Aquaculture questions people search for — answered
The questions below come from real Google searches that led people to FishMatch Group. Each has a short answer and a link to the page or calculator that covers it in depth.
Calculators and formulas
How does a shrimp survival calculator work?
It multiplies the number of post-larvae stocked by the expected survival rate and the target harvest weight to estimate harvest biomass. Our calculator also adds feed (FCR), pond area and cycles per year so you can compare scenarios and export a PDF.
Open the full guide →How do you calculate pond volume in litres or gallons?
Multiply length × width × average depth to get cubic metres; one cubic metre is 1,000 litres (about 264 US gallons). For sloped ponds, use the average of the shallow and deep ends as the depth.
Open the full guide →How is fish biomass calculated?
Biomass is the number of fish multiplied by their average weight. Sample-weigh a group of fish, take the average, and multiply by the estimated head count after mortality.
Open the full guide →How do you calculate FCR (feed conversion ratio)?
FCR is the feed given divided by the weight gained. For example, 1,500 kg of feed that produced 1,000 kg of growth is an FCR of 1.5. Lower is better.
Open the full guide →What does stocking density mean and how do I calculate it?
Stocking density is how much fish or shrimp you hold per unit of water or area — usually kg per cubic metre or animals per square metre. Divide the planned biomass or count by the tank volume or pond area.
Open the full guide →How much aeration or dissolved oxygen does a pond need?
It depends on biomass, feeding rate and water temperature: more feed means more oxygen demand. Size aerators to peak biomass with a safety margin and plan backup for power cuts.
Open the full guide →How do I calculate the return on better aquaculture feed?
Compare the cost per kilogram of fish produced, not the price per bag: feed price × FCR. A more expensive feed with a better FCR can lower the cost of production.

How much does a RAS (recirculating aquaculture system) cost?
RAS cost depends mainly on annual tonnage, species, building and level of redundancy. Use our RAS cost calculator for a first budget range, then compare supplier quotations on the same design basis.
Open the full guide →How much does it cost to start a shrimp farm?
The budget depends on pond or indoor system type, area, intensity, water supply and local construction costs. Our shrimp farm cost guide breaks down the main items so you can plan before asking for quotes.
Open the full guide →How do you start a shrimp processing plant, and what does it cost?
Start with raw-material volume, product form (head-on, peeled, cooked, IQF) and export market rules. These decide the line, cold storage and building — and therefore the cost. Our project page explains the scope.
Open the full guide →What does a fish processing plant cost?
Cost depends on daily capacity, product (fillets, frozen, smoked, sticks), freezing method and hygiene standard. Define capacity and products first, then compare line quotations.
Open the full guide →How much does it cost to build a commercial fish farm?
Capital cost scales with production system (ponds, cages, RAS), tonnage and site works. Our CAPEX guide shows how to build a budget and which items are most often missed.
Open the full guide →RAS or biofloc — which is better?
RAS gives more control and water reuse but costs more and needs skilled operators; biofloc is cheaper to build but harder to keep stable at scale. Our comparison covers cost, energy, species fit and risk.

What does grow-out mean in aquaculture?
Grow-out is the stage where juveniles are raised to market size, after the hatchery and nursery stages. It is usually the longest and largest part of a farm.
Open the full guide →What is the difference between the nursery phase and grow-out in shrimp farming?
The nursery phase raises post-larvae to stronger juveniles in a small, controlled area; grow-out then takes them to harvest size in larger ponds or tanks. A nursery step usually improves survival.
Open the full guide →Is sea bream (and sea bass) farmed?
Yes. Gilthead sea bream and European sea bass are widely farmed, mainly in sea cages in the Mediterranean, with hatcheries supplying the juveniles.
Open the full guide →Is shrimp farming possible in Ghana and Kenya?
Yes — both have warm water and coastal sites, but projects need a reliable post-larvae and feed supply and proper permits. Our country pages cover conditions and planning steps.

Where can I buy aquaculture equipment and machinery?
For a single part, go to a dealer. For a farm or several linked systems, send one RFQ so qualified manufacturers quote on the same scope. FishMatch Group prepares that RFQ and returns comparable proposals.
Open the full guide →Which aquaculture equipment suppliers are the best?
There is no single best supplier; the right one has proven references for your species, scale and climate. Compare 3–5 quotations on the same design basis, with commissioning, spares and warranty included.
