Eyer Aquaculture ROI calculator
Farm profile
HOG tonnes (licensed capacity)
10 000 t
Head-on gutted weight — standard Norwegian licence metric. Single MAB licence: ~780 t standing biomass → ~3,000–4,500 t HOG/year. Small operators: 3,000–10,000 t. Large companies: 200,000–230,000 t HOG.
Active cages / tanks
24
Adjust until HOG/cage matches your stocking. Open net pen: 500–1,500 HOG t/cage. SCC: 300–900 t/unit. RAS: 100–500 t/tank.
Implied capacity / unit
417 t
Sensor streams per cage
14
O₂, temperature, CO₂, salinity, feed cameras, behaviour cameras, biomass cameras, current meters, lice counters, feed silo load cells, equipment status. Basic open net: 6–10. Well-instrumented: 15–25. RAS: 25–35+.
Total active streams
336
Note: This total does not dynamically impact the ROI calculation, as the operational effort estimate relies strictly on 'Analyst hours / cage / week'.
Farmgate price (NOK/kg)
78
Average NOK/kg HOG received after quality grading and contracts. Used to value mortality losses. 2023–2024 average: NOK 70–95/kg. The price premium below is additional to this — they do not overlap.
Manual alternative cost ▶
Cost per analyst (NOK)
850k
Fully loaded: gross salary + employer social security (~14.1%) + pension + benefits. Data analyst or fish biologist: NOK 750k–1,000k. Senior specialist: NOK 1,000k–1,300k.
Analyst hours / cage / week
7.0 h
Hours/week an analyst spends reviewing sensor data, identifying anomalies, and forming recommendations for one cage. Lightly monitored: 2–4 h. Heavily instrumented: 8–12 h. Scales with sensor density in this model.
Data platform & tooling / yr (NOK)
100k
Fixed annual cost for analytical software licences layered on top of existing SCADA and sensor infrastructure. Covers data historians, SCADA visualisation, and BI tools. Small operators: NOK 50k–200k/year. Larger: NOK 300k–1,000k/year.
Eyer impact (Assumptions) ▶
Baseline mortality rate
17%
Annual mortality as a percentage of stocked fish. Open net: 15–20% (avg 17%) — driven by lice, AGD, CMS, PD. SCC: 10–14%. RAS: 5–10%. Defaults update automatically.
Mortality reduction with Eyer
1.0 pp
Expressed in percentage points (pp). For example, dropping from 17% to 16% is a 1 pp reduction. Driven by earlier detection of health events and oxygen depletion.
Feed cost reduction
1.0%
Expressed as a percentage (%) reduction in total annual feed cost. Driven by improved feeding precision — detecting satiation earlier, reducing waste. Feed is 45–52% of COGS.
Price premium (NOK/kg)
1.50
Additional NOK per kg above current farmgate price, from better harvest timing. Applied to full harvested volume. 1–3 NOK/kg is realistic.
Opex reduction (treatments)
3.0%
Expressed as a percentage (%) reduction in non-feed operating costs — lice treatments, veterinary costs, etc. Non-feed opex is around 20–24% of total COGS.
Manual capture rate
50%
Share of the full operational impact a well-staffed manual team could achieve. Limited by working hours (no 24/7 coverage) and reaction lag. 50–70% typical.

Total Eyer Value

1. Manual alternative cost avoided ▶
—
Annual cost of staffing, platform, and overhead to approximate Eyer's insight manually.
2. Incremental operational uplift ▶
—
Full impact (—) minus manual capture (— = —). Remainder is value only Eyer delivers.
3. Site P&L Simulation (High-level) ▶
—
Aggregates Eyer's incremental impact across core operational accounting layers.
COGS benchmarks: ~NOK 42/kg (open net) / ~NOK 60/kg (SCC) / ~NOK 72/kg (RAS). Mortality defaults: 17% (open net), 12% (SCC), 7% (RAS). FTE load: analyst hours × sensor density ÷ 1,680 productive hrs/year. Mortality reduction in pp; feed and opex reduction in %. Values are indicative estimates only.
