Typical questions
How do I find the feed that performs best in my system?
Three details decide: species, fish weight and water temperature. They determine the feed line, pellet size and energy content. The feeding rate is in the table on the product sheet. Send us your farm data and we will calculate the plan for your system.
How do I change pellet size or feed without losing growth?
Where the weight classes overlap, mix the old and new pellet size for 3–5 days. A change of feed is best planned with us: the feeding plan shows which feed comes in when.
What do I do if oxygen falls or the temperature is above the optimum?
Increase the oxygen supply shortly before each feeding, by as much as the feeding will use on top. That way your fish have enough oxygen during the meal and afterwards. Read the optimum temperature for your feed from its feeding table: it is where the feeding rate is highest.
How do I check whether the feed's FCR is right?
FCR = kg feed ÷ kg weight gain, for the same period and the same tank. Record the amount actually fed (calibrate your feeders), subtract uneaten feed and include losses in the biomass. Compare the result with the achievable FCR on the product sheet: it applies under optimal conditions.
