Seasonal variations in total fatty acid compositions of tucunaré, Cichla sp. in the Janauacá Lake of the Amazon basin were determined by GC. Saturated fatty acids (SFAs) were found to be at higher concentrations than monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs) in two seasonal periods. Major fatty acids were palmitic (16:0, 48.5–51.6% of total SFA), oleic (18:1ω9, 43...
The levels of the fatty acids EPA and DHA were determined for two species of fish (Hypophthalmus sp. and Cichla sp.), in the muscular tissue and in the orbital cavity, in two different seasonal periods in the Brazilian Amazonian area. Relatively high amounts (oil mg/g) for freshwater fish were found for DHA in the two species. Hypophthalmus sp. presented a higher concentration of EPA (20±3mg/g) and...
