In this study the suitability of various feeds in mass rearing of burbot Lota lota (L.) larvae under controlled conditions was determined. During the rearing the fish were fed with: artificial fodder, live Artemia nauplii and decapsulated cysts of artemia. The experiment continued for 20 days and it was conducted from hatching of the larvae. The initial density of fish during rearing was 1000 individuals dm⁻³. Rearing water temperature was set at 12℃. The parameters such as: average body length and height of the larvae and survival after completion of rearing period, were recorded. The Artemia nauplii proved the most suitable for feeding burbot larvae during the initial rearing. Additionally, high mortality of larvae was recorded during the period of filling the swim bladder.
