Abstract

This project took advantage of an unprecedented deployment of acoustic receiver infrastructure around the Western Australian coast to monitor a large number of sharks implanted with acoustic tags. This research was undertaken to better understand the temporal and spatial dynamics of commercially-important sharks in Western Australia, which has enabled a re-evaluation of the risks of cryptic sources of catch and bycatch to dusky and sandbar shark stocks and development of population simulation models with which to test the implications of spatially-different histories of fishery management, as well as future spatial-management arrangements for whiskery and gummy sharks stocks.
