These summary cards update when you change the year range above. They are designed to show the scale of losses, the worst and best years, and cumulative pressure from sea lice violations and disease.

This section compares losses as both rate and absolute count. The rate matters for welfare. The absolute count matters for scale. Together they show whether the industry is truly improving or simply getting larger.

ISA remains elevated compared with earlier years, PD has fluctuated sharply, and lice limit violations remain a recurring system-level problem. This section lets users compare the relative weight of each issue over time.

Production growth does not automatically imply welfare improvement. Comparing smolt input, sold biomass, and cleaner fish deployment helps show whether rising scale has been matched by lower losses, or whether losses have expanded alongside production.

Click a region to see its year-by-year loss rate and production. Troms and Finnmark were administratively combined in 2020–2022, so they appear as one county for those years and as separate counties from 2023 onward.

Total first-hand sales value for all farmed salmonids (salmon, rainbow trout, trout) climbed from 7.6 billion NOK in 1999 to a peak of 113 billion in 2023. Most of that growth came from price, not volume — the average price per kg rose from 21 NOK in 1999 to 69 NOK in 2023. This is official first-hand price (førstehåndspris), meaning the price processors pay farms, not the consumer retail price. Use the year range controls above to focus on any period.

The key question is not only whether losses rise or fall in a single year, but whether the overall system is trending toward better outcomes. Users should be able to see whether lower losses are sustained, whether disease pressure changes, and whether production growth comes with a proportional welfare cost.
