Rearing enhancement of Ovalipes trimaculatus (Crustacea: Portunidae) zoea I by feeding on Artemia persimilis nauplii enriched with alternative microalgal diets

Abstract The southern surf crab Ovalipes trimaculatus (de Haan, 1833) presents a high potential for aquaculture. In this study, we analyze the benefits of different dietary treatments on its molt success and fitness of larval stages. Artemia persimilis nauplii were enriched with monospecific (Nannoc...
