  • Projects including exploratory trawl surveys of the shelf and slope waters off southern Australia, targeted studies of specific fisheries, e.g. trawl fisheries for blue grenadier and orange roughy, purse seine fishery for jack mackerel, gillnet fishery for blue warehou, the coastal reef fishery for live fish fishery, inshore shark fishery, along with commercial catch sampling (on board and market sampling) have yielded an extensive dataset that includes biological, distribution and abundance information for a diverse range of finfish species from South East Australia. These data have been compiled into a single database and cover collections made between the late 1970s and mid 1990s. Note, selected data for key species (e.g. banded morwong, bastard and striped trumpeter) have been extracted and uploaded into Access databases (refer to scalefish research database, post mid-1990s).

  • The data is quantitative abundance of fish and megafaunal invertebrates and algal % cover derived from transect based counts at a wide range of locations across Temperate Australia. The methods are described in detail in Edgar and Barrett (1997). Primarily the data are derived from transects at 5 m depth and/or 10 m depth at each site surveyed. Methods were initially developed for research on temporal changes following protection in Tasmanian long-term MPAs (Maria Is, Tinderbox, Ninepin Point, Governor Island), and the data represented by this record has been collected at Governor Island. In many cases the dataset involves temporal replication (year scale), particularly for the core Tasmanian MPAs represented by this record.

  • Utilising both fishery independent and industry dependent surveys, spatial and temporal data was collected on scallop, and other bethnic community, abundance. The dataset also includes dredge video surveys and, in some instances, bycatch abundance.

Methods were initially developed for research on temporal changes following protection in Tasmanian MPAs (Maria Is, Tinderbox, Ninepin Point, Governor Island). The data represented by this record was collected in MPA studies and surveys interstate, and was collected from Jurien Bay (WA). In many cases the dataset involved temporal replication (year scale).

  • The spatial extent of C. rodgersii "barrens" was estimated by surveying rocky reef habitat with a towed underwater video system. Sampling took place at 13 regions along the east coast of Tasmania, each comprising 3 subsites, this dataset refers to the Nubeena region, and its 3 subsites: Cape Raoul, Salters Point and Wedge.

    The spatial extent of C. rodgersii "barrens" was estimated by surveying rocky reef habitat with a towed underwater video system. Sampling took place at 13 regions along the east coast of Tasmania, each comprising 3 subsites. Substrate and habitat type were recorded using video analysis, with 4 categories of urchin barren habitat recognised (see below for definitions).

  • Utilising both fishery independent and industry dependent surveys, spatial and temporal data was collected on scallop, and other bethnic community, abundance.

  • Stable isotope data, fatty acid and diet data was collected from a number of predator species in the southern ocean. Data was collected from blood, blubber, feathers and whisker samples

  • Categories  

    Raw time series of depth, water temperature, light and swim speed. Stomach temperature and heart rate are available in some instances, but the data is sparse. Data was collected using time/depth recorders and satellite telemetry. Ancillary location was recorded from a separate logger.
