Polyculture techniques for enhanced productivity in ponds

Abstract:

Fish polyculture represents a biologically efficient and economically sustainable approach for improving pond productivity. The system involves culturing multiple compatible fish species that utilize different ecological niches and food resources within the same water body. This technique ensures optimum utilization of available natural feed and space, thereby enhancing total yield without adversely affecting the environment. Proper species selection, pond preparation, water quality management and feeding strategies are crucial for successful implementation. Indian and Chinese carp-based polyculture systems have demonstrated significant success in tropical and subtropical regions. Integrating fish with other farm components such as ducks, poultry or rice further improves nutrient cycling and farm productivity. This article examines the principles, species combinations, ecological interactions, management practices, advantages and challenges of polyculture in ponds, highlighting its importance in sustainable aquaculture development.
