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.

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.

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.

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.

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.

Sandy beaches on the north and west coasts of Tasmania, and on Flinders and King Islands were sample between October 1996 and August 1997. At each of 102 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.

This study aims to undertake a comprehensive survey of the benthic fauna of Port Davey – Bathurst Harbour and adjoining Payne Bay, James Kelly Basin and Hannant Inlet. This will provide important information on the composition and structure of benthic faunal communities and the distribution of any introduced species amongst the benthos. In February/ April 2007 invertebrate faunal communities were sampled at 70 locations throughout the system – with the greatest intensity of sites located within Port Davey, Bathurst Channel and Bathurst Harbour.

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

Rock Platforms on Tasmania's east coast, Flinders Island, and the north coast as far west as Port Sorell, were surveyed between December 1995 and September 1996. At each of 51 sites two transects were sampled using quadrats. All animals and plants were counted, or in the case of sessile species, their cover was estimated.
