How can I tell whether a fish farm for sale is profitable?

Test a fish farm’s reported profit against its own records: harvest and sales by customer, feed purchases and mortality logs checked against what was sold, stock on hand at year end, seasonal swings, and how much work the owner does unpaid. Where those records do not agree with each other, ask why before relying on the profit figure.

A fish farm’s profit can look steady on paper and still hide a lot. Fish take months or years to reach market size, so a year’s sales may reflect work done in earlier years, and stock still in the water may not appear as a sale. Ask an accountant how it is recorded. The practical test is to see whether the farm’s physical records and its financial statements tell the same story.

Harvest and sales records

Ask for harvest logs and sales by customer for several years. Match what was harvested to what was invoiced and what was paid. Look at who the customers are, whether any one customer carries most of the sales, and whether those customers have agreed to keep buying after a sale. Gaps between harvest and sales deserve a clear explanation.

Feed, mortality and stock on hand

Feed is usually the largest running cost, so feed purchases should line up with the fish the farm says it grew. High losses, disease events and early harvests show up in mortality logs. Ask for a count or estimate of stock at each year end, and how it was measured, since that number moves the profit up or down. A qualified accountant can show you how stock is treated in the statements.

Seasonality and the owner’s labour

Water temperature, ice, drought and market demand all change the pattern through the year, so ask for monthly cash records, not just annual totals. Then ask who actually does the work. If the owner is the feeder, the mechanic and the salesperson and takes no wage, the reported profit is partly unpaid labour you would need to replace or do yourself.

For the licence, tenure and production-system questions, read what to check before buying a fish farm alongside the records review above. BDC’s guide to financial statements is a plain starting point if you are new to reading them.
