Previously McElwee et al. (2002) had reported faster growth of tilapia (Oreochromis shiranus chilwae, O. shiranus chilwae and O. karongae) in 10‰ salinity water declaring it a potential candidate for brackish water aquaculture. Previous studies support ours and confirm that higher salinities are quite favorable for the growth of

Correlation of conductivity with
pH, weight and length was found positive and significant.
DO showed positive and non-significant correlation with
pH, negatively significant with weight while negative and
non-significant with fish length (Table 3). Lei (2002)
reported that oxygen consumption in Oreochromis
niloticus and O. mossambicus varied significantly with
varying levels of salinity. El- Sherif and El-Feky (2009)
observed that water pH 7-8 could be more suitable for
tilapia culture for optimum growth performance and
survival rate. The present study also revealed that pH has
significant effect on the growth of Nile tilapia
(Oreochromis niloticus) (Table 3). O. niloticus is more moderate in its tolerance to saline conditions and dies at
salinities >20,000 ppm (Kirk, 1972). Our results indicate
that O. niloticus can survive and grow well at salinities
up to 4000 ppm may be it can grow higher at higher
salinities but it was not tested in current studies.
