Última High rate algal pond treatment for water reuse in a marine fish recirculation system: Water purification and fish health ArchiMer Metaxa, Elisabeta; Deviller, Genevieve; Pagand, P; Alliaume, C; Casellas, C; Blancheton, Jean-paul. 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...

Ano: 2006 URL: http://archimer.ifremer.fr/doc/2006/publication-2306.pdf Temporal study of estrogenic responses of mussel (Mytilus galloprovinciallis) extracts applied to reporter cell lines ArchiMer David, A; Dagnino, S; Pichot, Yves; Munaron, Dominique; Escande, A; Casellas, C; Fenet, H; Gomez, E. In vitro bioassays would facilitate monitoring of estrogen-like compounds in mussels (Mytilus galloprovincialis) since they tend to accumulate lipophilic compounds in their fat and muscle tissue. However, estradiol (E2) steroid (already identified in mussels) could induce false positive responses. This study focuses on temporal variability in estrogenic responses of mussel extracts and the possible relation of this response with E2 levels. The reproductive cycle and growth were thus monitored for six months in sexed mussels. E2 levels were similar between genders and these levels varied with reproductive stages. human estrogen receptor (hER) activities were similar at all stages except in February. E2 present in male and female extracts accounted for part... Tipo: Text Palavras-chave: ELISA; Reporter cell lines; Mytilus galloprovinciallis; Estradiol; Biomonitoring. Ano: 2008 URL: http://archimer.ifremer.fr/doc/2008/publication-4578.pdf The use of high rate algal ponds for the treatment of marine effluent from a recirculating fish rearing system ArchiMer Pagand, Pascal; Blancheton, Jean-paul; Lemoalle, J; Casellas, C. A high rate algal pond (HRAP) system was used to treat effluent from a recirculating sea water aquaculture system in southern France. Dicentrarchus labrax L. were farmed at a high density, with effluents containing an average of 10 mg L-1 dissolved inorganic nitrogen (DIN) and 1.3 mg L-1 reactive phosphorus (RP). On a yearly basis, the algal pond removed 59% of the dissolved nitrogen and 56% of the phosphorus input, which was converted into 3.3 kg DW m(-2) algae. Green macroalgae were dominant throughout the year and the algal biomass mirrored the seasonal changes in daily irradiance and temperature. This first year study supports the possibility of treating marine aquaculture wastes using HPAPs, although conditions will have to be found to mitigate the...
