| Dr. Boudry focussed his talk on oysters, which are the most important bivalve species produced world wide (more than 4 million tons). One of the main characteristic of bivalve aquaculture is that most of the juveniles ("seed or "spat") are collected from natural recruitment (e.g. 100% of the European mussel production). Hatchery propagation is used in the case of introduced species (e.g. Crassostrea gigas in USA) or limited natural recruitment. The most significant genetic improvement for the production of Pacific oyster (C. gigas) to date has been obtained through the breeding of triploids, especially since the development of tetraploids. Triploidy lead to highly reduced gametogenesis and, as a result better growth and survival. Many quantitative... |
