Environmental Assessment of Seafood Products through LCA

Final report of a Nordic Network project

image of Environmental Assessment of Seafood Products through LCA

A network project run has gathered researchers in the field of Life Cycle Assessment (LCA) and seafood to discuss and develop methodology for LCAs of seafood products. Project participants represented national projects in this field in Finland, Sweden, Denmark, Norway and Iceland. The project has resulted in exchange of research results between the national projects and has constituted a forum for discussion of methodological issues for the participants. Methodological development has taken several important steps forward through this collaboration which are reported in this report as well as benefits of this development for the Nordic seafood sector. The report starts with a brief introduction to LCA methodology, continues with short reports about important environmental questions related to fishery and reports from the different workshops. Finally, a discussion of results, conclusions and a future outlook ends the report. Hopefully this will give a good picture of the status of LCA methodology for products coming from fishery and aquaculture.

Anti-fouling agents in seafood production

The chemicals, which have achieved most attention in the fishery is by far anti-fouling agents used to prevent algae and other marine organisms to settle and grow on the hull of the ships, also termed marine bio-fouling. Anti-fouling agents prevent marine biofouling, which otherwise would result in higher fuel consumption and lacking maneuvering capabilities. The biocides, which have been used so far, mainly consist of copper and/or tin compounds such as TBT, Zinc-pyrithione, Diuron and Irgarol (Lassen et al., 2001).
