PRODUCTION SYSTEMS AND AREAS

Types of Aquaculture Production

The entirety of aquaculture production is made up of a range of different species, which, being creatures with very different requirements, require specific production systems for each species. These range from the production of macroalgae and molluscs in floating systems placed in the open sea, to tanks in which water flows from rivers for the production of trout and other salmonids or floating cages in seas, rivers and lakes for the cultivation of various fish species. In this century, the most technological systems are expanding rapidly, examples of which are: closed recirculation systems for growing fish or photobioreactors for growing various species of microalgae.

OUR PRODUCTION

The production of sea bass and sea bream

These producers come from a semi-intensive system in which the fish is raised in earthen tanks – esteiros – where water renewal is mainly done by the effect of the tides. These tanks constitute very rich semi-natural ecosystems in which numerous accompanying species develop, with very interesting biological interactions, because some serve as natural food for fish in production, while others grow and reproduce by emitting juveniles into the natural environment (bivalve larvae and polychaetes, for example) or where there is the production of microalgae that are emitted into the natural environment, feeding the wild populations in the surrounding environment or the natural production of macroalgae that the sea bream consume, giving them their characteristic color and flavor.
