Studies show that there are some freshwater fishes which can survive in brackish and saline waters. Although it is not long that study on the tolerance of fishes against various salinities and effect of salinity on growth rate has been caught up in sclentific fields and that only a few fishes have been subjected to such studies, promising results encouraged us to carry out similar experiments on Barbus sharpeyi from cyprinidae Freshwater Barbus sharpeyi transferred to brackish water with different salinity degrees in three stages as follows : 1) Direct transfer from freshwater to waters of 2, 4, 6, ... , 16, 18 ppt salinity 2 Stepwise transfer to waters of 1, 2 3,...., 17, 18 PPt salinity for tolerance studies. 3) Stepwise transfer to waters with two degrees difference in salinity, for growth rate studies. in this phase freshwater was taken as control. Statistical analysis Computer analysis of acquired data was carried out using t.student and ANOVA statistic, Analyses were signifi.....
