Boudry, Pierre / Collet, B / Mccombie, Helen / Ernande, Bruno / Morand, B / Heurtebise, Serge / Gerard, Andre - 2003In order to study individual growth variability and its relationship with survival in juvenile Crassostrea gigas, parental oysters were sampled at four sites located along the French Atlantic coast and bred under controlled hatchery conditions. Four groups of larvae were obtained by crossing five...Contributeur (s):

Taris, Nicolas / Sauvage, Christopher / Batista, Frederico / Baron, Sophie / Ernande, Bruno / Haffray, Pierrick / Boudry, Pierre - 2006Previous studies have shown heritable variation in larval developmental traits in the Pacific oyster Crassostrea gigas. In order to study the genetic consequences of production of oyster larvae in hatcheries, two factors, specific to hatcheries, were examined: the effect of discarding the smallest...Contributeur (s):

Taris, Nicolas / Ernande, Bruno / Mccombie, Helen / Boudry, Pierre - 2006The life histories of oysters in the genus Crassostrea, like those of most marine bivalves, are typified by high fecundity and low survival in nature. Rearing conditions in hatcheries however ensure optimized density, diet, and temperature. Hatcheries are becoming increasingly important for the...Contributeur (s):

Carpentier, Andre / Coppin, Franck / Dauvin, Jean-claude / Desroy, Nicolas / Dewarumez, Jean-marie / Eastwood, Paul D. / Ernande, Bruno / Harrop, Stuart / Kemp, Zarine / Koubbi, Philippe / Williams, Nigel Leader / Lefebvre, Alain / Lemoine, Michel / Loots, Christophe / S. Martin, Corinne / Meaden, Geoff J. / Ryan, Nick / Tan, Lei / Vaz, Sandrine / Walkey, Mike - 2005INTRODUCTION: The Dover Strait (Figure 1) connects the North Sea to the English Channel. Here, northern France and South-East England are at their closest. This narrow corridor, one of the world's busiest straits for maritime shipping, is a key economic area for numerous activities, such as...Contributeur (s):

Degremont, Lionel / Ernande, Bruno / Bedier, Edouard / Boudry, Pierre - 2007The multidisciplinary project "MOREST" aims to improve our understanding of causes of summer mortality in Crassostrea gigas juveniles in France and to reduce its impact on oyster production. As pail of the MOREST project, 43 full-sib families nested within 17 half-sib families were...Contributeur (s):

Boudry, Pierre / Degremont, Lionel / Taris, Nicolas / Mccombie, Helen / Haffray, Pierrick / Ernande, Bruno - 2004The most significant genetic improvement for production of Pacific oyster (Crassastrea gigas) has been obtained through the breeding of triploids, especially since the development of tetraploids. Quantitative genetics studies suggest that significant gains, for disease resistance or for other...Contributeur (s):

Ernande, Bruno / Boudry, Pierre / Heurtebise, Serge / Haure, Joel / Martin, Jean-louis - 2001Growth and survival are the two most interesting characters for oyster farming as they determine the biomass produced in the farms (growth x survival). Thus, a selection program aiming at improving these two characters could be of a great help. However, the oyster, as a sessile organism, is...Contributeur (s):

Hatchery techniques are now well handled in an increasing number of aquaculture species. However, unintentional effects of domestication often remain poorly documented. In this context, we studied how current hatchery practices may genetically influence larval traits for which significant genetic...Contributeur (s):

Taris, Nicolas / Sauvage, Christopher / Ernande, Bruno / Boudry, Pierre - 2005Among bivalve species, the Pacific oyster, Crassostrea gigas, is the most economically important bivalve production over the world. Today, C. gigas is subject to an important production effort that leads to an intensive artificial selection. Larval stage is relatively unknown, specifically in a...Contributeur (s):

Boudry, Pierre / Bedier, Edouard / Ernande, Bruno / Degremont, Lionel - 2006The multidisciplinary program "MOREST" aims to improve our understanding of causes of summer mortality in Crassostrea gigas juveniles in France and to reduce its impact on oyster production. As part of this program, four successive generations of families were bred between 2001 and 2005...Contributeur (s):

Boudry, Pierre / Degremont, Lionel / Bedier, Edouard / Pouvreau, Stephane / Normand, Julien / Ernande, Bruno - 2006To date, the most significant method to genetically reduce reproductive effort in the Pacific oyster (Crassostrea gigas) has been through the production of triploids, especially since the development of tetraploid lines allowing the breeding of 'natural' triploids. Gametogenesis of...Contributeur (s):

Ernande, Bruno / Haure, Joel / Degremont, Lionel / Bedier, Edouard / Boudry, Pierre - 2002Phenotypic and genetic correlations between fitness-related life-history traits - such as survival, growth and reproductive allocation - have to be considered to better understand selective processes, both in the wild and in breeding programs. Quantitative genetic experiments, based on nested half-...Contributeur (s):

Taris, Nicolas / Sauvage, Christopher / Ernande, Bruno / Boudry, Pierre - 2005Several studies have suggested that significant genetic variability might exist for some early developmental traits in the Pacific oyster, C. gigas. However, most studies have examined only limited numbers of families. More critically, these families were rarely replicated, leading to possible...Contributeur (s):
