Fecundity of Macrobrachium acanthurus Wiegmann, 1836 (Decapoda: Palaemonidae) in a tropical coastal lagoon subject to human impact (Macaé, Brazil)

Abstract

This work was performed at Imboassica lagoon (Macaé, RJ), an urban coastal lagoon subject to anthropogenic impacts, such as the inflow of untreated domestic sewage, landfilling in its margins and artificial openings of the sandbar that separates it from the ocean. Many studies have been done in this lagoon to develop a management plane to it. This research almed to evaluate the sandbar openings effects on Macrobrachium acanthurus after frequents events os breaching, through its fecundity and ovigerous famales density.
