Abstract Freshwater fish production depends on the production and use of polyunsaturated fatty acids (n‐3 and n‐6 PUFA) from lower trophic levels. Here, we aimed to identify the main trophic pathways that support PUFA content in different fish species (mean 39.7 mg/g dry weight) used in the subsiste...
