NESP MBH A1: Northern Australian Euryhaline Shark and Ray Fishing Data

The NESP MBH A1 Euryhaline Elasmobranchs Fishing Database contains sampling effort, catch records, biological data, and water quality data from surveys in northern Australian rivers, estuaries, and coasts. Data was collected under the National Environmental Science Program Marine Biodiversity Hub Project A1 using gillnets and rod-and-line in the Top End and Kimberley regions. Selected animals were tagged for acoustic telemetry, and tissue samples were collected for molecular analyses.

Use Cases

• Modeling population dynamics and mortality based on catch records and tagging data.
• Analyzing movement ecology and habitat use based on acoustic telemetry tagging mentioned in the description.
• Studying population genetics and kinship based on molecular analyses of collected tissue samples.
• Assessing environmental influences on species distribution based on collected water quality data.

Strengths

• Includes multiple integrated data types: catch records, biological data, water quality, and telemetry.
• Covers two distinct geographic regions: the Top End of the Northern Territory and the Kimberley region of Western Australia.
• Data collection supported by two major Australian environmental research programs: NERP and NESP.

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 the specific northern Australian survey areas.
