Abstract

Abstract:: Aim: Non-native fish species have been closely related to serious damage to aquatic biodiversity due to their negative effects on native fauna. We aim to report the first and alarming occurrence of the non-native catfish “jaú” Zungaro jahu in the Iguaçu River basin above the Iguaçu Falls, a high-endemism Neotropical ecoregion for fish.

Methods: Fish samplings were taken with a bottom gill net in the Segredo Reservoir, where they were anesthetized in benzocaine hydrochloride and fixed in formaldehyde in the field, later identified in the laboratory and housed at the Museu de História Natural do Capão da Imbuia (MHNCI).

Results: Our recent samplings in the Iguaçu River basin recorded one non-native individual of the catfish “jaú” Zungaro jahu in the Segredo Reservoir.

Conclusions: We mainly intend to alarm about the risk of expansion of the occurrence of this non-native species throughout the cascading reservoirs in the Iguaçu River where it could potentially develop serious damage to the trophic chain, predation of small-sized endemic species, and competition, especially in the sites where the endemic and endangered pimelodid “surubim-do-iguaçu” (Steindachneridion melanodermatum) maintains viable populations, currently restricted to the Lower Iguaçu River basin exhibiting recent signs of a population bottleneck.

Resumo

Resumo:: Objetivo: Espécies de peixes não nativas têm sido intimamente relacionadas aos sérios danos à biodiversidade aquática devido aos efeitos negativos sobre a fauna nativa. Nosso objetivo é relatar a primeira e alarmante ocorrência do bagre não nativo “jaú” Zungaro jahu na bacia do rio Iguaçu acima das Cataratas do Iguaçu, uma ecorregião neotropical com alto endemismo de peixes.

Métodos: As amostragens dos peixes foram realizadas com rede de emalhar de fundo no Reservatório de Segredo, onde foram anestesiados em cloridrato de benzocaína e fixados em formol em campo, posteriormente foram identificados em laboratório e depositados no Museu de História Natural do Capão da Imbuia (MHNCI).

Resultados: Nossas amostragens recentes na bacia do rio Iguaçu registraram um indivíduo não nativo do bagre “jaú” Zungaro jahu no Reservatório de Segredo.

Conclusões: Pretendemos, principalmente, alertar sobre o risco de expansão da ocorrência desta espécie não nativa ao longo da cascata de reservatórios do rio Iguaçu, onde potencialmente poderá desenvolver sérios danos à cadeia trófica, predação de espécies endêmicas de pequeno porte e competição, especialmente nos locais onde o pimelodídeo endêmico e ameaçado de extinção “surubim-do-iguaçu” (Steindachneridion melanodermatum) mantém populações viáveis, atualmente restrita à bacia do Baixo rio Iguaçu, exibindo sinais recentes do efeito de gargalo.
