Sampling aboard the Cuxhaven NC: A researcher’s experience with DFFU

The scientist, Katrine Wilhelmsen Melaa, boarded the Cuxhaven NC alongside a scientific observer from the Thünen Institute to gather data during a fishing trip in the Dohrn Bank, located between Iceland and Greenland. Her work focused on collecting stomach and stable isotope samples from two redfish species on the East Greenland Shelf for her PhD research.

Sampling the vessel for catch composition and biological parameters is part of the scientific observer programme by the Thünen Institute under the EU-Data Collection Framework (DCF). During the trip, the Cuxhaven NC 100 mainly targeted cod in the waters of Dohrn Bank. DFFU’s crew supported the scientist by providing access to the catch, enabling the collection of samples needed for the study.

In her blog post, Wilhelmsen Melaa shared insights into life aboard the Cuxhaven NC. “It was very interesting to hear the stories of the fishers, who have experienced so much variety from working at sea throughout the year, with the challenges that can arise when trawling and catching their target species,” she wrote. “The community on board was very supportive and welcoming, which boosted the morale when going through hard weather.” She also noted the value of seeing commercial fishing firsthand: “It was fascinating to see the commercial side of the fishery, coming from a research perspective, and to see how the results from the research we do in the Thünen Institute influences the quotas that fishing vessels like this follow.”

Her sampling involved measuring fish and preserving specimens for later analysis at the Thünen Institute. This experience gave her a practical understanding of commercial fishing operations. The crew’s cooperation ensured she could work efficiently, completing her tasks without interfering with their duties.

The trip offered practical benefits for both sides. The scientist completed her sampling without disrupting the crew’s operations, gaining valuable data to support her doctoral research. In return, DFFU’s team engaged with her work, learning about the scientific process behind fishery studies.

Alda Seafood values sustainability across our operations, from fishing to processing. Supporting scientific research aligns with our goal of working with partners like the Thünen Institute to ensure healthy fish stocks. The samples collected will contribute to knowledge about marine ecosystems, aiding fishery management practices.
