Study Notes
Marine Food Systems and Aquaculture
- Learning outcomes include defining marine food systems, understanding sustainability and circularity, recognizing diverse contributions to sustainable food, applying environmental/social indicators for assessment, discussing trade-offs and synergies between food systems, and designing sustainable seafood production strategies.
- Marine food systems are intricate networks of interconnected components, including production, distribution, preparation, and consumption.
- Food systems encompass the socio-economic and environmental outcomes of these activities. A food system is a Socio-Ecological System (SES) integrating human and natural systems.
- Food systems have changed over time, evolving from more traditional, smaller-scale systems to larger-industrialized ones.
- Global food systems are complex, with activities interconnected across regions and countries.
Introduction to Marine Food Systems
- A marine food system is a network of integrating components that work together to produce, distribute, and consume seafood.
- Key components include production, distribution, preparation, and consumption of seafood, along with the socio-economic and environmental impacts.
- Different types of seafood, including finfish, molluscs, crustaceans, and echinoderms, are part of marine food systems. Seafood is also sourced via aquaculture and capture fisheries.
- Aquaculture involves producing seafood in controlled environments while capture fisheries involve harvesting wild fish.
Food System Activities and Components
- Food systems comprise interconnected activities (e.g. production, storage, consumption) with key components (socio-economic, environmental).
- Drivers include social and environmental factors, such as increasing global population leading to increased demand.
- Outcomes result from these activities, and include socio-economic factors (livelihoods and incomes) and environmental impacts.
Marine Food Systems
- Marine food systems encompass diverse species, including finfish (e.g., cod, salmon, tuna), molluscs (e.g., oysters, mussels), crustaceans (e.g., shrimp, crab), and aquatic plants (e.g., seaweed).
- Seafood is sourced through both capture fisheries (harvesting wild fish) and aquaculture (raising seafood in controlled environments).
Aquaculture
- Aquaculture production has increased significantly since the 1990s, surpassing fisheries in some cases in total aquatic animal production.
- Different aquaculture types are categorized based on water type (e.g., freshwater, brackish water, saltwater).
Seafood Production and Consumption
- Seafood consumption is driven by factors like dietary health benefits (e.g., omega-3 fatty acids), livelihoods, and cultural practices.
- The demand for seafood is a major driver for both aquaculture and capture fisheries.
Sustainability and Circularity
- Sustainable marine food systems balance environmental and social impacts with positive outcomes.
- Circular economy principles aim to minimize waste and maximize resource use throughout the food system.
Challenges in Aquaculture
- Environmental challenges such as land use change, water pollution, and eutrophication are associated with certain aquaculture practices.
- Various socio-economic factors like working conditions, labour practices, and social inequalities also influence this sector.
- Overfishing and stock depletion are also threats to capture fisheries based seafood systems.
Sustainable Practices
- There are various sustainable practices to reduce the environmental and social impact from aquaculture and fisheries-based seafood systems.
- Efforts towards eco-friendly practices that minimize waste and stress on the environment, such as reducing feed use, using recycled water and reducing bycatch (unwanted organisms caught in fisheries) are also key objectives towards creating sustainable practices.
Ecological Benefits
- Regenerative aquaculture can restore ecosystems positively impacting biodiversity and the overall environment.
