I.M. Dzyubuk, L.P. Ryzhkov. Growth and survival of rainbow trout fingerlings in a fish farm in Karelia // Transactions of Karelian Research Centre of Russian Academy of Science. No 5. Experimental biology. 2014. Pp. 117-122
Keywords: cage fish breeding, trout, fingerlings, stocking material, growth, survival, Lake Onega.
The results of rearing rainbow trout figerlings obtained from local bloodstock from a cage farm in Kondopozhskaya Bay of Lake Onega are presented. The feassibility of growing fingerlings both in pools and in cages at high survival rates (up to 96 %) is demosrated. Cycles in larval growth rates, caused by environmental conditions and ontogenetic patterns, were found. The borders of favorable growing conditions for the whitebaits are recommended. The upper limit of favorable temperature for the fingerlings is 19.5 ºC (optimum at 14–16 ºC), the lower limit of oxygen concentration in water is 6.5 mg/l, favorable pH is 6.8–7.8.
