Sažetak
The conservation and active restoration of European flat oyster (Ostrea edulis)populations are a major focus of ecological restoration efforts to take advantageof the wide-ranging ecosystem functions and services this species provides.Accordingly, additional and new demands for seed oysters have arisen. In com- mercial aquaculture (mariculture), the production of O. edulis is still largelybased on natural seed collection. Considering the specific requirements, related toecological restoration, such as the absence of pathogens and the preservation ofhigh genetic diversity, the current supply is insufficient. Despite the developmentof breeding and controlled reproduction techniques for this species since the late1930s, seed production today is mainly based on empirical concepts. Several ofthe issues that producers still face are already subjects of research ; many othersare still unanswered or even unaddressed. This review provides a summary of allavailable knowledge and technologies of O. edulis seed production. Furthermore, it provides a detailed reflection on implications for restoration, future challenges, open questions and it identifies relevant research topics for sustainable seed sup-ply. The study covers the following aspects on (i) biology of the species, (ii) stres-sors – including pathogens and pollutants, (iii) genetics, (iv) history ofproduction technologies, (v) seed production in polls, (vi) seed production inponds and (vii) seed production in hatcheries. Future research needs on sex deter-minism, gametogenesis, cryopreservation, nutrition, selective breeding, pathogensand disease, and the development of reliable protocols for production are high-lighted.
