Fish Meal vs Poultry By-Product Meal — Aqua and Pet Food
Fish meal remains the gold-standard concentrated animal protein for aquafeed, starter piglet and premium pet food, but supply is finite and priced accordingly. Poultry by-product meal (PBM) is the industry's most credible substitute — cheaper, scalable and increasingly accepted in salmon, shrimp and pet food formulas.
Fish meal (60–70% CP)
- Best amino-acid profile — high lysine, methionine, taurine
- Rich in EPA and DHA omega-3s (species-dependent)
- Excellent palatability and digestibility
- Trusted in salmon and shrimp starter diets
- Highest cost per MT of common animal proteins
- Sustainability and IUU-fishing scrutiny
- Regulatory limits in EU salmon feed pushing lower inclusion
- — Marine species starter diets (shrimp PL, salmon smolt)
- — Premium pet food positioning
- — Aquafeed formulas requiring omega-3 baseline
Poultry by-product meal (60–65% CP)
- USD 400–900/MT cheaper than fish meal
- Scalable, non-fishery-dependent supply
- Good amino acid profile (excluding taurine)
- USDA/EU spec grades widely available
- Regulatory restrictions in some jurisdictions (species barriers)
- Variable ash content — spec discipline critical
- Requires synthetic taurine and DHA supplementation in aquafeed
- — Grow-out aquafeed formulas with fish oil supplementation
- — Mid-tier pet food and pig starter
- — Buyers replacing 30–70% of fish meal in existing formulas
| Criterion | Fish meal (60–70% CP) | Poultry by-product meal (60–65% CP) |
|---|---|---|
| Typical landed cost / MT (2025 indicative) | USD 1,650–2,100 (Peruvian anchovy, super-prime) | USD 800–1,100 (US, Brazil, EU spec grade) |
| Cost per unit digestible lysine | Baseline; premium justified in specific applications | Typically 40–55% cheaper per unit dLys |
| Metabolizable energy (poultry) | ~3,000 kcal/kg | ~3,200 kcal/kg (fat-dependent) |
| Quality risk to monitor | TVN, histamine, oxidation (peroxide value), salmonella | Ash content, salmonella, TVN, pepsin digestibility |
Fish meal remains defensible where taurine, DHA and starter palatability drive performance premiums. In grow-out diets, PBM substitutes 40–70% of fish meal with synthetic taurine and fish-oil-only omega-3 provision at large cost savings. Never compromise on TVN, histamine or salmonella specs whichever origin you choose.
