Worked example from the catalogue, without losses, at constant temperature. In practice it takes longer and needs more feed. FCR values under optimal conditions, according to the product sheet.

Target: 80 kg, first caviar after about 10 years (given, not calculated). From 2 kg, broodstock feed FSL 47/15 EX 80 AX. FCR according to the product sheets, pp. 26 and 28.

Above 16 °C, the mill recommends FSM 48/20 EX from 35 g (p. 27); the worked example at 16 °C uses FSM 47/15 EX.

Water parameters

Guide values from the technical literature and mill data. They do not replace measurements in your system, but they show you where to look.

Optimum
17⁠–⁠20 °C
Oxygen
≥ 5⁠–⁠6 (outlet) mg/l
pH range
6.5⁠–⁠7.5
Stocking density
15⁠–⁠25 kg/m³
Temperature in the worked example

Sources: TransFarm/Interreg Central Baltic (2023) for trout, sturgeon, carp, African catfish, tilapia, pikeperch; NRC (1993)/NCRAC (2003) for tilapia oxygen; Crustaceans in general (TransFarm); outlet values for trout and sturgeon and the trout optimum: mill data.

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.

Read more: Find feed

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.

Read more: Request a feeding plan

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.

Read more: Feeding by temperature and oxygen

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.
