Fishing Effort Maps Based on Commercial Fishing Logbook Data - Tasmania 2011-2015

Full description

This data contains summaries of TAS Department of Primary Industries, Parks, Water and Environment (DPIWE) non-confidential logbook data on effort distribution for TAS commercial scalefish fisheries in state marine and estuarine waters. The logbook data has been recorded and submitted to TAS DPIWE by commercial fishers.

The data are aggregated to produce summaries of total effort by fishing activity or method (summarised across fishery), over 5 year periods and at the scale of fishery reporting blocks where 5 boats or more operate. All effort information has been removed for areas where less than 5 boats operate and these areas are mapped to a 1 degree resolution.

The 5 year period (2011-2015) corresponds to State of Environment (SoE) Reporting, required under the EPBC Act 1999. Each map layer is labelled by the years aggregated (“2015” for 2011-2015) and the gear type (“GN_MN” = gillnet and mesh net). The gear codes and aggregated fisheries and the shape file field descriptions are listed below.

The data were supplied for the purpose of research being undertaken by CSIRO under the NESP Marine Biodiversity Hub to produce an interactive map of pressures on the marine environment (at a broad spatial scale) that will enable a systematic understanding of the different pressures acting in different areas. Please contact the TAS Department of Primary Industries, Parks, Water and Environment for permissions to use the data for another purpose.

1. Care needs to be taken when interpreting the fishing effort maps because in areas where there are less than 5 boats operating only the fishing footprint is displayed, consistent with the TAS DPIWE Information Disclosure Policy. The fishing footprint indicates that fishing occurred but does not provide information about the intensity of effort.
