Abstract
The salinity preferences of the larvae of 5 indigenous species of Macr obrachium namely M. lepidactylus, M. rude, M. petersi, M. scabriculum and M. australe was investigated. Results showed that saline condition s are definitely required for the survival and development of the earl y larval stages. Survival and morphological development of the larvae of all 5 species studied improved markedly once the salinity of the me dium used was increased to levels exceeding 5 S parts per thousand wit h the most satisfactory levels being above 10 S parts per thousand.
