- Experimental study on the efficiency of different types of traps and baits for harvesting Macrobrachium amazonicum (Heller, 1862) Bianca Bentes Jussara Moretto Martinelli-Lemos Eduardo Tavares Paes Suelly Cristina Pereira Fernandes Jeanne Duarte Paula Victoria Isaac Biología Amazon Keywords Guajara Bay North Coast freshwater prawn Macrobrachium amazonicum is a freshwater prawn endemi c to South America with wide distribution in Brazilian Amazon rivers. In estuary and freshwater streams of the Pará State, they are captured with different types of traps locally know ma tapi. This study evaluated the efficiency of traps of different sizes (large, medium and small) and baits (babassu coconut and fish) for sampling this shrimp. Samplings were conducted with 24 tr aps with different treatments (tra p size and bait). We captured 909 specimens. Higher mean catches were observed in trap s baited with babassu coconut. Interactions between babassu coconut bait and medium matapi (BM-M), and fish bait and la rge matapi (FISH-L) were significant. Carapace length (CL) varied signific antly between sites (F = 12.74, p < 0.01). The total maximum length was 13.65 cm. Medium traps baited wi th babassu coconut were the most successful in the tested combinations, however, there was a clear correlation between size trap and size of shrimp, for both body weight and carapace length. 2014 artículo científico 1679-9283 https://www.redalyc.org/articulo.oa?id=187132092002 en http://www.redalyc.org/revista.oa?id=1871 Acta Scientiarum.
