Ecosystem services in freshwater fish production systems
and aquatic ecosystems: recognizing, demonstrating and capturing
their value in food production and water management decisions

The study developed a holistic assessment of different production and management scenarios in the inland capture fisheries and freshwater aquaculture sectors taking into account the (hidden) impacts, externalities and dependencies between fish production, environment and social and economic systems, and examining the full range of ecosystem services and trade-offs arising out of the use of aquatic ecosystems. The study took stock of the current state of knowledge on the multiple services (benefits) that fish production generates, globally and in three case studies in North America (Columbia River, CR), Asia (Lower Mekong Basin, LMB) and Africa (Lake Victoria Basin, LVB).

The case studies provided an analysis of the economic value of the provisioning, regulating, supporting and cultural services of inland capture fisheries and freshwater aquaculture under existing and alternative water management scenarios. This allowed for quantifying the changes in ecosystem services values arising out of management alternatives. The main ecosystem services considered in each system were: (I) Food production (animal proteins and nutrients); (II) Water quality; (III) Biodiversity; (IV) Carbon fixation and greenhouse gas emissions; (V) Nutrient cycling; and (VI) Income and livelihood support. Other ecosystems services were included where important.
