  • Phosphatase activity and specific methanogenic activity in an anaerobic reactor treating sludge from a brackish recirculation aquaculture system

    Anaerobic treatment of high salinity sludge from marine/brackish recirculation aquaculture systems is potentially limited by inhibition of enzymatic activities and cell lysis resulting from high osmotic pressures. To further address these limitations the following investigations were conducted: effect of salinity on phosphatase activity (PA), soluble microbial products (SMP) production, and ...

  • Aquaculture and sustainable development: a regulatory or governance system?

    Governance is defined as a process allowing actors to contextualise the regulatory system and, as a result, to transform sustainable development (SD) into an instrument of action. It will be all the easier for actors to familiarise themselves with SD and its implementation measures if these measures are similar to their representation on SD and its consequences on their activity and social life. ...

  • Aquaculture Facilities As A Potential Source Of Antibiotic Resistance To The Aquatic Environment

    The development and proliferation of antibiotic resistance in pathogenic, commensal, and environmental microorganisms is a major public health concern. The extent to which human activities contribute to the maintenance of environmental reservoirs of antibiotic resistance is poorly understood. Aquaculture facilities are one possible source of resistance to the environment because of their ...

  • Performance of an in-situ rotating biological contactor in a recirculating aquaculture system

    The start-up and activation of a nitrifying rotating biological contactor (RBC) and its performance inside a culture tank of rainbow trout were studied. First, in a lab-scale operation, the system was fed with a synthetic medium containing a high ammonia concentration (567 mg NH4+-N L−1) and operated at a high hydraulic retention time (HRT) (6.5 days) to minimize the wash-out of the biomass and ...

  • Development of new methods to assess invertebrate immunology and immunotoxicology in aquaculture: oysters and lobsters as examples

    In order to support healthy aquaculture, we developed assays to assess immune functions and their susceptibility to environmental conditions or toxicants. Flow cytometry allowed the rapid and quantitative analysis of oyster and lobster cell subpopulations and their functions (phagocytosis, peroxide production, natural killer cell-like activity and apoptosis). We demonstrated experimentally that ...

  • Shrimp farming: Why prevention is better than medicine

    Disease challenges that have affected a number of key shrimp production regions around the world in recent years have increased the focus on producing healthier and more robust stocks. In addition to establishing very strict sanitary requirements, many shrimp farmers have sought new health-specific diets across the shrimp lifecycle that progress growth and reduce bacterial challenges. Some, ...

  • Hexabromocyclododecane in consumer fish from South China: Implications for human exposure via dietary intake

    Levels of hexabromocyclododecane (HBCD) were determined in 12 consumer fish species from South China. The concentrations of the sum of HBCD diastereoisomers (ΣHBCD) ranged from nondetectable to 194 pg/g wet weight, with a detectable frequency of 70%. This was at the low end of the concentration range globally observed. Carnivorous fish species contained higher HBCD concentrations than herbivorous ...

  • Eutrophication: Sources and drivers of nutrient pollution

    Nutrient over-enrichment of freshwater and coastal ecosystems, or eutrophication, is a rapidly growing environmental crisis. Worldwide, the number of coastal areas impacted by eutrophication stands at over 500. In coastal areas, occurrences of dead zones, which are caused by eutrophic conditions, have increased from 10 documented cases in 1960 to 405 documented cases in 2008. In addition, many of ...
