By 2024, farmed fish has captured nearly 60% of the global seafood market, yet many chefs still miscalculate its true cost impact. Purchase prices tell only part of the story - yield rates, trimming loss, and quality positioning all affect your bottom line. The math behind choosing farmed versus wild-caught involves more variables than most operators realize.
The price difference between farmed and wild-caught fish
Farmed fish typically runs cheaper than wild-caught, but the calculation extends far beyond simple per-kilo pricing.
? Example price difference:
Salmon fillet (200g portion):
- Wild-caught Norwegian salmon: €28/kg = €5.60 per portion
- Farmed salmon: €22/kg = €4.40 per portion
Difference: €1.20 per portion
Factors that affect your real costs
Purchase price represents just your starting point. These variables determine actual costs:
- Trimming loss: Wild-caught often requires more trimming due to irregular sizing
- Shelf life: Farmed fish typically lasts longer, reducing waste
- Consistency: Farmed fish delivers more uniform portions
- Seasonal fluctuations: Wild-caught prices swing more dramatically
Factoring trimming loss into your food cost
Trimming loss can either amplify or reduce farmed fish's price advantage. But here's one of the most common blind spots in kitchen management: operators forget to calculate yield percentages into their actual food costs, leading to margin erosion they can't explain.
? Example trimming loss calculation:
Sea bass fillet (150g portion):
- Wild-caught: €24/kg, 20% trimming loss → €30/kg real price
- Farmed: €20/kg, 15% trimming loss → €23.53/kg real price
Difference after trimming loss: €6.47/kg = €0.97 per portion
⚠️ Note:
Always include trimming loss in your food cost calculations. The formula: Purchase price / (100% - trimming loss%). So with 20% loss: €24 / 0.80 = €30/kg.
Factoring in quality differences
Wild-caught fish carries premium perception that can impact your menu pricing and margins:
- Premium positioning: Wild-caught often supports 10-20% higher menu pricing
- Guest experience: Some diners specifically seek 'wild-caught' options
- Seasonal specials: Wild-caught fits better with rotating seasonal offerings
? Example margin impact:
Same dish, different positioning:
- With farmed: €4.40 purchase cost, €24 menu price = 20% food cost
- With wild-caught: €5.60 purchase cost, €28 menu price = 21.8% food cost
Wild-caught delivers €0.60 more margin per portion despite higher purchase cost.
Seasonal fluctuations and planning
Wild-caught prices swing more due to seasons and catch volumes. This demands different purchasing and menu approaches:
- Fixed menu: Farmed fish offers more price stability
- Seasonal menu: Wild-caught aligns better with changing offerings
- Contract pricing: More feasible with farmed fish suppliers
Choosing farmed vs wild-caught
Your decision depends on concept and target market:
? Choice matrix:
Choose farmed for:
- Fixed menus with stable pricing
- High-volume operations
- Strict food cost targets
Choose wild-caught for:
- Premium market positioning
- Seasonal menu rotations
- Sustainability-focused guests

How do you calculate the real costs of farmed vs wild-caught fish?
Gather purchase prices and trimming loss percentages
Note the price per kilo of both options from your supplier. Measure or ask for the trimming loss percentage - wild-caught often has 15-25% loss, farmed 10-20%. This difference can significantly affect your food cost.
Calculate the real kilo price after trimming loss
Use the formula: Purchase price / (100% - trimming loss%). For example: €24/kg with 20% loss = €24 / 0.80 = €30/kg real price. Do this for both options to compare fairly.
Calculate what this means per portion and per month
Multiply the difference per portion by your average sales. For example: €0.50 difference per portion × 200 fish dishes per week × 4.3 weeks = €430 per month. This shows the impact on your total food cost.
✨ Pro tip
Run a 72-hour side-by-side cost analysis before making permanent switches. Track not just purchase prices, but also trimming waste, prep time, and guest feedback on identical dishes using both farmed and wild-caught options.
