  • Marine mammal interactions with trawl gear

    Underwater video technology was used to observe marine mammal interactions (seals, in particular Australian fur seals) within midwater trawl nets. A camera system was placed inside the trawl net in the vicinity of a Seal Excluder Device, designed to prevent megafauna from entering the codend of the net and provide an escape point. Digital video data was described according to a range of operational, catch and interaction fields, and made time-specific to each trawl shot. Data is linked to commercial catch and effort data providing operational, environmental and catch information.

    Analysis of giant crab brain lipofuscin data for age determination

    Lipofuscin density in Giant Crab (Pseudocarcinus gigas) brain tissue was estimated through fluorescent microscopy. The intent was to relate lipofuscin to crab age. Some known age specimens were included in the sample, these were reared from larvae.

  • Rock lobster (Jasus edwardsii) movement and behaviour data

    The movement and behaviour of the Southern Rock Lobster (Jasus edwardsii) was monitored using a radio acoustic telemetry systems at two sites in eastern Tasmania.

    Effects of water temperature and thermoclines on larval behaviour and development in the giant crab Pseudocarcinus gigas (Lamarck)

    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.

  • Abalone population length frequency data

    The dataset contains length frequency information for abalone species, collected in all Tasmanian state waters from 1988.

  • Southern Rock Lobster (Jasus edwardsii) catch sampling

    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.

  • Juvenile pale octopus (Octopus pallidus) growth

    The aim of this study was to assess how individual size-at-hatching and food consumption influences the growth of Octopus pallidus hatchlings reared under simulated seasonal temperature regimes in Tasmania.

  • Abalone abundance and algal cover information before and after translocation

    The dataset comprises abalone abundance and algal cover information on 'control' reefs and 'translocation reefs' in Tasmania.

  • Abalone commercial catch sampling

    The abalone commercial catch sampling project contains length-based samples from diver catches collected in Tasmania waters.

  • Abalone translocation

    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.
