RESUMO:

The decapod crustaceans represent one of the groups more plentiful and diverse in  marine environments in consolidated and unconsolidated areas. Constituent coastal regions are the major portion of human population density and, through direct and indirect actions, may negatively impact diversity and population structure and assembly. So, the study aimed to analyze the richness and seasonal and spatial crustacean fauna decapod accompanying the shrimp trawling Xiphopenaeus kroyeri, in city of Baía Formosa, Rio Grande do Norte, constituting an official first species list, with bycatch data of trawling, for the state and a distribution study. The field work were in the litoral regions of not consolidated in the municipality of Baía Formosa, monthly (March / 2013 to February / 2015), through a small fishing boat with a single type door net trawl, 6 tows georeferenced standardized time (20min), collected as being environmental variables susceptible to seasonal variation like water transparency (g / L), pressure (kPa), salinity (ppm), dissolved oxygen (mg / L), pH, temperature (° C ), rainfall (mm) and wind speed (m / s). Were captured total hum of 23,218 animals, which belong to Achelata, Brachyura, Caridea, Dendrobranchiata and Anomura, totaling 57 species, among them: Acetes americanus, Alpheus intrinsecus, Nematopalaemon schmitti Xiphopenaeus kroyeri, Litopenaeus schmitti, Callinectes ornatus and Petrochirus Diogenes, as the specie more abundant. Besides the new occurrence for state (Lysmata. cf. bahia), there are species with a lot of economic appeal, as Xiphopenaeus kroyerii, which got a greater abundance, showing the importance of preservation this area. For the other species, the result already expected for the region, since the animals described are found in regions with similar geographical features.
