Abstract

Effect of physico-chemical parameters on fish growth in Hanna lake was conducted during March – December 2013. There is no significant (p > 0.05) difference was recorded in the values of temperature, pH, salinity and dissolve oxygen (DO) within sampling sites, but significantly difference was (p> 0.05) noticed in the values of conductivity, transparency, total dissolved solids (TDS) and alkalinity. The values of length –weight relationship of Carrasus auratus and Glypothorax sp. were found to be satisfactory and regression co-efficient (b = 2.10 and 2.0 respectively) indicated as satisfactory growth of two fish species from Hanna lake, Balochistan. The values of relative condition factor (Kn) was calculated for combined sexes for both the fish species (mean Kn = 0.98 and 0.96) in case of C. auratus and Glypothorax sp respectively. It is therefore concluded that the physico-chemical parameters of Hanna lake found to be suitable for the fish growth
