Abstract

|
|
|
The lipid components of cultured bastard(Paralichthys olivaceus) were analyzed and compared with those of wild one and flounder(Pleuronichthys cornrctus). Total lipid(TL) content of dorsal muscle in wild and cultured bastard, flounder was 2.0%, 1.6%, and 1.9%, respectively. Wild bastard and flounder were higher in neutral lipid(NL) and glycolipid(GL) contents, while lower in phospholipid(PL) content than those of cultured one. The NL was mainly consisted of triglyceride(70.7-72.6%), and PL was mainly occupied by phosphatidylcholine(53.6-58.3%), phosphatidylethanolamine(25.9-29.5%). In fatty acid composition of TL, cultured bastard showed higher content in polyenes such as docosahexaenoic acid, and lower in monoenes such as palmitoleic, oleic acid than those of wild one. Flounder was higher in percentage of arachidonic, eicosapentaenoic acid compard with bastard. The major fatty acids of these fishes were palmitic, docosahexaenoic, oleic, eicosapentaenoic and palmitoleic acid in order. These fatty acid composition of NL, GL and PL fractions were not significantly different among wild and cultured bastard, flounder.
