SUMMARY:

Tambaqui (Colossoma macropomum) is the main fish species produced in the Northern Region, and knowledge of its nutritional characteristics is essential for its proper use in human consumption. Therefore, the objective of this study was to evaluate the fatty acids in the meat of tambaquis slaughtered in different weight classes. Fifteen tambaquis were used, with the following treatments: (T1) between 1 and 1.5 kg; (T2) between 2 and 2.5 kg; and (T3) between 3 and 3.5 kg. After slaughter, the animals were placed in isothermal boxes with ice and transported to the laboratory. The fish were weighed to obtain the total weight and then each specimen was individually slaughtered. After processing, individual samples of meat from the trunks of the animals were obtained and fatty acid analysis was performed using gas chromatography. Subsequently, the profile, sum and ratio of fatty acids and meat indexes were obtained. A completely randomized experimental design was used and Pearson's test was used to analyze correlations. Slaughter weight influenced (P<0.05) the lipid profile of tambaqui meat fatty acids, with an increase in saturated (myristic and arachidic), monounsaturated (myristoleic, oleic and eicosenoic) and polyunsaturated (α-linolenic C18:3ω3 and C20:3ω3, eicosatrienoic and docosahexaenoic) fatty acids. In addition, the ω-6:ω-3 ratio was higher (P<0.05) for tambaquis slaughtered weighing 3.0 to 3.5 kg, confirming the quality of the meat from these animals. Thus, animals slaughtered between 3.0 and 3.5 kg had a better balance of fatty acids and, therefore, better meat quality.
