Planning a harvest: sampling, grading and timing
How to decide when to harvest and how to get a fair price for every grade.
Know your biomass
Harvest decisions start with good sampling. Sample regularly and at several points in the pond to estimate average weight, then combine it with your survival estimate to estimate biomass.
Decide on timing
Weigh the price for a larger size against the risk and cost of growing for longer: feed, oxygen demand, disease risk and pond time. Check withdrawal periods for any treatments before you set a date.
Partial or full harvest
A partial harvest reduces biomass in a crowded pond and can let the remaining stock grow faster. A full harvest ends the crop and frees the pond for preparation.
Grade and record carefully
Record the weight and count for each grade at the pond side. Accurate grade records are the basis for fair prices, correct yield figures and a reliable FCR.
Close the loop with sales
Link each sale to the harvest it came from and record what has been paid. You then see revenue, cost and profit for the whole crop, not just the harvest weight.
How the portal helps
Harvest plans estimate biomass and value from your latest samples. Harvests are recorded by grade, sales draw from the graded harvest, and the Cycles report shows the full result of the crop.
