Mackerel is a unique fish species in Qiupu River, with fine scales and tender meat, a small black head, a white tail and a red belly, weighing about one catty. It is a rare fish in Qiupu River.
Qiupu River, located in the hinterland of Guniujiang, Anhui Province, is a national ecological demonstration area. Small river fish grow in high-altitude mountain spring water. Because the river water is too clear, the temperature is low, and the fish grows slowly, and the natural bait is completely absorbed in the long growth process, and the nutrients such as protein and minerals are much higher than those of cultured fish.
