Abstract. One of the most consumed fish in the world is Silurid, also called "leather fish" or catfish, whose main characteristic is the absence of intramuscular bones and scales, as well as its high productivity. In recent years, the nutritional characterization of the meat of some of these species has been carried out, finding that, although the proximal composition is within the broad ranges for fish, the fat content provides a lower proportion of polyunsaturated fatty acids (PUFA) particularly as regards omega-3 (w-3), furthermore the w-6/w-3 ratio is within the proscriptions of the World Health Organization (WHO) for many of these species of catfish. Likewise, the contents of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and amino acids, minerals and vitamins reveal a high variability between individuals and species associated with the type of cultivation and dietary habits and also with the age and weight at slaughter. Furthermore quality parameters have been defined in relation to susceptibility to autolysis, oxidation and hydrolysis of fats and disturbances caused by microorganisms that cause decisive changes in the physicochemical, microbiological and sensory characteristics. This review compiles current information regarding the nutritional composition of catfish meat and the quality parameters.
