“…The ecological function of artificial reservoirs is important from a social perspective, providing recreational ecosystem services of which angling is particularly common in industrial, urbanised and densely populated areas (Arlinghaus, Mehner, & Cowx, ; Rzętała, ). However, recreational fishing can have significant impacts on aquatic ecosystems, depending on the degree of pressure, the fish stocking structure and the ichthyofauna species composition (Amaral, Franco, & Ferreira, ; Cooke & Schramm, ; Cowx & Gerdeaux, ). For example, the catch of non‐predatory fishes often involves the use of ground baits, which consist of organic component mixtures that are a nutrient source and, to a certain limit, can be effective in increasing the carrying capacity of the fishery and the catch of cyprinid fish.…”
