Objectives of the course:
Mussel mitigation cultures can actively be used to mitigate effects of excess nutrient run-off from land. Mussels possess a significant capacity for clearing the water column of particles and are thereby bounding nutrients in their tissue. Harvest of the farmed mussels will imply a return of the bound nutrients back to land thus reversing eutrophication. In addition, the clearing of the water column increases environmental quality.
There may, on the other hand, be negative effects through increased sedimentation of biodeposits locally below the farms increasing the oxygen consumption and changing the sediment chemistry. Hence, it is important to choose the most appropriate locations for an optimal impact of mussel mitigation cultures on the environment. In the site-selection process of mussel farming, it is also necessary to consider multiple conflicting interests and physical, ecological and legal aspects of the site.
During the course, different modelling methods for estimating mussel growth (bounding of nutrients) and environmental effects in different ecosystems are presented and discussed. The students will work in groups on different case studies and use existing modelling tools to identify optimal sites for location of mussel mitigation cultures. In addition, the concept of Ecosystem Services will be used to identify implications of mussel mitigation cultures on social-ecological systems in coastal areas. Within group exercises, the ecosystem services assessment tool (ESAT) will be applied combined with a stakeholder preference and planning tool to explore how the concept can be used to support decision-making within stakeholder groups.
Learning outcomes and competences:
At the end of the course, the student should be able to:
- further explore the concept mussel mitigation cultures in other areas
- estimate growth potential of mussels by modelling
- estimate the effects on water quality due to mussel mitigation cultures by modelling
- identify areas suitable for mussel mitigation cultures
- use the concept of ecosystem services to assess impacts of mussel mitigation cultures
- apply different tools to support decision-making processes
