Hatchery rearing of bivalve mollusks depends on the production of live micro-algae, which is costly and often unpredictable. Therefore, the development of a cost-effective artificial diet would greatly reduce the operating costs and improve the efficiency of bivalve seed production. This paper reviews the results reported so far in the literature on the use of the various alternatives to on-site algal production. Furthermore, an overview is presented of the results obtained by the authors using manipulated yeasts as algal substitutes in feeding trials with juveniles of various commercially important bivalve species. Literature data and experimental findings were compared with experience "from the field" through an international inquiry among the operators of 50 commercial and research hatcheries. Despite the extensive research efforts, artificial diets are rarely applied in the routine process of bivalve seed production and are mostly considered as a useful backup diet.
