Lota lota Larvae Temperature during larval development Five constant temperatures of 12, 15, 18, 21 and 24°C (range ± 0.5°C), all in duplicate, were employed in the experiment. The fastest larval growth, either in terms of total length or body weight, was recorded for the temperature of 21°C, whereas at 12°C the larvae grew the slowest. A final survival rate of at least 90% was observed for the burbot reared at 12 and 15°C; this figure was significantly higher than at the other water temperatures. The fish reared at 12°C had the second highest survival rate at 72%. 12.0 °C
Lota lota Larvae Temperature during larval development As evidenced by these results, a temperature of 21°C would be closest to the optimum growth temperature (OGT) for larvae of this species. The results presented here also indicate that a temperature of 18°C or lower and particularly 24°C are out of the optimal range for larval burbot because of either relatively slow fish growth or unsatisfactory survival or both 21.0 °C
Lota lota Larvae Sibling intracohort cannibalism No cannibalism occurred at any temperature throughout the experiment, although in this species it may appear at about 12 mm TL Absent
Lota lota Larvae Onset of exogeneous feeding Burbot larvae, which were the pooled offpsring of many wild spawners, were reared from the first feeding (day 10 post-hatch) over a period of 20 days. Larvae of an initial size of 3.61 ± 0.27 mm (average TL ± SD; n = 15). 3.61 °C * day
