Aquaculture in the High North in times of change

Nature based industries are of particular importance in the High North. Increasing demand on area, good locations, ocean temperatures and other environmental challenges have brought forward an expansion of aquaculture further north and into the ocean. The United Nations estimate the world population will be near to 10 billion by 2050, thus an increasing demand for food and energy by 70 – 100%. Shortage of fresh water, fertile land and nutrients, including phosphorus, will enhance the need for biomass from marine sources. Sustainable development of aquaculture is on the agenda. On a global scale seafood production from capture fisheries has already been surpassed by aquaculture. The sessions from this call will highlight the insights gained from recent research addressing challenges and opportunities:

  • Sustainable aquaculture in the high north in an age of climate change. Climate change can have a significant effect on global aquatic food production. Devising strategies to breed temperature-tolerant varieties combating existing and emerging diseases, reducing stress, and improving the welfare and health of farmed fish will help sustain the growth of the aquaculture sector. Thus, adopting new technologies for fish production and processing will be justified.
  • Coexistence in coastal waters – benefits and challenges offered. Coastal areas are already subject to an increase in competing activities and protection and are thus subject to conflict for space allocation. Multidisciplinary research approaches are needed to ensure better integration, sustainability, and synergies among activities in the coastal zone.
  • The use of new species in aquaculture. Norwegian aquaculture, for example, is synonymous with Atlantic salmon farming. The demand for salmon is expected to increase. However, the dependence on only one or a few species is not ideal for the economy of ‘the marine nation’. Efforts are underway to tap into new fish species for future farming and there is considerable increased interest to farm organisms lower in the trophic level, including macro and microalgae.
  • Future Food and Feed from Marine Sources. The increasing demand for seafood is the result of the awareness on the beneficial effects of seafood consumption on human health. Through aquaculture the nutritional content of the farmed species can be modified, especially in terms of omega-3 fatty acid. This necessitates tapping into new sources of feed ingredients of marine origin.
  • Safe and secure aquaculture farming operations in harsh conditions. Farming operations are moving into more exposed waters, and new farming systems are being developed in the northern hemisphere. As operations become complex there is a demand for new safe procedures which provide, health, safety, and environmental (HSE) challenges. To meet these new technologies for monitoring and surveillance, remote and autonomous operations need to be developed.

We welcome abstracts from studies that look at one or more of the topics above.
