Feeding fish often estimate the so-called feed ratio showing the amount of feed (in kg), should eat fish to give 1 kg of gain.
For example, if they say that feed efficiency of sunflower meal is $ 4, this means that in order for the fish increased weight by 1 kg, she had to eat 4 kg of this cake.
In other words, feed coefficient expresses the ratio of eaten to increase.
Sometimes to determine the effectiveness of feeding favour by not feeding ratio, and the so-called forage payment, or, in other words, the feed consumption per unit growth of fish.
This indicator expresses the ratio between the amount specified (and not eaten, as in determining the feed ratio) in the feed pond to increase fish.
The latest from economic point of view is more correct .
Payment of feed cannot be identified with the ratio of forage, as is sometimes done .
Indicators feed ratio will always be lower than the payment of food, not all food as defined in a pond, eaten by fish, some feed (due to various reasons) always lost.
Total feed ratio and payment of the feed, the lower their performance, the greater the effect of feeding, i.e. feed between the index (and the payment of feed) feed efficiency observed inverse relationship. Continue reading
