The finless porpoise is familiar to everyone, this kind of mammal, the appearance looks simple and fat, but it is very flexible, once distributed in the mainland is very wide, the middle and lower reaches of the Yangtze River, Dongting Lake, Poyang Lake and other places.
In the 80s of the last century, the number of baiji dolphins in the Yangtze River was about 300, and the number of finless porpoises was about 3,000, after which the number of baiji dolphins and finless porpoises dropped significantly, and by the end of the 20th century, the number of baiji dolphins observed was only more than 10, and the number of finless porpoises was less than 2,000.
In 2006, a delegation of more than 40 Chinese and foreign experts conducted a carpet search in the Yangtze River, but found no trace of a baiji dolphin, and in 2007 the finless porpoise was declared functionally extinct! At this time, the number of finless porpoises is further declining!
In 2017, only 1,012 finless porpoises were found in the scientific expedition! There is an urgent need to protect the finless porpoise, and although the finless porpoise has been upgraded to a first-class protected animal, the decline of the finless porpoise's population cannot be reversed by upgrading alone.
Due to the serious deterioration of the ecological environment in the Yangtze River basin, not only the fish population is younger, and indiscriminate fishing has become the norm, the last resort is to ban fishing for ten years, and increase the publicity of the importance of protecting wild animals, with the cooperation of various measures, the results are gratifying, not only the fish species are slowly recovering, but the density of the finless porpoise is also slowly increasing.
On February 28, 2023, the Ministry of Agriculture and Rural Affairs announced the latest scientific research data: the natural population of the Yangtze finless porpoise is 1,249, and it has stopped falling and rebounded! The result is encouraging, with only two years of fishing banned, and nature is very resilient with less human disturbance.
And yet some people are still breaking the law! "Nanyang Daily" reported on September 12, with the headline: "It turns out that every finless porpoise has chips on it"! In the video, a fishing friend has just caught a finless porpoise while fishing, but law enforcement officers arrive later.
After the on-site law enforcement officers arrived, the angler was still quibbling, but he would not be given a chance at all, the fishing man in the video was taken away on the spot, and other fishing friends were still wondering, so many anglers, how to target him, after the release of this video, many netizens replied.
Some netizens replied: "Some finless porpoises have built-in chips, and they will call the police, don't you know"? It's also the first time I've heard that finless porpoises will call the police! The principle should be very simple, that is, abnormal alarm!
For example, since 2014, Poyang Lake, the largest finless porpoise germplasm bank in mainland China, has relocated 16 finless porpoises to Hubei, Hunan, Anhui and other places in two batches to supplement the populations of these three ex-situ reserves and optimize their population genetic structure.
On March 13, 2015, researchers transported the Yangtze finless porpoise to Hubei in Poyang Lake, Jiangxi Province, to optimize the genetic structure of its population. When these finless porpoises are transferred, they spend a lot of manpower and material resources, and it is relatively normal to install chips, which monitor the status of the finless porpoise at all times, and will automatically alarm once there is an abnormality.
Some netizens replied: "He must have caught it and put it in the fishing net, so the conservation center over there found that the finless porpoise had not moved in this position, so it was useless for him to quibble."
This netizen is right, if you release the fish immediately after catching, it is a mistake to fish, if you don't release the fish but use a rope to tie it to the river, or it is directly placed in the fish protection, this nature will change!
When the finless porpoise equipped with the chip does not move for a long time, or the heartbeat is abnormal, or the chip is set to other abnormal states of automatic alarm, in this case, it will definitely be fed back to the monitoring host, so as to be discovered by law enforcement officers.
When the law enforcement officers found that the finless porpoise was abnormal, they would immediately locate the abnormal location and rush to the location, and the angler who caught the finless porpoise became a live target and was immediately found on the spot.
In the end: after the man caught the finless porpoise, the law enforcement officers arrived on the back foot, and he also quibbled and was taken away on the spot! This is an example for anglers in the Yangtze River, as well as those who fish illegally, who catch protected fish and release them immediately, and those who are still fishing against the wind will definitely be caught, and everyone has a responsibility to protect the finless porpoise and the ecological environment in the Yangtze River.
