Description
Summary:The objective of this study was to investigate the effects of dietary phospholipids (PLs) on survival rate, growth performance and expression of key genes related with phosphatidylcholine (PC) metabolism in larval and juvenile large yellow croaker, Larimichthys crocea. Three isonitrogenous and isolipidic diets with graded levels of PLs (2.53%, 6.32% and 12.7%) were randomly allocated to triplicate groups of larvae (initial body weight: 3.86±0.24mg) eight times daily for 30days. Five isonitrogenous and isolipidic diets with graded levels of PLs (1.32%, 3.05%, 5.86%, 7.4% and 9.63%) were randomly allocated to triplicate groups of juveniles (initial body weight: 7.36±0.33g) twice daily to apparent satiation for 60days. Results showed that survival rate and specific growth rate of larvae fed the diet with 2.53% PLs were significantly lower compared with those of larvae in other groups (P
