Vėgėlių (Lota lota (lineus)) jauniklių mityba ir jos pokyčiai skirtingomis aplinkos sąlygomis
The diet of burbot is analysed and described in this study. The aim of the study is to evaluate changes in burbot diet in different water temperature conditions. The following tasks were also set: to determine diet spectrum of the studied fish; to estimate detection rate of diet components; to compa...
