    CSIRO holds hard copies of longline data (in Japanese) from two Fisheries High Schools: Misaki Fisheries High School, 1969–2000; Shonan Maru (570 pp). Sakai Fishery High School, 1969–1997; Wakatori Maru (324 pp). These reports were provided by the Tokyo University of Fisheries library, where they appear under the titles Josen Jisshu Hokokusho Shonan Maru and Josen Jisshu Hokokusho Wakatori Maru in OPAC. The information contained in these reports relates to the operation of tuna longlines, and includes fishing effort, oceanography and catch composition, and is reported by individual set. Shark are reported only as a general category in both these data sets. The Shonan Maru appeared to make several voyages each year of 1–2 months duration. Examples of translation sheets are included with the hard copies.

    CAT Scans (Computerized Axial Tomography) of Deep Sea Fish: - Orange Roughy - Icefish (Smoothed and sharp images) - Blue Grenadier - Oreo Dories (Spiky, Smooth and Warty) - Warehou. All images were recorded at the Royal Hobart Hospital between 2000 and 2007. The images are in black and white, with mm resolution, from which it is possible to extract density and size measurements. The images are stored in the Digital Imaging and Communications in Medicine (DICOM) format. Added 5th June 2014: zipped datasets (CT-Scan data files of Orange Roughy) have been made publicly available. To view the datasets, download and unzip the files, then copy all contents on a CD, to view the data, use the viewer application PCVCDVW.EXE from the CD in the subdirectory CDVIEWER. Note that the viewer application only runs from a CD.

    This dataset consists of sea mullet tagging log sheets from 1954 to 1956 and tag recovery log sheets from 1954 to 1958. The data was collected from Lake Macquarie.

  • Fish and shark assemblage data are being obtained from the analysis of Stereo-BRUV footage captured in May 2014. Data is comprised of raw camera output stream files (.MTS) for 272 Stereo-BRUV drops in shallow water (~10m) between Exmouth and Dampier, Western Australia. Files are less than 1.9GB and total approximately 10TB. Videos are structured within Stereo-BRUV drops (identified with an OpCode i.e. NCB1-NCB272) with a left and right camera folder within each drop. Videos are lodged with the iVEC Data Store - https://data.ivec.org The Pilbara Marine Conservation Partnership (PMCP) was an initiative designed to enhance the net conservation benefits of the globally-significant coral reef ecosystems of the Pilbara (Western Australia) by providing an assessment of the condition and trajectory of key ecological values. These assessments were designed to inform and complement existing governance and management arrangements and the PMCP is intended to provide ongoing advice and assessment for conservation efforts in the region, providing lasting benefits. The PMCP concept is based on three core ecological components, namely: Coral Reef Health - concentrating mainly on habitat forming primary producers. Fish and Sharks - their community structure, interactions and impacts on lower trophic levels. Environmental Pressures - physical and anthropogenic factors that influence the condition of reefs and associated biota.

    From April 2007 to June 2009, six field trips were undertaken to investigate the elasmobranch faunal composition of the Ningaloo Marine Park (NMP), determine the distribution and abundance of species, and examine the habitat utilisation, movement patterns and activity space of selected key species. Dive and longline surveys, passive acoustic telemetry and satellite tracking were used to collect data. Of interest to management, was whether existing sanctuary zones were effective for elasmobranchs as well as the location and timing of aggregation sites reported for some species. Satellite tagging data: Two types of platform transmitter terminals (PTTs) were used, Wildlife Computers (Redmond, USA) smart position or temperature transmitting tag (SPOT4 or SPOT5) and SPLASH tags. Longline survey data Longline fishing was used to survey elasmobranchs outside the reef and was carried out from the Western Australia Fishery Department vessel RV 'Naturaliste'. A total of 111 longline sets were made between Three Mile Camp towards the southern extremity of the Marine Park, to northeast of the Muiron Islands outside the northern limits of the Park; the distribution of these sets are shown in the thumbnail. Of these 111 sets, 17 were in sanctuary zones and 94 in non-sanctuary zones (in the thumbnail picture the hatched areas are sanctuary zones). Lagoon and reef edge dive survey data Snorkel and SCUBA underwater visual surveys were conducted as part of four field trips to Ningaloo in April and June 2007 and August and December 2008. The June and August surveys were restricted to the reef edge on SCUBA, while the April and December surveys were mainly on snorkel and in the lagoon. While the original intention was to provide coverage through the different seasons, poor weather conditions coincided with most of the planned fieldwork (including cyclone 'Nicholas') resulting in re-scheduling of some trips. A total of 137 sites were surveyed between Vlaming Head on the northeast of the Cape to Gnaraloo in the southern part of the Marine Park (see thumbnail picture). Of these surveys, 89 were in sanctuary zones and 48 in non-sanctuary zones (sanctuary zones are shown as hatched in the picture). Acoustic data Elasmobranchs were tagged with acoustic tags and subsequently monitored with acoustic receivers (Vemco VR2, VR2W and VR3) moored on the seabed that constitute the Ningaloo Reef Ecosystem Tracking Array (NRETA). This array is part of the nationwide network of marine acoustic monitoring, the Australian Acoustic Tagging and Monitoring System (AATAMS). A total of 96 acoustic receivers are deployed at Ningaloo Reef between Coral Bay and Tantabiddi. A total of 56 acoustic tags were deployed on six species of sharks and three species of rays in the Ningaloo Marine Park in February 2008. Data is accessible through the IMOS AATAMS website 11 Nervous Sharks (Carcharhinus cautus) 10 Giant Shovelnose Rays (Glaucostegus typus) 9 Blacktip Reef Sharks (Carcharhinus melanopterus) 9 Grey Reef Sharks (Carcharhinus amblyrhynchos) 8 Cowtail Stingrays (Pastinachus atrus) 4 Porcupine Rays (Urogymnus asperrimus) 4 Lemon Sharks (Negaprion acutidens) 1 Tiger Shark (Galeocerdo cuvier) 1 Whitetip Reef Shark (Triaenodon obesus)

    This record describes the datasets collected from the development of a Gene Tagging Tool for the Regional Tuna Tagging Programme (RTTP) which is managed under the auspices of the Indian Ocean Tuna Commission and genetic tagging studies. The aim is to quantify population structures and migratory dynamics which are currently poorly understood. The use of SNP markers lend themselves easily to routine and inexpensive ($10-$20 per fish) screening methodologies. The stock assessment advice is used to assist in the conservation and optimal economic use of this resource. This record describes the datasets collected or resulting from the outcome of the programme.

    This dataset stores information on the diet of pelagic fishes (tuna and swordfish). The samples and data have been collected seasonally from various sources (fishers on commercial, recreational and chartered vessels as well as CSIRO staff and observers) since 1992. Keywords: Stomach contents, diet, tuna, swordfish.

    The CSIRO hard parts archive comprises collections of otoliths, vertebrae, scales and fin spines from tuna and billfish species, and a supporting database. The archives are a resource for research on age and growth, migration, stock structure and physiology. The specimens have been collected from large pelagic species including southern bluefin tuna (SBT), yellowfin tuna, bigeye tuna, albacore tuna and broadbill swordfish. By 2011, SBT otoliths in the collection numbered 31,416. The physical archives are located at CMAR in Hobart. Associated with the archive is a database containing: - The catch and specimen data related to the hard parts samples. - The results of research using the hard parts including historical and ongoing age and growth studies and otolith chemistry projects. - A link to the Tag Database that holds information on the tagging of the same species.

    Saxon Progress was the industry catcher vessel working in tandem with the Southern Surveyor during the July-August 1999 orange roughy research voyage at St Helens Hill and St Patricks Head. The acoustic system comprised a Sonardata Echolistener unit that digitised and recorded the output of the Furuno 28kHz commercial fisheries sounder. Related datasets: Demersal trawl data collected by the Saxon Progress during the survey; Acoustic and biological data collected by the Southern Surveyor during this same survey period - see separate Marlin entry.
