| Commons Aggregation | Guild |
|---|
| Explanation | Fish spawning aggregation of Lutjanus bohar (red snapper), Epinephelus fuscoguttatus (brown-marbled grouper) and Plectropomus areolatus (square/tailed coral grouper). |
|---|
| Commons Boundaries | Clear boundaries (3) |
|---|
| Explanation | Spawning fish that have clear boundaries while aggregating, the times and locations of spawning are relatively predictable, no-take zones match up with spawning aggregation sites, and where they spill-over fishers are expected not to fish the aggregation (No-take zones not marked out by buoys but identified by spawning aggregation) |
|---|
| Commons Indicator | ["Status of species targeted by fisheries"] |
|---|
| Explanation | These fish are an indicator of fish stocks. These fish species are targeted by fishermen who used to fish at the spawning sites. These spawning sites are now no-take zones. |
|---|
| Commons Unit Size | Small (2) |
|---|
| Explanation | Lutjanus bohar - common length = 76cm
Epinephelus fuscoguttatus - common length = 50cm
Plectropomus areolatus - max length 80cm

| Commons Renewability | Renewable (1) |
|---|
| Explanation | Lutjanus bohar and Epinephelus fuscoguttatus both have minimum population doubling time 1.4 - 4.4 years,
Plectropomus areolatus is much less productive with a minimum population doubling time 4.5 - 14 years |
|---|
| Productivity | Moderately Productive (2) |
|---|
| Explanation | Lutjanus bohar and Epinephelus fuscoguttatus both have minimum population doubling time 1.4 - 4.4 years,
Plectropomus areolatus is much less productive with a minimum population doubling time 4.5 - 14 years |
|---|
| Commons Accessibility | Very accessible (3) |
|---|
| Explanation | These species aggregate at regular sites and times facilitating their exploitation |
|---|
| Commons Heterogeneity | Low (1) |
|---|
| Explanation | Fish come together to spawn so have low spatial heterogeneity when breeding. |
|---|
| Commons Mobility | Medium (2) |
|---|
| Explanation | Not sessile, but not highly migratory, therefore considered to have medium mobility |
|---|
| Commons Spatial Extent | 4 |
|---|
| Explanation | Relatively small size of spawning aggregations but more than one aggregation at different locations along the reef (3 main sites). Estimates for size of Pletropomus SPAG was 3-4 (Wilson et al 2010 SPC Bulletin). |
