Larval Rearing Density (LRD)
Stocking density in the larval-rearing tanks. The dial the hatchery turns to trade throughput against survival; crowding the most fragile stage is the fastest way to lose a whole cohort.
Threshold Bands
| Band | Range | State |
|---|---|---|
| Optimal | ≤ 30 | OK |
| Crowded | 30–60 | WARN |
| Overstocked | > 60 | CRIT |
Formula
Stocked larvae ÷ working rearing volume per cohort tank.
