Ictiofauna de campos alagados da Ilha do Marajó, Estado do Pará, Brasil

Abstract: Os campos alagados ou savanas da ilha do Marajó é uma área disjunta do bioma Cerrado na Amazônia, e é considerada de grande importância para planos de manejo, conservação e preservação ambiental. A fim de ampliar o conhecimento ictiofaunístico da região, o presente estudo reuniu informações coletadas em campo, compiladas da literatura e selecionadas de coleções ictiológicas sobre a fauna de peixes da eco-região savana do Marajó. As coletas de campo ocorreram entre os anos de 2003 e 2005, e apresentaram como mé… Show more

“…The specimen measured 24 cm total length and 135 g total weight (Figure 3). The species is found only in the northern region of Brazil (Menezes et al 2003;Montag et al 2009) and the present record represents the southernmost occurrence and extension of its geographical distribution. New record for the northeastern Brazil.…”

“…Long-term interaction between human societies and the environment has found a prodigal field study in Marajó Island [7]. As previously reported, the history of human occupation of the island dates from about 5000 years before present, showing a long background, up to the present, of aquatic resource management [5]- [7]. Seasonally, flooded savannas as a natural fish nursery were from time to time and successfully managed in order to feed indigenous and subsequently early settlers [5]- [7].…”

“…The local climate can be characterized by two categories: humid tropical, with mean precipitation in the driest month at least 60 mm, and tropical monsoon, with excessive rainfall between January and June. During this period, two thirds of the island is completely flooded [2]- [5]. The annual precipitation ranges between 2500 mm and 4000 mm, with a mean temperature of around 27˚C, and relative humidity bordering on 80%.…”

“…Igarapés de oresta de terra rme são componentes importantes do sistema uvial amazônico (WELCOMME, 1985), que abrigam um grande número de espécies de peixes (BÜHRNHEIM; COX-FERNANDES, 2003;MONTAG et al, 2009;OLIVEIRA et al, 2009;BARROS et al, 2011) principalmente de porte pequeno, com comprimento total menor que 100 mm (BÜHRNHEIM, 2002). Este ambiente apresenta diversidade de habitats menor do que de rios, possuindo geralmente dois ambientes típicos: ambientes de alta velocidade de correnteza, com substrato composto principalmente por areia, seixos, raízes de plantas e troncos submersos; e ambientes de poções mais profundos, formados em áreas de baixa velocidade de correnteza, normalmente nos retornos dos meandros do canal ou após barreiras naturais (e.g.…”
