Macrobrachium potiuna (Müller): aspectos do ciclo reprodutivo e sua relação com parâmetros ambientais (Crustacea, Decapoda, Palaemonidae)

Abstract

Researches under field conditions were done on the breeding cycle of Macrobrachium potluna (Müller, 1880), a freshwater shrimp from southern Brazil. It was possible to determine the fecundity and establish its relations with the spawn's weight, the totallength and the total weight of ovigerous females. KEY WORDS.
