The Yangtze River, the largest river in the mainland, used to be full of fish and shrimp, but with the indiscriminate fishing and environmental changes, many fish populations have plummeted, and some fish have disappeared forever. In January 2020, the Ministry of Agriculture and Rural Affairs issued a notice on the official website on the scope and timing of the fishing ban in key waters of the Yangtze River Basin, announcing the implementation of a ten-year fishing ban plan on the Yangtze River from 0:00 on January 1, 2020.
According to the notice, the natural waters of the main stream and important tributaries of the Yangtze River, except for the aquatic life nature reserve and the aquatic germplasm resources protection area, will be temporarily banned for 10 years from 0:00 on January 1, 2021 at the latest, during which productive fishing of natural fishery resources is prohibited.
With the implementation of the fishing ban, a large number of fishermen have landed, even fishing has regulations, it has been more than 3 years, what is the result of the 3-year fishing ban? I think you can see it from the fish below.
Do you know this fish? It is estimated that many friends know each other because it is so famous. This kind of fish is called cochineal, the appearance is very beautiful, belonging to the order cypriniformes, submouth fish, family cochineal belongs to the wide-temperature freshwater fish. It is also known as yellow rib, roasted bream, red fish, chaffinus and purple bream.
Cochineal is a large middle and lower freshwater fish. It feeds mainly on benthic invertebrates and organic matter in the sediment of the bottom of the water, but also eats some higher plant fragments and algae. It is found in the upper, middle and lower reaches of the Yangtze River in the mainland, and the number of upstream is large; Fujian Minjiang is also produced.
As can be seen from the video, this "little elf" is relatively small, belongs to the juvenile fish, and is gnawing on the algae on the iron chain. The photographer did not disturb the cochineal fish to eat, let alone capture it, which is right, after all, it is a second-class protected animal, and if it is captured, it is a "real punishment"! As soon as this video was released, netizens replied one after another, and some netizens were concerned about what to do if they were caught?
Some netizens replied: "It's easy to tell if this fish is caught"! It is estimated that many anglers have this question, because for anglers, they don't know what kind of fish will be hooked on the next rod, and what if they catch it? Don't even say it, a fishing friend actually caught a fish.
A few days ago, a lure angler released a video to catch a cochineal, that one is relatively large, estimated to weigh a few pounds, this angler was afraid of hurting it, did not touch it, did not let it out of the water, in the water with lure tongs hook release, this is the best way.
Don't take it home after catching it, make the mistake and then take it home, if you take it home to eat, or intentionally hurt, it is a "real punishment", and you must be legally responsible for catching or maliciously injuring second-class protected animals.
Some netizens replied: "This thing especially likes to gnaw moss." This netizen probably has an understanding of cochineal, which feeds on benthic invertebrates and organic matter in the bottom mud, as mentioned earlier, and also eats some higher plant fragments and algae. This fish does like to eat algae, and the fish is shown in the video gnawing on algae on a chain.
One conclusion can be drawn from this video, that is, the Yangtze River is ahead of the fishing ban, and fish resources have been slowly recovering. Cochineal is sexually mature very late, with males over 5 years old and females over 7 years old. Sexually mature cochineal begin to migrate reproductively in mid-February each year.
The spawning grounds of the Yangtze River are in Jinsha River, Minjiang River, Jialing River and other places. The breeding season is from early March to late April. Spawning begins when the water temperature stabilizes above 13°C. After spawning, the broodstock remain in the vicinity of the spawning grounds until the late autumn when the water recedes, when they return to the deep waters of the main stream for wintering.
This cochineal should be a 1-year-old juvenile, that is to say, the cochineal has begun to reproduce naturally, this 1-year-old juvenile can reproduce naturally after 5-6 years of growth, which is equivalent to saying that when the fishing ban is 10 years, it can reproduce 2 generations, which is very beneficial to the population protection of cochineal.
Finally: fishing in the Yangtze River, fishing should be carried out according to local regulations, do not fish in the reserve, strictly abide by the method of one rod and one hook, and must not take back the protected fish after catching, so as not to violate the criminal law.
