“…Fortemente associada ao turismo, a pesca desportiva, bem como iniciativas de peixamento de reservatórios, açudes e represas de hidrelétricas, têm sido, por décadas, uma das principais vias de introdução e dispersão de espécies exóticas no país, frequentemente ignoradas em razão de sua popularidade e relevância econômica (Saul 2017, Turbelin 2022, Casimiro et al 2022). Aplica-se, entretanto, praticamente o mesmo arcabouço legal utilizado na aquicultura.…”

“…The first stock enhancement program by breeding and release in Brazil was carried out for non‐native fishes in the northwest region, which improved fishery yields significantly (Paiva et al., 1994). Nowadays, stock enhancement has become a mandatory management action, which is considered a primary measure to mitigate the impacts of reservoirs on fish populations and protect ichthyofauna in Brazil (F. P. Arantes et al., 2011; Casimiro et al., 2022). In China, dam construction in the Yangtze River basin has significantly affected natural reproduction processes and decreased the fishery resources of FMCCs (Q. Peng et al., 2012).…”

River damming has brought great benefits to flood mitigation, energy and food production, and will continue to play a significant role in global energy supply, particularly in Asia, Africa, and South America. However, dams have extensively altered global river dynamics, including riverine connectivity, hydrological, thermal, sediment and solute regimes, and the channel morphology. These alterations have detrimental effects on the quality and quantity of fish habitat and associated impacts on aquatic life. Indeed, dams have been implicated in the decline of numerous fishes, emphasizing the need for effective conservation measures. Here, we present a global synthesis of critical issues concerning the impacts of river damming on physical fish habitats, with a particular focus on key fish species across continents. We also consider current fish conservation measures and their applicability in different contexts. Finally, we identify future research needs. The information presented herein will help support sustainable dam operation under the constraints of future climate change and human needs.

“…Another factor that harms native species populations regards the repopulation (storage) made by owners or concessionaries as an environmental reward, which defines the use of autochthonous species in watersheds. Even though they are local species, the release of exotic individuals in the environment, without any scientific criteria, may affect several populations of native species existing in natural environments (30,5) . Therefore, inherent aspects related to changes in environmental law that favor the creation of IAS in reservoirs must be considered.…”

The introduction of invasive alien species (IAS) is among the leading causes of biodiversity loss in the world. The arrival of these species causes several imbalances in the natural environment. The establishment of these species depends on their transport, entry, adaptive success, and interactions in the environment. This work aims to present 12 species of exotic invasive fish that occur in natural environments in Brazil in the form of a booklet and to discuss some aspects inherent to legislation changes related to the cultivation of these species. The target audience of this study is mainly fish farmers, fishermen, riverside dwellers, assistance technicians, schools, environmental departments, and rural communities. The list had as a criterion the selection of species that are raised in fish farming stations and that already have records of occurrence in natural ecosystems in the country. These are exotic species introduced (from other countries) and with high invasive potential in Brazilian continental waters. To compose the list of these species, national and international studies that discuss the subject were sought, the following species being selected: Ctenopharyngodon idella, Hypophthalmichthys molitrix, Hypophthalmichthys nobilis, Cyprinus carpio, Oreochromis niloticus, Coptodon Rendalli, Oreochromis mossambicus, Oreochromis macrochir, Clarias gariepinus, Ictalurus punctatus, Oncorhynchus mykiss, Micropterus salmoides. In addition to presenting the impacts of invasive alien species on native ichthyofauna, this material will help disseminate technical information and may also be an aid to guide public policy decision making and awareness.
