Growth and survival of Octopus vulgaris (Cuvier 1797) paralarvae fed on three artemia- based diet complemented with frozem flish flakes crushed zooplankton and marine microalgae
During one month, paralarvae of common octopus (Octopus vulgaris) were fed 3 different diets: (1) Artemia sp. enriched with Isochrysis galbana (AI) complemented with sand eel (Hyperoplus lanceolatus) flakes (AH); (2) Artemia sp. enriched with crushed marine zooplankton (AZ); and (3) Artemia sp. cult...
