| Abstract |
Hatchery rearing of bivalve mollusks depends on the production of live micro-algae, which is costly and often unpredictable, and 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 literature on the use of various alternatives to on-site algal production, plus the results obtained by the authors using manipulated yeasts as algal substitutes in feeding trials with juveniles of various commercially important bivalve species, and compares this information with experience "from the field" obtained through an international survey of operators of 50 commercial and research hatcheries. Despite the extensive research efforts, it appears that artificial diets are rarely applied in the routine production of bivalve seed and are mostly considered a useful backup diet. |
