Denmark marine science: Fish atlas publication and trawling research debate

Denmark has seen significant scientific and media activity regarding its marine life and fishing practices. A major project has resulted in the ‘Atlas over danske saltvandsfisk’ (Atlas of Danish Saltwater Fish), a comprehensive 2,176-page work documenting all saltwater fish species within Danish waters. Developed since 2009 by the Statens Naturhistoriske Museum, DTU Aqua, and biologist Carsten Krog, the atlas aims to provide a baseline for monitoring fish populations and invasive species amidst a changing climate. The project received support from the Aage V. Jensen Nature Foundation and the Velux Foundation.

Parallel to these biological mapping efforts, a scientific debate has emerged regarding the impact of bottom trawling. A report titled ‘Effekter af fysisk forstyrrelse af bundtrawling på havbundens biodiversitet’ (Effects of physical disturbance from bottom trawling on seabed biodiversity), produced by researchers at Aarhus University's DCE with support from the Velux Foundation, has faced intense scrutiny. Recent media coverage in Jyllands Posten has focused on the integrity of the study's data and the influence of its funding sources, sparking discussions regarding marine conservation and the green agenda in Denmark.
