Outline of Final Research Achievements

The annual catch of the Manila clam Ruditapes philippinarum in coastal waters continues to decrease drastically. Thus, the conservation of the clam resource and a stable market supply depend on the development of a mass culture method for the clam. In this study, we examined the effects of alginate-hydrolysates (AHs) as a diet of juvenile Manila clams, and verify the role of AHs on the growth promotion of R. philippinarum. Our results indicate that supplementing a diet of Nannochloropsis oculata and/or Eutreptiella sp. with AHs can promote the growth of R. philippinarum. In addition, analysis of bacterial flora suggested that rearing conditions affected bacterial flora in digestive canal of clams. Thus, rearing clams on an algal diet supplemented with AHs may be an inexpensive way to shorten the rearing period of the juvenile clams and other bivalves, although we have not yet identified the underlying mechanisms behind these effects.
