Analytics
The cycle in numbers — what the fleet protected, what the hatchery returned, and what NEREID flagged. Trends are rolling; comparison is across the breeding zones.

Breeding Zone Comparison
Output and condition across the culture zones, normalised for stock at risk. Spawn index reflects the hatchery contribution per zone.

| Cichlid Hall | Freshwater | 1 | 96 | 62% | 96.4% | |
| Livebearer Racks | Freshwater | 1 | 118 | 71% | 95.8% | |

What NEREID flags. The ops layer raises an analytics alert when a trend breaks its envelope — a spawn index falling two cycles running, a bycatch figure spiking against stable fleet posture, or a zone's readiness diverging from its cohort. Flags route to System Status and the dawn sweep, never to a quiet log.
Method note. Series shown are representative rolling aggregates curated by Marine Science; live per-channel figures stream on the command wall and reconcile against the Universal Marine Registry each cycle.
