Growth and survival of Octopus vulgaris (Cuvier 1797) paralarvae fed on three Artemia-based diets complemented with frozen fish 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...

Considering the highest dry weight obtained, the moderate high survival and the fact that with this diet it was possible to attain the adult stage, the AN diet was the most appropriate.

Regarding nutritional aspects, DHA content per se is not the only determinant factor for growth and survival of O. vulgaris paralarvae, but the presence of a high protein/lipid ratio and a high phospholipid content in the diet could possibly explain the better quality and strength of the paralarvae.
