Cold fishing is one of the main killers of freshwater fish resources, which not only reduces the "stock" of fishery resources, but also seriously damages the "increment". Why do baiji, finless porpoise and paddlefish become large-scale rare and protected animals? In addition to the damage caused by illegal fishing methods and ship propellers, the important reason for the disappearance or sharp decline of these animals is the sharp decline in the number of fish. The Yangtze River "has no fish", and the most direct harm is these large animals at the top of the food chain pyramid. If measures are not taken or disappear after 15 years, it is related to the development and future of freshwater aquaculture to preserve the natural germplasm resource pool of the Yangtze River and restore the natural ecosystem of wild fish in the Yangtze River.

Previously, the Yangtze River has set a three-month fishing ban every year. Why do you want to ban fishing for ten years this time? In this regard, relevant experts explained that it generally takes four years for the four major fish to reproduce and grow. Only when the fishing ban is set at ten years, can they reproduce for two or three generations, so that their numbers will recover, their individuals will become bigger and bigger, and they will produce good quality fish. In the past three months, there were not enough fish to catch for three days. Will there be a shortage of aquatic products after ten years of fishing ban?

In fact, most of the water products we need every day come from artificial farming, not natural fishing in the Yangtze River basin. According to the data, the natural catch in the main stream of the Yangtze River only accounts for 0. 15% of the total aquatic products exceeding 60 million tons per year in China. In other words, the ban on fishing in the Yangtze River basin has little impact on the supply of aquatic products.

Let the Yangtze River breathe, is responsible for the Yangtze River, responsible for the people along the Yangtze River, responsible for future generations. It is also expected that the Yangtze River will be clean and beautiful and the ecology will be completely improved after ten years.
