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 ... DEVILLER, Genevieve http://biblioteca.universia.net/ficha.do?id=4045015 A high-rate algae pond (HRAP) was tested as a second loop of water treatment in a recirculating fish rearing system to reduce water requirements and nutrient discharge levels. Three duplicated groups of sea bass (mean initial body weight 3 5 I I g) were reared under different system conditions (flow-through system, recirculating system and recirculating system with HRAP) for I year. Fish survival rate was higher in the system with HRAP, and their mean body weight was statistically higher (p DEVILLER, Genevieve; ALIAUME, Catherine; FRANCO, Miguel; CASELLAS, Claude; BLANCHETON, Jean-Paul http://biblioteca.universia.net/ficha.do?id=21496438 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 w...

Sigma 2,3,7,8-PCDD/F and Sigma 7ICES PCB air concentrations (0.2-1.4 and 31-57 pg m(-3), respectively) were typical of rural areas. Concentrations in the water column were very low for PCDD/Fs (163-476 fg L-1) and low for PCBs (138-708 pg L-1). PCDD/F and PCB concentrations found in surface sed...
