The Guide to the Marine Zooplankton of south eastern Australia, is an interactive tool providing a comprehensive, fully illustrated means of identification for the major zooplankton located in south eastern Australia. This new identification guide to local marine zooplankton is available online at: http://www.imas.utas.edu.au/zooplankton This is the result of collaboration between the Marine Research Laboratories and School of Zoology, University of Tasmania, and the Australian Antarctic Division.

Underwater visual census surveys were conducted at 15 sites in eastern Tasmania to quantify the abundance of the sea urchin Heliocidaris erythrogramma and several putative predators.

Growth models were constructed for two sea urchin populations over a two-year period using a tag-recapture study in the Mercury Passage, Tasmania. Sea urchins were tagged using tetracycline and calcein and growth models constructed using measurements taken from sea urchin jaws.

The aim of this study is to use artificial boulders in the form of sandstone blocks to investigate the benthic cryptofaunal communities of subtidal rocky reefs; specifically to quantify temporal and spatial patterns, the influence of the sub-block reef profile, and protection from fishing on these animals at locations inside and external to the Maria Island marine reserve in eastern Tasmania.

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.

Abalone growth data include estimates from growth increment data from tagging studies, and from shell ageing studies. Data has been collected from all Tasmanian state waters since 1986.

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

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.

Sea urchin tagged using tetracycline display visible marks in jaw elements and test plates that can be used to determine growth and subsequently an individuals age. Natural growth lines in the same structures can be used to determine age if natural lines are deposited at a consistent rates independent of age. Sea urchins were tagged using tetracycline and age determined from both fitted growth models and the number of bands deposited. Rates of natural line deposition were also quantified.

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