Australian Ocean Data Network collected data on coral recruit survival under controlled fish grazing in December 2023. High-resolution images tracked the size and survival of week-old and month-old coral recruits of three species before and after 24-hour exposure to four fish grazer species and control treatments. The experiment investigated the impact of different grazing behaviors on early coral survival.
Use Cases
- Modeling coral recruit survival thresholds based on size and grazer type.
- Comparing the impact of different fish grazing behaviors ('brusher' vs 'cropper') on algae coverage.
- Analyzing the relationship between recruit age (week-old vs month-old) and mortality rates under grazing pressure.
Strengths
- Data includes high-resolution images for precise size and survival tracking.
- Experimental design includes multiple grazer species and a manual algae removal control.
- Data collection is temporally precise, occurring in December 2023.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified; last updated date is 2026-06-17.
