| Summary: | Fish production by intensive aquaculture, is an economically important strategy to produce food. However, intensive sh farming generates oxidative stress and suppress the immune system, causing loss of product quality and increasing sh mortality rates. To diminish these effects, plants as a source of polyphenols with antioxidants and immunostimulant properties were administered to carnivorous farmed sh. The aim of this study was to describe the effects of plant polyphenols as antioxidants and immunostimulants on carnivorous sh, and to promote their use as functional ingredients in aquaculture. Plants as a source of polyphenols showed the ability to improve the immune and antioxidant defense systems of the analyzed species, resulting in a tissue of better nutritional quality and a higher endogenous antioxidant content. However, the biological properties of polyphenols are dependent on the type of plant and their concentration within it, the dose and the time of administration, as well as the food matrix, which determines their bioaccessibility and bioavailability in the organism. There is little information on the effec of polyphenols in post mortem quality; therefore, further studies should be conducted. |
