Incidental bycatch in fishing gear affects a broad variety of marine fauna such as cetaceans, seals, seabirds, sharks and sea turtles. Altogether, this problem poses a serious obstacle to the ecologic and economic sustainability of marine fisheries. The conservation status of small cetaceans has worsened worldwide in the last decades. The harbor porpoise (Phocoena phocoena) as the only cetacean regularly occurring in the Baltic Sea is no exception to this. While several anthropogenic activities affect harbor porpoises in the Baltic Sea, bycatch in static fishing gear, especially in gillnets, represents the most notable one. The associated conflict between the need for fisheries, as an important protein source worldwide, and the resilience and health of our seas calls for action. Substantial development and research into bycatch mitigation strategies are required. The Thünen Institute of Baltic Sea Fisheries is currently working on three different innovative approaches that pursue one joint goal: to mitigate the bycatch of harbor porpoises in the German Baltic Sea. The aim of the workshop proposed here is to address this topic and to explore innovative technical devices: 1) acoustic deterrents like PAL (Porpoise Alert); 2) modification of gillnets like the “pearl net” (gillnet equipped with small plastic spheres to increase its acoustic visibility); 3) alternative fishing gears (fish pots and pontoon traps). To make this workshop an interactive experience, we will work with sound effects, as cetaceans are highly acoustic animals, and bring a PAL, pearl nets and traps for participants to interact with. We will further conduct a SWOT (Strengths, Weaknesses, Opportunities and Threats) analysis of the three proposed bycatch mitigation strategies. Moreover, we will organize a role game in which the workshop participants will form three groups, each of them representing a major stakeholder in this fisheries and biodiversity conflict. This workshop will allow participants to understand how multidisciplinary this field of conservation is, and how different stakeholders can work together to achieve a healthy and resilient ocean.
