Correlation of planktonic biomass with other physico-chemical parameters of water quality in fertilized fish ponds

The production of common carp (Cyprinus carpio) was studied in pond fertilized with cow-dung @ 0.1g N/10g in the presence of planktonic biomass. The correlation of planktonic biomass with water quality physicochemical parameters of three fish ponds, was studied. The parameters such as pH, temperature, dissolved oxygen, total alkalinity, total dissolved solids, total hardness, magnesium, calcium, light penetration, total solids, carbonates and bicarbonates, were analyzed in a laboratory using standard protocols. Data collected at the end of the present experimental study was subjected to an appropriate statistical analysis to appraise the correlation coefficients of planktonic biomass with several physicochemical parameters of three ponds under study. In most cases significant correlations were recorded between biomass and key physico-chemical attributes of the ponds.
