“…Its distribution occurs in the Atlantic Ocean from Venezuela, Colombia, Suriname, and Guyana up to Brazil (States of Amapá and Pará) (Melo, 2003). The records of this species in Brazil confirm the occurrence of the Lower Amazon and the river basins Tocatins (Pileggi et al, 2013).…”

Macrobrachium surinamicum is a small shrimp that inhabits rivers of low salinity. It is mainly caught as bycatch in Amazon shrimp Macrobrachium amazonicum fisheries, which is widely exploited by artisanal fisheries for food and economic needs of the riverside population. This study aimed to characterize the spatial and temporal distribution of the freshwater shrimp M. surinamicum in the Guajará Bay and on Mosqueiro Island, correlating the abundance of this species with abiotic factors (temperature and salinity). ResumoMacrobrachium surinamicum é um camarão de pequeno porte que habita a foz de rios e águas de baixa salinidade. Sua captura na Amazônia ocorre principalmente como fauna associada à pesca do camarão-da-Amazônia Macrobrachium amazonicum que é largamente explorado pela pesca artesanal atendendo as necessidades alimentícias e econômicas da comunidade ribeirinha. O presente estudo teve como objetivo caracterizar a distribuição espaço-temporal do camarão dulcícola M. surinamicum na Baía do Guajará e Ilha de Mosqueiro, correlacionando a abundância desta espécie com fatores abióticos (temperatura e salinidade). Os exemplares foram capturados no período de maio/06 a abril/07 em seis locais: Ilha de Mosqueiro (Furo das Marinhas e Porto do Pelé), Distrito de Icoaraci, Ilha do Arapiranga, orla de Belém e Ilha do Combu com armadilhas (matapis). Um total de 361 camarões foi capturado, sendo a maior abundância em dezembro e a menor em julho de 2006. A maior captura foi na Ilha de Arapiranga e a menor na Ilha de Mosqueiro. A abundância diferiu significativamente em dezembro/06 e nenhuma variável estudada teve influência significativa na abundância de M. surinamicum. A Baía do Guajará, especialmente os locais mais abrigados como a Ilha de Arapiranga e do Combu, propiciam o desenvolvimento de M. surinamicum, o que indica que esta espécie tenha preferência para áreas menos antropizadas.Palavras-chave: Crustacea, Decapoda, ecologia, camarão dulcícola.

“…Its occurrence covers all the main South American river basins, including the Orinoco, Amazon, Araguaia-Tocantins, São Francisco, Paraná and Paraguay, as well as the smaller rivers along the South Atlantic, in the northern and northeastern coasts of Brazil (Bialetzki et al, 1997;Magalhães, 2000;Melo, 2003;Vergamini et al, 2011;Pileggi et al, 2013).…”

ABSTRACT. The palaemonid shrimp Macrobrachium amazonicum is widely distributed in coastal rivers, estuaries and inland waters of South America. Despite this, little is known regarding its biology in the natural environment. Furthermore, this species is economically important because it is the main freshwater shrimp commercially exploited by artisanal fisheries in northern and northeastern Brazil, besides showing great potential for aquaculture. Considering this, the present study aimed to analyze aspects of the reproductive biology of M. amazonicum. A total of 251 females were analyzed, 102 of these being ovigerous. The carapace length ranged from 6.03 to 10.06 mm (average ± standard deviation: 7.52 ± 0.84 mm). Reproduction was continuous with a gradual increase from April to June 2012. No significant relationship between frequency of ovigerous females and environmental variables was observed. The fecundity showed a positive linear relation with the carapace length and the number of eggs varied from 33 to 389 (average ± standard deviation: 203 ± 78.06 eggs/female). A dominance of eggs at an early stage was observed in most months. There was an increase in the size/volume of eggs from early to late embryonic stage. Ovigerous females produced eggs at the same development stage, with the same size and volume regardless of their body size. The results demonstrated higher similarity of this population to other continental M. amazonicum populations than from estuarine ones, showing the environment influence in the life-history of individuals.

“…Recently, new ecological surveys have reported for the first time the occurrence of M. brasiliense in the states of Amapá, Tocantins, and Mato Grosso do Sul (Pileggi et al 2013). Given this wide geographic distribution, it is important to highlight that most of the studies which have been conducted to date involve species distribution and taxonomic reviews (Kensley & Walker 1982, Coelho & Ramos-Porto 1984, García-Dávila & Magalhães 2003, Pileggi & Mantelatto 2012.…”

HABITAT CHOICE BEHAVIOR IN Macrobrachium brasiliense (HELLER, 1862) (DECAPODA, PALAEMONIDAE) UNDER LABORATORY CONDITIONS

Abstract:The main objective of this study was to analyze the choice behavior of adult individuals of Macrobrachium brasiliense (Decapoda, Palaemonidae) with regard to different substrates and microhabitats in two distinct experiments. The first experiment offered the prawns three samples of substrates with different granulometries: fine sand, coarse sand, and gravel. The second experiment offered three types of microhabitats: aquatic macrophytes, wood fragments, and rocks. In general, the prawns chose the fine substrate, to a significant extent (ANOVA, p < 0.01). In the microhabitat experiment, the prawns selected the wood fragments (ANOVA, p < 0.01). In general, these results show that substrates with fine sand and microhabitats composed of fragments of wood might provide direct benefits for M. brasiliense, such as protection against predators and food availability through biofilm formation.
