Darwin Harbour fish and shark surveys by baited video (BRUVS).

A one week pilot survey was done along the proposed gas pipeline route within the harbour, and in search of black jewfish aggregations (Protonibea diacanthus) on a number of shipwrecks and artificial reefs. The tapes have been read, but the water was often turbid - especially before the neap tide in the inner harbour. Only a single jewfish was sighted.
