Red mangrove crab Ucides occidentalis (Ortmann, 1987) (Brachyura: Ocypodidae): complete embryonic development under laboratory conditions

Latin American Journal of Aquatic Research, 2022
The red crab Ucides occidentalis (locally called "guariche") is widely distributed along Ecuador's coastline and is the most important crustacean fishery exploited by local coastal communities. However, a lack of information on the species' reproductive cycle has hindered conservation and sustainable management initiatives.

The nutritional quality of the red mangrove crab (Ucides occidentalis), harvested at two reserves in the Guayas estuary

Food Chemistry, 2023
Crabs are an outstanding source of many essential nutrients. Little research has been performed on the nutritional quality of the red mangrove crab (Ucides occidentalis). In this research we investigated the proximate composition, fatty acid profile, amino acid composition, and mineral concentrations of red mangrove crabs sampled at two reserves within
