Every harvested batch this quarter: which defects push fish below superior grade, by pen and site, and the value lost.
Filters persist across every tab. Click any bar, dot or row to drill down. Rate rankings are gated to ≥30 batches. Chips show active filters — click to remove.
No rows match these filters.Nothing is being calculated, because there is nothing to calculate from — a rate over
zero rows is not zero, it is undefined, and showing you a number here would be a wrong one.

Downgrade rate by week — p-chart with control limits
Weekly downgraded-batch proportion vs the centre-line and ±3σ limits (limits widen when a week harvests fewer batches). Points outside the band are special-cause — a sea-lice treatment, a bloom, a crowding incident — not routine variation. Limits recompute on your current filter; n small ⇒ wide limits.

Superior-grade yield by pen
Yield = 1 − downgrades ÷ batches, per pen, grouped in site order · coral bar = worst pen · min. 30 batches

Batches traced
–
to a feed supplier lot
Downgrade rate by feed supplier lot
Worst 15 lots by downgrade %, min. 30 batches · redder = worse · feed lot is the strongest upstream input signal you can trace
Lot volume vs downgrade rate
Each dot a feed lot · x = batches fed · y = downgrade % · top-right = high-volume & high-downgrade = raise with the supplier first

Value loss Pareto — by reason
Total £ lost by reason (bars) + cumulative % · this re-ranks against the count Pareto — the most frequent defect is not the most expensive one

Concentration (Gini)
–

Open actions

corrective actions raised
Action closure

Fix first
–
highest frequency × value
Defect concentration — reason × site
Downgrade count per reason × site · darker = more · is it one cell or spread across the estate?
Corrective-action priority
Each dot a downgrade code · x = frequency · y = value lost · top-right = fix first · size = open actions

Downgrade rate by harvest shift
Crowding and pumping at night bruises more fish than it does at first light
Downgrade rate by smolt intake batch
Production cycle, oldest intake first · longer at sea = larger, more mature fish = more downgrades · dashed = group average
Downgrade rate by QC grader
Find-rate per grader vs the group average (dashed) · variation in grading, not necessarily fault — but a grader well below the line is passing what others catch · min. 30 batches
