Feed management with finishing feeds: feed ration should be kept at the value indicated by feeding tables
In the laboratory trials performed during the project, it has been demostrated that a reduction of 30% in the daily feed ration did not yield a better growth. In the trial, two groups of fish were compared: one fed 100% of the feed ration, calculated on the bases of feeding tables for the species, water temperature and weight, and the other one fed 70% of the ration calculated in the same manner as described. After 12 weeks of feeding, the growth significantly decreased by restricting the feeding to 70% of the normal feeding ration. However, food conversion rate and protein efficiency ration were better in the case of reduced ration, indicating that this group of fish has used the feed much more efficiently. Thus, feeding tables advised by feed producers should be followed by the fish farmes with the specifications of the feed management applied to their farm.
