Abstract

The protective effect of dietary L-carnitine supplementation was accessed in turbot (Scophthalmusmaximus) challenged with Streptococcus parauberis. Infected fish fed 240mg L-carnitine showed significantly (P < 0.01) higher survival (78%) than infected fish fed 40mg L-carnitine (11%). When dietary L-carnitine supplementation was suspended, a significant increase in mortality was observed in infected fish. The present report documents that dietary L-carnitine fed on a continuous basis may act as an immunostimulant in turbot.
