-
The abalone commercial catch sampling project contains length-based samples from diver catches collected in Tasmania waters.
-
The dataset comprises abalone abundance and algal cover information on 'control' reefs and 'translocation reefs' in Tasmania.
-
In 2006, transect surveys were conducted at sites in eastern inshore Tasmanian waters at depths and habitats typical of those where abalone are commercially fished. Surveys focused on four areas of the Tasmanian coastline including St Helens, Bicheno and Dunalley on the east coast and the Actaeons region on the south-east coast; with at least 10 reefs sampled in each region.
-
Recreational abalone fishing data for the periods between 2002/03 to 2024/25 for eight assessment areas in Tasmania. The data includes estimated catch (in kilograms and numbers of abalone), estimated effort (in fishing days) and estimated catch rate (in number of abalone/fishing days). Both species, blacklip abalone (Haliotis rubra) and greenlip abalone (Haliotis laevigata) are targeted by the recreational fishers. The data was compiled from the Tasmanian Recreational Rock Lobster and Abalone Fisheries survey reports produced by IMAS. The assessments are conducted using a survey involving a random sample of licence-holders who are contacted by telephone prior to the start of the fishing season and invited to participate in a phone-diary survey to monitor their abalone fishing activity between November and April.
-
The survey comprises two streams of data, including (1) the availability of different attachment sites and (2) the algal composition of abalone attachment sites ('homesites'). The survey was conducted at three sites at each of three regions on the east coast of Tasmania.
