Resistência de Macrobrachium holthuium Genofre & Lobão, 1976 e Macrobrachium iheringi Ortmann, 1897, í­Â variação de salinidade em função dos estádios do ciclo de intermuda

Abstract

This paper tries to determine the resistance of Macrobrachium holthuisi and Maerobraehium iheringi among variations of salinity, relative to intermoulting cycle. The characters considered were body weight variations and mortality rate after one hour stayed in sea water dilutions. The data showed had been related .between the resistance of salinity variations in Maerobrachium holthuisi and Maerobraehium iheringi and intermoulting cycle. Stadium AB was more sensitive than the stadia C and D.
