Startfôr til juvenil edelkreps (Astacus astacus)
Kasa Krepseoppdrett på Hvaler har valgt å satse på en halvintensiv modell for produksjon av edelkreps. Ved bruk av halvintensiv produksjonsmodell kreves det et egnet fôr til juvenile kreps. Det som har vært vanlig å bruke, er levendefôr ved bruk av Artemia i kombinasjon med vegetabilske næringsstoffer som modnet laug, grodd hvete og potet.
