Know-how from the mill
Frequently asked questions
From the right feed to checking your FCR properly. And everything you need to know about ordering.
Feed and feeding
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 can I tell whether my fish are really growing as they should?
Weigh a sample from each tank every 2–4 weeks. The specific growth rate SGR = (ln final weight − ln start weight) × 100 ÷ days shows the growth per day. The TGC makes periods with different temperatures comparable.
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.
Which water parameters affect growth the most?
Temperature first: fish grow fastest at the optimum for their species. Then oxygen: it falls as the water gets warmer, and feed intake falls with it. Add to that CO₂, ammonia, nitrite and a stable pH.
How does the feed affect these water parameters?
Whatever the fish does not use ends up in the water: nitrogen from protein as ammonia, phosphorus as nutrient load, leftovers as oxygen demand in the biofilter. Digestible feed with the right protein-to-energy ratio and a ration with no leftovers take the load off the system. What counts most is that no feed is left uneaten.
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 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.
Ordering and delivery
Is there a minimum quantity?
You can get our standard feeds in small quantities too. Feeds marked ● are produced to order, from 3 t per pellet size. We make your own recipes from a first order of 2–4 t, depending on the feed type.
What does the feed cost?
Prices are in the current price list, as a price per 100 kg. There are three price tiers by quantity per product: from 3 t, 0.75 t to under 3 t and under 0.75 t. The more you order, the lower the price per 100 kg. On request, we will send you the price list by email.
How does ordering work?
In five steps: enquiry and advice by phone or email, ideally with your farm data. Quotation with price per 100 kg by quantity, without obligation. Order in writing by email to info@AquafeedGermany.de. Collection ex works Beeskow within 14 days of the written order confirmation, or shipping. Invoice.
Can I collect the feed from the mill?
Yes. Prices are ex works Beeskow. Collect the goods within 14 days of the written order confirmation. We arrange shipping individually at the current rate.
How do I pay?
14 days after invoice or delivery. New customers pay for their first order in advance.
What packaging do you deliver in?
In bags of 15, 20 or 25 kg, depending on the feed. In big bags for larger quantities, and in bulk by silo for farms with silo facilities.
How long does the feed keep, and how should I store it?
At least 12 months from production, see the label. Store the feed dry, cool and out of direct sunlight. Use opened bags quickly.
Which information is binding?
The information on the bag or big bag label is binding. The catalogue and website are for guidance.
