Land-based production of sea bream (S. aurata) is one of the alternative types of aquaculture for different areas of the Mediterranean coast, but its future development will mainly depend both on the capacity to make this technology compatible with other uses of the land and the capacity to make it cost-effective, especially in comparison with production in cages. The present work analyzes all costs related to sea bream production in land-based facilities. With this aim in mind, a “standard facility”, growing 200 t per year of fish from 10 to 400 g, is defined. It is assumed that there will be a collective utilization by some farms of the infrastructure for intake, transport and outfall of water as well as the effluent treatment system. The work is developed for a specific area, The Ebro Delta in Spain, but intends to be a wide approach to the subject and to offer general conclusions. The average total production cost obtained, around four and a half euro per kg, allows us to consider that this type of technology is feasible under the conditions considered. The different items that could affect this cost are also discussed. Feed and juveniles represent respectively 30% and 25% of average total cost. Those costs differentiating between land-based and cage technology, i.e. oxygen and power, amount to only 6.3% of the average total cost.
