Article
Full-text available
In integrated multi-trophic aquaculture (IMTA), species from different trophic levels are raised in proximity to one another and the co-products (organic and inorganic wastes) of one cultured species are recycled to serve as nutritional inputs for others. IMTA can reduce the ecological impacts near aquaculture operations , improve social perception...
Article
A model for fish growth simulation based on the bioenergetic factorial approach is presented. This work presents a novel approach that extends the traditional bioenergetic model by explicitly including the Energy and Protein fluxes (EP model). This is a valuable feature that allows the dynamic simulation of fish proximate composition. For the aquac...
Presentation
The application of the extended bioenergetic model to simulate shrimp growth is presented. This generic modelling approach is based on the bioenergetic factorial approach and explicitly includes the energy and protein flows. As previously illustrated for the seabream following this approach it is possible to define a model that is species specific...
Presentation
Models designed to provide practical guidance about food limitation in oyster nurseries can support seed stock management. However, most of the available shellfish models are developed for adult oysters and seldom the target end-users of these models are farmers. The goal of this work is to present a nursery model application for seed stock managem...
Presentation
This work presents a simple nutrient mass balance model, developed for land-based seaweed farmers. The model provides the farmer, via a simple interface, the value of the water renewal rate that is necessary for a desired seaweed production, given a farm configuration and N input concentration in the inflow water. The model was calibrated and eva...
Article
Full-text available
Key factors affecting the economic sustainability of any aquaculture industry and in particular the seaweed industry are its ecological interactions and impacts. Understanding these issues requires an extended production analysis and simulation, given the natural variability and dynamics of external factors that affect those interdependencies. As s...
Article
This work aims to provide oyster farmers a tool to estimate the stock biomass to hold in their nursery. Herein, a steady-state single-compartment mass balance model, which includes the feeding activity of oyster spat, was developed. This model applies to nurseries such as floating upweller systems or land-based tanks and estimates (1) the optimal s...
Presentation
Optimization of aquaculture production systems is crucial to assure aquaculture sustainable growth. Farmers need to monitor the environmental conditions that affect fish production efficiency, disease outbreaks and waste production while assuring a real-time management of the entire process. A wide range of published models exist which help underst...

Managing combined sewage systems in large cities discharging to coastal waters, often bearing recreational activities, remains a challenge. Studying the impacts of such discharges requires the development of specific models. Hydrodynamic and water quality modelling of coastal waters employs numerical methods and algorithms, leading to the design of...
Article
Biochemical methane potential of four species of Ulva and Gracilaria genus was assessed in batch assays at mesophilic temperature. The results indicate a higher specific methane production (per volatile solids) for one of the Ulva sp. compared with other macroalgae and for tests running with 2.5% of total solids (196±9 L CH(4) kg(-1)VS). Considerin...

The rising share of aquaculture in supplying seafood changes the mixture of species in the world’s market, because capture fisheries target carnivorous species whereas aquaculture focuses on species that are lower in the food chain. Trophic level cor relates with production volume (tons =yr) and with unit value (US$ =ton) in aquaculture but not in...
Article
This article presents an approach that couples coastal ecosystem modeling with inte- grated environmental assessment methodologies to support coastal management. The focus is to support the development of an ecosystem approach to aquaculture man- agement including interactions with watershed substance loading. A Chinese bay, with intense aquacultur...

Anthropogenic activity has a negative impact on many coastal ecosystems, compromising the significant direct and indirect socio-economic benefits provided in these areas. Maintaining activities that depend on coastal zones while preserving the ecological state of the ecosystems represents a management challenge. Management of coastal zones requires...
Article
Integrated multi-trophic aquaculture (IMTA) possesses ecological and socio-economic advantages, relative to single-species aquaculture. The promotion of a sustainable aquaculture industry requires that decision-makers, ecosystem managers and farmers have sufficient quantitative information associated with its implementation from both public and pri...
Article
a b s t r a c t This paper presents a multilayered ecosystem modelling approach that combines the simulation of the biogeochemistry of a coastal ecosystem with the simulation of the main forcing functions, such as catchment loading and aquaculture activities. This approach was developed as a tool for sustainable management of coastal ecosystems. A...
Thesis
Full-text available
Over the past few decades, policy-makers have defined new instruments to address coastal ecosystem degradation. Emerging coastal management frameworks highlight the use of the best available knowledge about the ecosystem to manage coastal resources and maintain ecosystem’s services. Progress is required, however, in translating data into useful kno...
Article
This paper presents a Modeling Approach to Resource economics decision-maKing in EcoaquaculTure (MARKET model). The MARKET model was developed as a scenario-testing tool to provide insights on the ecological and economic interactions, which is a critical issue for sustainable aquaculture management. As a case study, the model was applied to simulat...
