This study aimed to investigate the feasibility of intensive common carp culture in cemented tanks. The research focused on the growth and production parameters of the fish, the water quality management, and the overall economic feasibility of the system.
The introduction provides a general overview of intensive fish culture and its importance in the global context. It outlines the specific objectives of the study, focusing on the feasibility of intensive common carp culture. The literature review explores existing knowledge on intensive culture, global aquaculture trends, the biology of common carp, water quality management, feeding practices, and nutritional requirements. The materials and methods section details the experimental setup, including the site, tank preparation, stocking density, feeding regime, water quality monitoring, and sampling procedures. The results chapter presents data on water quality parameters, fish growth, production parameters, and economic analysis. The discussion section analyzes the findings in relation to previous research and explores the implications for future aquaculture practices. The conclusion summarizes the key findings and discusses the feasibility of intensive common carp culture in cemented tanks.

It is a high-density fish farming system using cemented tanks or small ponds where fish are fed exclusively on formulated feed under controlled management.
The study achieved a high survival rate of 97.6% for the common carp fingerlings in the cemented tanks.
Key parameters included water temperature (avg. 28-30°C), dissolved oxygen (DO), and pH levels, all of which remained within the suitable range for carp growth.
The fish were stocked at a density of 10 fish per square meter (10 fish/m2) in a 25 m2 cemented tank.
The results, including a net fish yield (NFY) of 30.8 t/ha/year, suggest that intensive farming in cemented tanks is feasible with proper water exchange and feeding management.
