Occurrence, distribution, and feeding habits of juvenile lumpfish, Cyclopterus lumpus L. in the Bay of Fundy
Juvenile lumpfish (< 55 mm length) occur in near-surface waters of the Bay of Fundy from July to September. Samples collected simultaneously with neuston and subsurface nets indicate that the juveniles occur primarily in the top few centimetres of the water column. Seasonal changes in distributio...
