Turning trimmings, frames and viscera into meal, oil, hydrolysate and silage.
Request matched quotesShort answer
How much does a by-product & fishmeal systems cost?
- Meal yield:
- 18–23% of raw by-product weight
- Oil yield:
- 3–8% depending on species and season
- Revenue contribution:
- Typically 3–8% of plant turnover
- Drying energy:
- Largest single OPEX item — compare kWh or steam per tonne evaporated
Throughput and indicative CAPEX bands
Indicative equipment supply only (EXW/FOB). Building, civil works, duties and local installation are additional.
| Scale | Throughput | Indicative CAPEX | Typical scope |
|---|---|---|---|
| Silage | 2–20 t/day | USD 40k–150k | Grinding, acid dosing, storage tanks — lowest-capital entry route. |
| Hydrolysate | 5–20 t/day | USD 120k–500k | Enzymatic reactors, separation, evaporation and drying. |
| Fishmeal & oil | 20–150 t/day | USD 1M–5M | Cooker, press, decanter, separator, dryer, odour treatment. |
| Integrated | 150 t/day+ | USD 5M–15M+ | Full meal/oil plant with heat recovery and emissions control. |
What a complete scope must cover
Collection & chilling
Fresh, chilled raw material — freshness determines meal and oil quality more than any machine.
Conversion
Cooking and pressing, enzymatic hydrolysis or acid preservation depending on target product.
Separation & drying
Decanters, separators, evaporators and dryers; drying is the main energy cost.
Odour & emissions
Scrubbers and biofilters, frequently a permit condition near populated areas.
Storage & dispatch
Bagging or bulk silos, oil tanks, quality lab and certification.
Machine, line, turnkey plant or EPC scope?
Compare offers at the same responsibility level. A low machine price is not comparable with a line that includes controls, utilities, installation and performance acceptance.
| Scope | Typically includes | Buyer retains | Use when |
|---|---|---|---|
| Single machine | One defined operation and controls | Interfaces, utilities, installation and line balance | The factory and upstream/downstream process already exist |
| Complete line | Connected process equipment, controls and throughput duty | Building, major utilities, cold store and permits unless stated | One product flow needs a measurable output guarantee |
| Turnkey plant | Line, utilities, installation, commissioning and training as contracted | Land, approvals, raw material and items expressly excluded | The buyer wants fewer package interfaces |
| EPC scope | Engineering, procurement and construction coordination under an agreed contract | Owner decisions, financing, permits and operational inputs | Civil works and multiple technical packages must be integrated |
Selection criteria
- •Raw material freshness logistics before machine selection
- •Target product: feed-grade meal, pet food, hydrolysate or fertiliser
- •Odour control acceptable to the permitting authority and neighbours
- •Drying energy per tonne of water evaporated
Costly mistakes
- •Treating by-product as waste and paying disposal instead of building a revenue line
- •Under-estimating odour permitting near towns
- •Sizing a meal plant on peak season only, leaving it idle most of the year
Put this in your RFQ
- •State raw material tonnes, species, freshness and target product spec
- •Ask for meal and oil yield guarantees with a documented test
- •Include odour control and emissions compliance in the same tender

Equipment scope
What equipment does a commercial aquaculture project actually need?
A grow-out project typically needs holding infrastructure (tanks, ponds or cages), water movement (pumps, piping, valves), aeration or oxygenation, water treatment appropriate to the system, feeding equipment, grading and handling gear, monitoring and alarms, and backup power. RAS adds mechanical filtration, biofiltration, degassing, disinfection and tighter process control. Hatchery and processing scopes are specified separately.
Which equipment should be specified before requesting quotes?
Specify the items whose sizing changes everything downstream: design biomass and stocking density, water exchange or recirculation rate, oxygen demand at peak temperature, and installed pumping head. With those four fixed, suppliers can quote aeration, filtration, pumps and power on the same basis. FishMatch calculators produce these figures and attach them to the RFQ.
Can equipment be sourced in stages?
Yes, and phased procurement is common. The usual sequence is water supply and holding infrastructure, then aeration and treatment, then automation and monitoring, then processing and cold chain. Staging works when interfaces and capacity headroom are defined at the start; otherwise later phases force replacement rather than addition.
