Resumo: One of the benefits associated with the consumption of fishery products is their fatty acid composition. In this dissertation we analyze the fatty acids profile of Atlantic ditch shrimp Palaemonetes varians, determined by gas chromatography. For this, 16 samples were collected in the Sado estuary area and examined. This study identified the majority of the P. varians fatty acids. In terms of highest quantity, we had the palmitic acid in SFA group, the oleic acid in MUFA and finally EPA in PUFA. Higher n-3/n-6 and PUFA/SFA ratios were also noticed. Related outcomes were found in studies associated to several other species of crustaceans. In July, the P. varians exhibited lower levels of MUFA, higher SFA values and higher n-3/n-6 ratio in comparison with the values registered in November (p<0,001). Comparing adult and juvenile P. varians, and despite not having significant variations in PUFA, it is noted the higher concentration of MUFA and lower SFA in adults (p<0,05). Few significant differences were observed between wild and not wild P. varians. A higher concentration of palmitic acid was found in not wild P. varians.These differences may be explained mainly by the food ingested by P. varians.
