Salinity

(%o) Comments Source

S. aureus

Grew and reproduced in brackishwater

ponds

Growth was nearly equal to that in

freshwater ponds; greater mortalities

in brackishwater

Reproduced in brackishwater

Survived direct transfer from freshwater

Grew well; failed to reproduce

Able to survive through gradual

adaptation

S. galilaeus

Thrived and bred naturally

Thrived and grew after direct transfer

from freshwater

S. mossambicus

Grew well and reproduced in ponds

No reproduction

Reproduced

Reproduced

Thrived and reproduced; survived

better than S. aureus and S. niloticus

Maximum salinity tolerated after

direct transfer from freshwater

Was able to tolerate this through

gradual adaptation

Acclimated to'this salinity; Grew

better than S. aureus; Did not

reproduce

Found in the Red Sea

Found in the hypersaline Bardawil

Lagoon
