Northern Territory Commercial Fisheries Catch and Effort Summaries

Aggregated logbook data from commercial fisheries in Northern Territory marine and estuarine waters, mapped across several multi-year periods from 2003/04 to 2022/23. The data, submitted to the NT Department of Agriculture and Fisheries, shows total catch and effort at a 1-degree resolution where five or more boats operate. Data from areas with fewer than five boats is withheld for confidentiality.

Use Cases

• Analyze spatial trends in commercial fishing effort based on aggregated logbook data.
• Assess total catch distribution by fishery across multi-year financial periods.
• Identify areas of high fishing activity where data is publicly reported versus confidential zones.

Strengths

• Data is aggregated across multi-year periods, including 2003/04-2007/08, 2008/09-2012/13, and 2018/19-2022/23.
• Spatial resolution is specified as 1-degree grid cells.
• Confidentiality protocols are described, with data withheld where fewer than five boats operate.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data freshness should be verified as the last update timestamp is far in the future (2026-06-08).
