“…Oxygen depletion occurs under the ice when the oxygen supplies produced by water aeration and photosynthesis are limited, which potentially generates anoxic conditions with negative ecological consequences, such as winter fish kills, the loss of benthic organisms, and the activation of anaerobic processes with the accumulation of dangerous compounds (Barica and Mathias, 1979;Hargrave, 1972;Kirillin et al, 2012;Mathias and Barica, 1980;Shuter et al, 2012). Alabaster and Robertson (1961) studied the effects of diurnal changes in temperature, dissolved oxygen, and illumination on the behavior of three fish, i.e., roach, bream, and perch, which showed that the fish could select specific combinations of responses to minimize the costs of meeting their oxygen demands as DO level declined (Kramer, 1987). Buentello et al (2000) also investigated the effects of seasonal changes in DO, temperature, and their interaction on feed consumption and weight gains in juvenile channel catfish.…”
