The viscera of 10 kinds of marine fishes were collected for fish oil extraction and detection of DHA and EPA, two most important polyunsaturated fatty acids. The fish oil extraction ratio for the evaluated fishes varied from 0.95% to 10.18% (wt%). Pseudosciaena crocea presented the highest fish oil yield, followed by Mustelus manazo, Hippoglossus and Sciaenopsocellatus. A gas chromatography method was then established for analysis of EPA/DHA. The EPA concentration (in methyl ester form) in the fish oil varied from 1.39 to 10.65(mg/g). Epinephelus awoara presented the highest EPA concentration (p<0.05), followed by Epinephelussp, Sciaenopsocellatus and Hippoglossus. The DHA concentration (in methyl ester form) in the fish oil varied from 0.58 to 37.02 (mg/g). Epinephelus awoara presented the highest DHA concentration (p<0.05), followed by Sciaenopsocellatus, Pseudosciaena crocea and Hippoglossus. No strict positive correlation between the EPA/DHA concentration and the sea depth where the fish live was observed. The fishes living in middle depth presented highest EPA/DHA concentration.
收集了10种海鱼的内脏用于提取鱼油，并检测两种最重要的多不饱和脂肪酸DHA和EPA。所评估鱼类的鱼油提取率在0.95%至10.18%（重量）之间变化。大黄鱼的鱼油产量最高，其次是星鲨、大西洋庸鲽和美国红鱼。然后建立了一种气相色谱法用于分析EPA/DHA。鱼油中EPA的浓度（甲酯形式）在1.39至10.65（mg/g）之间变化。青石斑鱼的EPA浓度最高（p<0.05），其次是石斑鱼属、美国红鱼和大西洋庸鲽。鱼油中DHA的浓度（甲酯形式）在0.58至37.02（mg/g）之间变化。青石斑鱼的DHA浓度最高（p<0.05），其次是美国红鱼、大黄鱼和大西洋庸鲽。未观察到EPA/DHA浓度与鱼生活的海深之间存在严格的正相关关系。生活在中等深度的鱼类呈现出最高的EPA/DHA浓度。
