Traitement des effluents piscicoles marins par lagunage a haut rendement algal
Provedor de dados: 5
Autores: Pagand, Pascal.
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...

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...

Traitement par lagunage a haut rendement algal (LHRA) des effluents piscicoles marins recycles: évaluation chimique et écotoxicologique
Provedor de dados: 5
Autores: Deviller, Genevieve.
World aquaculture is a fast growing activity and the control of its waste becomes a key issue. Compared to traditional systems, recirculating systems allow to reduce replacement water and waste volumes. Nevertheless their effluents are more concentrated in dissolved nutrients (nitrate, phosphate). The high rate algae pond (HRAP) is one of the possible treatment technique to remove those nutrients. During this work, three rearing systems: one recycled, one recycled with HRAP and one open as a standard, were operated for one year to assess the impact of: (1) the reuse of treated effluent on survival, growth and nutrition of sea bass (2) the rearing system on fish health using multibiomarkers and trace metals accumulation responses and (3) best conditions for...

Fish growth and health aspects of sea bass (Dicentrarchus labrax) reared in standard vs. high rate algal pond recirculation systems
Provedor de dados: 5

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...
