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.

本次沿港区内拟建天然气管道线路开展了为期一周的试点调查，旨在搜寻分布于多处沉船与人工鱼礁上的黑体石首鱼（Protonibea diacanthus）鱼群。目前已完成相关磁带的读档分析，但港区水体时常浑浊，内港区域在小潮前的浑浊情况尤为突出。本次调查仅观测到1尾石首鱼。
