          Abstract

          The introduction of non-native species in inland waters is one of the main threats for aquatic biodiversity. Introduced species may compete for resources, prey on native fauna, spread diseases and parasites. The channel catfish Ictalurus punctatus (Siluriformes, Ictaluridae) was first described by Rafinesque 1818 in the United States and is widely distributed in North America, south Canada and north-east Mexico. This species adapts easily to new environmental conditions, is tolerant to different habitats, and is grown easily in aquaculture, which turns it into a potential invader of natural aquatic environments. The introduction of I. punctatus occurs in Brazil since 1980, and this is the first record of its occurrence in the Rio dos Sinos basin, Brazil. A female adult catfish was captured during a survey in the main channel of the Rio dos Sinos (29º 44' 14.04" S and 51º 05' 11.08" W). Most probably the captured individual is an escapee from nearby aquaculture facilities.

          A introdução de peixes não nativos em águas interiores é uma das principais ameaças à biodiversidade. Espécies introduzidas podem competir por recursos, predar a fauna nativa, transmitir doenças e parasitas. O bagre americano, Ictalurus punctatus (Siluriformes, Ictaluridae), foi descrito por Rafinesque em 1818 nos Estados Unidos. Possui ampla distribuição na América do Norte, Sul do Canadá, e Nordeste do México. A espécie apresenta alto valor comercial devido ao fato de adaptar-se facilmente a novos ambientes, tolerar variações ambientais, e ser de fácil cultivo. Como todas as espécies exóticas ou alóctones criadas na aqüicultura, é um potencial invasor aos ambientes aquáticos naturais. No Brasil, sua introdução ocorre desde o ano 1980. Este é o primeiro registro de ocorrência de I. punctatus, para a bacia do Rio dos Sinos, São Leopoldo, Brasil. A captura de uma fêmea adulta foi realizada durante um levantamento ictiofaunístico na calha principal do Rio dos Sinos (29º 44' 14.04" S e 51º 05' 11.08" W). O individuo capturado provavelmente representa o resultado de escape de uma estação de piscicultura.

          Homogenization of fish faunas across the United States.

          Fish faunas across the continental United States have become more similar through time because of widespread introductions of a group of cosmopolitan species intended to enhance food and sport fisheries. On average, pairs of states have 15.4 more species in common now than before European settlement of North America. The 89 pairs of states that formerly had no species in common now share an average of 25.2 species. Introductions have played a larger role than extirpations in homogenizing fish faunas. Western and New England states have received the most introductions, which is a reflection of the small number of native fishes in these areas considered desirable gamefish by settlers.
