HORACIO, Trulls  e  MARIA LAURA, Ortiz. Major minerals and trace elements in fresh and sea water fish meat. Compend. cienc. vet [online]. 2022, vol.12, n.1, pp.32-42. ISSN 2226-1761.  https://doi.org/10.18004/compend.cienc.vet.2022.12.01.32.

Fish is a food of animal origin, considered a fundamental exponent of a healthy diet, with highly bioavailable nutrients, especially macrominerales and trace elements; very accessible for the population of poor and developing countries. The aim of this review was to evaluate the composition of major minerals and trace elements in fish meat of different species, both freshwater and seawater. A great variation was evidenced both in the contents of major and trace elements; according to the species, size and ecosystems studied. The mean values, expressed in mg/100 g of DM, were: Na: 147.5; K: 614.5; Ca: 653.2; Mg: 228.3; P: 288; and for microelements such as Fe: 3.25; Cu: 1.85; Zn: 4.33 and Mn: 12.6. It is concluded that small fish species, which are consumed with organs and skeleton, are excellent sources of minerals, constituting an alternative with a high contribution of micronutrients. Sustainable fishing and aquaculture are practices that should be promoted by public policies, especially in poor countries in Asia, Africa and Latin America.
