Abstract

Abstract

Fatty acid composition of the liver oils from common species of sharks and rays off southern and middle Fujian coastal waters is similar,and the major fatty acids include 16:0 (14.9%~23.7%),18:0 (5.3%~10.4%),18:1ω9(8.6%~16.9%),16:1(3.4%~7.5%),20:4 ω6(3.8%~14.7%) and 22:6ω3(10.7%~36.9%).The liver oils in allspecies are analyzed except Hypoprion sp.contains high levels of 22:6ω3(DHA),especially in Scoliodon sorrakowah.These species are therefore good sources of 22:6ω3 rich marine oils.The benthic species have a higher content of ω6 PUFA in liver oil than the pelagic species,while the contents of 22:6 ω3 and the ratios of ω3 PUFA to ω6 PUFA are relatively higher in pelagic species than in benthic ones.Fatty acid composition in the liver oils might be influenced by the feeding habit of animals.
