1. Sample Preparation Using TMAH and Nitric Acid for Multielement Determination in Crustacean Samples by MIP OES
This study proposes a simple sample preparation procedure using tetramethylammonium hydroxide (TMAH) and nitric acid (HNO3) to determine Cr, Cu, Fe, K, Mg, Mn, and Zn concentrations in shrimp (Macrobrachium amazonicum) and crab (Ucides cordatus) samples from the Amazon region by microwave-induced plasma optical emission spectrometry (MIP OES). The sample sol

2. Residue-Based CaO Heterogeneous Catalysts from Crab and Mollusk Shells for FAME Production Via Transesterification
The production of fatty acid methyl esther (FAME) via transesterification was studied, assessing the influence of CaO heterogeneous catalysts obtained from four different fishery residues: sururu, crab, clam and mussel. Characterization and properties of the residues were obtained via thermogravimetric analysis, X-ray diffraction, X-ray fluorescence, Fourier

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. First record of Brachyuran crab Rhinolambrus lippus (Lanchester, 1901) (Crustacea: Decapoda: Parthenopidae) from India
Abstract The present paper reports the occurrence of the rare parthenopid species Rhinolambrus lippus (Lanchester, 1901) for the first time from India. The species is so far reported from Malaysia, Djibouti and Madagascar.

5. 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

6. Preparation of gluten-free crab nugget (Ucidescordatus) with added fiber
RESUMO: O caranguejo é rico em nutrientes, como os ácidos graxos poli-insaturados, minerais e vitaminas. A sua captura é uma das modalidades de pesca de maior importância paraense, porém é subutilizado na indústria alimentícia, vendido principalmente na forma in natura. O objetivo deste estudo foi desenvolver três formulações de empanado (nugget)

7. Use of osmoregulatory ability to predict invasiveness of the Indo-Pacific swimming crab Charybdis hellerii (A. Milne-Edwards, 1867) an invader in Southern Brazil
Abstract The Indo-Pacific swimming crab Charybdis hellerii (A. Milne-Edwards, 1867) is native to the Indo-Pacific Ocean, and occurs as an invasive species along the Eastern American coast, where it was probably introduced in ballast water. The present study evaluated the osmoregulation and salinity tolerance of C. hellerii in Paranaguá Bay, Paraná, Brazil,

8. 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

9. 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

10. 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

11. New records of two species of parasitic isopods (Isopoda: Cymothoida: Bopyridae: Athelginae) associated with hermit crabs from the south Atlantic
Abstract Two species of bopyrid isopods from the subfamily Athelginae are recorded from new localities in northeastern Brazil. Parathelges foliatus Markham, 1972 was recorded for the first time from Brazil, in the state of Ceará, parasitising the hermit crab Clibanarius symmetricus (Randall, 1840). Pseudostegias atlantica Lemos de Castro, 1965 is recorded f

12. Sustainable production with obtaining glucosamine from crab exoskeletons
RESUMO: Dois tratamentos químicos, cinco enzimáticos (pectinase, lipase, hemicelulase, hemicelulose-celulase ou lipase-pectinase) e um microbiológico (Bacillus subtilis) foram avaliados para obter o cloridrato de glucosamina (Gluc-HCl) da quitina obtida a partir de exoesqueletos de caranguejo (Callinectes. Bellicosus). Os dois tratamentos químicos foram
