Common carp (Cyprinus carpio) is a hardy and resilient freshwater fish capable of surviving in a wide range of environmental conditions. It tolerates variations in temperature, dissolved oxygen, and water quality better than most cultured species. This adaptability allows it to thrive in ponds, lakes, reservoirs, and even moderately polluted waters. The present study was conducted in fish pond of Govt. Degree College, Baramulla to investigate the optimization of rearing and reproductive conditions of Cyprinus carpio (common carp) under a semi-intensive farming system. The research aimed to assess the growth performance, and breeding efficiency through balanced pond management, feed optimization, and controlled water quality. Experimental trials were conducted in a pond with a semi-concrete pond with earthen bottom and concrete sidewalls over a twelve-month culture cycle. Water temperature, dissolved oxygen, and nutrient load were monitored regularly. Broodfish were conditioned using formulated diets with 30% crude protein, and natural breeding was carried out by designing a suitable breeding facility and maintaining optimum environmental conditions to promote natural spawning of Cyprinus carpio in captivity. Results revealed that optimum growth and reproductive performance occurred in well maintained semi-intensive system.
