Optimal Range: 30 to 800
Direction: Higher is desirable ↑
Form: OptimalRange

Scoring Curve

This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context. The scoring engine uses 3 benchmarks together — the OptimalRange form drives the primary score, while 2 guard(s) constrain the result.

Evidence & Context

Optimal Range: 30 – 800 μS/cm Operating within this range ensures that a freshwater aquaculture facility uses water that is both physiologically supportive of its stock and reflective of a high-quality, non-degraded natural ecosystem.

Metric Definition:

Optimal operational range of Electrical Conductivity (EC) for sustainable freshwater aquaculture

Benchmark Definition:

The optimal range of electrical conductivity that balances physiological needs and ecosystem health in freshwater aquaculture.

Justification:

Synthesized from lower and upper boundaries to define a functional range for sustainable aquaculture.
