1. Understanding Fisheries and Aquaculture
What is ‘Fisheries’?
‘Fisheries’ refer to the industry involved in culturing, capturing, processing and selling of fish and other aquatic organisms from water bodies such as oceans, rivers, and lakes. It is subdivided into capture and culture fisheries.
What is Aquaculture?
Aquaculture, often erroneously referred to as fish farming, involves the cultivation of aquatic organisms under controlled conditions. This includes raising fish, crustaceans, molluscs, and aquatic plants in various environments such as ponds, tanks, or ocean enclosures. The goal of aquaculture is to enhance production through human intervention.
2. Similarities Between Fisheries and Aquaculture

The Interplay Between Fisheries and Aquaculture
While distinct, fisheries and aquaculture are interconnected. Aquaculture can reduce pressure on wild fish stocks, helping to sustain fisheries2. In some cases, fisheries may harvest wild fish to provide feed for aquaculture operations4. Both sectors can also intersect in supply chains and collaborate in regional food systems4
4. Differences Between Fisheries and Aquaculture
- Fisheries: Focus on culturing, catching, processing, and selling wild fish and shellfish.
- Aquaculture: Involves cultivating aquatic animals and plants.
2. Control Over Production
- Fisheries: Harvesting from existing aquatic populations.
- Aquaculture: Purposeful cultivation and harvesting of aquatic plants and animals.
3. Sustainability
- Fisheries: Harvesting wild fish/shellfish, or raising/harvesting fish through aquaculture or fish farming.
- Aquaculture: Considered a way of sustaining wild fisheries’ stock.
4. Environmental Impact
- Fisheries: Concerns include overfishing, habitat destruction, and bycatch involved with capture fisheries.
- Aquaculture: Issues can include water pollution and disease if poorly managed. E.g. eutrophication and chemical and biological pollution after pond fertilisation.
5. Types and Products
- Fisheries: Can be saltwater or freshwater, wild or farmed.
- Aquaculture: Can be mariculture or integrated multi-trophic.
6. Sustainability and Stock Decline
- Fisheries: About 90 percent of fish and shellfish are harvested through wild fisheries.
- Aquaculture: Aquaculture is considered a way to sustain these wild fisheries’ stock as the wild fisheries’ stock has seen a decline in recent years.

Conclusion
In summary, while fisheries and aquaculture operate through different methods—wild capture versus controlled cultivation—they share significant similarities that underscore their importance in global food systems. Both sectors contribute to economic stability, food security, sustainability efforts, environmental interactions, and technological advancements. As the global population continues to grow, understanding these similarities will be crucial for developing integrated approaches that enhance seafood production while protecting marine ecosystems.
By fostering collaboration between fisheries and aquaculture, we can ensure a sustainable future for our oceans and the communities that depend on them. By recognising the interconnectedness of fisheries and aquaculture, stakeholders can work towards more sustainable practices that benefit both industries while ensuring food security for future generations.
Note: While fisheries traditionally focus on wild catch and aquaculture on controlled farming, modern practices increasingly blur these lines. For instance, some fisheries incorporate aquaculture techniques (e.g., hatcheries), and aquaculture often relies on wild-caught juveniles or feed. Collaborative approaches, such as integrated multi-trophic aquaculture, highlight their potential synergy in sustainable food systems.
Understanding the differences between fisheries and aquaculture is essential for making informed decisions about seafood consumption and supporting sustainable practices. While fisheries rely on harvesting wild populations, aquaculture offers a controlled and potentially more sustainable alternative. As the demand for seafood continues to rise, both fisheries and aquaculture will play crucial roles in ensuring a stable and environmentally responsible supply.
By embracing responsible practices and innovative technologies, both sectors can contribute to a healthier planet and a more secure food future.
