Abstract

The pH, EC, K⁺, Ca²⁺, Mg²⁺, Na⁺, CP, CO₃²^- and HCO₃^- were analyzed for water from different ghers in Fakirhat, Southwest of Bangladesh to profile out their suitability in shrimp farming. The range of pH was 8.35 to 8.62, EC was 4.75 to 6.80 dSm^-1, Na⁺ was 15.06 to 19.35 meqL^-1, K⁺ was 0.81 to 0.90 meqL^-1, Ca²⁺ was 32.71 to 35.37 meqL^-1, Mg²⁺ was 4.73 to 5.66 meqL^-1, CP was 142.0 to 188.5 meqL^-1, CO₃²' was 45 to 75 meqL^-1 and HCO₃^- was 0.20 to 0.40 meq^-1 and it was concluded that the concentration of K⁺, Ca²⁺, Mg²⁺ and the pH levels of the investigated ghers were suitable for shrimp farming. However, the levels of Na⁺, CP, CO₃²^- and HCO₃" exceeded the standard levels and restricted shrimp farming. The results were statistically significant except for CP and HC0₃^-.
