Excel or Fish Farm Software?
The pros and limits of running a fish farm on Excel; when to switch to software, how to migrate and what gets automated.
Excel is a good starting tool. But as cages, staff and data grow, scattered files lead to errors, lost time and problems noticed too late.
Excel’s strengths
- Free and familiar
- Quick start and flexible sheets
- Can be enough for small farms
Excel’s limits
- Real-time entry from the field is hard, so records lag.
- Several people editing the same file creates version chaos.
- Formula errors affect decisions unnoticed.
- There are no alerts when thresholds are crossed.
- Feed stock, biomass and FCR are not linked automatically.
When should you switch to software?
- If you manage several cages, ponds or sites
- If several people enter records in the field
- If you want to see FCR and costs weekly
- If buyers ask for traceability records
How to make the switch
Stock, cage and feed data from your current Excel sheets is imported, and the team starts entering records by phone in the field. Every calculation you did by hand is then done automatically.
A realistic look at the cost of Excel
Excel itself is cheap, but the work around it is not. On a typical multi-cage farm, someone collects paper forms from the field, types them into spreadsheets, checks formulas, merges files from different sites and prepares reports for management. That can take several hours every week. Errors are found late, often at the end of the month, when the decisions they affected have already been made. The real cost of a spreadsheet system is staff time plus the cost of decisions taken on delayed or wrong data.
Typical spreadsheet failures
- A formula range that does not include newly added rows, so totals silently miss data.
- Two people saving different versions of the same file.
- Mortality entered in one file and not in the biomass sheet, so feeding is calculated on too many fish.
- Feed stock that does not match the feed recorded as given, with no way to see where the difference arose.
- Historical data that is overwritten or lost when a file is restructured.
None of these is a reason to blame the people using Excel. They are structural limits of using separate files for connected operational data.
What farm management software adds
| Need | Excel | Farm management software |
|---|---|---|
| Field data entry | Paper, then typed later | Phone or tablet at the cage, same day |
| Biomass and FCR | Manual formulas per file | Calculated automatically from all records |
| Feed stock | Separate sheet | Reduced automatically by each feeding |
| Alerts | None | Thresholds for mortality, oxygen, stock levels |
| Multiple users | Version conflicts | Roles and permissions, one dataset |
| Traceability | Links between files break | Lots linked from stocking to sale |
| Audit trail | Changes not recorded | Who changed what, and when |
Making the transition work
- Clean the current data. Agree on the cage list, current fish numbers, average weights and feed stock before importing.
- Start with daily essentials. Feeding, mortality and water quality entry in the field bring the quickest benefits.
- Run in parallel briefly. Keep the spreadsheet for a few weeks to compare results, then stop, so that staff do not maintain two systems.
- Train by role. Field staff need simple entry screens; managers need reports and dashboards.
- Review the first month. Check data completeness and adjust forms and alerts.
When Excel is still enough
A small farm with one site, a few units and a single person keeping records may manage well with spreadsheets, especially if it does not sell to buyers that require traceability. Even then, consistent templates and a weekly routine make the data more useful and make a later switch easier.
Frequently asked questions
Can existing Excel data be imported?
Yes. Cage lists, stock, feeding history and customer data can usually be imported, so the new system starts with your history rather than an empty database.
Do we need an internet connection at the cages?
Not always. Many mobile apps record data offline and synchronise when a connection is available.
How long does the switch take?
For a single site with clean data, field teams can usually start entering daily records within days. Multi-site groups with finance, sales and traceability needs take longer, because each module is introduced and checked in turn.
What happens to our Excel templates?
The calculations they contain, such as biomass, FCR, feed requirement and cost per kilogram, are performed by the software from the records. Many farms keep using free Excel templates for quick what-if calculations outside the operational system.
Who should own the data?
The farm. Make sure data can be exported in common formats at any time.
