FCR Calculator

Free FCR calculator: instantly work out economic and biological FCR, feed cost per kg and the savings from a 0.1 FCR improvement, from biomass gain and feed given.

FCR Savings Calculator

Enter your current and target FCR to see your annual feed saving in tonnes and money. Calculate the big impact of a small FCR improvement.

FCR Comparison

Compare the FCR of four cages, ponds or batches side by side and see the most efficient unit and the extra feed cost of the others.

Why Is Your FCR Rising?

Find the likely cause of a rising FCR with nine short questions: feeding, water quality, stocking density, health, feed quality or measurement error.

Fish Feed Cost Calculator

Calculate your annual feed requirement, total feed cost and how much you gain when FCR improves, from production volume, FCR and feed price.

Feed Requirement Calculator

Calculate your daily, per-meal and period feed requirement and the number of bags needed, from biomass and daily feeding rate.

Feed Comparison Calculator

Compare two feeds by price and FCR; see the cost per kg of growth and the yearly difference. Cheap feed is not always economical.

Feed Price Increase Calculator

Calculate how a feed price increase affects your cost per kg of fish and your annual budget, and see which FCR you need to hold costs steady.

Feed Stock and Consumption Calculator

From current feed stock and daily consumption, calculate how many days the stock will last, when it runs out and the latest date to order.

Growth, stocking and harvest

Fish Biomass Calculator

Calculate total biomass from fish count and average weight, the remaining fish after survival, and cage/pond stocking density (kg/m³).

Stocking Density Calculator

From cage or pond volume, target density, harvest weight and survival, calculate the biomass you can carry at harvest and the number of juveniles to stock.

SGR and Growth Rate Calculator

From two sample weighings, calculate the specific growth rate (SGR), daily weight gain and how many days it takes to reach the target weight at this rate.

Harvest Date and Quantity Calculator

From current weight, target harvest weight and growth rate, calculate the estimated harvest date, harvest quantity and the feed needed until harvest.

Mortality Rate Calculator

From the starting fish count and number of dead fish, calculate mortality and survival rate, daily mortality, biomass lost and the financial loss.

Water quality

Water Quality Checker

Choose your species and enter temperature, dissolved oxygen, pH, ammonia, nitrite and salinity to see a good, caution or critical status for each parameter.

Oxygen Demand and Aeration Calculator

From biomass and oxygen consumption rate, calculate hourly and daily oxygen demand and the number of aerators needed.

Cost, profitability and processing

Fish Farm Profitability Calculator

Calculate your production cost per kg, sales revenue and gross profit from feed, fingerlings, labour, energy and other costs.

Break-Even Price Calculator

From FCR, feed price and other costs per kg, calculate the fish break-even price and the price needed for your target margin.

Fillet and Processing Yield Calculator

From live weight, calculate gutted and fillet output, by-product, and the revenue from selling gutted fish or fillets.

Free Excel Templates

Free Excel templates with ready-made formulas for feeding logs, FCR calculation, biomass, mortality, feed stock, water quality and harvest planning.
