Summary
De danske økologiske landmænd kan se frem til at afsætte en del af deres proteinafgrøder til foder til økologiske opdrætsfisk. Fiskemel udgør p.t. den primære proteinkilde i foder til økologiske fisk. Fiskemelet fremstilles af industrifisk fra bæredygtige bestande, men dels er det ikke økologisk og dels er fiskemel en begrænset ressource.
Der er således behov for at erstatte så meget som muligt af fiskemels-proteinet med konkurrencedygtige økologiske vegetabilske proteinkilder, der både har et højt proteinindhold og en relevant aminosyresammensætning i forhold til fiskemel. I modsætning til konventionelt foder må der nemlig ikke optimeres ved at tilsætte kunstige aminosyrer til foder til økologiske fisk.
Summary translation
Danish grown organic plant crops may be used for feed for organic fish in the future. There is a need to replace the fish meal protein currently prevailing in the fish feed with competitive organic vegetable protein sources.However, it is requested that the alternative protein has a high protein content and an adequate amino acid profile in comparison to that of fish meal. In contradiction to conventional fish feed it is not allowed to add artificial amino acids to balance the amino acid profile in organic feed.
