The purpose of this project was to study the use of mid-water and surface structures (Fish Aggregating Devices - F.A.D.'s) in attracting commercial species of pelagic fish in economic quantities.
Fishing activity was captured across 53,852 one Hectare hex grid cells across Tasmania. A total of 113,164 diving hours were recorded across 125,536 individual fishing events (Table 1). Between 2012 and 2016, the Tasmanian Geo-Fishery Dependent Data (GFDD) program captured between 85 % and 90 % of...
Experimental trawling in Gulf St Vincent indicated that epifaunal assemblages experienced substantial trawling mortality, which varied depending on sediment characteristics. Locations with strong currents and coarse sediments experienced minimal effects, whereas those with weak currents and...
The NRFS involved three stages of data collection. An overview of the three stages of data collection and the purpose of each, and a guide summarising which chapters draw on data from each stage of data collection, are provided in the next section. Sections 3.4, 3.5 and 3.6 provide a detailed...
Results from the current ‘proof of concept’ study indicate that near infrared (NIR) spectra collected from fish otoliths have potential to estimate the age of Barramundi (Lates calcarifer) and Snapper (Pagrus auratus), with performance varying between species and locality of capture. A...
