dc.description.abstractThe salinity tolerance of freshwater-spawned and reared Oreochromis mossambicus, O. niloticus and their F1 hybrids of various ages was studied. Several tests were conducted using three indices as practical measures of salinity tolerance: (1) mean survival time (MST); (2) median survival time (ST50); and (3) median lethal salinity-96 hours (MLS-96). Interspecific and age-specific differences (P<0.01) in salinity tolerance were observed in these species and their F1 hybrids on the basis of MST and ST50 indices, with salinity tolerance generally increasing with age of brood. No significant age-specific differences (P > 0.05) in salinity tolerance were observed in all four groups on the basis of MLS-96 index. At the same salinity O. niloticus fry at ages from 15 to 90 days post-hatch exhibited significantly lower (P<0.05) salinity tolerance than O. mossambicus and F1 hybrids. Changes in salinity tolerance were determined to be more closely related to body size than age.en
