Effect Of Artificial Diets Containing Carotenoid-Rich Microalgae On Gonad Growth And Colour In The Sea Urchin Psammechinus Miliaris (Gmelin).
Gonadal growth and color were examined in the echinoid Psammechinus miliaris when fed diets containing either micro- or macroalgal supplements. Urchins receiving diets containing the microalgae Phaeodactylum tricornutum and Tahitian Isochrysis sp. showed significantly greater gonad growth at the end...
