At present, the biological integrity index of the Yangtze River has reached the worst? No fish? Level, so it is extremely urgent to realize the ban on fishing and let the Yangtze River recuperate.
Recently, the Ministry of Agriculture and Rural Affairs issued an announcement in official website, announcing that the ten-year fishing ban plan for the Yangtze River will be implemented from June 5438+ 10/day, 2020.
Unlike the previous annual spring fishing ban, this 10-year fishing ban is unprecedented. Facing the Yangtze River? No fish? Predicament and ecological deterioration, the fishing ban period of 10 is a century-old plan to protect the Yangtze River.
The ten-year fishing ban not only saved the fish, but also saved the living environment.
The Yangtze River flowing down from the Qinghai-Tibet Plateau is the mother river of the Chinese nation, the largest river in China and one of the rivers with the richest aquatic life in the world.
From Qinghai to Shanghai, it flows through 1 1 provinces and cities, and then flows into the East China Sea from Chongming Island, which is full of vitality. However, in recent years, the deteriorating ecological situation in the Yangtze River basin has become a big problem.
As we all know, cold fishing is the main reason for the sharp decline of freshwater fish resources? Black boy? 1. Can't we just cut fishery resources? Stock? And badly damaged? Increment? .
Why are there baiji, finless porpoise and white sturgeon? Have 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.
Yangtze River? No fish? The most direct harm is these large animals at the top of the food chain pyramid. If no measures are taken, or disappear after 15 years.
Therefore, protecting the natural germplasm resources of the Yangtze River and restoring the natural ecosystem of wild fish in the Yangtze River are related to the development and future of freshwater aquaculture.
One of the most important and direct factors for the decline of aquatic biological resources in the Yangtze River Basin is the overfishing of cool fish.
Some fishermen abuse it in order to get fishing income? Electric poisoning? 、? Homeless network? And other illegal operations, not only catch big fish, but also let go of small fry, resulting in? The less resources are fished, the worse the ecology is and the poorer the fishermen are? A vicious circle.
Some netizens living in the upper reaches of the Yangtze River wrote,? You can hear the motor of fishing boats from midnight to early morning at night? .
Why does the Yangtze River set a ten-year fishing ban every year, and the fishing ban is three months, so 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.
