This dataset shows details of foreign squid fishing in Australian waters from 1977 to 1987. The data is sourced from daily fishing returns recorded by the foreign fishers while at sea. Data provided is by individual fishing operation. Weights are estimates only. Appropriate use and limitations of the data == The catch weight data in logbooks are estimates only which have been recorded by fishers while at sea. Fishers usually cannot accurately weigh fish at sea, so the estimated weights are mostly based on volume (for example, the size and number of boxes of fish caught). At this time, positions are also estimates as GPS navigation systems did not exist. Disclaimer -- The data provided by AFMA is raw (unprocessed) data and may contain errors or be incomplete. Errors are more likely in the species caught in low volumes. AFMA makes no warranty or representation that the data is accurate or complete. Those who choose to use this data should make their own enquiries as to its accuracy and completeness and AFMA assumes no liability for any errors or omissions in the data provided, or for any decision by a person who chooses to rely on the data.

This record contains fisheries statistics, History of Marine Animal Populations, trawling, overfishing from the Australian fishing industry between 1937 and 1943.

##Description While at sea, Commonwealth fishers must record all catch and effort in their AFMA daily fishing logbooks. This dataset shows the annual fishing effort by fishery and gear, that fishers have recorded in their logbooks for Commonwealth fisheries managed by the Australian Fisheries Management Authority (AFMA). Location of effort within a fishery is not included. These data are sourced from AFMA daily fishing logbooks, which fishers complete while at sea. Location of effort within a fishery is not included. Fishing effort is measured differently depending on the fishing method used. In this dataset we provide the most common measures that are used by scientists. ##Appropriate use and limitations of the data The effort data in logbooks are estimates only, which have been recorded by fishers while at sea. Effort data are used in combination with catch data, spatial data, and other relevant information (such as independent surveys) to inform stock assessments. These data may differ from other summations over the same time-period (such as stock assessment reports) due to differences in data handling procedures. For example, scientists may standardise effort for assessments to account for issues such as changes in gear efficiency, catchability of fish and skipper expertise. They may also filter out effort from their assessments because of data quality issues. Care should be taken when interpreting trends in this data because there are many factors that can affect effort each year. Catch quantities can be impacted by management measures such as closures of fishing areas or reducing boat numbers. Similarly, changes in market demand can change fishing decisions and affect effort. ##Disclaimer The dataset provided by AFMA is comprised of raw (unprocessed) data as received from fishers, and may contain errors or be incomplete.

This dataset comprises catch compositions and trawl locations from a cruise of the Russian fishery research vessel "Alba" carried out in Australian waters in October 1973, containing 28 demersal trawls from the Great Australian Bight, W Western Australia Coast, and Australian North West Shelf. Most records include catch composition by species (presence/absence but not weight), also some data on length frequency, maturity and diet of commercially important species. The data were obtained by exchange with Soviet scientists in the mid 1990s and has had CSIRO species codes incorporated. The dataset is now in an Oracle database in Hobart, and analyses/summaries of the data are given in the accompanying report (see References). A MS Access version of the dataset has been compiled for use within the North West Shelf-JEMS study. This version is available on-line for researchers in the NWS-JEMS study (see data links). The data are also accessible to authorised users via CMR's "Data Trawler" application. A username and password is required to access this dataset.

This dataset comprises catch compositions and trawl locations from a cruise of the Russian fishery research vessel "Raduga" carried out in Australian waters between June and November 1972, containing 380 demersal trawls from the Great Australian Bight, SW, W, NW and N Western Australia coast, Northern Territory coast, and Gulf of Carpentaria. Most records include catch composition by species (presence/absence but not weight), also some data on length frequency, maturity and diet of commercially important species.

The datasets contain summaries of Western Australia logbook data on catch and effort distribution for commercial fisheries in state marine and estuarine waters. The logbook data has been recorded and submitted to WA Department of Primary Industries and Regional Development by commercial fishers. The data are aggregated to produce summaries of total catch and effort by fishery at a 0.1 degree resolution where 5 boats or more operate. For areas where less than 5 boats operate the data is shown as confidential. The data was mapped using 5 year - financial year periods; 2003/04 to 2007/08, 2008/09 to 2012/13, 2018/19 to 2022/23, and 1 year; 2022/23.

This dataset comprises catch compositions and trawl locations from a cruise of the Russian fishery research vessel "Raduga" carried out in Australian waters between August 1966 and March 1967, containing 454 demersal trawls from the Tasmania coast, Bass Strait, South Australia coast, Great Australian Bight, Western Australia coast and North West Shelf. Most records include catch composition by species (presence/absence but not weight), also some data on length frequency, maturity and diet of commercially important species.
