MTSRF Project 4.8.1 data from the Australian Ocean Data Network assesses the benefit of no-take (green) zones as a recruitment source for reef fish. The study involved genetic analysis of 1342 adult stripey snapper and 483 collected juveniles from 16 sites around the Keppel Islands. Approximately 30% of juveniles were successfully assigned to sampled parents, revealing dispersal patterns between green and blue zones.
Use Cases
- Modeling larval dispersal patterns based on genetic parentage assignments.
- Evaluating the effectiveness of no-take zones as recruitment sources based on juvenile assignment rates.
- Analyzing population connectivity between protected and fished areas based on dispersal percentages.
Strengths
- Includes genetic data from 1342 adult fish and 483 juveniles, providing a substantial sample for analysis.
- Quantifies recruitment outcomes with specific percentages: ~30% of juveniles assigned to parents, with 62% dispersing into blue zones.
- Data collection is tied to a specific research project (MTSRF 4.8.1) with published references, providing context.
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 Keppel Islands study area.
