NESP MBH A1: Northern Australian Elasmobranch Fishing and Telemetry Data

Surveys from 2016 to 2026 collected sampling effort, catch records, biological data, and water quality data for elasmobranchs in northern Australian rivers, estuaries, and coasts. The data was gathered under the NERP and NESP Marine Biodiversity Hub projects using gillnets and rod-and-line in the Top End and Kimberley regions. Selected animals were tagged for acoustic telemetry, and tissue samples were taken for molecular analyses.

Use Cases

• Population genetics analysis based on collected tissue samples.
• Movement ecology and habitat use modeling based on acoustic telemetry tagging data.
• Catch-per-unit-effort (CPUE) analysis based on fishing survey effort and catch records.
• Water quality impact assessment on elasmobranch distribution based on recorded environmental parameters.

Strengths

• Data collection spans multiple projects (NERP and NESP Marine Biodiversity Hub) over a long period.
• Includes multiple data types: biological samples, telemetry tags, and environmental water quality.
• Surveys cover two distinct geographic regions: the Top End (NT) and the Kimberley (WA).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, focusing only on northern Australia.
