Provedor de dados: 5
Autores: Abdou, Khaled; Le Loc'H, Francois; Gascuel, Didier; Romdhane, Mohamed Salah; Aubin, Joel; Ben Rais Lasram, Frida.
Purpose The present study assesses environmental performance of seafood production by demersal trawling in Tunisia (Gulf of Gabes) in order to analyze the contribution of each production stage to environmental impacts and to understand drivers of the impacts using life cycle assessment (LCA). Then a set of ecosystem quality indicators were determined using an ecosystem modeling tool, Ecopath with Ecosim (EwE), and were combined with LCA to increase the relevance of both tools' assessments when applied to fisheries. Methods The approach consisted of conducting LCA and calculating ecosystem indicators to provide a complete assessment of trawling's environmental impacts and the ecosystem characteristics associated with seafood production. The functional unit...

Little work dealing with the evaluation of aquaculture system sustainability has so far been undertaken on a global and comparative basis. Moreover, such work is mostly based on very unbalanced approaches in terms of the dimensions of sustainable development that are taken into account. The approach adopted in this article is designed to encompass all the dimensions of sustainability including the institutional one (governance). The taking into account of this latter, in particular, together with the role played by aquaculture in sustainability at the territorial level gives the approach its original and innovative nature. The process of establishing the checklist of sustainability indicators in aquaculture relies on a hierarchical nesting approach which...

It cannot be said that aquaculture has ignored sustainable development (SD), judging by the number of standards, guides and indicators devoted to it, produced mainly under the aegis of international organizations such as FAO, The European Union and sorne NGOs. However, these continue to be perceived in large measure as constraints rather than as shared objectives by actors. Faced with this situation, which is not specific to aquaculture but on the contrary quite general regardless of sector, context or scale, the authors seek to propose a generic approach that through a collective process, i.e. a co-construction, promotes the implementation and appropriation of SD. What makes this approach original is not only the participatory nature of the construction,...

World aquaculture is growing (+ 8% per year) to meet the increasing demand of fish for human consumption that capture by fisheries can no longer cover. Consequently, the need for aquafeed and feedstuffs is rising while volumes of fishmeal and fish oil, the traditional aquafeed ingredients, remain stable. More and more fishmeal and fish oil are substituted by plant products. Between 80 and 95% of fish meal can be replaced by a combination of plant protein sources providing the indispensable amino acids in sufficient quantity to meet the fish needs. Beyond this substitution rate, feed intake, feed efficiency and growth rate decrease and metabolic changes are observed despite the diets containing all the required nutrients. Fish oil can be replaced by a mix...

Linking swimming performance, cardiac pumping ability and cardiac anatomy in rainbow trout
Provedor de dados: 5
Autores: Claireaux, Guy; Mckenzie, David; Genge, A; Chatelier, Aurelien; Aubin, Joel; Farrell, Anthony.
We exploited the inherent individual diversity in swimming performance of rainbow trout Oncorhynchus mykiss to investigate the hypothesis that maximum cardiac performance is linked to active metabolic rate (AMR) and critical swimming speed (U-crit). Six hundred juveniles (body mass similar to 150 g) were screened using a swimming challenge of 1.2 m s(-1) to identify 'poor swimmers' and 'good swimmers', i.e. the first and last 60 fish to fatigue, respectively. These 120 fish were individually tagged and then reared in common tanks for 9 months, where they grew at similar rates and achieved a similar body mass of approximately 1100 g. Critical swimming speed (U-crit) was then measured individually in tunnel respirometers, with simultaneous recordings of...

Adaptation of aquaculture system typologies to the requirements of sustainable development
Provedor de dados: 5
Autores: Lazard, Jerome; Baruthio, Aurele; Mathe, Syndhia; Rey-valette, Helene; Chia, Eduardo; Aubin, Joel; Clement, Olivier; Morissens, Pierre; Mikolasek, Olivier; Legendre, Marc; Levang, Patrice; Blancheton, Jean-paul; Rene, Francois.
The new sustainable development data repository requires new analysis grids, in particular for factors accounted for in productive system typologies. This paper, based on the aquaculture example, analyses the diversity in aquaculture systems with respect to sustainable development. Various typologies are obtained by evaluating structural and functional approaches integrating variables related to production and regulation systems and to the territorial insertion of fish farms. Categories have been defined on a scale based on a set of five sites, which are representative of a wider range of aquaculture systems. Use of these categories goes beyond the local typologies and prepares a generic meta-typology classification for the systems. This generic...

Comparison of two methods for evaluating waste of a flow through trout farm
Provedor de dados: 5
Autores: 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...

Towards environmentally sustainable aquaculture: Comparison between two trout farming systems using Life Cycle Assessment
Provedor de dados: 5
Autores: Roque D'Orbcastel, Emmanuelle; Blancheton, Jean-paul; Aubin, Joel.
Life Cycle Assessment(LCA) was applied to evaluate the global environmental impact of two scenarios of trout production systems based on the operational information from an operational farm using a flow through system (FFF) and an experimental pilot low head recirculating system (RSF) located on the same site. The main differences between the environmental balances of the two systems were relative to water use, eutrophication potential and energy use. Independently of the system used, feed is the key indicator in determining the environmental balance (notwithstanding eutrophication potential and water dependence) monitored by fish production, chemical products, buildings and energy consumption. Consequently, when considering the RSF with a lower feed...

Economic and Environmental Impacts of Improving Growth Rate and Feed Efficiency in Fish Farming Depend on Nitrogen and Density Limitation
Provedor de dados: 5
Autores: Besson, Mathieu; Komen, H; Vandeputte, Marc; Aubin, Joel; De Boer, I J M; Van Arendonk, J A M.
The aim of fish breeding is to increase profit by producing faster growing fish with lower feed intake. However, little is known about the economic and environmental impacts of selective breeding programs for fish. We modelled a fish farm producing African catfish in a Recirculating Aquaculture System (RAS) to calculate economic values of growth rate and feed efficiency with production limited by fish density in rearing tanks and fish nitrogen emission. We also calculated “environmental values” with Life Cycle Assessment. The economic and environmental values of growth rate and feed efficiency depended on the limiting factor. When nitrogen was the limiting factor, economic and environmental values of growth rate were zero. But, on the other hand, feed...

Trial of probiotics to prevent the vertebral column compression syndrome in rainbow trout (Oncorhynchus mykiss Walbaum)
Provedor de dados: 5
Autores: Aubin, Joel; Gatesoupe, Joel; Labbe, Laurent; Lebrun, Luc.
Two probiotics were tested as alternative treatment to limit the prevalence of the vertebral column compression syndrome (VCCS) in rainbow trout, compared with a preventive treatment with florfenicol. Either the antibiotic, or a lactic acid bacterium, Pediococcus acidilactici, or a yeast, Saccharomyces cerevisiae var. boulardii, was introduced into experimental diets, which were compared with the control diet without supplementation. The antibiotic caused some mortality during the first week after treatment, likely because of the toxicity of the compound. However, this antibiotic treatment limited the occurrence of VCCS to 3%, vs. 13% of fish affected in the control group. Pediococcus acidilactici provided the same level of protection as the antibiotic,...

Identification of relevant social impact indicators for a Social Life Cycle Assessment (SLCA) is still difficult and poorly documented (Jorgensen, et al, 2009). In aquaculture systems, the studies based on social aspects are essentially focused on manpower or on conflicts with other activities . In the PISCEnLit project**, we aim to broaden the vision of social impacts of fish farming systems using a new approach of SLCA. We studied fish farming pond systems in France (Lorraine and Brenne) and Indonesia (Tangkit Baru and Kumpeh Ulu in Sumatra island). In this study, we focused on the choice of the impact categories using the participation of stakeholders (James et al., 2002) by the identification and selection of the relevant social impacts to be assessed....

Scenarios of fish waste deposition at the sub-lagoon scale: a modelling approach for aquaculture zoning and site selection
Provedor de dados: 5
Autores: Chary, Killian; Callier, Myriam; Coves, Denis; Aubin, Joel; Simon, Julien; Fiandrino, Annie.
Spatial planning, including zoning and site-selection steps, is necessary to determine locations that minimize environmental impacts of aquaculture and respect ecosystem carrying capacities. This study aimed to analyse potential benthic waste deposition in a broad range of fish farming situations to facilitate zoning. To this end, we simulated waste dispersion for 54 aquaculture scenarios combining three red drum (Sciaenops ocellatus) farm types (Small, Medium, and Large) based on real farm characteristics and 36 sites with contrasting hydrodynamics in Mayotte’s North-East Lagoon. Key forcing variables and parameters of the particle-dispersion model for farms (layout and solid waste fluxes), species (feed- and faeces-settling velocities) and sites (depth...

Cultivating biomass locally or importing it? LCA of biomass provision scenarios for cleaner electricity production in a small tropical island
Provedor de dados: 5
Autores: Chary, Killian; Aubin, Joel; Guinde, Loic; Sierra, Jorge; Blazy, Jean-marc.
Biomass is a promising renewable alternative to decarbonize and to secure energy production on small islands, as most insular power generation systems rely heavily on imported fossil fuels. Feedstock procurement is a key aspect of bioenergy chain sustainability, and local resources as well as imported biomass can be considered if the electricity generated presents environmental benefits. We used Life Cycle Assessment (LCA) to evaluate the environmental impacts of 1 kWh of electricity produced in Guadeloupe from the combustion of locally grown energy cane and imported wood pellets. The energy cane agricultural supply was simulated using a bio-economic model to elaborate and analyze five scenarios involving different biomass mixes and geographical areas of...

Initiatives for the sustainable development of aquaculture have so far focused on the production of codes of conduct, of best management practices, of standards etc., most of which have been developed by international organisations, the industrial sector and non governmental organisations. They were, to a large extent, produced using a "top down" process and inspired by models from intensive industrial shrimp and sea fish farming (mainly salmon). However, most of global aquaculture production comes from small-and medium-sized farms, essentially in Asia which contributes 92% of the total world aquaculture production volume. The objective of this article is to define the contours of systemic typologies that are able to express the sustainability conditions...

Modeling sea cage outputs for data-scarce areas: application to red drum (Sciaenops ocellatus) aquaculture in Mayotte, Indian Ocean
Provedor de dados: 5
Autores: Chary, Killian; Fiandrino, Annie; Coves, Denis; Aubin, Joel; Falguiere, Jean-claude; Callier, Myriam.
Robust and accurate prediction of fish farm waste is a first and crucial step in managing the cause-effect chain that leads to local environmental impacts of aquaculture. Since aquatic production is diversifying with new fish species and extending to new areas for which data can be scarce, it is important to develop parsimonious approaches with fewer data requirements and less scientific complexity. We developed the Farm productIon and Nutrient emiSsions (FINS) model, which simulates fish farm operation and estimates fish biomass, feed inputs, and waste emissions from sea cages using simple modeling approaches and a variety of data sources. We applied FINS to red drum (Sciaenops ocellatus) culture in Mayotte by collecting relevant input data (growth,...
