Shrimp Farm Cost per kg: Survival, FCR and Margin Sensitivity

Short answer: the production cost of a kilogram of farmed shrimp is built from a small number of drivers — post-larvae (PL) price and survival, feed price and feed conversion ratio (FCR), energy for aeration and pumping, labour, pond preparation and health inputs, and harvest logistics. Survival and FCR multiply almost every other line, so they usually move the margin more than any single equipment choice. This guide sets out the framework, a worked planning example and a sensitivity table. All figures below are illustrative planning assumptions, not market prices or expected results; replace them with your own site data.

1. Why shrimp economics are worked per kilogram

Investors and lenders compare shrimp projects on cost per kilogram harvested, because it combines biology and operations into one number that can be set against the farm-gate price the market offers. The whiteleg shrimp (Penaeus vannamei) dominates farmed shrimp supply, and FAO's cultured species profile describes how widely production systems differ — from extensive ponds to intensive lined ponds and indoor systems. That variety is the reason a cost per kilogram from one farm, one country or one season cannot simply be copied into another business plan.

2. The cost stack, line by line

A practical cost stack for one crop has six lines. Post-larvae cost is the number stocked multiplied by the price per thousand. Feed cost is harvested biomass multiplied by FCR and the delivered feed price. Energy is the kilowatt-hours used by aerators, pumps and blowers multiplied by the local tariff. Labour is the share of salaries carried by that crop. Pond preparation, water treatment and health inputs are usually budgeted as a lump sum per crop. Harvest and first logistics — ice, chilling, transport to the processor — are usually priced per kilogram.

• Post-larvae: number stocked × price per 1,000
• Feed: harvested kg × FCR × delivered feed price
• Energy: kWh for aeration and pumping × site tariff
• Labour: crop share of salaries and supervision
• Pond preparation, water treatment, health inputs
• Harvest, chilling and transport to the buyer

Each line is easy to estimate on its own. The difficulty is that survival and FCR sit inside several lines at once, so an error in either propagates through the whole stack.

3. A worked planning example

The example below is a single 1-hectare intensive pond, stocked at 60 PL per square metre and harvested at 20 grams. The assumptions are chosen to make the arithmetic visible, not to represent any market. With 75 % survival the crop yields 450,000 shrimp, or 9,000 kg.

In this example feed is close to half of the crop cost, which is consistent with how researchers describe fed aquaculture in general: economic models of land-based recirculating salmon farms, for instance, put feed at about 49 % of production cost (Freshwater Institute/SINTEF). Your own share will depend on feed price, FCR, energy tariffs and wages. You can rebuild this table with your own inputs in the shrimp cost per kg calculator.

4. Survival is the multiplier

Survival decides how many kilograms carry the costs that are already sunk into the crop. Post-larvae, pond preparation, most of the energy and all of the labour are spent whether 65 % or 85 % of the animals reach harvest. Feed eaten by shrimp that later die is also lost. The World Organisation for Animal Health notes that biosecurity at farm level can bring improved survival, growth and feed conversion (WOAH Aquatic Animal Health Code, chapter 4.1) — which is why prevention spending belongs in the economics, not in overhead. The shrimp survival profit calculator shows how quickly revenue and cost per kilogram change with survival for your own stocking plan.

5. Sensitivity: survival versus FCR

The table below re-runs the worked example with one driver changed at a time. To keep the comparison readable, FCR is held constant when survival changes; on a real farm a mortality event usually worsens economic FCR as well, so the true spread is wider.

Two points stand out. First, neither driver is minor: ten points of survival or 0.2 of FCR each move cost per kilogram by roughly a quarter of a dollar in this example. Second, survival changes the volume you sell as well as the cost of each kilogram, so its effect on total margin is larger than the cost-per-kg column alone suggests. Test your own ranges with the shrimp farm calculator and the harvest profit calculator.

6. Feed, FCR and feeding control

Economic FCR — total feed delivered divided by biomass actually harvested — captures feed lost to waste, uneaten pellets and mortality. Feed quality, ration control, water quality and stock health all show up in it. Because feed is the largest line, a buyer evaluating feeders, feed storage or monitoring equipment should translate the claimed improvement into kilograms of feed per crop and test it in the FCR cost impact calculator and the shrimp feed requirement calculator. Our separate guide on how to calculate and interpret FCR explains the measurement boundaries.

7. Energy, water and labour

In intensive ponds, aeration is normally the main electrical load and the main protection against low dissolved oxygen at night. Compare aerators on oxygen transferred per kilowatt-hour under comparable test conditions, reliability and local service — not purchase price alone — and price the energy against your actual tariff in the shrimp farm energy calculator. Water intake, treatment and discharge carry pumping energy and, in many regions, permit conditions; the water consumption calculator helps size that side. Labour scales with intensity: a trained technician who keeps feeding and water-quality records often matters more than additional general labour.

8. Harvest size, price and logistics

Shrimp are usually sold by size count, so the commercial question is how many kilograms at which count. Holding a crop longer adds size but also feed, risk days and a later next crop. Realised price also depends on what arrives at the buyer: chilling at harvest, transport time and documentation. Planning the cold chain together with production protects the price the market offers; the cold storage calculator sizes that capacity. Use the break-even price calculator to see the minimum price at which your cost stack works.

9. Which levers usually pay back first

Across most farm types, the order of impact per unit of management effort tends to be: survival, because it multiplies everything; FCR, because feed is the largest line; growth and cycles per year, because fixed costs spread over more kilograms; harvest size strategy; and only then substitution of equipment. That order is a planning heuristic, not a rule — a farm with a severe energy tariff or a weak cold chain may find its biggest lever elsewhere. Upgrades should be judged on added yield or survival against added operating cost and capital, as in the shrimp farm upgrade calculator.

10. Limits of this framework

The example is a single-pond, single-crop model. It does not include capital recovery, financing cost, land, taxes, certification, effluent treatment or currency risk, and it assumes a constant FCR within each scenario. Survival and growth depend on species, PL source, climate, water quality and management, and should be estimated with qualified local aquaculture and animal-health professionals. Treat the outputs as planning estimates for comparing options, not as forecasts of profit.

11. From the numbers to a procurement brief

When the economics point at a specific weakness — aeration capacity, feed delivery, water treatment, nursery capacity or cold chain — the fix becomes a specification that suppliers can quote against. FishMatch Group is a buyer-side, supplier-neutral sourcing service: the planning tools are free, and managed sourcing generally starts with projects of about USD 250,000. Every brief is reviewed by a person with the project owner before any supplier is approached; buyer details are never forwarded automatically. Start with the human-reviewed project intake, or test your numbers first in the shrimp cost per kg calculator.
