootless Inlet in the dry season (May to November) of 1954. These experiments showed that shoals of small sharks up to 3 ft. 6 in. total length entered these waters which have a salinity up to 4.1 parts salt per 1,000. The estuaries become stable environments in the south-east season without any influence from fresh water, and ocean fish species enter the inshore waters sometimes in large numbers. The sharks come to prey on these fish.
