A single bio-energetics growth and reproduction model for the oyster Crassostrea gigas in six Atlantic ecosystems

Abstract

Many studies based on bioenergetics growth models have investigated the effects of environmental factors on oyster (Crassostrea gigas) growth and physiology. However, most of these models are site-specific and cannot be app lied to other culture sites without the re-estimation of parameters or re-formulation of some processes. We aimed to develop a gen eric growth model suitable for application in contrasting environments, with a constant set of parameters. We tested the oyster-DEB model (Bourlès et al. 2009) for the stimulation of C. gigas growth in different cohorts (spats and adults) at major shellfish culture sites in

Several authors have dynamically coupled DEB models with biogeochemical models to provide feedbacks from aquaculture farms to phytoplankton and nutrient dynamics.…”

Remote sensing of suspended particulate matter in turbid oyster‐farming ecosystems

“…Maps of satellite‐derived SST, Chl‐ a , and SPM concentration could therefore be used to map oyster growth in oyster‐farming areas. Several ecophysiological models including the Dynamical Energy Budgets (DEB) and the Scope for Growth (SFG) have been successfully used to simulate oyster growth in several oyster‐farming areas along the French coast [ Alunno‐Bruscia et al ., ] including Bourgneuf Bay [ Barillé et al ., ]. The modeling approach is not restricted to oyster‐farming, and could be extended to other shellfish species, such as cockles [ Troost et al ., ], mussels [ Rosland et al ., ], or scallops [ Bacher et al ., ].…”

Disruption of amylase genes by RNA interference affects reproduction in the Pacific oyster Crassostrea gigas

“…Energy budget models can help in this respect by describing physiological processes linked with the energetics of marine bivalves in response to environmental fluctuations (see Alunno-Bruscia et al, 2011 for a summary). Among the energetic models developed and used for bivalves, dynamic energy budget (DEB) models have provided rates at which organisms assimilate and use energy for maintenance, growth and reproduction (e.g.…”

“…Among the energetic models developed and used for bivalves, dynamic energy budget (DEB) models have provided rates at which organisms assimilate and use energy for maintenance, growth and reproduction (e.g. Pouvreau et al, 2006;Alunno-Bruscia et al, 2011). The recently improved version of the DEB model for C. gigas focused on the description of reproduction-related features and permitted a description of energy allocation to the gametogenesis and resorption processes (Bernard et al, 2011).…”
