Lota lota Spawning conditions Spawning season Burbot spawn in winter time at a temperature of 1-4°C ['February', 'March', 'January']
Leuciscus idus Larvae Temperature during larval development 19-20 19.5 °C
Lota lota Larvae Temperature during larval development Food intake by burbot larvae begins when water temperature is above 8°C. […] larvae could tolerate up to a temperature of 20°C. The temperature of spring water was 12 ± 1°C upon release of the larvae but gradually adjusted to 16 and 20°C. […] High survival of burbot larvae at a higher temperature in the first 10 days of the experiment suggests that embryos (incubation temperature before the hatching was 4 ± 1°C) and larvae differ in their physiological tolerances. [...] It seems that the most appropriate temperature for successful burbot larvae culture is ranged between 12 and 16°C, and represents a trade-off between faster growth with higher mortalities at higher temepratures and slow growth, but higher survival at lower temperatures. 12.0 °C
Lota lota Larvae Reaction to light Survival data reveal that burbot larvae survive better under light condition compared with dark. […] a positive reaction to light by burbot larvae would be replaced by a negative phototactic at the later stage of development. Photopositive
