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) differencewas recorded in the values oftemperature,pH, salinity anddissolve oxygen (DO) within sampling sites, but significantlydifference was (p> 0.05) noticed in the values ofconductivity, transparency,total dissolved solids(TDS) and alkalinity. The values of length–weight relationship ofCarrasus auratusandGlypothorax sp.were found to be satisfactory and regression co-efficient (b = 2.10 and 2.orespectively) indicated as satisfactory growthof two fish species from Hanna lake, Balochistan.The values of relative condition factor (Kn) was calculated for combined sexes for both the fishspecies (mean Kn = 0.98 and 0.96) in case ofC. auratusandGlypothorax sprespectively. It istherefore concluded that the physico-chemical parameters of Hanna lake found to be suitable forthe fish growth
