Abstract: Octopus vulgaris on-growing in floating cages has shown promising results. Nevertheless, some aspects of the culture system need to be evaluated to warrantee its profitability. In the present work individual and group rearing, in PVC net compartments and floating cages respectively, are compared under two dietary treatments. One diet is composed by bogue, supplied as ?discarded? species from local fish farms, and the other is based on a 40-60% discarded bogue-crab Portunus pelagicus. Besides, the effect of initial size is also evaluated. All octopuses were PIT-tagged and the experiment lasted 2 months. Absolute growth rate (AGR, g./day) and mortality (%) were calculated. Control diet generated higher growth rates and lower mortality which suggests different crab requirements at higher rearing temperatures. High mortality recorded in individual rearing could be related with high initial rearing density and temperatures.
