Experimental Study on the Cultivation of Bighead Carp in Cement Troughs with Micro-flow Water for Clean Rearing
Abstract：Xiangyin County relies on its unique ecological advantages of the Dongting Lake water area and the extensive aquaculture area, and has long been a major production area for the four major carp species, providing high-quality aquatic protein sources for the local people. In 2024, Xiangyin County's aquatic products reached a total output of 202,860 tons, ranking first in Hunan Province, among which the output of bighead carp reached 17,960 tons. However, under the traditional intensive and high-density breeding model, excessive feeding leads to lipid accumulation in fish, decline in quality, abnormal body shape, loose meat texture, poor taste, and strong earthy smell, resulting in low market prices for commercial fish. How to improve the quality and breeding efficiency of large commodity fish is crucial to the income of the people and rural revitalization. Therefore, the Xiangyin County Aquatic Science Research Institute conducted an experimental study on the clean rearing of bighead carp in cement troughs with micro-flow water, achieving good results, which are summarized as follows.
