a partner (for my project)

Fish physiology, particularly nutritional physiology and nutritional requirements of a number of aquacultured species.

Extensive experience with intensive recirculated aquaculture systems (RAS) and development of bespoke RAS diets.

Extensive experience with biological documentation of raw materials utilized for aquafeeds, including sustainable raw materials.

Feed formulation and optimization of diets for Atlantic salmon, rainbow trout, gilthead seabream, European seabass, European eel and shrimp (Litopenaeus vannamei), including physiochemical characteristics of different raw materials on feed processability

PA3 - Climate-neutral, environmentally sustainable and resource-efficient blue food and feed

The project aims to assess the profitability of utilizing nutrients from jellyfish in feed for aquacultured fish species, and potentially also utilizing other components like collagen for human utilization (dietary/cosmetics);

1) Assessment of the geographical and temporal distribution of the most common species of jellyfish in the relevant sea basins - partner needed here
2) Development of mechanical/chemical methods for reducing water and possibly salt from primary product (precipitation and possibly centrifugation). Jellyfish contain approximately 97% water and it is therefore a prerequisite for profitable utilization of nutrients that these are concentrated into a secondary product as soon as possible after capture - partner needed here
3) Development of methods for fractionation, refining, concentration and drying secondary product to finished (tertiary) products (protein concentrates, marine lipids, collagens and/or phospholipids) - partner needed here
4) Chemical, biological and nutritional characterization of primary (jellyfish), secondary (dewatered product) and tertiary products (specific nutrient fractions), formulation of feed for biological experiments on fish, experimental feed production, biological laboratory-scale experiments on fish (trout or salmon), as well as reporting of biological experiments – including calculation of biological value of the various finished products. This is what DTU Aqua as a partner can contribute with.
