Macrobrachium amazonicum is the most commercially-explored fresh water shrimp in the Amazon, finding great acceptance in the consuming market. The objective of this work is to characterize the structure and the ultrastructure of the gonads of different M. amazonicum morfotipos in natural population. The shrimps (500 specimen) were collected in Furo das Marinhas (Mosqueiro – PA), by local fishermen and brought alive to the Laboratório, in an appropriate box containing local water. Fifty males were selected, weight, measured and killed. Gonads were collected and fragments were fixed in 2,5% glutaraldehyde 4% paraformaldehyde in sodium caccodylate buffer at 0,1M pH 7,2. For light microscopy the fragments were processed according to the standar...
