Although the detrimental ecological and economic effects of introducing freshwater fish species have been extensively documented, non-native fishes continue to be introduced in large numbers globally enhance fisheries aquaculture. In Turkey, stocking common carp Cyprinus carpio is practised provide food security for people job artisanal fishers, resulting a country-wide distribution. These stockings, however, increase risk accidental introductions led subsequent invasions gibel Carassius gibelio, invasive highly species. Here, we assessed growth types, body conditions trophic interactions via bulk carbon nitrogen stable isotope analysis both natural artificial water bodies Turkey. The results indicated that express similar types all waters ecologies. This leads substantial niche overlaps where they co-occur, with potential strong interspecific competition. Considering ongoing fishery enhancement, recommend specifically target these stockings has already become invasive. Our findings, indeed, suggest releases hamper populations by increasing competitive between two
