1. Setogenesis and characterization of the new moult substages in the freshwater shrimp Palaemon argentinus (Nobili, 1901) (Caridea: Palaemonidae)
Abstract The moult cycle of crustaceans is continuous and during different stages of this cycle, physiological, biochemical and morphological changes occur. Therefore, understanding the different stages of the moult cycle in the target species becomes critical for a wide range of biological studies. Here we describe the natural cycle changes in the freshwate

2. Low levels of crustacean parasite infestation in fish species from the Matapi River in the state of Amapá, Brazil
Resumo Este primeiro estudo investigou a fauna parasitária de crustáceos em 66 espécies de peixes da bacia do Rio Matapi, estado do Amapá (Brasil). Os peixes foram coletados bimestralmente no período de março de 2012 a agosto de 2013, nas estações de estiagem e chuvosa. Entre as 66 espécies (correspondendo a 722 espécimes) somente 11 espécies esta

3. Checklist of fossil decapod crustaceans from tropical America. Part I: Anomura and Brachyura
Abstract Our knowledge of fossil crustaceans from the tropics has increased considerably during recent decades, thanks to novel findings and the re-examination of museum specimens. However, several previous records have been misidentified, numerous museum specimens have never been reported, and many new discoveries are yet to be published. Here, we present a

4. The use of lysozyme to prepare biologically active chitooligomers
Two types of crustacean commercial chitosans (CS1, CS2) were dissolved in lactic acid solutions, hydrolysed by lysozyme and finally fractioned by methanol solutions into two parts containing chito-oligomers (CS-O1, CS-O2). The antioxidant power and antimicrobial properties of both fractions were studied and compared with non-hydrolysed CS1 and CS2. The antio

5. Composition and seasonal variation of brachyura and anomura (Crustacea, Decapoda) associated with brown mussel farms at Praia da Cocanha, Brazil
The composition and seasonal variation of brachyuran and anomuran species associated with mussel farms were evaluated at Praia da Cocanha, São Paulo between May 2007 and February 2008. Nine mussel ropes were sampled at random in each quarter, and 1,208 organisms were identified, comprising five families and 28 species. The most numerous species was the porc

6. Tributyltin in crustacean tissues: analytical performance and validation of method
O ermitão Clibanarius vittatus é um organismo típico de regiões intertidais estuarinas sendo considerado um possível bioindicador da presença de tributilestanho (TBT) nesses ambientes. Por esta razão, este estudo apresenta o desempenho analítico e a validação do método para quantificação de TBT em tecidos de C. vittatus por cromatografia gasosa

7. Aplicação de quitosana como suporte para a imobilização de enzimas de interesse industrial
Chitosan, poly[β-(1-4)-linked-2-amino-2-deoxy-D-glucose], is the N-deacetylated product of chitin which is a major component of arthropod and crustacean shells such as lobsters, crabs, shrimps, and cuttlefishes. In addition, chitosan has many significant biological and chemical properties such as biodegradability, biocompatibility and bioactivity as well as

8. A transcriptome analysis of mitten crab testes (Eriocheir sinensis)
The identification of expressed genes involved in sexual precocity of the mitten crab (Eriocheir sinensis) is critical for a better understanding of its reproductive development. To this end, we constructed a cDNA library from the rapid developmental stage of testis of E. sinensis and sequenced 3,388 randomly picked clones. After processing, 2,990 high-quali

9. Conhecimento Ecológico Local, Técnicas de Pesca e Uso dos Recursos Pesqueiros em Comunidades da Área de Proteção Ambiental Barra do Rio Mamanguape, Paraíba, Brasil.
This study was conducted among three coastal communities: Aritingui, Taberaba and Tavares, located on the right of the estuary of Mamanguape River (EMR) in Paraíba, and incorporated in the Environmental Protection Area of the namesake river. Its main objective is to study the local ecological knowledge and use of wildlife resources by fishermen and collecto

11. Uso do solo na Bacia Hidrográfica do rio Camboriú (SC) e sua influência sobre a qualidade da água
The watershed of the Camboriú River is located in the cities of Camboriú and Balneário Camboriú. With a length of around 40 kilometers, it drains an area of 200 km2. This paper aims to characterize the Camboriú River watershed by determining space-time variations of physical, chemical and biological parameters of superficial water, as well as the soil o

12. Mercury concentration in the freshwater bonefish Cyphocharax gilbert (Curimatidae) and its parasite the crustacean Riggia paranensis (Cymothoidae)
Parasitos de peixes podem acumular metais pesados em concentrações acima dos hospedeiros, podendo afetar a bioacumulação nestes. O presente estudo comparou a concentração total do mercúrio no fígado e no músculo de Cyphocharax gilbert e no parasito Riggia paranensis, coletados no trecho médio do rio Itabapoana, Brasil, considerando o estágio repro
