Phytoplankton in the surface layers of South China Sea, Western Philippines were investigated for species composition, distribution and abundance. Thirty one stations were sampled during the cruise of M/V SEAFDEC to South China Sea along latitudes 8° to 20°N and longitudes 115° to 121°E from April 15 to May 11,1998. In each station, water samples at the surface and at depths of 20, 40 and 60-m ...

Continuous cultures of Chaetoceros muelleri, Skeletonema costatum and Rhinomonas reticulata of controlled biochemical compositions were fed to Mytilus edulis larvae over a 2-week period and the larval growth was assessed. The eggs as well as the larvae which subsequently developed were analyzed for their relative fatty acid profile and content; 27 fatty acids were identified by means of GCrMS. ...

Through biological flume experiments, we studied the effect of shear velocity and attachment period on the percent detachment of Pecten maximus post-larvae of different sizes reared on two experimental diets. The first diet, (Pavlova lutheri, Isochrysis galbana, Chaetoceros calcitrans), which served as a reference diet (PTC), is commonly used in bivalve hatcheries; the second is the PTC diet wi...
