Growth and mortality of black bass, Micropterus salmoides (Pisces, Centrachidae; Lacapède, 1802) in a reservoir in southern Brazil

Abstract: The black bass, Micropterus salmoides, was introduced to Brazil from North America in 1922. Since then the species has been reared in aquaculture facilities intended to stock reservoirs as additions to native stocks available for angling. At present no scientific information on the biology of black bass in Brazilian waters is available. Since black bass dispersion may cause severe impacts on native Brazilian fish fauna, information on the basic biological parameters of this species is necessary. The objective … Show more

“…In Brazil, M. salmoides was introduced in Belo Horizonte, in 1922, for aquaculture purposes. Nowadays, it is distributed through artificial systems, such as lagoons and semi-natural reservoirs, from Rio de Janeiro to Rio Grande do Sul (Schulz and Leal 2005).…”

“…Em peixes tropicais, Pauly (1998) constatou que elevados valores de K e baixos valores de comprimento assintótico são comuns, e atribui a esse fato a combinação de vários fatores, sendo a temperatura o fator mais importante. Por se tratar de uma espécie piscívora (Géry 1977), o rápido crescimento é determinante contra a predação que pode ser iniciada ainda na fase de larvas (Schütz et al 2008) e para a melhor obtenção de alimento (Gerking 1994).…”

“…No entanto, a validação das classes etárias nem sempre é possível, devido principalmente às dificuldades inerentes para a obtenção de número razoável de exemplares ou a pequena definição dos anéis etários (Lizama & Vazzoler 1993). Apesar de toda a dificuldade encontrada, existem diversos trabalhos que fizeram uso da contagem dos anéis e obtiveram resultados na determinação da idade em peixes de águas tropicais (Barbieri et al 2001, Feitoza et al 2004, Penha et al 2004, Penna et al 2005, Schulz & Leal 2005.…”

“…Nevertheless, as in a completely contradictory way, the polycultural farming of commercial species such as tilapia (Oreochromis niloticus niloticus and Tilapia rendalli; Cichlidae) and grass carp (Ctenopharyngodon idella; Cyprinidae) is encouraged, even by state agencies. As recorded by FEPAGRO (Mardini et al 1997) more than 90% of the established commercial cultivations of the Rio Grande do Sul state are of exotic species, several of which are frequently recorded in inventories of fish assemblages in southern Brazil (Mardini et al 1997, Schulz & Leal 2005, Leal et al 2009, Winckler-Sosinski et al 2009, Leal et al 2010.…”
