Tasmanian recreational abalone fishing data compiled by IMAS covers eight assessment areas from the 2002/03 to 2024/25 seasons. The data includes estimated catch in kilograms and numbers, estimated effort in fishing days, and catch rates for both blacklip and greenlip abalone species. Data collection is based on a phone-diary survey of randomly sampled license-holders conducted between November and April.
Use Cases
- Analyzing long-term trends in recreational abalone catch based on the 23-year time series
- Comparing fishing effort and catch rates between the eight assessment areas
- Modeling population dynamics for blacklip and greenlip abalone species based on catch estimates
- Evaluating the effectiveness of the phone-diary survey method for monitoring recreational fishing activity
Strengths
- Data spans 23 fishing seasons from 2002/03 to 2024/25
- Includes estimates for two distinct species: blacklip and greenlip abalone
- Covers eight distinct assessment areas within Tasmania
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Data is provided in PDF, PNG, and HTML formats, which may require extraction for analysis
