RESEARCH ABOUT THE INFLUENCE OF ORGANIC SELENIUM ON THE GROWTH PERFORMANCES OF THE COMMON CARP (CYPRINUS CARPIO), LAUSITZ VARIETY, JUVENILES

Abstract

The present research concerns the use of organic selenium (Se) in the nutrition of the common carp (Cyprinus carpio), variety Lausitz, during its sapling stage. The experimental work was carried out during 159 days in the Martinesti Fish Farm, near the city of Cluj-Napoca, Romania. The total number of carp juveniles was organized in two batches: the experimental batch and the witness batch. Each group consists of 200 juveniles having a mean individual weight of 1.5 g. The rearing conditions were similar for the both groups, excepting the alimentation. The experimental batch received 0.03 mg organic Se (Sel-plex) per kg of food. At the end of the experiment these juveniles reached an average weight of 354.619±0,088 g/specimen and a rate of survival of 99%, while the juveniles from the witness batch registered an average weight of 276.804±0,051 g/specimen and a rate of survival of 97%. The results reveal that the use of organic Se (Sel-plex) in the nutrition of the common carp juveniles (Cyprinus carpio), variety Lausitz, leads to an increased body mass and to a lower mortality.
