ShellFeed – Risk assessment of algal toxins in new marine feed sources for salmon

Background: About 92% of the raw materials used in Norwegian aquafeeds are currently imported. Shellfish can be a valuable local marine resource, but are regularly contaminated with algal toxins.

Objective: Provide knowledge about the toxicity of the algal toxins (OA/DTXs and STXs) in salmon after dietary exposure, and potential carry-over of these toxins or their metabolites into fish fillets or by-products
