Recirculation systems represent an important technological improvement of traditional aquaculture, in terms of environmental impact and of product quality. In this type of structure, effluent from fish tanks is regenerated by filtration and settlement, stabilized to reach standard chemical and physical parameters, and re-used to refill tanks.
\nMain advantages are: reduced environmental changes inside the tanks, partial protection of product from pollution by toxicants (even toxic algal blooming), lesser food escape, water consumption and effluent volume. Request for new water is dependent from leakage, accidental or during washing procedures of tanks, and approximate only 5% ca of the total volume of the implant.
\nTwo main types of re-circulation systems are produced: closed water type is more apt for experimental, low productive structures, and open-sky implants, used for commercial production.<\/p>\n
