25. 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

26. 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

27. Processamento de informação em neurônios motores de um centro gerador de padrões / Information processing in motor neurons of a central pattern generator
A atividade de neurônios em rajadas de disparo (bursts) é onipresente em sistemas nervosos. No entanto, o papel funcional dos bursts na codificação de informação ainda não é completamente compreendido. A dinâmica de burst tem sido intensivamente estudada em centros geradores de padrões (CPGs) que são exemplos clássicos de sistema nervoso autônom

28. Projeto raia de fogo: aspectos populacionais da raia de fogo (Dasyatis marianae Gomes, Rosa &Gadig, 2000) e pesca de elasmobrânquios no complexo recifal do Parracho de Maracajaú
The species Dasyatis marianae inhabits coastal areas associated with coral reefs, considered endemic to the northeast of Brazil, occurring from the State of Maranhão to the south of Bahia. Specimens of this species are commonly sighted by divers and fishermen in the area of Maracajaú reefs, a complex reef that is part of the Environmental Protection Area o

29. Illustrated key to the Brazilian Dendrocephalus (Crustacea: Anostraca: Thamnocephalidae)
The Anostraca is a diversified crustacean group inhabiting essentially in temporary wetlands on all continents. The genus Dendrocephalus sensu stricto is endemic to tropical or subtropical Neotropical fresh water pools. Of the 13 described species, four are reported from Brazil. Species identification is based on morphological differences on the complex fron

30. Ontogenesis and functional morphology of the digestive system of the freshwater prawn, Macrobrachium amazonicum (Decapoda: Palaemonidae)
The appropriate feeding regime for larvae and post-larvae of crustacean decapods is essential for successful larval culture. Reports on the development and morphology of the mouthparts and foregut of these crustaceans have aided in the selection of appropriate larval foodstuffs and consequently increased larval survival and growth rate during development. In

31. 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

32. A Pesca Industrial de Emalhe de Fundo em Santa Catarina-Brasil: Dinâmica, Tecnologia, Economia e Gestão
The gillnet fishery is a passive gear used to catch fish and crustacean species. Among the industrial fleet within the State of Santa Catarina which applies this technique, the main target-species are demersal fishes such as monkfish, whitemouth croaker and argentine croaker. The current work presents a study focused on the dynamic, economical and technologi

33. Implantação da piscicultura familiar com pescadores e agricultores assentados no Município de Lucena-PB
Fishing is a very important activity for the provision of protein, but as a result of the heavy pressure from extractive fishing and above the limits of carrying capacity of populations of commercial species, many stocks are at or above the limit of exploration, which has resulted in decreased populations of many animals, including driving some to extinction

34. 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

35. 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

36. Isolamento e caracterizaÃÃo parcial dos Genes beta-actina e miosina de cadeia pesada do CamarÃo rosa Farfantepenaeus subtilis / Isolation and partial characterization of genes beta-actin and myosin heavy chain shrimp Farfantepenaeus subtilis
The penaeid shrimp Farfantepenaeus subtilis is an important native species for fisheries industry in Brazil. Among marine shrimps of commercial importance, penaeids are recognized as a valuable resource for fishery and aquaculture in tropical and subtropical regions. However, data on these species is extremely reduced, especially concerning genetic elements
