| The present study investigated the possible use of emulsions as an artificial lipid supplement to live algae for seed of the Manila clam <i>Tapes philippinarum</i>. The uptake and assimilation of an emulsion, rich in docosahexaenoic acid (DHA, 22:6n-3) and eicosapentaenoic acid (EPA, 20:5n-3) and fed at concentrations of 20 and 40% of the algal dry weight, were verified analytically by fatty acid analysis of the animals and their diets. Dietary requirements for n-3 highly unsaturated fatty acids (HUFA) were examined by supplementing <i>Dunaliella tertiolecta</i>, which contains no polyunsaturated fatty acids longer than 18:3n-3 and <i>Tetraselmis suecica</i>, which contains EPA but only trace amounts of DHA. An algal... |

| Juvenile <i>Tapes philippinarum</i> (Adams and Reeve) were reared for three weeks on different rations of <i>Chaetoceros neogracile</i> which were either centrifuged and stored or fed together with the culture medium. Algal rations were adjusted daily in order to feed constant weight-specific daily rations. Growth of <i>T. philippinarum</i> fed the concentrate of <i>C. neogracile</i> was maximal at a daily ration of 1% (algal dry weight per clam live weight). <i>T. philippinarum</i> fed single or mixed diets of <i>C. neogracile</i> and <i>Isochrysis</i> sp. (clone T-Iso) directly from the algal cultures, maximized growth at a ration of 1,3% day <sup>-1</sup>.... |
