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.
Short answer: Fish meal carries a higher and better-balanced amino-acid profile with strong palatability and digestibility for carnivorous species, while poultry by-product meal is usually cheaper, less volatile in price and more locally available but varies far more between producers in ash, digestibility and freshness. Partial substitution is common in aqua diets; the practical limits are species, life stage, feed-law restrictions in your market, and the consistency the supplier can document lot to lot. Confirm any substitution and inclusion rate with your nutritionist before changing a diet.
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 (indicative only — confirm against live offers) | 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.
