The nutritional value, heavy metal content and lipid quality of five marine fishes from, Cameroon coast were be investigated. Fish samples from Ilisha africana, Sardinella, maderensis, , Arius parkii and Ethmalosa fimbriata were collected at, the Douala sea port, carried to the laboratory, washed with distilled water and, processed. Proximal composition, minerals, lipid quality and heavy metal analyses, were performed using AOAC standard methods. Results show that proteins (18.43%), and lipids (3.69%) contents were higher in Ilisha africana. had the, highest ash content (4.59%). Contents of minerals and heavy metals were found as, follows: P > Mg > K > Ca > Na > Fe > Zn > Cu > Mn and Hg > Pb > Cd > As. Oils extracted from , A. parkii and E. fimbriata were semi-siccative while those of I. africana and S. maderensis were siccative. Thus, these fish species are good sources of proteins and, minerals that can be used for managing mineral deficiencies in humans and animals.
对来自喀麦隆海岸的五种海鱼的营养价值、重金属含量和脂质质量进行了研究。从非洲伊丽沙鲱、马德拉小沙丁鱼、帕克氏海鲶和条纹遮目鱼采集的鱼样本在杜阿拉海港收集，带到实验室，用蒸馏水冲洗并进行处理。采用美国官方分析化学师协会（AOAC）的标准方法进行近端成分、矿物质、脂质质量和重金属分析。结果表明，非洲伊丽沙鲱的蛋白质（18.43%）和脂质（3.69%）含量较高。其灰分含量最高（4.59%）。矿物质和重金属含量如下：磷＞镁＞钾＞钙＞钠＞铁＞锌＞铜＞锰，汞＞铅＞镉＞砷。从帕克氏海鲶和条纹遮目鱼中提取的油是半干性的，而非洲伊丽沙鲱和马德拉小沙丁鱼的油是干性的。因此，这些鱼类是蛋白质和矿物质的良好来源，可用于解决人类和动物的矿物质缺乏问题。
