Up today, rearing of common octopus, Octopus vulgaris, paralarvae is severely limited by the lack of success during the paralarval stage, with generalised mor-talities occurring before the settlement of the juveniles. The use of on-grown Artemia cultured with the microalgae Isochrysis galbana and further enriched with Nannochloropsis sp. has proven a certain degree of success during the first month of life (Hamazaki et al., 1991). The present works aims at studying the effects of this rearing protocol on the lipid and fatty acid composition of paralar-vae, by comparison with a diet based on on-grown Artemia further enriched with a high polyunsaturated fatty acid (PUFA) oil emulsion.
