Hoplostethus atlanticus (Orange Roughy) length weight data, Australian waters (1987-2012)

Latest version published by CSIRO Oceans and Atmosphere on May 28, 2020 CSIRO Oceans and Atmosphere

The biological data were obtained between 1987 and 2013.Over this period the survey objectives varied as did the technology of the monitoring and sampling programmes, including differences in trawl gear and fishing vessel. For most survey years fish were collected from commercial trawling vessels using a standard commercial orange roughy net fitted with 40 mm cod-end liners. Exceptions were 1987 and 1992, when an Engel high rise bottom trawl, with a 40 mm cod-end liner, was deployed from the CSIRO’s research vessel. Biological sampling was associated with acoustic surveys in most years and used primarily for species identification,and to collect representative samples from aggregations of fish for length, weight, sex, gonad stage or retaining otoliths for ageing.The protocol was to collect 200 sexed fish lengths and 50 otolith pairs per trawl. Demersal trawls were targeted on aggregations of orange roughy determined by the vessel’s acoustics but catches were limited in many years by the available vessel quota (using windows in the trawl, or fishing on the side of large aggregations).

Data Records

The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 536 records. 2 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

  • Occurrence 

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.
