Summaries of AFMA log book data on effort distribution for Commonwealth fisheries in the Australian Exclusive Economic Zone

Brief description

This data set contains summaries of AFMA log book data on effort distribution for Commonwealth fisheries in the Australian Exclusive Economic Zone (excluding Cocos and Christmas Islands, Norfolk Island and the Sub-Antarctic Fisheries). The logbook data has been recorded and submitted to AFMA by commercial fishers. The data has been aggregated to produce summaries of total effort by gear type (summarised across fishery), over 5 year periods and at a 0.1 degree resolution 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 years periods (1996-2000, 2001-2005 and 2006-2010) correspond to State of Environment (SoE) Reporting, required under the EPBC Act 1999. The most recent reporting period (2011-14) is a four year period. Each is labelled by the years aggregated (ie 2001-2005) and the gear type (ie LLP = long line pelagic). The gear codes and aggregated fisheries and the shape file field descriptions are listed below.
Notes:
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 AFMA Information Disclosure Policy. The fishing footprint indicates that fishing occurred but does not provide information about the intensity of effort (number of operations etc).
2. Legal fishing by foreign flagged vessels occurred in the 1980s and early 1990s in the Australian Fishing Zone. These are shown as areas of higher effort in (i) trawl maps prior to 1990 north of Arnhem Land and (ii) pelagic longline maps up until 1997 south of Tasmania.
3. Minor line was historically recorded as a method in some of AFMA’s daily fishing logbooks, but is not in AFMAs current fishery logbooks. Minor line means trolling, or fishing using a rod or reel, handline or pole.
4. Trawl effort maps are missing Torres Strait Prawn Fishery data prior to 2004.
5. Gillnet effort maps prior to 1996 are not included due to data incompleteness.
6. Jigging data is currently incomplete and is not included.
7. Three records of Danish Seine were misreported (between 1996 and 2010) in the area of the Great Barrier Reef and have been removed.
8. Minor line was historically recorded as a method in some of AFMA’s daily fishing logbooks, but is not in AFMAs current fishery logbooks. Minor line means trolling, or fishing using a rod or reel, handline or pole.
