Researches considering the effect of the gradual insertion of fodder in alimentation for the growth rhythm of Siberian sturgeon larvae (Acipenser baerii – Brandt, 1869) reared in superintensive system
The experiment was made inside of private sturgeon rearing farm S.C. “Beluga Farm Group” S.R.L. from Calarasi County. The rearing system is flow-through and is emplaced into an enclosure as halltype. Sturgeon larvae were reared in spun glass troughs of a 0.167 m3 capacity. Experiment duration was 20...
