From Fresh Fish to Powder: The Complete Production Guide
Fish powder (also called fish meal or fishmeal) is a high-protein, shelf-stable product made by cooking, pressing, drying, and grinding fish into a fine, brown powder. It is one of the most concentrated sources of animal protein available with a protein content ranging between 62% and 70% and it is rich in essential amino acids, Omega-3 fatty acids, vitamins, and minerals.
Unlike fresh fish, which spoils within hours without refrigeration, fish powder has a long shelf life, is easy to transport, and can be used across multiple industries: animal feed, aquaculture, pet food, food fortification, cosmetics, and nutraceuticals.
For smallholder processors and agro-entrepreneurs in Africa, fish powder represents a powerful opportunity to add value to a low-cost, perishable input (fresh or dried fish, fish waste, by-products) and turn it into a premium commodity that commands consistent demand year-round.
“The most efficient approach is to reduce fish to a powdered product transforming a perishable commodity into a durable, high-value ingredient.”FAO Technical Manual on Fish Meal & Oil Production

The Market Opportunity in Nigeria & Africa
If you are considering entering the fish powder business, the numbers are compelling and the window of opportunity in Nigeria specifically is wide open.
$49.9M – Nigeria’s fish powder market value in 2024
$86.7M – Projected market value by 2033 (6.3% CAGR)
3.6M – Tonnes of fish demanded annually in Nigeria
40% – Share of Africa’s fish that is currently imported
Nigeria is the fastest-growing fish powder market in the Middle East & Africa region, with demand driven by a rapidly expanding livestock and aquaculture sector, a population exceeding 200 million, and a significant protein deficit. Fish constitutes roughly 40% of Nigeria’s protein consumption, yet over 70% of fish supply is imported — representing a massive import-substitution opportunity for local processors.
Beyond Nigeria, the global fish powder market is projected to grow from USD 196 million in 2024 to over USD 310 million by 2030, with applications in animal feed, cosmetics (hair and skin care), food (sauces, baked goods, beverages), and pharmaceuticals (dietary supplements).
Fish powder products have gained particular international attention because they are relatively affordable and can directly address food security challenges especially in Africa and Asia where nutritional diversity is low. This positions well-trained local producers to serve both domestic and export markets.
Choosing Your Raw Materials
The quality of your fish powder begins with your raw material. Processors typically work with three categories of inputs:
1. Whole Industrial Fish
These are small, oily, pelagic fish caught specifically for reduction — species like sardines, mackerel, anchovies, herrings, and catfish (especially popular in Nigeria). These yield high-quality, high-protein powder and are typically the most cost-efficient source.
2. Fish Offals & By-Products
Heads, tails, bones, skin, and viscera from filleting or smoking operations. These are often free or very low-cost from fish processors and markets. Using offals is both economically smart and environmentally responsible — it solves a waste disposal problem while creating value.
3. Fish Waste from Other Processing
Remnants from cold storage, spoiled fish with no retail market, and trimmings from large-scale processing. These require careful quality assessment but can significantly reduce your raw material cost.
Key Principle:
Freshness matters, even in fish powder production. The longer fish sits before processing, the higher the fat oxidation, the lower the protein quality, and the more likely your powder will develop off-odors. Process as quickly as possible after sourcing.
The 6-Step Fish Powder Production Process
Commercial fish powder production follows a standardized sequence of operations. Each step must be controlled correctly — especially temperature and moisture — to preserve nutritional value and ensure a safe, shelf-stable final product.
1. Raw Material Preparation & Cutting
Whole fish and offals are inspected, sorted, and fed into a fish cutting machine that reduces them to uniform small pieces (ideally ≤5 cm). Uniform size ensures even cooking and pressing in subsequent steps. Removing large bones at this stage can improve final powder quality.
2. Cooking (Stewing/Heating)
Cut fish is cooked — either by direct steam injection or indirect heat at controlled temperatures. Cooking serves two critical purposes: it coagulates proteins (making them easier to press) and releases bound water and oil from the fish flesh. Cooking temperature and time must be carefully monitored; under-cooking leaves too much liquid, while over-cooking degrades protein quality.
3. Pressing (Screw Press / Expeller)
Cooked fish is fed through a press that mechanically separates it into two streams: a solid press cake (which goes on to become powder) and a liquid fraction (called press liquor, containing water, soluble proteins, and fish oil). The press liquor can be further processed to recover fish oil and concentrated fish protein valuable co-products that improve overall profitability.
4. Drying
The pressed fish cake still contains significant moisture and must be dried to approximately 10% moisture content for safe long-term storage. This is the most critical and sensitive step in the entire process. Two main methods are used: direct (flame) drying, which is fast and efficient but requires careful temperature control, and indirect (steam) drying, which is slower but gentler on nutritional value and free from fuel gas contamination. If underdried, product will mold. If overdried, proteins are denatured and nutritional value is lost.
5. Grinding & Milling
Dried fish cake is fed into a hammer mill or similar grinder to produce a uniform fine powder. Screen mesh size determines the final particle size buyers in the animal feed industry have specific size requirements. The grinding equipment must be kept clean and dry to prevent contamination and clumping.
6. Screening, Packaging & Storage
Ground powder passes through a drum screening machine to ensure uniformity of particle size. It is then weighed, bagged into moisture-proof packaging (typically polypropylene woven sacks with inner liners), labeled, and stored in a cool, dry warehouse. Proper packaging and storage are essential to preserve shelf life which can reach 12–18 months under correct conditions.
Equipment You Need
Your equipment investment will depend on your production scale. Here is a reference guide for a small-to-medium scale operation (1–10 tonnes/day):
| Equipment | Function | Scale Notes |
|---|---|---|
| Fish Cutting Machine | Reduces whole fish to small, even pieces | Essential for any scale |
| Stewing/Cooking Machine | Cooks fish to coagulate proteins and release liquids | Batch or continuous-feed options |
| Screw Press / Expeller | Separates fish cake from oil/water liquid | Capacity must match cooking output |
| Fish Meal Dryer | Reduces moisture to ~10% for safe storage | Rotary drum (direct) or steam (indirect) |
| Hammer Mill / Grinder | Grinds dried cake into fine, uniform powder | Multi-use; can grind other agro-materials |
| Drum Screening Machine | Sorts powder by particle size | Interchangeable mesh screens |
| Oil-Water Separator | Processes press liquor to recover fish oil | Optional but adds revenue stream |
| Packaging Scale & Sealer | Weighs and seals final product | Manual or semi-automatic |
Start Small, Scale Up
All-in-one integrated fish meal machines are available for small-scale producers (1–5 tonnes/day). These are a practical, lower-cost entry point before investing in separate modular equipment for higher volumes.
Quality Control & Common Mistakes
The 5 Most Common Fish Powder Production Mistakes
- Processing stale fish. Oxidized fats and degraded proteins lower nutritional value and cause off-odors that buyers will reject. Always process fresh or freshly-dried fish.
- Incorrect drying temperature. Too hot = denatured proteins, dark color, poor digestibility. Too cool or too short = moisture above 10%, leading to mold and spoilage.
- Inconsistent particle size. Buyers in feed manufacturing have strict specifications. Unscreened powder with mixed particle sizes attracts discounts or rejection.
- Poor packaging. Moisture is the enemy. Under-sealed bags or non-moisture-proof packaging causes caking, mold growth, and reduced shelf life.
- Ignoring the press liquor. The liquid fraction from pressing contains valuable fish solubles and oil. Discarding it wastes revenue and creates wastewater issues. Recover the oil and protein concentrate.
Key Quality Parameters Buyers Look For
Whether selling to feed millers, aquaculture operators, or export buyers, your product will typically be evaluated against these parameters: protein content (minimum 60–65%), moisture content (≤10%), fat content, sand and ash levels, particle size uniformity, and absence of mycotoxins or pathogenic bacteria. Investing in basic laboratory testing — or building a relationship with a testing lab — is worth it from day one.
Building a Profitable Fish Powder Business
Who Buys Fish Powder in Nigeria?
Your primary buyers will be fish feed millers and compound feed manufacturers (who use it as a protein supplement in catfish and tilapia feed), poultry and livestock feed producers, pet food manufacturers, and — for higher-grade products — food companies using it for flavor enhancers, sauces, and fortified foods. Export to neighboring West African countries is also a growing channel.
Revenue Streams
A well-run operation generates income from multiple streams: the primary fish powder/meal product, fish oil recovered from press liquor (used in cosmetics, pharmaceuticals, and as an aquaculture feed additive), and fish protein concentrate (a water-soluble product with food-grade applications). These co-products can meaningfully improve your margin per tonne of raw fish processed.
The Competitive Advantage of Local Production
Nigeria currently imports over $600 million worth of fish products annually. A significant portion of the fish meal used in Nigerian feed mills is imported from South America, Europe, and Asia — at significant cost and with supply chain volatility. Local producers who can consistently supply quality fish powder at competitive prices have a natural advantage in terms of freshness, logistics cost, and buyer relationships.

Frequently Asked Questions
Can I make fish powder at small scale without expensive equipment?
Yes. For very small-scale production (under 500 kg/day), a simplified dry reduction process using solar or fire drying followed by manual or mechanical grinding is technically feasible. This works best with non-oily fish or fish offals. However, for consistent quality and commercial viability above 1 tonne/day, investing in at least a basic integrated processing line is strongly recommended.
What types of fish are best for fish powder production in Nigeria?
African catfish (Clarias gariepinus) is the most widely available species and works well. Tilapia, bonga fish (shad), and sardines are also suitable. In practice, most processors use a mix of fish by-products and low-value whole fish from markets. The most important factor is freshness, not species.
How long does fish powder last when properly stored?
Properly dried (≤10% moisture), packed in sealed moisture-proof bags, and stored in a cool, dry warehouse, fish powder typically maintains acceptable quality for 12–18 months. Some premium products with antioxidant treatment can last longer. Exposure to moisture, heat, or direct sunlight significantly shortens shelf life.
What permits or certifications do I need to sell fish powder commercially in Nigeria?
You will typically need NAFDAC registration for food-grade products, SON certification for feed-grade products, and a business registration with the CAC. Buyers in the feed industry may also require independent laboratory certification of your protein and moisture specifications. Some export markets require NAQS (quarantine) clearance.
Is fish powder the same as fish meal?
The terms are often used interchangeably, but there is a nuance: “fish meal” typically refers to a coarser, primarily animal feed-grade product, while “fish powder” often implies a finer particle size with potential food or nutraceutical applications. In practice, the production process is identical — the difference is in grinding fineness, quality standards, and target market.
