Detailed explanation-1: -The most common negative environmental impacts that have been associated with aquaculture include: waters eutrophication, water quality, alteration or destruction of natural habitats; introduction and transmission of aquatic animal diseases (FAO, 2006a).
Detailed explanation-2: -ntroduction of exotic species has the extinction of native species in aquatic ecosystems. Major concerns over the introduction of exotic fish are prolific breeding, predation or competition of introduced species affecting indigenous biodiversity.
Detailed explanation-3: -Examples of such a situation include the Asian carp in the USA (Irons et al., 2007), suckermouth catfish in China (Gu et al., 2018a; Gu et al., 2018b), and Chinese mitten crab in Europe (Herborg et al., 2005).
Detailed explanation-4: -Invasive alien species generally reduce the abundance of native inland water species through predation, hybridization, parasitism or competition for resources (Olowo and Chapman, 1999) [55].
