European Grayling Movement and Environmental Data from the Vöckla River, Austria, 2025

April–July 2025 telemetry and environmental data for 147 European grayling in the Vöckla River, Austria. The dataset includes daily fish positions, water level, and temperature, collected via radio-tagging and mobile tracking surveys. It was created by Maxim Teichert and released under a CC-BY-4.0 license.

Use Cases

• Modeling fish movement patterns based on daily position data relative to the release site.
• Analyzing the influence of daily water level and temperature on grayling behavior.
• Comparing survival and movement between hatchery-reared (acclimatized and direct-release) and wild-captured fish groups.
• Investigating the relationship between fish body measurements (length and weight) and movement behavior.

Strengths

• Includes data for 147 individually tagged fish across three distinct experimental groups.
• Covers a 14-week monitoring period with 33 mobile tracking surveys, providing temporal depth.
• Combines biological telemetry data with daily environmental variables (water level and temperature).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (194.7 KB), indicating limited scope and sample size.
