要求仕様の定め方
- State the grade you need (standard, prime, super-prime, LT / low-temperature) and the species or origin group.
- Define the digestibility expectation, not just crude protein — LT meals command a premium for a reason.
- Specify the antioxidant type and dose, and whether ethoxyquin is permitted in the destination market.
- Fix maximum age at shipment; freshness parameters degrade in storage even in good conditions.
- Confirm whether the destination requires a veterinary health certificate and an approved-establishment number.
重要な規格項目
| 項目 | 一般的な要求値 | 買い手にとっての意味 |
|---|---|---|
| Crude protein | 62–68% | Grade definition and the basis of price adjustment. |
| TVN (total volatile nitrogen) | ≤ 120 mg/100 g | The main raw-material freshness indicator; high TVN signals decomposed feedstock. |
| Histamine | ≤ 500–1,000 ppm by grade | Biogenic amine associated with gizzard erosion and reduced performance. |
| Free fatty acids | ≤ 7–10% | Oil hydrolysis indicator; predicts rancidity development in storage. |
| Peroxide value / TBARS | Low and antioxidant-protected | Oxidative status; drives palatability and vitamin destruction in the finished feed. |
| Fat | 6–11% | Energy contribution and oxidation exposure. |
| Moisture | ≤ 10% | Microbial and self-heating risk above the limit. |
| Ash / salt / sand | ≤ 16% / ≤ 3% / ≤ 1% | Detects mineral dilution and adulteration. |
| Salmonella | Absent in 25 g | Legal requirement in most import markets. |
一般的に要求される認証
- — GMP+ B2 or equivalent feed-safety certification for the producing plant
- — IFFO RS (MarinTrust) responsible-supply certification where sustainability is required
- — Approved-establishment listing for the destination market's veterinary authority
- — MSC or fishery-specific chain of custody where the customer demands traceable origin
- — Dolphin-safe / by-catch declarations where relevant to the end market
確認すべき試験報告書
- — Certificate of Analysis per lot including TVN, histamine, FFA and antioxidant residual
- — Salmonella certificate with the sampling plan and laboratory accreditation
- — Veterinary health certificate matching the exact lot and container numbers
- — Heavy metals (cadmium, mercury, lead, arsenic) and dioxin/PCB screening
- — Independent surveyor sampling report — composite sampling, not a single grab
包装の検討事項
- — 50 kg or 25 kg PP bags with an inner liner for moisture control
- — Big bags for mechanised plants; confirm the liner and UV rating
- — Bulk only where the receiving plant has closed intake and rapid turnover
- — Bag marking must carry lot, production date and antioxidant declaration
輸送の検討事項
- — Self-heating cargo: confirm IMDG/IMSBC classification and required antioxidant certification before booking
- — Ventilated containers or ventilated stow, and temperature monitoring on long routes
- — Avoid prolonged tropical port dwell; oxidation and histamine formation accelerate with heat
- — Insure against heat damage explicitly — standard cover may exclude inherent vice
保管の検討事項
- — Cool, dry, ventilated storage away from direct sun and heat sources
- — Restrict pile height to limit self-heating and monitor internal temperature
- — Use within 6 months of production where possible; retest freshness parameters before long storage
- — Keep retained samples and re-test TVN and peroxide value before use in sensitive diets
調達リスク
Freshness degradation in transit
対策: Define TVN and histamine limits at discharge, not at production, and appoint an independent surveyor.
Rejection at import for Salmonella or ethoxyquin
対策: Confirm the destination's residue rules before booking and place import-conformity risk on the seller.
Adulteration with non-marine protein or minerals
対策: Ash, salt, sand and microscopy checks, plus first-order testing from any new supplier.
Self-heating incident
対策: Antioxidant certification, correct declaration and monitored stowage.
Price volatility around biomass quota news
対策: Staged coverage and index-linked contracts rather than single large spot commitments.
よくある購買ミス
- — Buying on crude protein alone and ignoring TVN, histamine and FFA
- — Accepting production-date analysis for a cargo that will be tested three months later
- — Overlooking whether the plant is listed for the destination's veterinary import rules
- — Storing high-fat meal in hot warehouses and then blaming performance on formulation
- — Skipping microscopy on the first lot from a new supplier
よくある質問
What is a good TVN level?
Prime grades are typically contracted at 120 mg/100 g maximum, with premium LT meals well below that. What matters more than the number is where it is measured — a load-port TVN says little about the material you will actually use.
Do I need IFFO RS / MarinTrust certification?
Legally, usually no. Commercially, increasingly yes: aquafeed and export-oriented buyers are being asked to evidence responsible sourcing, and adding it later mid-contract is more expensive than specifying it upfront.
Is ethoxyquin still allowed?
It depends entirely on the destination market and has changed in several jurisdictions. Confirm the current rule for your import country and specify a permitted antioxidant system in the contract rather than leaving it to the producer's default.
How should I sample a fish meal shipment?
Composite sampling across the lot by an independent surveyor, split into three sealed parts — buyer, seller and umpire laboratory. Single grab samples are not defensible in a dispute.
