ABSTRACT Food sources of three filter-feeding bivalves from two habitats (intertidal oyster Crassostreagigas, mussel Mytilus galloprovincialis, and subtidal cultured scallop Chlamys farreri) of Jiaozhou Bay (Qingdao, China) were determined by fatty acid and stable isotope analysis. Cultured scallop was characterized by significant diatom markers such as 16:1 / 16:0 close to 1 and high ratio of 20:5(n - 3)/22:6(n - 3), hence we assume that the scallop mainly feeds on diatoms. Fatty acid biomarkers specific to bacteria and terrestrial materials were also found in considerable amounts in scallop tissue, which suggested that there were substantial bacterial and terrestrial ...
