The aim of this research was to quantify the methyl esters of linoleic (LA), α‐linolenic (LNA), arachidonic (AA), eicosapentaenoic (EPA), and docosahexaenoic (DHA) acids in the muscular tissue and orbital cavity of farmed Matrinxã ( Brycon cephalus ) and in those caught in the Brazilian Amazonian Area during two periods. For the farmed fish, the amounts (mg/g of fat) of LA, LNA, AA, EPA, and DHA found in the muscle were 197.6, 75.7, 165.0, 4.1, and 30.0 mg/g of fat, respectively. The amounts of these FA in the orbital cavity were 152.6, 9.1, 249.4, 3.6, and 22.3 mg/g of fat for LA, LNA, AA, EPA, and DHA, respectively. For the fish caught during the wet period, the LA, LNA, AA, EPA, and DHA found in the muscle were 438.2, 118.3, 42.7, 5.2, and 10.3 mg/g of fat, in the orbital cavity were found 489.1, 18.6, 18.1, 6.2, and 18.7 mg/g of fat, respectively. In the dry season, the amounts (mg/g of fat) of LA, LNA, AA, EPA, and DHA in the muscle were 193.1, 40.0, 43.4, 8.1, and 61.3, while the found in the orbital cavity were 152.9, 28.4, 5.1, 4.9, 19.6 mg/g of fat. According to their contents of EPA, and DHA, matrinxã captured in the dry season can be considered as a rich source of EFA.
