Fish Feed Manufacturing Plant Project Report (DPR) 2026

What is fish feed?

Fish feed is a manufactured, nutritionally complete diet for farmed fish, made by grinding and blending plant proteins, grains, marine ingredients, oils, vitamins and minerals, then forming them into pellets that hold together in water. In fed aquaculture, feed is usually the largest farm cost, so a feed mill sells growth, survival and feed conversion as much as it sells tonnes.

Commercial products are grouped by species, life stage and pellet behavior. Floating extruded pellets suit tilapia, catfish and pangasius because farmers can watch fish eat and limit waste. Slow-sinking and sinking pellets serve carp, marine finfish and bottom feeders, while high-energy salmon and trout diets carry 25–35% fat and need vacuum coating.

Fish feed is classified internationally under HS code 230990, preparations of a kind used in animal feeding other than retail dog or cat food, with national schedules adding digits. Buyers are pond and cage farmers, integrated producers that own hatcheries and processing plants, and dealers that resell feed on credit across farming districts.

Fish feed market overview and global demand

Demand for fish feed follows the growth of fed aquaculture. The FAO's State of World Fisheries and Aquaculture 2026, published in June 2026, reported that aquaculture produced 103 million tonnes of aquatic animals in 2024, the first year above 100 million tonnes and 53% of all aquatic animal output.

On the feed side, the 2026 Alltech Agri-Food Outlook, released in April 2026, put world feed output at about 1.44 billion tonnes in 2025, up 2.9%. Aquaculture feed reached about 55.5 million tonnes, up 4.7%, making it the fastest-growing species segment, although it is still under 4% of all feed by volume.

Asia dominates both farming and feed milling. China is by far the largest producer, followed by Vietnam, India, Indonesia, Bangladesh and Thailand, while Ecuador's shrimp sector and Norway's and Chile's salmon sectors anchor large, high-specification feed industries in the Americas and Europe. Egypt and Nigeria lead in Africa, where much feed is still imported or made on farms. Because feed is bulky and sold close to ponds, most fish feed is consumed in the country where it is milled, and cross-border trade is a small share of output.

For context on the wider industry, Credence Research values the global compound feed market at USD 584.18 billion in 2024, growing at a 5.2% CAGR. That implies about USD 615 billion in 2025, a figure derived from the 2024 value and the CAGR rather than separately measured. Ingredient costs are tracked separately in the fishmeal supply and pricing outlook.

Fish feed manufacturing process

Most modern fish feed is extruded. Extrusion cooks the starch under heat, moisture and pressure, which binds the pellet, controls whether it floats or sinks and improves digestibility. Simpler pellet-press lines remain common for sinking carp and some shrimp feed, but they offer less control over density and water stability.

Receiving and storage. Soybean meal, corn, wheat, rice bran, fishmeal and oils arrive by truck or bulk vessel. Each lot is sampled for moisture, protein and mycotoxins, then held in silos, flat stores and heated oil tanks. Poor storage leads to mold and rancidity that no later step can fix.

Formulation and batching. Least-cost software sets each recipe against nutrient targets and the week's ingredient prices. Automatic scales dose macro ingredients, with micro-dosing for vitamins, minerals, binders and any approved additives.

Fine grinding and mixing. Fish feed needs far finer grinding than poultry feed, often to a particle size below about 250 microns, so a hammer mill or pulverizer is followed by sifting. Fine particles help the extruder form a smooth pellet and help small fish digest it. A batch mixer then produces a uniform mash.

Conditioning and extrusion. Steam and water raise moisture and temperature in a preconditioner before the mash enters a single- or twin-screw extruder. Die design, screw speed and moisture set pellet size and expansion, which decides whether the pellet floats, sinks slowly or sinks fast.

Drying and coating. A belt dryer brings moisture down to about 8–10% for safe storage. A vacuum coater then pushes oil into the pellet, which matters most for high-fat salmon and trout diets.

Cooling, screening and bagging. Pellets are cooled, screened to remove fines, which are recycled, then packed in 20–25 kg bags or loaded in bulk. Retained samples from each batch support complaints and traceability.

Fish feed plant setup cost

This overview models a greenfield mill producing 50,000 tonnes of extruded fish feed a year, about 167 tonnes a day over 300 days, using two extrusion lines of roughly 4–5 tonnes an hour each. Estimated total CapEx is USD 9–20 million at an Asian industrial site, excluding working capital.

The range comes from disclosed mills, scaled with a 0.65 capacity exponent. Skretting's Surat plant in India, opened in February 2023 at EUR 18.5 million for 50,000 tonnes a year on three lines, is about USD 20 million at the same capacity and sets the top of the range. Haid Group's 150,000-tonne Malaysian project, announced in August 2026 at RM 140 million, scales to about USD 16 million. Cargill's 90,000-tonne mill in Vijayawada, India, built in 2018 for more than USD 10 million, scales to about USD 9 million after cost escalation and sets the floor. The spread mostly reflects line count, automation and how much ingredient storage is built.

Worked example, land and site development. Skretting's 50,000-tonne mill occupies 20,000 square meters, so an assumed 2–3 hectares allows for silos, truck queues and later expansion. At an assumed USD 20–60 per square meter in an Asian industrial park, land costs USD 0.4–1.8 million. Site works add an assumed USD 0.3–0.6 million, so the row is about 8–12% of CapEx. An assumed USD 40–120 per square meter at a U.S. or EU site would mean USD 0.8–3.6 million for land alone, and higher construction and labor costs would likely put such a mill at or above the top of the range. The full report can be customized to any country.

Working capital is heavy because many fish farmers buy feed on 30–90 day credit. Inventory and receivables could tie up an estimated USD 3.5–7.5 million.

Ingredients take about 84–89% of operating cost.
