Mc. Cort et Hj. Schoonbee, INVESTIGATIONS INTO THE SALINITY PREFERENCES OF SUCCESSIVE LARVAL DEVELOPMENTAL FORMS OF 5 INDIGENOUS SPECIES OF THE FRESH-WATER PRAWN MACROBRACHIUM, Water S.A., 19(2), 1993, pp. 153-162
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.
