Surveys to locate black jewfish (Protonibea diacanthus) aggregations in Darwin Harbour, Northern Territory, using baited remote underwater video stations (BRUVS (TM))

A one week pilot survey was conducted along the proposed gas pipeline route within Darwin 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.

This research was undertaken to characterise the fish populations

Statement
Statement: Tape reading protocols have been developed in a customised interface using Microsoft Access. The unique combination of a site and a Camera Number links all records in a series of tables in the relational database, allowing access to times that events occurred, together with reference images and reference video. The BRUVS (TM) were deployed about 350-400m apart with the prevailing wind to bracket the coordinate of each sampling site. In some instances, a stereo-video BRUVS (TM) was deployed first, followed by three or four BRUVS (TM) with single cameras. Each BRUVS (TM) consisted of a galvanized trestle-shaped frame enclosing a simple camera housing made from PVC pipe with acrylic front and rear ports. Mini-DV HandiCams with wide-angle lens adapters (0.6X) were used in the housings. Exposure was set to 'Auto', focus was set to Infinity/manual' and 'Standard Play' mode was selected to provide at least 45-60 minutes of filming at the seabed. Detachable bait arms (20 mm plastic conduit) had a 350 mm plastic mesh canister containing one kilogram of crushed oily sardines (Sardinops or Sardinella spp) as bait. BRUVS (TM) were deployed with 8 mm polypropylene ropes and polystyrene surface floats bearing a marker flag, and were retrieved with a hydraulic pot-hauler wheel. A scope length of 2 times water depth was used on the ropes.
