Aquaculture and marine protected areas: Potential opportunities and synergies ArchiMer
Le Gouvello, Raphaela; Hochart, Laure-elise; Laffoley, Dan; Simard, Francois; Andrade, Carlos; Angel, Dror; Callier, Myriam; De Monbrison, David; Fezzardi, Davide; Haroun, Ricardo; Harris, Alasdair; Hughes, Adam; Massa, Fabio; Roque D'Orbcastel, Emmanuelle; Soto, Doris; Stead, Selina; Marino, Giovanna.
To meet the Convention on Biological Diversity's Aichi Target 11 on marine biodiversity protection and Aichi Target 6 on sustainable fisheries by 2020, as well as the Sustainable Development Goal (SDG) 2 on food security and SDG 14 on oceans by 2030, there is an urgent need to rethink how best to reconcile nature conservation and sustainable development. This paper argues for effective governance to support processes that apply principles of sustainable development and an ecosystem approach to decide about economic activities at sea such as aquaculture. It describes opportunities, benefits and synergies between aquaculture and MPAs as a basis for wider debate. The scope is not a comprehensive analysis of aquaculture and MPAs, but rather to present examples...

Associations between farming practices and disease mortality of Pacific oyster Crassostrea gigas in a Mediterranean lagoon ArchiMer
Pernet, Fabrice; Lagarde, Franck; Le Gall, Patrik; Roque D'Orbcastel, Emmanuelle.
We present the first large-scale, high-resolution spatial and temporal pattern of disease mortality caused by Ostreid herpesvirus 1 (OsHV-1) that has affected Pacific oyster Crassostrea gigas in France every year since 2008, in relation to local farm use. Mortality was monitored in healthy oyster spat deployed at 106 locations in the Thau Mediterranean lagoon during the epizootic that occurred in spring 2011. We conducted a field survey of farming practices in the areas where the sentinel oysters were placed before the epizootic. We found that the risk of disease mortality in sentinel oysters was higher within the bivalve farming area than outside it, suggesting that the infection pressure is much higher in areas with intensive farming activity. The risk...

Bioremediation of fishpond effluent and production of microalgae for an oyster farm in an innovative recirculating integrated multi-trophic aquaculture system ArchiMer
Li, Meng; Callier, Myriam; Blancheton, Jean-paul; Galès, Amandine; Nahon, Sarah; Triplet, Sebastien; Geoffroy, Thibault; Menniti, Christophe; Fouilland, Eric; Roque D'Orbcastel, Emmanuelle.
Integrated multi-trophic aquaculture (IMTA) systems are a promising solution for sustainable aquaculture combining nutrient recycling with increased biomass production. An innovative land-based recirculating aquaculture system (RAS) was studied in France for a 60-day experiment. It combined a European sea bass (Dicentrarchus labrax) RAS with two other production systems: high rate algal ponds (HRAP) with natural marine polyspecific algal assemblages, and oysters in separate open tanks. The objective was the assessment of: 1) the efficiency and the stability of the microalgae bioremediation of the effluent from a fish RAS in spring and summer, 2) the abundance and the diversity patterns of the microalgae biomass for consumption in the oyster compartment of...

Changes in planktonic microbial components in interaction with juvenile oysters during a mortality episode in the Thau lagoon (France) ArchiMer
Richard, Marion; Bec, Beatrice; Vanhuysse, Charles; Mas, Sébastien; Parin, David; Chantalat, Camila; Le Gall, Patrik; Fiandrino, Annie; Lagarde, Franck; Mortreux, Serge; Ouisse, Vincent; Rolland, Jean-luc; Degut, Anaïs; Hatey, Elise; Fortune, Martine; Roque D'Orbcastel, Emmanuelle; Messiaen, Gregory; Munaron, Dominique; Callier, Myriam; Oheix, Jocelyne; Derolez, Valerie; Mostajir, Behzad.
Oysters modify the planktonic microbial community structure by their filtration and NH4 excretion activities. While many studies have been conducted on this subject with adult oysters, none had been carried out in situ with juveniles. Pacific oyster juveniles (Magallana gigas, previously Crassostrea gigas) died massively all over the world since 2008 in relation with OsHV-1 infection. During mortality episodes, sick and dead oysters are not separated from healthy live ones, and left to decay in the surrounding environment, with unknown consequences for the nutrient cycle and planktonic microbial components (PMC). The present study aimed to elucidate for the first time the interactions between oyster juveniles and PMC during a mortality episode. Innovative...

Comparative growth and welfare in rainbow trout reared in recirculating and flow through rearing systems ArchiMer
Roque D'Orbcastel, Emmanuelle; Person, Jeannine; Le Bayon, Nicolas; Blancheton, Jean-paul.
The objective of this study was to compare fish performance and welfare at different stocking densities in a recirculating system (RS) and a flow through system (FTS) under field conditions. During the 77 days experiment, the fish survival rate was high (99.3%) and stocking density increased from 57 to 98108 kg m(-3). No significant differences in growth were observed between RS and FTS until day 56. Later, growth decreased in the FTS, while it remained similar to the farm reference at 50 kg m(-3) in the RS. Final weight was 17% higher in RS than in FTS. The maximum carrying capacity of the RS was near 100 kg m(-3), limited by NO2 increase up to safe level at the end of the experiment, the maximum carrying capacity of the FTS was near 85 kg m(-3), probably...

Comparison of two methods for evaluating waste of a flow through trout farm ArchiMer
Roque D'Orbcastel, Emmanuelle; Blancheton, Jean-paul; Boujard, Thierry; Aubin, Joel; Moutounet, Yves; Przybyla, Cyrille; Belaud, Alain.
European water legislation enforces increasingly restrictive measures with regards to reduction of water consumption and waste emission in order to minimise the potential environmental impact of the agro industry sector. Fish farms are particularly concerned, but legislation covering effluent discharge varies significantly from country to country. However, recommendations and directives from institutional, national or regional bodies suggest the enforcement of increasingly strict waste reduction measures and the development of waste treatment. Before treatment, it is necessary to evaluate waste production in terms of composition and quantity. The waste quantification methods used today for fish culture systems are either based on direct measurements of...

Lagarde, Franck; Fiandrino, Annie; Richard, Marion; Bernard, Ismael; Mortreux, Serge; Ubertini, Martin; Chiantella, Claude; Boj, Marie; Meddah, Slem; Leurion, Axel; Soriano, Solenn; Fuhrmann, Marine; Le Gall, Patrik; Chiera, Caroline; Berteaux, Tom; Guillou, Jean-louis; Roque D'Orbcastel, Emmanuelle; Perignon, Adeline; Bonnet, Delphine; Roques, Cecile; Bec, Beatrice; Cochet, Helene; Gervasoni, Erika; Miron, Gilles; Pouvreau, Stephane.
Since spat mortality events that were firstly detected in 2008, Mediterranean shellfish industry seeks to exploit the Pacific oyster spat from lagoon natural recruitment. The CRCM, Cepralmar and Ifremer developed accordingly a research project named PRONAMED Phase 1 and 2 - 2010-2014, in order to define the economic potential of spatfall and improve knowledge of the reproductive cycle of Crassostrea gigas in this specific environmental context. The results of the past three year‘s study (2012, 2013, 2014) showed that broodstock have the ability to provide larvae after sexual maturation and spawning. A coincidence was noted between moon phase (new and full moon) and spawnings with an amplifying effect of storms on the intensity of spawning (Ubertini et al....

Effect of environmental drivers on the reproduction of the pacific oyster Crassostrea gigas in the Mediterranean: The case of the Thau lagoon ArchiMer
Ubertini, Martin; Lagarde, Franck; Le Gall, Patrik; Mortreux, Serge; Pernet, Fabrice; Fiandrino, Annie; Pouvreau, Stephane; Roque D'Orbcastel, Emmanuelle.
The aquaculture of the oyster Crassostrea gigas is largely based on natural recruitment of the species on spat collectors along the french Atlantic coast, the remaining spat being provided by hatcheries and nurseries. Due to an increase in the climate/meteorological variability, during the last twenty years, the natural spat collection has become variable, from null to overabundant depending on the year. Since 2008, the oyster spat mortalities worsen the situation, reducing the available spat and increasing the cost of the latter. However, the temporal variability of the natural recruitment modalities in the Mediterranean do not allow the aquaculture industry to rely on native spats, making the understanding of natural recruitment in the Mediterranean a...

Effects of rearing density on sea bass (Dicentrarchus labrax) biological performance, blood parameters and disease resistance in a flow through system ArchiMer
Roque D'Orbcastel, Emmanuelle; Lemarie, Gilles; Breuil, Gilles; Petochi, Tommaso; Marino, Giovanna; Triplet, Sebastien; Dutto, Gilbert; Fivelstad, Sveinung; Coeurdacier, Jean-luc; Blancheton, Jean-paul.
During 84 days, the effects of density on juvenile sea bass (Dicentrarchus labrax) (76 +/- 16 g) were studied in an experimental tank-based flow through system. Performance, stress response and resistance to virus infection were analysed under five stabilized rearing densities: 10, 20, 40, 70 and 100 kg m(-3). Water quality parameters (CO2, total ammonia nitrogen and O-2) were measured and maintained close to the recommended values for farmed sea bass by adjusting water renewal exchange. No significant differences were observed between density treatments, neither on stress response (cortisol) nor susceptibility to nodavirus. With regards to biological performances, the daily feed intake and specific growth rate were significantly lower in fish reared at...

Cette étude avait pour objectif principal de déterminer les facteurs explicatifs de la dynamique spatio-temporelle des surmortalités d’huîtres creuses dans la lagune de Thau. Les facteurs étudiés étaient : la pathologie (détection d’ADN appartenant à l’Ostreid herpesvirus 1 OsHV-1 et au groupe bactérien Vibrio splendidus), l’état énergétique des huîtres (triglycérides, sucres totaux et acides gras comme marqueurs trophiques), les pratiques d’élevage et l’hydrodynamique. Afin de répondre à ces objectifs, nous avons suivi la mortalité d’un lot d’huîtres sentinelles, âgé de moins d’un an, maintenu indemne de mortalité, dans lequel on ne détectait pas d’ADN appartenant à OsHV-1. Le lot a été déployé mi-mars 2011 sur 106 stations dans la lagune de Thau, où les...

Fish, Algae, and Oysters: The Winning Trio in Aquaculture ArchiMer
Roque D'Orbcastel, Emmanuelle; Boudin, Elyse; Li, Meng; Carcaillet, Frédérique; Fouilland, Eric.
Most older methods of fish farming, or aquaculture, have focused on growing only a single species of sea life, for example, salmon. Modern aquaculture systems involve the cultivation of two or more species together, based on what happens normally in the food chain, so that one species can provide a source of food for another species in the farm. This article describes the results of an experiment combining fish culture with algae culture and oyster culture. We show that algae can grow using fish waste, and oysters can eat algae to produce good-quality, healthy food, which reduces the pollution generated by aquaculture.

Gametogenesis, spawning behavior and larval abundance of the Pacific oyster Crassostrea gigas in the Thau lagoon: Evidence of an environment-dependent strategy ArchiMer
Ubertini, Martin; Lagarde, Franck; Mortreux, Serge; Le Gall, Patrik; Chiantella, Claude; Fiandrino, Annie; Bernard, Ismael; Pouvreau, Stephane; Roque D'Orbcastel, Emmanuelle.
The Thau lagoon, located at the South of France, provides 10% of the French pacific oyster Crassostrea gigas production. Despite this intensive shellfish production, the larval recruitment of this species within the Thau lagoon is still misunderstood and spat collection remains highly variable; as a consequence, shellfish farmers rely mostly on hatchery”s spat. The present study aimed to describe reproduction features of C. gigas within the Mediterranean, as well as to explore spawning triggers of this species. To achieve this goal, the reproduction cycle from gametogenesis to spawning was followed during two years in several locations within the Mediterranean Thau lagoon. The spawning behavior of C. gigas within the Thau lagoon appeared to be slightly...

Guide méthodologique pour l'élaboration des dossiers de demande d'autorisation d'Installations Classées pour la Protection de l'Environnement (ICPE) en matière de pisciculture marine pour la région Corse ArchiMer
Roque D'Orbcastel, Emmanuelle; Sauzade, Didier; Ravoux, Georges; Coves, Denis.
Sea fish farms with production of more than 20 tons per year in France must obtain two operating licences: (i) one for Sea Farming (AECM), with the aim of ensuring that the granted site and use of the maritime public domain for exploitation will respect all restrictions of general interest; (ii) one for regulating Facilities Classified for the Protection of the Environment (ICPE). Although the first one requires a relatively simple licence request file, the second one demands a very complete file, which includes, beyond the notice of exploitation information, a complete impact study, as well as a hazards study and a health and safety notice. In this context, petitioners in Corsica (adjustment of status or new exploitation) are faced with the same...

Les piscicultures marines de plus de 20 t/an de production sont soumises en France à l’obtention de deux autorisations d’exploiter : (i) celle au titre des Cultures Marines (AECM), visant à s’assurer que le site concédé et l’usage du domaine public maritime pour l’exploitation permettent de respecter l’ensemble des contraintes d’intérêt général ; (ii) celle au titre de la réglementation des Installations Classées pour la Protection de l’Environnement (ICPE). Si la première nécessite un dossier de demande d’autorisation relativement simple, la seconde requiert un dossier très complet, qui comprend, outre une notice de renseignementssur l’exploitation, une étude d’impact complète, ainsi qu’une étude des dangers et une notice d’hygiène et de sécurité.
