Research area 3: Development of environmentally friendly culture techniques
Summary
Researcher in charge
Henrik Pavia
Challenges
Conventional open-cage mariculture currently provides significant amounts of high-value marine protein, but has detrimental environmental effects through nutrient release when finfish, crayfish and mollusks are being fed, through genetic, pathological and parasitic interactions with wild populations, and through the use of wild-harvested fish for feed production. There is thus an urgent need to develop novel, high-productivity cultivation models without exceeding the system-specific carrying capacity.
Objectives and expected outcomes
• To increase the diversity of cultured species, through development and validation of optimal conditions for full lifecycle farming of new mariculture species from different trophic levels.
• To develop novel techniques that combine local mariculture and feed production (RA 4), thereby recycling nutrients and raw material to create more self-sustained production systems.
• To test and provide recommendations for novel, multi-trophic mariculture models.
• To provide empirical data and parameters that allow for rigorous modeling of environmental and economical sustainability, as well as assessment of social acceptance (RA6)
• To develop novel, sustainable, circular multi-trophic cultivation systems, with new matching methods to evaluate environmental carrying capacities as well as social acceptance (RA1, RA2, RA6).
