MULLER, Yara Maria Rauh  e  CARPES, Simone. Macrobrachium potiuna (Müller): notes on reproductive cycle and it's relations with environmental factors. Rev. Bras. Zool. [online]. 1991, vol.8, n.1-4, pp. 23-30. ISSN 0101-8175.  http://dx.doi.org/10.1590/S0101-81751991000100004.

Researches under field conditions were done on the breeding cycle of Macrobrachium potiuna (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 total length and the total weight of ovigerous females.
