From nose to tail fin- smarter use of seafood by-products generated in Sweden

ABSTRACT

Although by-product generation in Swedish seafood production does not represent major volumes or values internationally, their fate has a significant influence both on the environmental and economic sustainability of the production. In some cases, the economic margin of by-products used for feed is higher than of seafood products, in which case it may even be hard to tell what is the main and by-product, respectively. We quantified biomass flows arising in Swedish fisheries and seafood processing and their current use and value. Interviews demonstrated a number of hurdles to more high-value use of by-products. We then hypothesize a number of future scenarios that maximize food use, value generation and one that is more realistic in between and quantify products, values and environmental impacts generated in each scenario as a basis for a discussion of needed measures to improve the resource utilization and profitability of the Swedish seafood sector.
