    This biological overview for the Southern Surveyor voyage SS 07/2005. The voyage took place off the Western Australian Coast during July August 2005. This dataset has been partly processed and has not yet been archived within the CSIRO Marine and Atmospheric Research Data Centre in Hobart. Additional information regarding this dataset is contained in the cruise report for this voyage and/or the data processing report. On this cruise pigments and chlorophyll a were collected by Neale Johnston and later processed at CMAR, Hobart by Pru Bonham.

    School shark pupping areas in inshore waters of Tasmania and Victoria identified by Olsen in the 1940s and 1950s were re-sampled using gillnets & longlines from 1991-97. Current catch rates are much lower at all sites and pups are apparently no longer present at some sites. Additional sampling of mainly inshore embayments in Tasmania and Victoria failed to locate significant new pupping grounds of school shark. Limited sampling in South Australia and Western Australia failed to catch school shark pups. Relatively few gummy shark pups were caught anywhere in this study; no significant pupping grounds were located and pupping appears to take place over scattered locations in inshore waters. Catch data includes a wide variety of sharks, rays and teleosts species, the most numerous being: Squalus megalops, Platycephalus bassensis, Squalus acanthias, Pseudophycis bachus, Aldrichetta forsteri, Mustelus antarticus, Callorhynchus milii, Galeorhinus galeus, Tracurus declivis, Cephaloscyllium laticeps, Neosebastes scorpaenoides, Platycephalus richardsoni, and Sillago bassensis. The fish catch data was taken from school shark nursery areas in Tasmania and Victoria, this study is split into 2 portions, first a 12 month study (91-92), followed by a multi-year study (92-97). Further documentation was added in March 2014, see below.

    This is a biological overview of data collected on Southern Surveyor voyage SS 09/2004. The voyage took place off the east coast of Queensland in September 2004. This dataset will be processed and archived within the CSIRO Marine and Atmospheric Research Data Centre in Hobart. Additional information regarding this dataset is contained in the cruise report for this voyage and/or the data processing report. For micronekton and zooplankton prey data contact Jock Young, acoustic biomass data was collected and stored by Rudy Kloser. The Phytoplankton biomass and speciation was processed by Lesley Clementson. The Stomach content data is in an ACCESS database, contact Jock Young. Mark Lewis has video from voyage and photographs of deck shots & equipment used during the voyage.

    This dataset contains information on closures collected from various NPF Management meetings, from the 1970's to 2004 (see below). Information was collected on why closures were proposed, evidence presented, and reasons why the proposals were accepted, rejected or modified. Emphasis is placed on obtaining information on why a closure was instigated, and the reasons why closures undergo subsequent modification. Scientific research carried out within or near each closures is also listed. Data were collected for closures that already existed at the time of database creation (2004), and it is planned that data collection will be ongoing, subject to funding and personnel availability. The data collected is linked to an existing GIS database containing spatial information on gazetted closures. Data sources for the historical review included: NORPAC/ NORMAC agendas and minutes, 1982 - 2004; Northern Fisheries Council documentation; Closures Task Force /Closure Committee minutes; Departmental Correspondence; Government Gazettes; AFMA NPF Directions; NPF publications (e.g. Pownall, 1994); Meeting notes kept by some research representatives on the above committees. The project objectives were: a. Identify the reasons for the designation of each closure and any information from research surveys that are available to evaluate the reasoning (including instances where no information exists). b. Develop agreed criteria to classify the different types of closures in the fishery. c. Develop and document protocols and criteria to be used to review (change or remove) an existing closure. d. Develop and document protocols and criteria to be used to establish new closures in the fishery. e. Provide Industry with succinct information that allows the consideration of the implementation, success and future advantage of the current closures.

    38kHz Simrad ES60 acoustic data collected during commercial fishing of spawning orange roughy off the Tasmanian east coast in 2004. Acoustic data is held by the CSIRO Marine Science Acoustic Group (Hobart). Additional data: gps embedded in ES60 .raw files, Wildlife computers MK9 temperature/depth loggers attached to headline of trawl net, AMFA (Australian Fisheries Mangement Authority) observer biological data (species, length, weight, sex, stage)(contact AFMA Observer section), AFMA trawl shot log - filled in by ships officers for each trawl shot, showing catch, location etc (contact AFMA Observer section).

    A study of the scallop resources, advection and settlement of P fumatus in Bass Strait was carried out in Bass Strait and Great Oyster Bay on a series of cruises from 1986 to 1992. Scallop growth and reproduction were also analysed. Vessels used included Merindah Pearl and Dell Richey. Additional data identified in June 2015. See TRIM references in stored data location.
