Abstract
Fish sludge (faeces and fish residues from farmed fish) is currently not permitted as an ingredient in CE-marked fertilising products under the EU Fertilising Product Regulation No. 2019/2009 (FPR). This report provides the scientific basis for a potential proposal to include fish sludge in the FPR by 1) summarising existing knowledge on contaminant levels and the agronomic efficiency, and 2) identifying knowledge gaps. The legal status of fish sludge under the Animal by-products regulation (EU) No. 1069/2009 (ABP) has to be clarified first but is outside the scope of the report. Most available data on fish sludge originate from land-based Atlantic salmon production in Norway. A major knowledge gap is therefore the lack of data on contaminant levels and the agronomic efficiency of fish sludge from sea-based systems, as well as from other countries and aquaculture species. With respect to contaminant levels in fish sludge from land-based smolt systems in Norway, additional data are required for hexavalent chromium, inorganic arsenic, pharmaceuticals, and certain pesticides. The agronomic efficiency of fish sludge from land-based smolt systems in Norway is relatively well documented.

Upstream Energi vil lage biokol av fiskeslam. Det er ei dårleg løysing, meiner NIBIO-forskar Eva Brod.
