| Recirculation aquaculture system (RAS) is the type of land-based aquaculture production that interferes the least with the environment, particularly due to low effluent volume and overall water requirement. Water reuse, sometimes limited by the accumulation of waste products excreted by fish, can be improved by incorporating another biotechnical component in the form of high rate algal pond (RAS+HRAP), thus adding to the economy and self sustainability of the system. Our goal was to evaluate whether rearing fish for 1 year in a RAS or RAS+HRAP led to differences in fish production and health, by assessing: (1) fish growth; (2) impact on the morphological structure of sea bass target tissues (liver, kidney, and spleen); (3) susceptibility to monogenean... |

| Regardless of the degree of closure of a recirculation system, effluents are produced and replacement water is needed, which limits the possibility of locating a seawater production system away from the shoreline. At the Palavas Ifremer station, in the south of France, a High Rate Algal Pond (HRAP) was operated during several years to treat the effluent from a recirculating aquaculture system before reusing it. The effect of the HRAP-treated water on the recirculation system and on the fish was investigated and the optimal algae growing conditions were defined. The experiments were carried out in three rearing systems: one flow through, one recirculating and one recirculating with a HRAP. The water flow rate, temperature, pH and salinity conditions were... |

| When facing the increasing development of aquaculture, farming in recycled water is an alternative to limit the impact on the environment: farming produces a lower amount of wastes but of higher concentration which can be treated. The goal of this thesis is to evaluate the efficiency of high rate algal lagooning/ponding (HRAP) for the treatment of marine fish culture effluents. Also, this study utilizes wastes from Dicentrarchus labrax grown in Ifremer's recycled waters station. The first step shows the particularities linked to recycled water farming effluents. They are characterized by low particle and organic substance concentrations as well as strong dissolved inorganic nitrogen (DIN) and phosphorus (DIP) concentrations. Furthermore, nitrogen is mainly... |
