Basic Introduction of Nanwan Lake Culter Fish

Mianhe Nanwan Lake Culter Fish is a specialty of the Mianhe River in Xinyang and a national geographical indication product.

Culter grows rapidly, is coarse and raised, has a large body size, with the largest individual weighing over 8 kilograms. Common wild individuals weigh 50-3 kilograms. Artificially cultivated fish fry can reach 0.6-1 kilograms per year and 2-3 kilograms per year. Generally speaking, during the seedling stage to a weight of 100 grams, growth is slower, 100-200 grams grow slightly faster, 200-300 grams grow faster, 300-2500 grams grow the fastest, and above 3000 grams, the growth rate gradually decreases. The growth rate of the same batch of red carp seedlings is relatively consistent. Male and female fish feed year-round (including severe winter season), with little individual difference. Female fish also feed normally during the breeding season, and their growth rate will not slow down due to reproduction

The reason why Nanwan fish can be praised by everyone is also due to its superior natural environment and natural breeding methods. Nanwan fish never feed any artificial feed and start releasing fish fry every November. After at least two years of wild growth, don't think that these net boxes are used for fish farming, because it's not the season for large-scale fishing. The fish are only temporarily stored here waiting for market sales, and they need to reach a size of more than 5 pounds. Nanwan Lake has also passed the certification of a pollution-free aquatic product production base, with a total aquaculture area of 71000 acres. Most of the water bodies are managed and operated by the local aquaculture department, and some lake branches are contracted to surrounding farmers for fish farming
