Southern Rock Lobster (Jasus edwardsii) commercial fishery catch by block (in tonnes) and nominal Catch Per Unit Effort (CPUE, in kg/pot lift) per lobster fishing block per year for all depths. The data was retrieved from the Tasmanian Wild Fisheries Assessments site (https://tasfisheriesresearch.org/). Tasmanian wild fisheries stock assessments are conducted by the Fisheries and Aquaculture Centre of the Institute of Marine and Antarctic Studies (IMAS) on behalf of the Tasmanian Department of Natural Resources and Environment (NRE Tas). Under the Sustainable Marine Research Collaboration Agreement (SMRCA), IMAS conduct fishery assessments, provide expert management advice and undertake scientific research on Tasmanian fisheries issues for NRE Tas.

This project uses positional information from GPS loggers on abalone divers' boats and depth information from depth loggers attached to the divers for fine-scale spatial reporting of abalone fishing.

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.

The datasets contain summaries of Tasmania Natural Resources and Environment logbook data on catch and effort distribution for Tasmanian commercial fisheries in state marine and estuarine waters. The logbook data has been recorded and submitted to NRE by commercial fishers. The data are aggregated to produce summaries of total catch and effort by fishery at a 5 degree resolution where 5 boats or more operate. For areas where less than 5 boats operate the data is shown as confidential. The data was mapped using 5 year - financial year periods; 2003/04 to 2007/08, 2008/09 to 2012/13, 2018/19 to 2022/23, and 1 year; 2022/23.

The effect of barrens formed by the long spined sea urchin, Centrostephanus rodgersii, on the standing stocks of southern rock lobsters (Jasus edwardsii) and black lip abalone (Haliotis rubra) was estimated by divers using underwater visual census methods to compare lobster and abalone abundance in barrens with that in adjacent kelp habitat. Abalone (H. rubra) and rock-lobster (J. edwardsii) populations were compared on C. rodgersii barrens and in adjacent algal-dominated habitat at the same depth and on the same substratum type at three sites in eastern Tasmania (Elephant Rock:Binalong Bay, St Helens Is, and Mistaken Cape:Maria Island). At Elephant Rock and St Helens Island , the barrens are extensive and well established Type 1 barrens, while at Mistaken Cape the barrens in 8-14 m are incipient Type 4 barrens, comprising small barren patches in the algal bed (see FRDC report for classification of barren types). Note that while there are extensive barrens in deeper water (>18 m) at Mistaken Cape, at these depths working time is limited and it was difficult to locate intact macroalgal beds on equivalent substrata.

This report provides an assessment of the social and economic status and performance of Tasmanian fisheries and aquaculture, 2017/18 to 2020/21. Tasmania’s fisheries and aquaculture sectors (i.e., commercial, recreational and Tasmanian Aboriginal businesses and users) are important parts of the Tasmanian economy and broader community and generate a diverse range of social and economic benefits. Achieving economic and social benefits from marine resources is an objective of fisheries and marine farming (aquaculture) management in Tasmania, as outlined in the Living Marine Resources Management Act 1995 (hereafter referred to as LMRMA) and the Marine Farming Planning Act 1995 (hereafter referred to as the MFPA). The indicators used in this assessment reflect this legislative objective as well as best-practice (for example, see NOAA Fisheries Socioeconomics, PIRSA Social and Economic Assessments). They were chosen to be relevant to managing sector-wide and community outcomes from these fisheries and aquaculture activities. This report does not attempt to benchmark performance. It is intended to inform industry and sector representative organisations, government agencies with policy and regulatory responsibilities, other marine research groups, and interested members of the Tasmanian community, of social and economic outcomes and change in those outcomes across time. This is the first assessment report of this type. It follows from an initial pilot assessment of Tasmanian fisheries (Ogier et al. 2018) and is intended to be one of a series. The period of time covered by this assessment (2017/18 - 2020/21) encompasses both the period prior to and across the COVID-19 pandemic. The impacts of the pandemic on economic and social indicators for these sectors is therefore captured. This assessment encompasses commercial, recreational, and Tasmanian Aboriginal community sectors using managed marine resources. The findings are based on a range of assessment and research activities undertaken by the Institute for Marine and Antarctic Studies (IMAS) of the University of Tasmania. Specific fisheries and aquaculture sectors assessed are: Tasmanian Abalone Fishery, Tasmanian Giant Crab Fishery, Tasmanian Rock Lobster Fishery, Tasmanian Scalefish Fishery, Tasmanian Scallop Fishery, Tasmanian Abalone Aquaculture, Tasmanian Pacific Oyster Aquaculture and Tasmanian Salmonid Aquaculture.

Southern Rock Lobster catch and effort information monitoring fluctuations in South Australia since 1969. The fishery is divided into 2 zones northern and southern. The rock lobster fishery is a single species (Janus edwardsii) fishery. It operates seasonally and is a quota managed fishery.
