Szlauer L., Piesik Z., 1976. An attempt to rear rainbow trout (Salmo gairdneri Rich., 1863) in a temperature controlled tank. Acta Ichthyol. Piscat. 6 (2): 125-135.
Rainbow trout were kept for 1 year in a tank of 2.5 m3 capacity, protected from overheating in summer and heated in winter. No water change was applied during the culture period. The fishes cultured showed good weight increments: the average weight of an 18-month old specimen was 193.3 g.
