Déterminismes génétiques de l'allocation à la reproduction chez les huîtres creuses (Crassostrea gigas) triploïdes
Provedor de dados: 5
Autores: Normand, Julien.
In diploid Pacific oyster Crassostrea gigas, gonadic development can be important in terms of energetic investment. Phenotypic and genetic negative correlations have also been observed between gonadic occupation and traits related to survival and growth, and this fact suggests that this trait could be deleterious for its aquaculture production. Triploidy can be been artificially induced to improve the production of Pacific oysters as it results in a general diminution of mean gonadic development. This trait is however highly variable. In this context, this study aimed to quantify and qualify the allocation to reproduction in triploid oysters and to study its genetic bases. Variability for allocation to reproduction and growth was first studied in 3 sets of...
