1. Composição proximal e perfil de ácidos graxos de Hemigrapsus crenulatus (H. Milne Edwards, 1837) como um dos principais alimentos da “blenny patagônica” Eleginops maclovinus (Cuvier, 1830)
Resumo O “blenny da patagônia” (Eleginops maclovinus) é uma espécie endêmica da América do Sul, com características fisiológicas que facilitariam sua incorporação na aquicultura chilena. No entanto, atualmente não há alimento artificial específico que possa ser usado para criar E. maclovinus. Diante desse problema, este estudo descreve a comp

2. Biomarcadores enzimáticos e histológicos em brânquias de Ucides cordatus (Linnaeus, 1763) (Crustacea, Brachyura, Ucididae) indicativos de impactos ambientais em uma região portuária do nordeste do Brasil
RESUMO Objetivou-se neste estudo analisar biomarcadores histológicos e bioquímicos em brânquias de U. cordatus indicativos de impactos na Baía de São Marcos. Caranguejos foram coletados em quatro áreas na Baía de São Marcos: A1= Ilha dos Caranguejos (com baixo impacto); A2= Coqueiro, A3= Porto Grande, A4= Cajueiro (áreas potencialmente impactadas).

3. First record of the box crab Cryptosoma balguerii (Desbonne in Desbonne and Schramm, 1867) (Brachyura: Calappidae) from São Paulo, Brazil revealed by DNA markers
Abstract The present study provided information extending the known geographical distribution of the calappid crab Cryptosoma balguerii (Desbonne in Desbonne and Schramm, 1867). We provide new data that extends the range of this species in the western Atlantic farther to the south in the Brazilian region, State of São Paulo and check its identification by m

4. Natural diet of Ocypode quadrata (Fabricius, 1787) (Crustacea, Decapoda, Brachyura) from the Northern Coast of São Paulo, Brazil
Abstract Decapod crustaceans have a wide variety of feeding habits, alternating among herbivory, predation, saprophagy, and filtration. The occupation of various trophic positions in the food web is a key feature in the evolution of the group. Thus, we analyzed the natural diet of the crab Ocypode quadrata (Fabricius, 1787), commonly known as the ghost crab

5. Umalia trirufomaculata (Davie and Short, 1989) in India, with a note on the taxonomy of U. misakiensis (Sakai, 1937) (Decapoda: Brachyura: Raninidae)
Abstract The rare raninid crab Umalia trirufomaculata (Davie and Short, 1989) is recorded from India for the first time. It is redescribed and compared at length with the related but poorly known U. misakiensis (Sakai, 1937) on the basis of a good series of specimens from the Philippines. Some of the supposed differences which have been documented between th

6. A compilation of longevity data in decapod crustaceans
Abstract Longevity information was collected from 219 literature sources for 244 decapod crustaceans, representing 1.7% of species, 4.8% of genera and 30% of families. Reliable methods of age determination (laboratory rearing, mark-recapture method, growth models, lipofuscin method) revealed longevities from 0.1 to 72 years, corresponding to a 700-fold diffe

7. First confirmed record of the sesarmid crab, Parasesarma bengalense (Davie, 2003) (Decapoda: Brachyura) in Indian waters
ABSTRACT The mangrove crab, Parasesarma bengalense (Davie, 2003), was previously reported in an ecological study from the Coringa Wildlife Sanctuary of Andhra Pradesh on the east coast of India. No specimen, however, is readily available to confirm the identity of P. bengalense from the Coringa Wildlife Sanctuary. The present study confirms the presence of P

8. Intraspecific food resource partitioning in Brazilian silverside Atherinella brasiliensis (Atheriniformes: Atherinopsidae) in a tropical estuary, Brazil
RESUMO Nós investigamos a partição intraespecífica de recursos alimentares do peixe-rei Atherinella brasiliensis em um estuário tropical. Um total de 1.099 estômagos foi analisado, e a dieta foi constituída principalmente de Gastropoda, Larva de Ceratopogonidae, Larva de Decapoda, Calanoida, Cyclopoida, Hymenoptera e Brachyura. A análise de ordenaç�

9. Malacoplax californiensis (Lockington, 1877) (Crustacea: Decapoda: Brachyura: Panopeidae) in the Gulf of California, Mexico
Abstract A series of specimens of Malacoplax californiensis (Lockington, 1877) is reported from the Gulf of California, significantly increasing the known localities for the otherwise rarely reported species from 3 to 12. Depth range is increased to 110‒114 m on the continental shelf. Environmental conditions associated with the crabs were: 12.4‒27.0°C;

10. Decapod abundance and species richness in the bycatch of Xiphopenaeus kroyeri (Heller, 1862) fishery, Santa Catarina, southern Brazil
Abstract We aimed to analyze the crustacean bycatch from the Xiphopenaeus kroyeri fishery in the Santa Catarina State and compare the bycatch’s biomass to that of the target species. Shrimp and environmental factors were sampled monthly from July 2010 through June 2011. For each crustacean species, we calculated the number of individuals, the relative abun

11. Carcinoplax mistio, a new species of goneplacid crab from the Indian Ocean (Decapoda: Brachyura: Goneplacoidea)
Abstract Trawls from the Bay of Bengal obtained material of a new species of the goneplacid crab, Carcinoplax mistio, the sixth species of the genus known from India. The new species superficially resembles C. purpurea Rathbun, 1914, and C. sinica Chen, 1984, from the western Pacific. Records of C. sinica from the Persian Gulf are also here referred to the n

12. Distribuição espacial e temporal e abundância de duas espécies do gênero Persephona (Decapoda: Brachyura: Leucosiidae) no litoral sul do estado de São Paulo, Brasil
Resumo: Os caranguejos Persephona são intensamente capturados na pesca do camarão como fauna acompanhante, inclusive na região de Cananéia no litoral do estado de São Paulo, no Brasil. A avaliação da distribuição espaço-temporal pode, consequentemente, fornecer informações sobre variações na abundância de Persephona punctata e Persephona medit
