Water Quality Management
Ensuring the purity and health of the water in aquaculture systems is essential to prevent disease and promote the well-being of cultured organisms. This includes regular monitoring and management of water parameters like pH, oxygen levels, and pollutants.
Energy Efficiency
Sustainable aquaculture systems should aim to minimize energy consumption and rely on renewable energy sources where possible. This reduces the carbon footprint and makes the system more sustainable long term.
Responsible Use of Chemicals
Only essential chemicals should be used, following strict guidelines to minimize environmental impact and to ensure that no harmful residues remain in the aquaculture products.
Aquatic Biodiversity Conservation
Preserving the diversity of aquatic species and ecosystems is crucial to maintaining healthy aquaculture practices and avoiding negative impacts on wild populations and habitats.
Feed Management
Sustainable feed management includes using feeds that are from sustainable sources, properly balanced for nutritional content, and efficiently converted by the aquaculture species to minimize waste.
Legal Compliance
Adherence to all relevant laws, regulations, and international agreements is fundamental to ensure the ethical and sustainable operation of aquaculture systems.
Integrated Multi-Trophic Aquaculture (IMTA)
IMTA refers to the integrated farming of multiple species from different trophic levels in the same system. This mimics natural ecosystems and promotes resource efficiency by allowing waste from one species to be used as inputs (like fertilizer or food) for another.
Disease Management
Preventative measures, such as vaccination and good husbandry practices, should be prioritized over treatments with chemicals or antibiotics. Biosecurity measures help to prevent the spread of diseases between aquatic populations.
Employees' Well-being and Training
Ensuring the well-being and providing proper training for employees contributes to safer workplace environments and the successful operation of sustainable aquaculture practices.
Species and Stock Management
Careful selection and management of broodstock and juveniles, including genetic diversity considerations, are important for the sustainability and productivity of aquaculture systems.
Use of Native and Non-Invasive Species
Using species that are native or adapted to the local environment minimizes the risk of invasiveness and ecological disruption. It also ensures that the species are well suited to local conditions, which can improve farm productivity and sustainability.
Climate Change Adaptation
Aquaculture systems should be designed to be resilient to the effects of climate change, including considerations for extreme weather events, changing water temperatures, and sea level rise.
Waste Reduction and Management
Reducing waste through efficient feeding practices and proper disposal of farm by-products helps to maintain water quality and reduces the environmental footprint of the aquaculture system.
Market-Based Mechanisms
Utilizing certifications, eco-labeling, and market incentives can promote sustainable aquaculture by encouraging producers to meet higher environmental and social standards.
Stakeholder Engagement
Engaging local communities and stakeholders in the planning and operation of aquaculture systems fosters transparency, cooperation, and the protection of local interests and resources.
