AUS-TMI-AQU-DNA General Moderate confidence

Benchmark Value

80 count

Direction: Higher is desirable ↑

Form: MinimumOnly

Scoring Curve

This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context.

Evidence & Context

a target could be the detection of a fish community exceeding 80-100+ genera and a total metazoan community profile spanning multiple phyla, demonstrating clear differentiation from and enrichment over reference non-structured sites.

Metric Definition:

eDNA-detected fish community richness (number of genera)

Benchmark Definition:

A diverse eukaryotic community profile detected via eDNA metabarcoding of water samples that is significantly richer and compositionally distinct from adjacent, unstructured habitats in tropical and subtropical maritime island aquaculture systems.

Justification:

Synthetic benchmark derived from analogous systems (Australian oyster reefs and natural reef systems) where habitat complexity drives biodiversity.
