O Programa de Pós-Graduação em Ecologia Aquática e Pesca (PPGEAP) integra o Núcleo de Ecologia Aquática e Pesca da Amazônia (NEAP) da Universidade Federal do Pará (UFPA). Focaliza os problemas relacionados com a conservação e com a gestão dos ecossistemas aquáticos amazônicos, decorrentes do uso dos seus recursos naturais pelo homem, em particular os recursos pesqueiros, para atividades de desenvolvimento econômico e regional.Tem como objetivo geral capacitar recursos humanos capazes de compreender de forma integrada a complexa dinâmica dos ecossistemas aquáticos da Amazônia, visando o uso racional dos seus recursos e sua conservação.

    Assembleias de ciclídeos na área focal da Reserva de Desenvolvimento Sustentável Mamirauá, médio Rio Solimões, Amazonas, Brasil
    (Universidade Federal do Pará, 2010-03-19) PEREIRA, Ludmilla Costa Ferreira; CAMARGO-ZORRO, Mauricio; http://lattes.cnpq.br/5423657235023988
    This study aims to know the fish diversity of the family Cichlidae in different habitats (lakes, ressacas and river banks) and habitats (floating macrophytes, branches and beaches) on Sustainable Development Reserve Mamiraua (RDSM), medium Solimoes River, Amazonas. Samples were collected in two periods: 1) Three months sampled in March, July and December 2003 in 21 environments; 2) from September 2003 to August 2004 in five lakes with presence of the floating meadows Eichornia crassipes and Paspalum repens. Were used gillnets, hand nets and seine nets. Were collected 6397 fishes and 350 kilograms, represented in 28 species and 16 genera. Cichlids represented approximately 35% of the total number of fish collected. The composition of the catch was dominated by juvenile forms or small fishes. Mesonauta insignis and Cichlassoma amazonarum dominate in abundance and weight along the study. Species richness was larger in the period I (28 species), while during the period II were recorded 19 species. Nine species were absent in lakes with floating meadows. The study showed that the cichlids moving between environments and habitats of the Reserve in search of better conditions for their survival.

    Dinâmica espaço-temporal da pesca industrial de camarão-rosa Farfantepenaeus subtilis na plataforma continental do Amazonas
    (Universidade Federal do Pará, 2011-05-18) MARTINS, Déborah Elena Galvão; SOUZA FILHO, Pedro Walfir Martins e; http://lattes.cnpq.br/3282736820907252; CAMARGO-ZORRO, Mauricio; http://lattes.cnpq.br/5423657235023988
    Knowledge of spatial distribution of fishing resources is essential to fisheries management. The southern brown shrimp Farfantepenaeus subtilis (Perez-Farfante, 1967) is an industrial fishing fleet target on the Amazon Continental Shelf. This study aimed to evaluate F. subtilis relative abundance spatial-temporal patterns from commercial fishery data, using Geographic Information System tools. Catch per unit effort (CPUE), used as index of relative abundance, was related to bathymetry, substrate characteristics, Amazon river flow and the oceanographic variables obtained by remote sensing: sea surface temperature and chlorophyll-a concentration. Analyzing substrate characteristics, the commercial shrimp trawls were concentrated at the mottled mud region, where the overlap of environmental factors was crucial for a higher incidence of F. subtilis. In this region, features such as substrate (mud), sedimentation rate (<1 cm.yr-1) and salinity (> 30) are the ideal habitat for F. subtilis. Higher CPUE values were associated with lower temperatures and higher values of chlorophyll-a concentration, which occur at the greatest flow of the Amazon river, during the first six months of the year. It was observed the occurrence of three periods with different levels of production along the year: from February to April, with higher CPUE of southern brown shrimp, from May to July, and August to September, with lower CPUE. The results showed that relative abundance of F. subtilis is not distributed uniformly in space nor in seasonal variation.

    Ecomorfologia trófica de Acarichthys heckelii (Müller & Troschel, 1849), Heros efasciatus Heckel, 1840 e Mesonauta insignis (Heckel, 1840) (Perciformes:Cichlidae) nas reservas de desenvolvimento sustentável de Amanã e Mamirauá, Amazônia
    (Universidade Federal do Pará, 2011-08-18) LINS, Paulo Marcelo de Oliveira; CAMARGO-ZORRO, Mauricio; http://lattes.cnpq.br/5423657235023988
    The cichlids are one of the most diverse families of living freshwater fishes, about 1.900 species. A. heckelii, H. efasciatus and M. insignis are exploited at the Sustainable Development Reserves of Amanã and Mamirauá according to sustainable management plan. A free-size canonical variable analysis was made to investigate the ecomorphological patterns of variation among the three species from Amanã and Mamirauá Reserves. The three species formed different groups like species, ontogeny phase and habitat. Those groups were divided as result of characters like mouth width and head length. Differences among juveniles and adults were significant in relative area of eye and aspect-ratio of caudal fin. The diet composition indicated that three studied species have a converged feeding habit on insects in both black and white waters habitats.
