Caracterização da atividade pesqueira em Vila do Conde (Barcarena, Pará), no estuário amazônico

Abstract

Resumo: A região de Vila do Conde é um importante pólo industrial no sul da baía de Marajó. Apesar da importância da pesca e da vulnerabilidade da região em relação ao impacto ambiental, não há nenhum estudo aprofundado sobre a pesca e a ictiofauna na área. Abstract: Vila do Conde is an important industrial complex in the south of the Marajó Bay. Despite the important fishery activity and the vulnerability in terms of environmental impacts, no relevant scientific study on fishery and ichthyofauna has been carried out in the area. This study aimed to describe the fishing activity by monitoring commercial landings of the main site (Praia do Conde) of the region between December 2005 and November 2006. The relative abundance index, catch-per-unit-of-effort (CPUE in kg/fishing trip), was used to identify the harvest season, species and fleet most relevant in the region. Forty-three boats were monitored, mainly small wooden boats. The main fishing gear was the long-line. The main local species were Brachyplatystoma rousseauxii (dourada catfish), Plagioscion squamosissimus (South American silver croaker), Pellona flavipinnis (yellowfin river pellona), P. castelnaeana (Amazon pellona) e B. filamentosum (filhote). Fleets caught an average of 19 kg/trip. Motorised boats were more productive than non-motorised. Two maximum harvest periods were observed: in January and September/October. The gross revenue of the fishery was over R$ 100,000.00. Wooden small boats contributed to 36% of the total catch.

Ichthyofauna as bioindicator of environmental quality in an industrial district in the amazon estuary, Brazil

“…Studies have shown that the inner portion of the Amazon estuary, including Marajó and Guajará bays and the Pará estuary are used by ichthyofauna more for growth and development, rather than reproduction (Viana et al, 2010). In addition to the biological aspects of these phenomena, the local population is economically dependent on local fishery resources (Paz et al, 2011).…”

“…This study area is an estuarine environment with a considerable freshwater input, being classified as a tidal freshwater estuary according to the scheme of Elliott and McLusky (2002). Despite the intense industrial activity at the estuary of the Pará River, the area is an important artisanal fishing ground and the local population is highly dependent on fishery resources (Paz et al, 2011). In addition to its socio-economic importance, the area plays an important ecological role in the reproduction, feeding and development of many fish species.…”

Caracterização de parâmetros de qualidade da água na área portuária de Barcarena, PA, Brasil

“…Na porção continental, os solos predominantes são o Latossolo Amarelo distrófico, o Podzol Hidromórfico e Concrecionário Laterítico indiscriminado distrófico, textura indiscriminada (EMBRAPA, 2013). Entre as atividades produtivas destaca-se a agricultura, pesca artesanal e a indústria, principalmente pela locação de empresas com beneficiamento de alumínio implantado desde a década de 80 e em contínuo crescimento, decorrente de atividades minero-metalúrgicas e portuárias, sendo esta última devido à criação do Porto da Vila do Conde (Paz et al, 2011).…”

The reproductive biology ofPlagioscion squamosissimus(Heckel, 1840) in the Pará River estuary (Amazon Estuary)

“…The Para´River estuary, 40 km west of Bele´m, is an important artisanal fishing area characterised by the presence of several fishing grounds (Paz et al, 2011). This region is also relevant due to the high dependence of the population on the fishing resources.…”
