| Background Originating from Northeast Asia, the Pacific oyster Crassostrea gigas has been introduced into a large number of countries for aquaculture purpose. Following introduction, the Pacific oyster has turned into an invasive species in an increasing number of coastal areas, notably recently in Northern Europe. Methods To explore potential adaptation of reproductive traits in populations with different histories, we set up a common garden experiment based on the comparison of progenies from two populations of Pacific oyster sampled in France and Denmark and their hybrids. Sex ratio, condition index and microarray gene expression in gonads, were analyzed in each progeny (n = 60). Results A female-biased sex-ratio and a higher condition index were... |

| Originating from north-eastern Asia, the Pacific oyster Crassostrea gigas has been introduced, mainly for aquaculture purpose, into a large number of countries. Although highly variable, its invasive nature has been reported in an increasing number of coastal areas, notably. Northern Europe. We set up a common garden experiment based on the comparison of progenies of Pacific oysters sampled in France, where populations settled since the introduction of the species in the 70’s, and Denmark, where established populations were observed since the beginning of 90s. Pure and hybrid progenies, resulting from crosses within and between adults sampled in both populations, were studied for their sex-ratio, condition index, transcriptomics, and biochemical parameters |
