How to Compare Aquaculture Feed Suppliers: Specification, Quality, Traceability and On-Farm Trials

Short answer: compare aquaculture feed suppliers on the same written specification and on evidence from your own farm, not on brochures. Ask each supplier for the product's declared analysis and pellet specification for your species and stage, batch-level quality and traceability documents, storage and shelf-life conditions, a feeding table, and the landed price. Then run a fair on-farm trial — same system, same stocking, same sampling and the same FCR definition — and decide on cost per kilogram of saleable harvest.

What should a feed supplier put in writing?

How do you check quality and traceability?

Feed composition varies by ingredients and batches, so analysis must be specific and current to be useful (FAO feed variability). Keep a retained sample from every delivery, file the lot number with the units fed, and record storage conditions. Where buyers or markets require responsible feed, check the scope of certifications such as the ASC Feed Standard or BAP feed mill standards directly with the certifier, rather than relying on a logo. Import rules and feed registration are set by national authorities; confirm what applies in your country.

How do you run a fair on-farm feed trial?

• Write the question first: for example, cost per kg of gain and saleable harvest for diet A vs diet B in grow-out ponds or cages of one species.
• Use comparable units: same system, stocking batch, density, water source and management; several units per diet where the farm allows it.
• Fix the method: same sampling, biomass estimate, feeding table logic and mortality counting for both diets.
• Define FCR before you start — biological or economic — and keep it for both diets (FCR guide).
• Record feed given per unit per day, batch numbers, water quality and oxygen, mortalities and harvest weight and size grade.
• Stop and call an aquatic animal-health professional if mortality or disease signs appear; do not interpret a health event as a feed result.

FAO's on-farm feeding review explains why rations must follow measured demand (FAO on-farm feeding); a trial that overfeeds one diet compares feeding practice, not feed.

How should the results be compared?

Calculate, for each diet: feed cost per kg gain = FCR × landed price per kg; survival and saleable kilograms; size distribution and price received; and any change in oxygen use or water-quality management. A cheaper feed with a higher measured FCR or lower saleable harvest can cost more per kilogram sold. Model scenarios with the FCR calculator, feed cost optimizer, fish growth calculator or shrimp cost per kg calculator. These tools model the numbers you enter; they do not replace the trial.

Questions buyers ask

Where does FishMatch fit?

If the trial points to a system limit — feeders, storage, aeration or oxygen at the planned ration — define the outcome and submit a project request. Managed procurement is for commercial B2B projects from USD 250,000. The FishMatch team reviews your brief, contacts suitable providers for you and presents comparable responses through FishMatch; buyers and providers are not handed each other's contact details. Bulk feed purchasing itself is handled by our sister service FeedMatch Group; no project data is transferred automatically.
