摘要

Possibility of Tetraselmis tetrathele utilization was tested as a basic food for swimming crab Portunus trituberculatus larval production, culturing the alga in NaHCO_3 enrichment medium. The algal density increased significantly by addition of NaHCO_3, when it was added at the same concentration as that of natural seawater. In crab larval culture, highest survival rate was 13 percent at early megalop larval stage. The possibility of larval rearing of this crab was observed with T. tetrathele as a basic food.
