RESEARCHES REGARDING THE GROWTH OF HYPOPTHALMICHTHYS MOLITRIX AND CTENOPHARYNGODON IDELLA JUVENILES IN AN INTENSIVE SYSTEM

Abstract

The intensive net cage system is based on the superior capitalization of the accumulation lakes or other different basins through the use of different types and dimensions, stationary or floating net cages, depending on categories like age, species and destination. This study is about the use of net cage intensive system type in the growth of juveniles Ctenopharyngodon idella and Hypopthalmichthys molitrix species. From the experimental point of view, the objectives were represented by the construction of a net cage mini-system and the surveillance of the biological material inside this system. The experiment was unfolded on the length of 38 days at the Mǎrtineşti Fish Farm from Cluj County. A net cage system designed and conceived by the research collective was populated with 4000 juveniles fish from each species. At the beginning of this experiment the juveniles fish had a medium weight of 2 grams/sample. At the end of this experiment the fish had a medium weight of 9 grams.
