The species Macrobrachuim amazonicum is abundant in the Amazon river basin and broadly explored by artisanal fisheries in the State of Para. It is also used in extensive culture in this region and in the Northeast of Brazil. The purpose of this paper is to analyze bioecological aspects of the species, offering subsidies for is appropriate management. Monthly samples were accomplished in the municipal district of Vigia, during the years from 1999 to 2001 and the obtained data were analyzed considering the rainy season (January to June) and the less rainy season (July to December). During the period of study the temperature oscillated between 26 to 30°C and the salinity between 0 and 28%, even so the medium value classifies the environment as oligoaline. The species was present in all the samplings, even so it was more abundant in the rainy period. Males and females were caught in all the samplings, even so the males were more abundant in a proportion of 2,5:1. The ovigerous females were more representative in the rainy period. The species presents continuous reproduction with more intense periods in the months of February, May and June, in the rainy season, and September, in the less rainy season. The males presented lengths higher than the females. The smallest individual caught measured 1,7 cm and the largest 14,4 cm. The smallest ovigerous female collected measured 3,5 cm and the largest 11,6 cm. Cohorts were observed the months of February, April and May, in the rainy season, and July, August and September, in the less rainy season, characterizing the occurrence of spawn and recruitment. The relationship total weight / total length presented sexual dimorphism, in all the years. For the first year it was obtained the following relationships: males - WT = 0,0104 LT2,8208 and females - WT = 0,0068 LT3,0619; for the second: males - WT = 0,0098 LT2,8766 and females - WT = 0,0061 LT3,1494; and for the third: males - WT = 0,0072 LT2,9224 and females - WT = 0,0072 LT2,9726. The species presented an alometric growth. The abdomen is the largest segment of the body, representing about 56% of the total length. The length of the carapace presented little difference among the sexes. The females presented the abdomen a little heavier than the males. The weight of the abdomen can be expressed by the equations WAB = 0,5397 WT (males) and WAB = 0,5619 (females). In the males the carapace is heavier than in the females and are expressed, respectively, by the equations: WCT = 0,4503 WT and WCT = 0,4381 WT.
