Integrated ecosystem impacts of climate change and eutrophication on main Baltic fishery resources

The Baltic Sea is a heavily impacted ecosystem with multiple pressures acting simultaneously. In order to quantify impacts of integrated climate change and eutrophication under constant high fishing pressure, support decision-making policies in generating environmental economic sustainable systems, the Atlantis holistic mechanistic model was applied. overall aim run scenarios separate riverine nutrient load changes, taking into account interactions full food web entire Sea. This done identify which those two will likely dominate future ecosystem, test effects different forcing sources as well functions relation hydrographic spawning thresholds. By integrating hydrography, biology covering all trophic levels web, pressures, i.e. eutrophication, fishery, we were able evaluate relative 3 scenarios, using predict trends effects. With focus on major fish stocks, our model, its assumptions, indicated that loads are main driver changes long thresholds for not reached. If reached cod, impact become most important. Furthermore, higher resulted cod decrease, increase sprat herring. effect amplified by stronger change. Overall, it crucial importance fisheries stocks potential considered both dynamic ecosystem-based management approach.
