A spatially explicit ecosystem model of seston depletion in dense mussel culture ArchiMer
Grant, J; Bacher, Cedric; Cranford, P; Guyondet, T; Carreau, M.
A fully-coupled biological-physical-chemical model of a coastal ecosystem was constructed to examine the impact of suspended mussel culture on phytoplankton biomass in Tracadie Bay, Prince Edward Island, Canada. Due to the extent of mussel culture there, we hypothesised that shellfish filtration would control the concentration and distribution of phytoplankton and other suspended particles in the bay. Circulation was delineated with a tidally-driven 2D numerical model and used to drive an ecosystem model with a focus on pelagic components including phytoplankton production, nutrients, detritus, and mussels. The benthos were treated as a sink. Nutrients and seston were forced by tidal exchange and river input, with phytoplankton additionally forced by...

Available Benthic Energy Coefficient (ABEC): a generic tool to estimate the food profitability in coastal fish nurseries ArchiMer
Tableau, Adrien; Le Bris, H.; Brind'Amour, Anik.
The benthic production of prey seems to be one of the main drivers among many environmental factors that influence the quality of fish nurseries and potentially limit their carrying capacity. However, the contribution of food availability in the growth and survival of juveniles is still controversial. The Available Benthic Energy Coefficient (ABEC) aims to assess the trophic profitability of benthic invertebrate prey; this concept reflects the combination of energy richness and availability of prey. A value of the coefficient was associated with each prey species. This value was calculated from the product of 4 components: (1) mass energy, (2) productivity, (3) regeneration, and (4) accessibility. Thus, this coefficient is expressed as a quantity of energy...

Climate Change Influences Carrying Capacity in a Coastal Embayment Dedicated to Shellfish Aquaculture ArchiMer
Guyondet, T.; Comeau, L. A.; Bacher, Cedric; Grant, J.; Rosland, R.; Sonier, R.; Filgueira, R..
A spatially explicit coupled hydrodynamic-biogeochemical model was developed to study a coastal ecosystem under the combined effects of mussel aquaculture, nutrient loading and climate change. The model was applied to St Peter's Bay (SPB), Prince Edward Island, Eastern Canada. Approximately 40 % of the SPB area is dedicated to mussel (Mytilus edulis) longline culture. Results indicate that the two main food sources for mussels, phytoplankton and organic detritus, are most depleted in the central part of the embayment. Results also suggest that the system is near its ultimate capacity, a state where the energy cycle is restricted to nitrogen-phytoplankton-detritus-mussels with few resources left to be transferred to higher trophic levels. Annually, mussel...

Ecophysiological model of growth and reproduction of the black pearl oyster, Pinctada margaritifera: potential applications for pearl farming in French Polynesia ArchiMer
Pouvreau, Stephane; Bacher, Cedric; Heral, Maurice.
A model of bioenergetics of the black pearl oyster (Pinctada margaritifera) was built to simulate growth, reproduction and spawning in suspended culture at field sites in Takapoto lagoon (French Polynesia). This model was based on allometric scaling of physiological functions and scope for growth (SFG) calculations. The input functions were clearance rate (CR, 1 day(-1)), retention efficiency (RE, %) for each kind of particle encountered in suspended matter, pseudofaeces and faeces productions (PF and F, mg C day(-1)), excretion and respiration rate (U and R, mg C day(-1)). The assimilated carbon (i.e., SFG, mg C day(-1)) was partitioned to the three internal state variables (somatic tissue, shell and gonad) according to the asymptotic increase of the...

Effects of blue shrimp Litopenaeus stylirostris and goldlined rabbitfish Siganus lineatus in mono- and polyculture on production and environmental conditions ArchiMer
Trung Cong, Luong; Lemonnier, Hugues; Hochard, Sebastien; Royer, Florence; Letourneur, Yves.
This study was conducted to compare the effects of shrimp and rabbitfish in mono- and polyculture stocked at high biomass on production and environmental conditions in a mesocosm system. Shrimp (14 g) and/or rabbitfish (19 g) were stocked in four treatments with different density but with the same total biomass (236 g m−2), including shrimp monoculture (SM) (17 shrimp m−2), shrimp–fish polyculture (SF) (11 shrimp and 4 rabbitfish m−2), fish–shrimp polyculture (FS) (6 shrimp and 8 rabbitfish m−2) and fish monoculture (FM) (12 rabbitfish m−2). After 10 weeks of experiment, shrimp survival and biomass were low in the treatments where shrimp were dominant (SM, SF), while rabbitfish survival and biomass were high in all the treatments. Shrimp mortality was...

Etude et modélisation des mécanismes impliqués dans la croissance de l'huître perlière, Pinctada margaritifera, au sein de l'écosystème conchylicole du lagon de l'atoll de Takapoto (Polynésie Française) ArchiMer
Pouvreau, Stephane.
L'huître perlière, Pinctada margaritifera (Linné, 1758) var. cumingi (Reeve), productrice de perles noires, fait l' objet d'une aquaculture florissante en Polynésie Française. Afin de pérenniser cette activité, un programme de recherche (le PGRN) a été lancé, en 1990, sur l' atoll de Takapoto. L' un des thèmes de ce programme réside dans l'étude de la capacité trophique d'un lagon soumis à une activité de perliculture. A cet égard, un modèle déterministe expliquant la croissance et la reproduction de P. margaritifera à partir des paramètres du milieu (notamment la nourriture disponible) a été mis au point. La construction de ce modèle a impliqué : ( 1) l'analyse de l'hydrobiologie du lagon; (2) l'étude de la physiologie de P. margaritifera; (3) le sui vi...

Evaluation of the carrying capacity of molluscan shellfish ecosystems ArchiMer
Heral, Maurice.
Growth of molluscs raised in coastal zones, where the water exchange rate is low, appears to be limited, once a certain biomass level is attained, by the availability of food, making it necessary to determine as accurately as possible the trophic capacity of an ecosystem. This paper analyses the various sources of food for molluscs. It would appear that dissolved organic substances play a major role, providing up to half the energy necessary for their metabolism. Particulate material is filtered by molluscs in proportion to their size, with optimum filtration rates varying with species. The negative effect on meat production of high mineraI seston rates is demonstrated, and an analysis provided of the respective role of each component of organic matter....

Grazing management strategies for massaigrass-forage peanut pastures. 3. Definition of sward targets and carrying capacity. Repositório Alice
ANDRADE, C. M. S. de; GARCIA, R.; VALENTIM, J. F.; PEREIRA, O. G..
This study was carried out to define sward management targets for mixed Massaigrass (Panicum maximum x P. infestum, cv. Massai) and forage peanut (Arachis pintoi Ac 01) pastures in the Western Brazilian Amazon. Seasonal variation in the pasture carrying capacity was also analyzed. Pastures were intermittently stocked at three daily herbage allowance levels (9.0, 14.5 and 18.4% of live weight) from October 2002 to December 2003. Sward targets were defined in terms of the sward condition that best conciliated the grass-legume balance, the maintenance of the structure of Massaigrass tussocks and the equilibrium between forage production and utilization. For the Western Brazilian Amazon conditions, the following sward management targets can be recommended for...

Influence of planktonic foodweb structure on a system's capacity to support pelagic production: an inverse analysis approach ArchiMer
Marquis, Elise; Niquil, Nathalie; Vezina, Alain F.; Petitgas, Pierre; Dupuy, Christine.
Coupled plankton/small pelagic (SP) fish systems were analysed to assess how foodweb structure influences the export of carbon to pelagic fish during the spring bloom in the Bay of Biscay. The investigation of carbon export flows through inverse analysis was supplemented by estimating the carrying capacity for pelagic fish production by applying linear programming. A planktonic foodweb dominated by microbial pathways had the highest trophic efficiency owing to the tight coupling between planktonic trophic levels and predation pressure on mesozooplankton by fish. Moreover, the magnitude of the gap between carrying capacity and estimated carbon export was related to the size structure of primary producers, with the picophytoplankton-based foodweb having the...

Influence of shellfish farming activities on the biogeochemical composition of the water column in Thau lagoon ArchiMer
Souchu, Philippe; Vaquer A, André; Collos, Yves; Landrein, Sonia; Deslous-paoli, Jean-marc; Bibent, Bertrand.
Thau lagoon is a Mediterranean shellfish ecosystem with large biomasses of oysters growing in waters with high residence time due to low tidal ranges, The influence of filter feeders (oysters and their epibiota) on the spatial distribution of particulate and dissolved compounds in the water column of Thau lagoon was studied through its variation with time, In 1991/1992, daily variations were investigated in pens, corridors and outside shellfish farming zones for nutrients, chlorophyll a and primary production. Salinity, dissolved oxygen, nutrients, organic matter and chlorophyll a were also monitored in surface waters inside and outside shellfish farming zones each week from January 1993 to March 1994. The presence of shellfish farms led to a decrease by...

Informing Marine Spatial Planning (MSP) with numerical modelling: A case-study on shellfish aquaculture in Malpeque Bay (Eastern Canada) ArchiMer
Filgueira, Ramon; Guyondet, Thomas; Bacher, Cedric; Comeau, Luc A..
A moratorium on further bivalve leasing was established in 1999–2000 in Prince Edward Island (Canada). Recently, a marine spatial planning process was initiated explore potential mussel culture expansion in Malpeque Bay. This study focuses on the effects of a projected expansion scenario on productivity of existing leases and available suspended food resources. The aim is to provide a robust scientific assessment using available datasets and three modelling approaches ranging in complexity: (1) a connectivity analysis among culture areas; (2) a scenario analysis of organic seston dynamics based on a simplified biogeochemical model; and (3) a scenario analysis of phytoplankton dynamics based on an ecosystem model. These complementary approaches suggest (1)...

Particulate matter in Takapoto lagoon waters: potential food for cultivated pearl oysters ArchiMer
Buestel, Dominique; Pouvreau, Stephane.
Results of research concerning the food of the pearl oyster Pinctada mai margaritifera are presented, by taking Takapoto atoll (Tuamotu archipelago, French Polynesia) as a study site. Monthly sampling of several parameters representative of bivalve environment and food (water temperature, salinity, mineral and organic matter, proteins, lipids and carbohydrates, chlorophyll a and phaeopigments) confirm and increase knowledge of the Takapoto lagoon hydrobiology. The variability of these parameters was analysed. Takapoto lagoon showed a remarkable spatial stability. Temporal variations showed a low seasonal trend. Local meteorology (wind, precipitation) had an influence on short-term variability (especially for mineral matter). Night and day rhythm also...

Performance of triploid Pacific oysters Crassostrea gigas (Thunberg) reared in high carrying capacity ecosystem : survival, growth and proximate biochemical composition ArchiMer
Goulletquer, Philippe; Joly, Jean-pierre; Gerard, Andre; Le Gagneur, Eric; Moriceau, Jacques; Peignon, Jean-marie; Heurtebise, Serge; Phelipot, Pascal.
Triploid oysters Crassllstrea gigas were: produced in 1990 by treating fertilized eggs with cytochalasin B (CS). Triploids, treated diploids, and controls were deployed early 1991 in a high carrying capacity ecosystem on the Eastern Coast of Normandy (France). A monthly monitoring in 1992 showed that triploids yielded significantly higher growth rate and biochemical composition. However, growth was more heterogeneous. No evidence was found for a length or weight bimodal frequency distribution within triploid groups after a 26 months rearing cycle. Triploids showed retardation of gametogenesis. Carbohydrates content in triploids remained almost constant (40%) from June to September. Their survival rates were significantly lower than controls. Moreover...

A study of pearl oysters Pinctada margaritifera growth and mortality was done on a monthly basis between June 1990 and September 1991 in Takapoto atoll (Tuamotu archipelago). Meanwhile, sampling parameters representative of bivalves food showed a remarquable spatial stability whithin the lagoon. The amplitude of temporal variability varied in the order of some days. Carrying capacity appears low : energetic content of particulate material in waters is about 2 joules/liter, ten times lower than in temperate areas. On the opposite, seasonal effect is reduced and particulate food is always available. Oysters rearing conditions were appropriate during the studied period with a low mortality rate and a regular growth in size (from 97 mm to 136 mm). Pearls...

Mar Piccolo of Taranto is an estuarine basin heavily exploited for commercial mussel (Mytilus galloprovincialis L.) farming. The historical renown of the Taranto mussels has suffered over the last decade following policy decisions to expand the mussel farms and to relocate a portion of the urban sewage to an outfall outside of Mar Piccolo. The resulting decline in mussel quality and the quandary of how to restore stability to Taranto mussel production became the focal issue for our application of the systems approach framework (SAF). We simulated the ecological, economic, and social interactions that affect mussel production. Stakeholders and mussel farmers contributed by participating in meetings during the entire exercise. Our simulation analysis...
