Description
Summary:A selective breeding program with the European Oyster Ostrea edulis L. has been in progress at Dalhousie University since 1977. First generation selected lines were produced in 1977 and 1978. The selected parents came from the 1975 hatchery year class which were offspring of the original imports to Nova Scotia, considered here as the parental oysters. In both years, the parental oysters were respawned as control lines. Oysters from all lines, individually labelled within a few months of spawning, were stocked in lantern nets and grown in the field. Up to this time selection has been for growth rate only. The analysis of these lines will show the progress made in the early stages of this selective breeding program.
