Note
Food values of eurytopic microalgae obtained from Solar Energy Research institute were examined by measuring larval development and growth of the bivalve species Crassostrea virginica (American oyster), Cyrtopleura costata (angel wing clam) and Mercenaria mercenaria (hard clam). Unialgal batch cultures of microalgae Ellipsoidon sp. (strain Ellipl), Nannochloris sp. (strain Nanno2), Chaetoceros muelleri Lemmermann (strain Chaet14) and Isochrysis aff. galbana Green (strain T-Iso) were grown using 30 ppt salinity ocean water enriched with f/2 medium, silicate and urea. Larval feeding experiments were conducted in 25 ppt salinity water. Shell length (growth) varied depending on the type of diet offered to the larvae.
