The objective of the present study was to assess the nutritional value of three diets containing commercial preserved  microalgae pastes and the relationship of their biochemical composition to the growth rate and fatty acids profile of juve-  nile Tapes philippinarum.  The feeding period was 6 weeks. At a daily ratio of 1% dry weight live weight of the clams–1, the trispecific diet with 40%  of I. galbana, 20% of T. suecicaand 40% of C. muelleri supported greater growth of animals than either a mixture of  80% of I. galbanaand 20% T. suecicaor I. galbanaalone (P  fied depending on the composition of the diets. In particular a decrease of EPA was observed in clams with the lowest  growth rate.
