| Two species of the crab family Cryptochyridae, Opecarcinus hypostegus (Shaw and Hopkins) and Troglocarcinus corallicola Verrill, are reported for the first time on the Caribbean coast of Colombia, thus extending the known distribution of the two species. For both species a short diagnosis and remarks on their distribution, depth range and association with corals are included. |

| Durante el período abril 2009 – 2010 se analizó la situación pesquera artesanal del recurso guariche o cangrejo rojo Ucides occidentalis (Ortmann, 1897) en el estuario del Río Chone, considerando desembarques comerciales y su hábitat “in situ”. El esfuerzo total promedio correspondió 84 recolectores/día pesca, con una captura promedio de 36 cangrejos o su equivalente a 6 sartas u atados. Se registró un 90% de ejemplares macho con talla promedio de 7.5 cm de ancho cefalotorácico (AC); mientras que el 10% de ejemplares hembras presento una talla promedio de 6.5 cm AC. El muestreo de densidad poblacional se lo realizo en 36 estaciones correspondiente a las seis localidades cangrejeras ubicadas en el estuario reportando una densidad de 0.7 cangrejos/m2.... |

| The potential long-term effects of altered salinity regimes on the bioenergetics of two ecologically important Kenyan mangrove crabs, Neosarmatium meinerti de Man, 1887 and Neosarmatium smithi H. Milne Edwards, 1853 were investigated in light of recent findings suggesting that groundwater redirection may alter salinity regimes in Kenyan mangroves. Although changes in groundwater may cause only small increases in salinities, these changes would be chronic and may impact crab populations already living above their optimal salinity. To assess potential impacts, fundamental physiological processes and hemolymph components were measured on animals acclimated to 16‰, 32‰, 48‰ and 65‰ for 4 weeks in a field laboratory. For comparative purposes, crabs were also... |

| Durante el 2009, se realizó el seguimiento de las capturas de cangrejo rojo (Ucides occidentalis), en las principales localidades de extracción de la provincia de El Oro y Guayas, la captura total estimada de cangrejos fue de 2 897 707 y 3 184 795 en las provincias mencionadas. Las localidades de Puerto Jelí y Puerto Baquerizo Moreno fueron las de mayor desembarque, lo que está relacionado directamente con el esfuerzo. La CPUE fue muy variada en los puertos monitoreados con valores que oscilaron entre 47 a 94 cangrejos hombre-1 día-1, obteniéndose mayores niveles en el periodo posterior a la época de veda. La distribución de tallas de amplitud del cefalotórax de los cangrejos capturados, en cada una de las localidades muestreadas, fue superior a la talla... |

| Uca annulipes (H. Milne Edwards, 1837) is probably the most abundant brachyuran crab inhabiting mangrove forests in East Africa. However, its fecundity is poorly understood. Crabs were randomly sampled during spring low tides from January to April 2002 at Costa do Sol mangrove, Maputo Bay, southern Mozambique. Carapace width (CW), abdomen width (AW), weight (W) and egg numbers (EN) were recorded. The average fecundity was 1599 ± 842 eggs, ranging from 529 (CW = 5.0 mm) to 4250 (CW = 24.1 mm) eggs respectively. Egg number increased significantly with increase in crab size. This information contributes to our knowledge of the reproductive potential and the reproductive processes occurring in this species of crab. |
