The identification of novel feed materials as a source functional ingredients is topical priority in the finfish aquaculture sector. Due to agrotechnical practices associated and phytochemical profiling, halophytes emerge new feedstuff for aquafeeds, with potential boost productivity environmental sustainability. Therefore, present study aimed assess Salicornia ramosissima incorporation (2.5, 5, 10%), 2 months, diet juvenile European seabass, seeking antioxidant (in liver, gills, blood) genoprotective (DNA chromosomal integrity benefits. Halophyte inclusion showed no impairments on growth performance. Moreover, tissue-specific improvement was apparent, namely through GSH-related defense subsystem, but revealing multiple complex mechanisms. A genotoxic trigger (regarded pro-genoprotective mechanism) identified first month supplementation. clear protection DNA detected second month, all supplementation levels (and most prominent melioration at 10%). Overall, these results pointed out functionality S. ramosissima-supplemented diets promising way improve practices, also unraveling complementary novel, low-value raw material, path its valorization.
