“…Despite the gap in knowledge about the efficiency of these ARs for attracting species of commercial interest, previous studies in the region have suggested that the fish assemblages are affected by artificial structures, leading to increased abundance, species richness, and biomass over time, especially during the first six years after AR deployment (Zalmon et al, 2002;Brotto and Zalmon, 2008;Santos et al, 2011;Gatts et al, 2014;Santos and Zalmon, 2015). In addition, the attraction of invertebrates, retention of sediment, and seasonal inflows of freshwater and fluvial sediment may influence the temporal trends in fish assemblages associated with ARs (Rocha et al, 2014;Zalmon et al, 2014;Gatts et al, 2015;). Other studies have revealed that local fishermen regularly use ARs to capture specific target-species (Lima et al, 2018(Lima et al, , 2019b.…”
