Courageous Cruise 035 Biological Data overview, 1978

This record describes the datasets obtained on Courageous Cruise 035. The data were obtained from the Australian NW Shelf (Port Hedland and York Sound areas) in May and June 1978. Data were obtained from acoustic and trawl surveys of pelagic and demersal fish. Predominant species included goatfish (Mullidae), threadfin bream (Nemipteridae), lizard fish (Synodontidae), scad and trevally (Carangidae), pufferfish (Tetradontidae), bigeye (Priacanthidae), emperor (Lethrinidae) and sea perch (Lutjanidae). Five species of Scombrid included leaping bonito (Cybiosarda elegans), frigate mackerel (Auxis thazard), eastern little tuna (Euthynnus affinis), big-eye tuna (Thunnus obesus) and Indian mackerel (Rastrelliger kanagurta). Several individual tuna were trolled, including skipjack tuna (Katsuwonus pelamis) and northern bluefin tuna (Thunnus thynnus). Length, numbers, weight and target signal strength were determined. Two XBT, nutrient and plankton sampling transects were also completed.
