Towards an Expansion of Sustainable Global Marine Aquaculture

There is a need for more food for humans as the global human population on and their buying power continue to increase the decades to come. Aquaculture in the sea delivers nutritious, protein and essential lipid rich food and is believed to be a promising means for increasing global food production. Further expansion of marine aquaculture requires new feed resources, an increasing challenge acknowledged by science and feed manufacturing industry. Most cultured fishes are from nature carnivore animals with high nutritional requirements. A viable road map for further expansion of mariculture to support human food production can be to focus more on non-fed aquaculture while still maintaining efforts to establish new feed resources. Non-fed, or extractive aquaculture, mostly deals with low trophic animals and seaweed farming, which is a well-known example. Non-fed aquaculture is dominant method in most Asian countries, like in China.



It is an overall goal to increase sustainable food production from the oceans and to establish a roadmap describing a main strategy to reach that goal. Marine aquaculture is a relatively young industry, facing broad challenges of environmental, economic and social sustainability. There is a need to improve animal welfare and public perception. New feed resources are needed for most farmed marine species. Many countries share the challenge of establishing new feed resources. Non-fed aquaculture of for example seaweed, shellfish, crustaceans, sea cucumber and sea urchin, is the dominant method in many Asian countries while intensive fish farming of salmonids, seabass and sea bream are more dominant in Europe. A main challenge is to cooperate across regions and learn from each other.

The AQUANOR 2023 conferences will treat the mentioned scientific issues in the following sessions:

1. Feed resources for future expansion of aquaculture

2. Non-fed extractive aquaculture – species with aquaculture potential and their cultivation techniques

Sessions are interwoven, among others because non-fed aquaculture may support feed resource produced for carnivore fish. The sessions will cover aspect of management, societal, engineering, and scientific aspect. Both digital and physical lectures are accepted. for publication.



The Research Topic "Towards an expansion of sustainable global marine aquaculture" invites paper submission by authors registered for AQUANOR 2023 and by this the conference. (https://gyroconference.eventsair.com/aqua-nor-2023). The session chairs will select the papers for oral presentation, oral digital presentation, and papers of adequate quality not accepted for oral presentation because of space limitation. Digital video files will become displayed in the AQUANOR web pages. Examples of topics invited for are:

1. Feed resources of captured fish and other marine animals including their by-products and wastes cycles

2. Feed resources of farmed seaweed and marine low trophic animal species.

3. Single cell derived biomass and refined products from industrial biotechnology,

4. Human food derived from farmed non-fed low trophic level species, e.g., including shellfish, crustaceans, other invertebrates, omnivorous fishes, seaweed and more.

5. Low trophic aquaculture through seeding and harvesting the sea, ocean farming

6. Aspects of environmental, economic and societal sustainability of new feed resources and human food from farmed low trophic organisms
