Seasonal Variations in Lipid Content, Fatty Acid Composition and Nutritional Profiles of Five Freshwater Fish from the Amazon Basin

Fish from the Amazon Basin are affected by oscillations in the river water volume, which influences the diet of animal species. This study was aimed at evaluating seasonal variations in lipid content, fatty acid composition and nutritional profiles of five fish species from the Amazon Basin. The lip...

Description
Summary:Fish from the Amazon Basin are affected by oscillations in the river water volume, which influences the diet of animal species. This study was aimed at evaluating seasonal variations in lipid content, fatty acid composition and nutritional profiles of five fish species from the Amazon Basin. The lipid contents of all fish species were observed to be lower in flood periods than in drought periods; Brachyplatystoma flavicans showed the largest variation (6.75–15.43 %) between these periods, while Colossoma macropomum showed no significant difference ( p  > 0.05). The fatty acid composition in the five fish species varied throughout seasonal periods; saturated fatty acid (SFA) contents decreased in flood periods, whereas polyunsaturated fatty acid (PUFA) contents significantly ( p
