Abstract
Burbot Lota lota is an emerging aquaculture species, in which fungal infestations during early life stage development
are common. In this study, the tolerance of Burbot to external hydrogen peroxide (H2O2) treatment regimes was
examined during four early life stages to determine species and life stage-specific sensitivity. Yolk-sac larvae tolerated
three 1-h treatments up to 250 ěL/L H2O2 without significant reduction in survival. Preflexion larvae tolerated only
100 ěL/L H2O2 before survival was affected. In both cases, decreased survival was only observed after administration
of three consecutive treatments. Flexion larvae tolerated up to 250 ěL/L H2O2, but by the juvenile stage sensitivity
again increased to 100 ěL/L H2O2 before survival was affected. In these latter stages, decreased survival was observed
immediately following the first H2O2 treatment, suggesting a mechanism for toxicity that is different than that in
previous life stages. As has previously been shown, H2O2 can be effective for controlling aquatic bacteria and fungus
at or below 250 ěL/L, and our results indicate that H2O2 concentrations currently used during Burbot egg incubation
may be extended into the larval rearing stage for effective fungal control without negatively affecting survival of either
eggs or newly hatched larvae. Additionally, treatment regimes may be continued through juvenile development for
the purpose of controlling external pathogens in the hatchery production of Burbot.
