Última High-rate algal pond treatment for water reuse in an integrated marine fish recirculating system: effect on water quality and sea bass growth ArchiMer Deviller, Genevieve; Aliaume, Catherine; Franco, Miguel; Casellas, Claude; Blancheton, Jean-paul. 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<0.05) during the month of maximal climatic conditions for algae photosynthesis. After 266 days of experiment, mean fish weight was significantly higher (p<0.05) in the flow-through system than in the recirculating systems. Final fish weight was 15% higher in the...

The particulate matter plays an essential role in the functioning of recirculating aquaculture systems (RAS). Rich in organic substances, it provides ideal conditions for the bacterial development, which contribute to its mineralization. The understanding of interactions between the bio-geochemical cycles of carbon and nitrogen in these processes is necessary to define an effective and adapted management of aquaculture facilities. A methodology using natural stable isotopes (13C and 15N) and elemental carbon and nitrogen analysis on particulate matter, allows to identify its sources and to quantify its fluxes. Applying this methodology, we found an enrichment of 13C in dorsal muscle of reared fish and non differences of 13C in fish liver compared to the...
