| Oysters, like many other marine species, are characterized by very high fertilities. Natural or hatchery populations, often present very low Ne/N ratios (Hedgecock, 1994). It can be explained by very high variances of their breeding success (Li and Hedgecock, 1998), the effective population size being estimated through the temporal variance of the allelic frequencies in natural populations (Hedgecock et al., 1992) or, more directly, through the estimated number of founders in hatchery populations (Launey, 1998). This document is a presentation of the results of a number of experiments, realised in the scope of the European program "GENEPHYS" (FAIR 95-421), and using microsatellite markers to analyse the parental contributions in the flat oyster Crassostrea... |

| Numerous aquacultural species show very high fertilities. As a consequence, it is possible to produce, in hatcheries, a large amount of sibs from a small amount of parents. The sibs' genetic variability is, of course, directly linked to the number of parents involved, but it may be largely lowered by imbalanced parental contributions. Polymorphic genetic markers are very handy tools in the study of these phenomena in cultivated populations (Harris et al. 1991; Herbinger et al., 1996a; Garcia de Leon et al. 1998) or in natural populations (Ferguson et al, 1995; Kellog et al., 1995; Colbourne et al., 1996; Herbinger et al., 1996b). This document is a presentation of the results of a number of experiments, realised in the scope of the European program... |
