Statistical Modeling of Inter-Relationships Between Limnological Parameters in Urban Pond Ecosystems of Bhagalpur, India

This study investigates the complex inter-relationships between 18 physicochemical parameters in two urban ponds, Sahjangi and Bhairwa, in Bhagalpur, Bihar. Utilizing Pearson correlation coefficients, the research identifies critical drivers of aquatic health. Key findings include a strong negative correlation between water temperature and dissolved oxygen (-0.738) and significant relationships between nutrient levels and primary productivity. These findings provide a statistical basis for managing urban aquaculture systems under varying seasonal stresses.
