- How harvest is planned from growth data
- Where farm management ends and fish health science begins
What this project is
Fish farming is animal husbandry in water. Stock is held in ponds, cages or tanks, fed daily, monitored for growth and health, and harvested when it reaches market size. A farm management platform tracks each production unit: what stock it holds, of what species and age, how much it has been fed, how it is growing, and how many have died. That record drives the daily decisions: how much to feed, when to grade, when to treat, and when to harvest.
Feed is the largest cost and the largest lever. Overfeeding wastes money and pollutes water; underfeeding slows growth. The platform should record feeding against growth, so the feed conversion ratio, feed given against weight gained, can be tracked by pond or cage. A unit with poor conversion needs attention: it may be overfed, diseased, or stocked too densely. Without feed and growth records together, that judgement is guesswork.
Core features
- Production unit management for ponds, cages and tanks, with stock, species and age per unit
- Stocking, grading, transfer and harvest records, keeping stock numbers honest
- Feeding records by unit and day, with feed type and quantity
- Growth sampling and feed conversion tracking by unit
- Mortality recording with causes where known, and mortality rate alerts
- Harvest planning from growth data and market size targets
How it is built
- Map the farm first: ponds, cages or tanks, species, and the production cycle for each
- Build stock and feeding records, then growth and mortality tracking
- Add harvest planning, then reporting by unit, species and cycle
- Test feeding and growth entry with farm staff on a real production cycle
- Pilot on one farm section for a full cycle, comparing tracked growth with actual harvest
Technology considerations
Data entry must fit farm work. Staff feed and check stock in wet, outdoor conditions, often with gloves, so mobile entry with simple forms and offline capability matters more than a detailed desktop system. Stock numbers are the hardest data to keep honest: mortality, grading, transfers and harvests all change the count, and a missed entry corrupts every later calculation. The system should reconcile stock numbers regularly, flagging units where the recorded count no longer matches sampling or harvest data.
Water quality data, where available from sensors or manual tests, should link to production units, because growth and mortality often follow water conditions. But the platform should not require sensor integration to be useful: manual water quality entry, done consistently, is enough to spot patterns. Growth sampling needs a consistent method too: samples taken differently each time produce growth figures that cannot be compared.
For the first version, manage one farm section for a full cycle: stock numbers, feeding, growth sampling and mortality, with feed conversion tracked by unit. Farm managers judge the platform on whether stock numbers stay honest through grading, transfers and harvest. A platform that does that for one section, with feeding and growth recorded together, proves the discipline needed to run the whole farm on it.
Challenges to plan for
- Stock numbers that drift because mortality or transfers were not recorded
- Feed records that do not match growth, because feeding was estimated rather than recorded
- Growth samples taken inconsistently, making growth rates incomparable
- Harvests planned from old growth data, missing the market size window
Who it is for, and its limits
This suits a fish farm operator, an aquaculture company or a cooperative managing several farms. It fits farms where stock, feed and growth drive profitability. It does not fit a small backyard pond, and it is not a fish health diagnostic system: it tracks health indicators, diagnosis stays with veterinarians and specialists.
A farm platform does not grow fish. Growth depends on stock, feed, water and health; the platform makes those factors visible and the decisions based on evidence. Costs vary with farm size and production units, so confirm with a quote after the farm is mapped.
Frequently asked questions
What is feed conversion ratio?
Feed given divided by weight gained, for a pond, cage or cycle. A lower ratio means more efficient growth. Tracking it by unit shows which units are performing and which need attention.
How is growth tracked?
By sampling: weighing a sample of fish at intervals and estimating average weight and growth rate for the unit. Consistent sampling methods make growth rates comparable over time.
What is grading?
Sorting stock by size within a unit, or moving stock between units to keep sizes uniform. Grading reduces competition and cannibalism, and is recorded so stock numbers stay accurate.
How is mortality handled?
Daily mortality is recorded by unit, with causes where known. Rising mortality rates trigger alerts, because they may signal disease, water problems or other issues needing action.
When is stock ready to harvest?
When growth data shows it has reached market size, and when the farm's harvest plan and market demand align. The platform forecasts readiness from growth trends, but the harvest decision stays with the manager.
