STUDY ABOUT SUPPEMENTARY FEEDING OF CARP WITH GRANULATED MIXED FEEDS

Doina Leonte, C. Leonte

Abstract
For achieving of high fish production on hectare is necessary, unless natural feed, to use supplementary feed sources.
Usually, in classical farms there are administered supplements consist in cereal meal and its subproducts and groats.
A modern reasonable feed implicates using of granulated feeds that correlate nutrient viewpoint with species-age-category requirements of grown fish and it lends oneself, for administering, to aquatic medium.
Our investigation were effectuated on two lots of one summer old Cyprinus carpio sapling, during 45 days period (26 of July-10 of September).
The analysed data served for prominence of weight growing, feed input and survival of fish from both lots (voucher lot –LM and experimental lot-LE), wich was feeded with granulated feed with 28%(LM) and 38%(LE) protean value.
In the end of experiment, on experimental lot were obtained, comparative to voucher lot, a 22.8% biger corporal weight, a/shorter input index and a 17 percent points beter viability, results wich mark out the advantages of using in carp feeding of granulated feeds with high protean value.
