Abstract
A study of chemical and biologicsi aspects (dry weight of planktonic biomass) WAS carried out for a period of one year. The chemical study airned at determination of carbonates. bicarbonates, chlorides. total alkalinity, total' lard nets, calcium, magnesium, nitrates and phosphates. Under biological siudy, the estimation of dry weight of planktonic biomass was roads. The data obtained from chemical analysis and estimation of dry weight of glaaIctonic biomass ware computerised for studying the correlation betwcen the two factors. The correlation betiveen these two Liam was Variable. The contribution of chemical factors towards dry weight of planktonic biomass w11,5 61.2% INTRODUCTION • The production potr:ntial of inland water resources of the Punjab Provi-nce has not been exploited fully due to lack of incentives in terms of scientific andior technical facilities. for development. Fish production from these resources is of great significance because it makes substantial contribution to the supplies of low:cost but nutritionally higli quality animal protein for ever incrassing human population. Fish production is closely correlated with the biological production which in turn depends on the ecological and physico.thernical conditions of water b3dy.

In view of their great importance, the chemical and biological aspects (dry weight of plauktonic biomass) of the water of a pond WCIO studied and the date obtained therefrom w:101 CO711,1LI[eriled to datectriine correIntoin between them.
