Abstract	The effects of water temperature (5, 8, 11, and 14°C) on the fractional rate (percent per day) of protein consumption (k_r) and on white muscle and whole-body fractional rates of protein synthesis (k_s), protein growth (k_g), and growth efficiency (PPV, growth/consumption; k_g/k_s, growth/synthesis) of juvenile Atlantic wolffish (Anarhichas lupus) (initial body weight 26 g) were studied. Rates of protein consumption and white muscle and whole-body protein synthesis increased in a linear fashion between 5 and 14°C. In contrast, the relationships between temperature and white muscle and whole-body protein growth, protein growth efficiency (PPV) and protein synthesis retention efficiency (k_g/k_s) were parabolic. The results indicated that the optimum water temperatures for growth (T_opt.G) and growth efficiency (T_opt.GE) were 10-11 and 9-10°C, respectively. The maximum white muscle and whole-body protein growth rates recorded at T_opt.G were 0.9 and 0.7 %·day^-1, respectively. At T_opt.GE, the maximum white muscle and whole-body PPV values were 28 and 34%, respectively, and k_g/k_s values were 92 and 51%, respectively. The growth performance data for juvenile Atlantic wolffish in comparison with published data for salmonids (rainbow trout (Oncorhynchus mykiss), Atlantic salmon (Salmo salar)) at 9-11°C further highlight its suitability as an alternative species for cold-water aquaculture in northern Europe and Atlantic Canada.
