Lipid is one of the important nutrients for mollusks, especially at larval and juvenile stages, have
also been demonstrated (Delaunay et al., 1991; Marty et al., 1992; Robinson, 1992; Mai et al., 1995).
Lipid provides the source of energy, essential fatty acids (EFA) and other lipid classes like phospholipids
and sterols and fat-soluble vitamins (Watanabe, 1982). Knowledge of the protein sparing effects of
non-protein nutrients such as lipids or carbohydrates are necessary and should be used to reduce feed
costs and limit ammonia production (Vergara et al., 1999). Meanwhile, excessive energy in diets can
lead to decrease feed consumption (especially protein and other nutrients intake) and reduced growth
(Ellis and Reich, 1991). Lipid in mollusk larvae have been used as an index for monitoring their
physiological and nutritional status, and potential for successful metamorphosis (Gallager et al., 1986).
However, information on the quantitative requirement of dietary lipid and its utilization in mollusk is
mainly focus on the abalone. The optimal dietary lipid level of mollusk species, such as Haliotis discus
hannai （皱纹盘鲍） (Uki et al., 1985; Mai et al., 1995), Haliotis tuberculata (L) （欧洲疣鲍）(Mai
et al., 1995) had been demonstrated.
