Diet, prey selection, and growth of larval and juvenile burbot Lota lota (L.)
The diet, prey selection, and growth of larval and juvenile Oneida Lake burbot, Lota lota (L.), was investigated from the time of first hatch in mid‐April until their disappearance from the pelagic zone at the beginning of June. Mean length increased exponentially from 3–20 mm on 18 April to 15–00 m...
