Abstract
In the current investigation we analyzed the gross biochemical, lipid class and fatty acid composition throughout different developmental stages (namely, egg, D-shaped larva, pediveliger larva and postlarva) of mussel Mytilus galloprovincialis. Lipid was the main biochemical fraction among egg reserves (counting ca. 80%), and the embryonic activities were fueled by stored triglycerides and esters. Polyunsaturated fatty acid (PUFA) 22:6n3 played a structural role during embryonic development, while monounsaturated fatty acids and other PUFA seemed to be preferentially catabolyzed (e.g. 20:5n3, 18:2n6 or 18:3n3). In the transition from D-shaped to pediveliger larva, all the biochemical fractions increased as nutrients were incorporated exogenously from diet. Non methylene interrupted dienoic fatty acid (NMID) levels were similar to those of some essential fatty acids during development. Lipid fraction increased in postlarvae with respect to pediveliger larvae, and no significant energy losses were detected with metamorphosis. Our results provide useful information for the successful hatchery production of M. galloprovincialis.
