The WCPFC have compiled a public domain version of aggregated catch and effort data using operational, aggregate and annual catch estimates data provided by Commission Members (CCMs) and Cooperating Non-members (CNMs). The data provided herein have been prepared for dissemination in accordance with the current Rules and Procedures for the Protection, Ac- cess to, and Dissemination of Data Compiled by the Commission or (RAP). Paragraph 9 of the Rules and Procedures indicates that ”Catch and Effort data in the public domain shall be made up of observations from a minimum of three vessels”. However, the majority of aggregate data provided to WPCFC do not indicate how many vessels were active in each cell of data which would allow data to be directly filtered according to this rule. Instead, the individual cells where ”effort” is less than or equal to the maximum value estimated to represent the activities of two vessels have been removed from the public domain data. Statistics showing how much data have been removed according to this RAP requirement are provided in the documentation for the longline and purse seine public domain data. All public domain data have been aggregated by year/month and 5x5 grid. Annex 2 of the RAP indicates that public domain aggregated catch/effort data can be made available at a higher resolution (e.g. data with a breakdown by vessel nation, and aggregated by 1x1 grids for surface fisheries); however, if the public domain data were provided at these higher levels of resolution implementation of the RAP ”three-vessel rule” with the current aggregate data set would result in too many cells being removed. Records are for Albacore, Yellowfin, Bigeye, Striped Marlin, Black Marlin, Blue Marlin, Swordfish and SkipJack Tuna. The data is summarised for Tuna, Marlin, Swordfish and other species and mapped by the catch per hook for each species group, averaged annually.
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. 9. Disclaimer: The data provided by AFMA may contain errors or be incomplete.

The Flinders Commonwealth Marine Reserve (CMR) survey was a pilot study undertaken in August 2012 as part of the National Marine Biodiversity Hub's National monitoring evaluation and reporting theme. The aim of this theme is to develop a blueprint for the sustained monitoring of the South-east CMR Network. The particular aims of the survey were twofold; 1) to contribute to an inventory of demersal and epibenthic conservation values in the reserve and 2) to test methodologies and deployment strategies in order to inform future survey design efforts. Several gear types were deployed; including multibeam sonar, shallow-water (less than 150m) Baited Remote Underwater Video Systems (BRUVS), deep- water BRUVS (to 600 m), towed video and digital stereo stills. This resource contains the deep-water BRUVS footage captured on the slope (~500m depth) of two sites: the Flinders CMR and the adjacent Cape Barren fisheries closure. At each site 3 stereo deepBRUVS were deployed over a 3-day period, during which they recorded between 11 and 15 1-hour sampling events each.
These data were collected as part of a National Environmental Research Program (NERP) Marine Biodiversity Hub project (Theme 1 National Monitoring Evaluation and Reporting, Project 2 Analysis of approaches for monitoring biodiversity in Commonwealth Waters) undertaken in the Solitary Islands Region in August 2012. The Solitary Islands Key Ecological Feature (KEF) field survey had two broad objectives: 1) deploy and demonstrate various non-destructive field methods and 2) compare sampling patterns. These data comprise those collected using stereo-Baited Remote Underwater Video (stereo-BRUV). Four sixty minute stereo-BRUV drop replicates were deployed at two sites at each of five locations: 40 Acres Reef, Split Bommie, Patch, South and Relic Reef. There were 40 drops in total (4 x 2 x 5). An additional 23 drops were deployed at one of the locations (40 Acres Reef) to examine spatial autocorrelation.

The aim of this theme is to develop a bluepint for the sustained monitoring of the South-east CMR Network. The particular aims of the survey were twofold; 1) to contribute to an inventory of demersal and epibenthic conservation values in the reserve and 2) to test methodologies and deployment strategies in order to inform future survey design efforts.

This resource contains the video and stereo still image data collected using a towed system (towed stereo camera system - TSCS). The TSCS was deployed using a probabalistic and spatially balanced survey design called Generalized Random Tessellation Stratified (GRTS). Habitats on the shelf were identified in a previous multibeam survey and consisted of 'mixed reef' (containing patchy reef) and sand. Mixed reef habitat was targeted in this survey (9 GRTS mixed reef sites versus 3 sand sites). Two roughly perpendicular TSCS tows were performed in each of those shelf GRTS sites. On the slope, down-slope (150-500 m depth) transect sites were classified by proportion of hard, soft and mixed bottom types based on multi-beam sonar (MBS) backscatter data. Transects with higher proportion of hard substrates were chosen using a GRTS approach. 7 transects were completed in the Flinders CMR, 5 transects in the adjacent Cape Barren Fisheries closure and two targeted transects were completed in a canyon to the north, where large coral bycatch had been reported from fisheries.
