RESUMO:

Farmed and captured fish is currently the most produced and consumed animal protein in the world and this demand will increase as a result of population growth and the search for healthier foods. Brazil has stood out worldwide in the production of food from aquaculture and the state of Rondônia is in 3rd place in the ranking of farmed fish production, being the largest producer of native fish in Brazil, with an emphasis on tambaqui (Colossoma macropomum). The production of native fish in the Amazon region is sustainable and has generated employment and income in local subsistence family fish farming and has increased local and global food security. Aiming to strengthen this production chain, the objective of this research is to conduct a bibliographic survey on the lipid composition of native Amazonian fish, analyze the benefits of consumption, as well as determine the lipid composition of commercial tambaqui (C. macropomum) cuts and for that this Master's Thesis is subdivided into two chapters in article format. The first chapter is a literature review on the lipid composition of native Amazonian fish and the second chapter is a research article entitled “Total omegas and lipid quality of commercial tambaqui cuts (Colossoma macropomum CUVIER, 1818) in a semi-intensive system in Rondônia, Western Amazon”. In both articles, it is evident that native fish contain monounsaturated (MUFA) and polyunsaturated (PUFA) fatty acids, which are related to an anti-inflammatory effect and a lower propensity for cardiovascular disease in consumers. The commercial cuts of tambaqui (C. macropomum), from 1.8 to 2.4 kg, presented PUFA in group ω-3 and ω-6 and MUFA in group ω-7 and ω-9. As for the lipid quality, the band was the cut that presented the highest balance between SFA and MUFA and the highest PUFA content; with Σ PUFA/ΣSFA index of (0.509), atherogenicity index (AI) (0.398), thrombogenicity index (TI) (0.797) and hypocholesterolemic to hypercholesterolemic fatty acid (HH) ratios (2.255). Next, the filet was the cut that presented the best results with a ΣPUFA /ΣSFA index of (0.391), AI (0.407), TI (0.958) and HH (2.160). The rib had a ΣPUFA /ΣSFA index of (0.364), AI (0.472), TI (1.087) and HH (1.858). The bid presented a ΣPUFA/ΣSFA index of (0.278), AI (0.726), TI (1.102) and HH (1.377). However, regarding the ΣPUFA index (ω-6/ω-3) the rib (5.296) presented a higher value than the filet (3.879), the band (3.173) and the steak (2.094). Therefore, the tambaqui (Colossoma macropomum) from Rondônia is sustainable and is an alternative in a healthy diet.
