Biodiversity of decapod crustaceans in the estuarine floodplain around the city of Belém (Pará) in Brazilian Amazonia

Abstract: ABSTRACT. The present study focused on the decapod fauna of the fluvial-estuarine environment of the Guajará Bay, in Milne-Edwards, 1853). While no significant differences were found in the ecological indices of diversity with respect to season, site, or trap size, a tendency for increased abundance and species richness was found during the dry season (August-November), in particular at some sites, apparently reflecting the influence of the estuary's saline wedge.

“…Accordingly, a previous study on holoplanktonic luciferid shrimps (Melo et al, 2014) showed that their abundance decreased substantially along a gradient from the coast towards offshore waters, on the North Brazilian Shelf. Other studies of decapods in the study area were conducted by Cavalcante et al (2012), de Oliveira et al (2012), Carvalho et al (2013) and Nóbrega et al (2014). Nevertheless, most of these studies were carried out on the continental shelf close to the Amazon River mouth, and there are few published studies in oceanic areas near the shelf break and slope (Melo et al, 2014) or following the ARP (Calef and Grice, 1967;Conroy et al, 2016Conroy et al, , 2017.…”

“…Entre as espécies de decápodes de água doce do Brasil importantes ecológica e economicamente (Magalhães, 1999;Almeida et al, 2008;Cavalcante et al, 2012), o M. amazonicum é o de maior importância econômica no norte e nordeste, sendo amplamente pescado e consumido nestas regiões (Moraes-Riodades & Valenti, 2001Marques & Moraes-Valenti, 2012). A espécie apresenta um grande potencial para a aquicultura, pois apresenta características altamente favoráveis ao cultivo em cativeiros, pois trata-se de uma espécie nativa (Moraes-Valenti & Valenti, 2010) que apresenta crescimento rápido, resistência a doenças, alta taxa de sobrevivência, fácil manutenção (Marques & Moraes-Valenti, 2012), reprodução continua ao longo de todas as estações do ano (Sampaio et al, 2007;Pantaleão et al, 2018) e a possibilidade de produção de larvas em salinidades de apenas Introdução________________________________________________________________20 1 ‰S, permitindo a sua produção em regiões interioranas próximas das fazendas de engorda (Araujo & Valenti, 2010).…”
