    ABSTRACT: 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.

    ABSTRACT: A study was undertaken to determine the effect of a high energy diet with two different protein levels on growth, feedefficiency and whole body composition of sharpsnout sea bream (Diplodus puntazzo). Two isoenergetic diets (24.1-24.7MJ Kg-1 dry weight) with two different protein levels (46.7 and 52.5% dry weight) were fed to satiety to duplicate groupsof 300 fish (initial body weight 27.7 ± 0.2 g) for 94 days. At the end of the experiment, the fish fed 52.5% protein showeda statistically higher (P Whole body composition was similar among treatments while the high energy level of the diets significantly modified lipidand moisture content in comparison with fish at the beginning of the experiment. Protein efficiency ratio (PER) and grossprotein efficiency (GPE) of fish fed 46.7% protein diet were statistically higher than those for the other diet. It may beconcluded that the diet with a lower protein level has given better protein utilization and a protein sparing effect but tendedto result in reduced weight gain and feed intake, when compared with diet containing higher protein levels.
