Comprehensive Analysis on the Metabolic Activity of the Fresh Water Fishes such as Labeo rohita and Catla catla

Sustainable aquaculture has become increasingly important in meeting global food demands while minimizing environmental impact. Integrated farming systems, which combine multiple compatible species, offer a promising approach to achieve this goal by optimizing resource use and improving overall productivity. This study provides a comparative analysis of two major freshwater carps, Labeo rohita (Rohu) and Catla catla (Catla), within an integrated farming framework. The research evaluates their growth performance, feed conversion efficiency, and tolerance to varying stocking densities, which are critical parameters for sustainable culture practices. Rohu, with its omnivorous and herbivorous tendencies, efficiently converts plant- based feed and natural pond productivity into biomass, making it highly adaptable to polyculture systems. Catla, a surface- feeding species with a preference for protein-rich zooplankton, shows rapid growth under optimal feeding conditions but requires more space and water quality management to thrive. When cultured together, these species complement each other’s ecological niches, ensuring more efficient feed utilization, reducing competition, and enhancing overall biomass production. The study highlights that integrating Rohu and Catla in aquaculture systems not only maximizes yield but also promotes ecological balance and resource sustainability, making it a viable strategy for long-term, environmentally responsible freshwater fish farming.
