Growth, survival, condition (Fulton's coefficient) and biological quality (salinity stress test) were compared in 2-month-old burbot (20 mg BW, 10.9 mm TL) reared at 12,15,18, and 21°C. At 15°C, the fish showed the best growth in BW and TL (170 mg and 24.5 mm, respectively), and the highest final survival rate (97%), whereas their condition coefficient and tolerance to salinity proved to be the second best. This may indicate that a temperature of 15°C should be used for the practical purposes of juvenile burbot mass production under controlled conditions.
