Abstract.Macrobrachium vollenhovenii(Herklots), the largest freshwater shrimp in West Africa, has been selected for culture in Nigeria. The oxygen uptake, metabolic rates and energy of inetabolism were investigated by known respiratory method in salinities of 0, 7, 15 and 20ppt. There were no significant differences in response to various salinities. This supposes similar physiological response to oxygen consumption with changes in salinity between 0 and 20ppt. These results are also discussed in relation to the culture conditions for the species.
