New International Study Reveals Crucial Impact of Water Temperature on Lumpfish Location, Especially Outside Spawning Season REYKJAVIK – Recent research, a collaborative effort between scientists from Iceland, Greenland, the Faroe Islands, Denmark, and Norway, has highlighted that water temperature is the predominant environmental factor influencing the distribution and abundance of lumpfish (Cyclopterus lumpus) in the North Atlantic, particularly during summer. While it was known that this species spawns in coastal waters, its distribution outside the breeding season was poorly understood. The study, recently published, utilized data from an extensive annual pelagic trawl survey conducted in the Nordic Seas, known as the International Ecosystem Summer Survey of the Nordic Seas (also called the mackerel survey). The results reveal that lumpfish have an extensive dist... FULL STORY
