On the road to expertise: the electrofishing licence as the key to fish ecology

The aquatic world harbours a multitude of fascinating secrets and is of enormous importance for the ecological balance of our planet. Within this complex ecosystem, fish play a central role and their study and protection is crucial for the preservation of water quality. In his quest to develop his expertise in this field and contribute to the protection of aquatic habitats, Stefan Grosenick has decided to obtain an electrofishing licence. This step not only marks a milestone in his personal and professional development, but also a significant contribution to the research and conservation of our waters.

The EU Water Framework Directive calls for an ecological assessment of flowing waters, with fish playing a prominent role as indicators of water quality. Their sensitivity to environmental changes (such as those caused by cross structures in our watercourses and obstacles to the so-called "ecological continuity" increasingly endangering spawning migrations/genetic exchange) and pollutant inputs make them crucial indicators of potential issues in our water bodies. The electrofishing licence will enable Stefan Grosenick to record fish communities and thus lay the foundation for a comprehensive ecological status assessment. This qualification not only opens up new career prospects for him, but also strengthens his expertise in the field of fish ecology. His previous studies in aquatic biology have further deepened his interest in fish and their role in aquatic ecosystems. In particular, his research work on the fish community of a revitalised lowland stream in the Ruhr area has further ignited his passion for this field.

In addition to his academic work, he is also practically active in aquatic ecology, for example through his involvement in monitoring and analysing video footage in the Baldeneysee fish lift project. This practical experience has deepened his understanding of the complexity of aquatic ecosystems and strengthened his motivation to continue working in this field.
For Stefan Grosenick, obtaining an electrofishing licence is therefore not just a formal qualification, but an important step on his path to becoming an expert in fish ecology. He is firmly convinced that this additional expertise will enable him to make an even more significant contribution to the protection of our waters and establish himself as an expert in this field.
With this in mind, we are excited about the challenges and opportunities that this step brings for Stefan Grosenick and look forward to seeing how he can put his newly acquired skills and knowledge into practice to make a lasting contribution to the conservation of our aquatic habitats.
