“…Besides the Amazon region, the impacts of hydroelectric dams on the fish fauna and the decline of important commercial species have also been found in other aquatic ecosystems around the world (e.g., Agostinho et al., ; Assis et al., ; Dugan et al., ; Neraas & Spruell, ; Stone, ; Zhong & Power, ). For instance, a study of the effects of the Tallowa dam on the Shoalhaven River (south‐east Australia) found a reduction in the abundance of four species of migratory fish and possibly the extinction of another ten species (Gehrke, Gillgian & Barwick, ).…”

“…The regression indicated that, independently of any variation in the level of the river, damming alone was responsible for a reduction of 2,305 kg (10.1%) in the mean fishery production ( Figure 6). Besides the Amazon region, the impacts of hydroelectric dams on the fish fauna and the decline of important commercial species have also been found in other aquatic ecosystems around the world (e.g., Agostinho et al, 2008;Assis et al, 2017;Dugan et al, 2010;Neraas & Spruell, 2001;Stone, 2016;Zhong & Power, 1996). The construction of hydroelectric dams in Amazonian ecosystems represents a major risk for the local fish fauna, especially considering that fishery productivity in this region reflects the enormous diversity of fish species found in the Amazon basin.…”

“…The change from a lotic to a lentic environment also favours the invasion of non-native species, creating a high risk of regional colonization (Assis, Dias-Filho, Magalhães & Brito, 2017). This type of impact is not yet common in Amazon ecosystems.…”

Despite being considered beneficial by providing a clean and renewable source of energy, the construction of hydroelectric dams has extremely negative implications for Amazonian fisheries. This study investigated the impacts of the Santo Antônio and Jirau hydroelectric dams on the fishery stocks of the Madeira River. This investigation was based on fish catch data from the Z‐31 fishing colony, located in the municipality of Humaitá, in Amazonas State, Northern Brazil. Data were collected daily and provided information on the date of return from each trip, the fish species targeted, and the total catch (kg) between January 2002 and September 2017. The results indicated reductions of 39% in the mean annual catch and 34% in the mean monthly catches. These results highlight the high price paid by local fish communities for the development of hydroelectric power in the Amazon basin.

“…Esses resultados indicam uma possível quebra do ciclo de vida biológico resultando no desaparecimento de espécies nativas e invasão de espécies exóticas [30] pois a diversidade do rio está associada ao seu ciclo hidrológico pois a vazão é fator determinante no habitat, as espécies evoluíram adaptadas ao regime natural, assim a manutenção deste regime provê sustentabilidade para estas espécies e assim quaisquer alterações no ciclo hidrológico facilitam a invasão e o sucesso de espécies exóticas [26,[45][46].…”

Um ecossistema equilibrado é a base da vida e desenvolvimento de milhares de espécies de seres vivos. Os rios fazem um papel muito importante nesse equilíbrio. Um dos mais importantes rios do Brasil é o Rio São Francisco que contém, ao longo do seu percurso, cinco usinas hidrelétricas. As hidrelétricas são uma das fontes de energia mais baratas entre as disponíveis, por isso é a mais usada, porém a construção de hidrelétricas causa vários impactos ao meio ambiente. Para avaliar este impacto, fornecendo base para uma avaliação mais criteriosa na escolha do método de obtenção de energia e um melhor planejamento nas futuras construções de hidrelétricas, foi usado o método de Indicadores de Alteração Hidrológica (IAH) para estudar a variabilidade das características hidrológicas da vazão observada diariamente abaixo da represa de Sobradinho. Foram retirados da análise anos com chuva muito abaixo ou muito acima do normal. A partir desses dados, o método IAH gera 33 indicadores hidrológicos de relevância ecológica. Todos os indicadores de alteração hidrológica foram avaliados e os resultados mostraram que, quando comparamos o período anterior à construção da barragem com o período posterior, houve alteração hidrológica em todos os indicadores hidrológicos fornecidos pelo método de IAH.

“…The natural distribution of Metynnis lippincottianus (Cope, 1870), common name in Brazil: "pacu" or "pacu-marreca", includes the Amazon River basin and the Guiana shield in the Northeast of the continent (FROESE & PAULY, 2017); however, it has expanded its geographic range to other South American watersheds (OTA et al, 2016). Since 2004 M. lippincottianus has been fished at the Três Marias Reservoir, upper São Francisco River basin, State of Minas Gerais, Southeast Brazil (SATO & SAMPAIO, 2006;OTA et al, 2016) as well as in the middle (LUZ et al, 2009) and lower São Francisco River (ASSIS et al, 2017). Most of the fish allochthonous species that occur in Brazilian aquatic ecosystems were introduced via anthropogenic action such as fish farming, pest control, and fishkeeping, and has as a consequence the inadvertent, accidental introduction of parasites in these freshwater environments (AGOSTINHO et al, 2005).…”

Metynnis lippincottianus is a freshwater native fish to the Guiana basin and Amazon basin and was recently introduced into the São Francisco River in Brazil. This study aimed to determine the helminths parasites of M. lippincottianus from the Três Marias Reservoir, upper São Francisco River, State of Minas Gerais, Southeast Brazil. From 67 hosts examined, 63 were parasitized by 9,257 helminths represented by five species: Dadayius sp. [prevalence (P) = 1.49%, mean abundance (MA) = 0.01]; proteocephalid plerocercoids (P = 43.28%, MA = 5.04); Procamallanus (Spirocamallanus) inopinatus (P = 29.85%, MA = 0.54); Spinitectus rodolphiheringi (P = 2.99%, MA = 0.03); Spinoxyuris sp. (P = 85.07%, MA = 132.54). These findings show that M. lippincottianus is an additional host to the helminths infecting fish native to the São Francisco River (plerocercoids, P. (S.) inopinatus and S. rodolphiheringi), and highlight the fact that Dadayius sp. and Spinoxyuris sp., which were typically found in native Metynnis spp. in other basins, also parasitizing the non-native serrasalmid M. lippincottianus in São Francisco River. These two helminth species have thrived in this freshwater ecosystem with the expansion of the geographical distribution of the host species to the São Francisco River.
