The state of Roraima presents a great diversity of aquatic environments, such as lakes, buritis trails, wetlands, streams and rivers. This study, therefore, aimed to know the geographical distribution of the M. amazonicum, M. brasiliense and M. jelskii species in the state of Roraima, Brazil. The study area included twelve municipalities in the state of Roraima. The material used in this study was the M. amazonicum, M. brasiliense and M. jelskii specimens deposited in the collection of the Integrated Museum of Roraima-MIRR and the National Institute of Amazonian Research-INPA. The M. brasiliense species originate from scientific expeditions carried out by INPA and MIRR researchers in nine municipalities. Additional shrimp collections. Methods a Freshwater shrimp were collected during the day and night periods, using a 45 × 45 cm wide and 1 mm mesh size collection for hand sampling for hand sampling (puçá); Covo trap; Pet bottle kettle; And a small rectangular trawl. Results 896 individuals of the Pleocyemata suborder of the family Palaemonidae of the genus Macrobrachium were identified, among them the species M. amazonicum, M. brasiliense and M. jelskii. They are distributed in the aquatic ecosystems of plowing and forest in the state of Roraima. The number and geographical distribution of the species M. amazonicum, M. brasiliense and M. jelskii that compose the prawn species of Roraima, corroborated with the proposed study. However, in reference to the intended objective, everything was achieved, promoting the increase of the distribution with respect to freshwater prawns in Roraima.
