  • Mesozooplankton community composition and structure were examined throughout the D’Entrecasteaux Channel, Huon Estuary and North West Bay, Tasmania, from November 2004 to October 2005, the data represented by this record was collected on the 11/02/2005. The composition of the mesozooplankton community was typical of inshore, temperate marine habitats, with seasonally higher abundance in summer and autumn and lower numbers in winter and spring. Copepods were the largest contributors to total abundance across all seasons and stations, while cladocerans and appendicularians were proportionally abundant in spring and summer. The faecal pellets of these three main groups, along with those of krill and amphipods, also contributed significantly to material recovered from sediment traps. Meroplanktonic larvae of benthic animals showed short-term peaks in abundance and were often absent from the water column for long periods. Spatially, North West Bay and the Channel had a higher representation of typically marine species, including Calanus australis and Labidocera cervi, while truly estuarine species, such as the copepod Gladioferens pectinatus, were more important in the Huon Estuary.

    The Fisheries Research and Development Corporation Project (FRDC) No. 2001/060 characterised and identified the distribution of the different benthic habitats of the Recherche Archipelago and identified the distribution of assemblages of fish, mobile invertebrates, filter feeding communities and seagrasses and the patterns and processes which structure them. Benthic habitat were determined from the interpretation of Landsat imagery, sidescan sonar imagery and video validation data collected within the Recherche region from May 2002 to November 2003.

  • Raw acoustic data files for Tasmanian coastal waters from the LWM (Low water mark) to 40 metres in depth or 1.5 kms from shore.

  • Describes the database used for storing Southern Rock Lobster (Jasus edwardsii) biological data collected by observers on commercial boats and dedicated research trips incorporating information on sex, length, weight, damage, reproduction, bycatch, protected species interaction, location, depth, tagging and equipment type.

    Conducted a series of laboratory experiments to investigate the effect of temperature on swimming behaviour and development. Swimming behavioural responses were monitored for the first two zoeal stages, while larvae in development trials were reared through all five zoeal stages to the megalopa stage.

  • Data collected to measure foraging and reproductive success. Stored as time series data including mass, condition (fat stores), length, girth, offspring survival and growth. Data collected and methodology used varies depending on species.

  • This projects' data on abalone translocations is stored in two databases containing data collected for abalone aggregation and larval surveys in Tasmania. Genetic information has also been generated using microsatellites.

  • Between January 2000 and January 2007, sharks were tagged during routine fishery dependent and independent rock lobster catch sampling trips around southwestern and eastern Tasmania and in the Crayfish Point Reserve. For each shark, sex, total length and clasper length (males) were recorded.

  • Sandy beaches on Tasmania's east coast, from Catamaran to Cape Portland, were sampled between September 1994 and June 1995. At each of 120 sites the strandline fauna was sampled using pitfall traps set overnight during the low tide period. A number of physical and biotic characteristics of each beach were also measured.
