Pleoticus muelleri is a species of commercial interest distributed in the Southwestern region of the Atlantic Ocean from Southern Brazil to Patagonia (23-50 °S). During the past two decades, it has shown an increase in ultraviolet radiation (UVR) and particularly the UVB (280-315nm) above Earth´s surface. While penaeoid shrimps are coastal species that inhabit generally at depths greater than 10 m, under cutivation conditions are kept in ponds at 2 meters deep, so they are exposed to extreme environmental conditions. It has been shown that many species of macroalgae synthesize and accumulate high concentrations of photoprotective compounds and may constitute an interesting alternative as a supplement in aquaculture feeds. The aim of this study was to determine the bioaccumulation of photoprotective compounds from a diet added with red seaweeds meal on juvenile P.muelleri and its possible protective effects under conditions of stress by ultraviolet radiation
