One was due to a stress reaction, and the other was that it was already suffering from some symptoms of oxygen deprivation.

How did this happen?

November 10, 14:30 or so, the missing porpoise was successfully rescued on shore. 17:45, the porpoise in the process of transportation appeared to be a great deal of stress reaction, rescuers gave emergency treatment, but ultimately the porpoise unfortunately died. At present, the porpoise is in Hangzhou Changqiao Polar Ocean Park. Follow-up experts will conduct an autopsy to determine the cause of death. Hangzhou Fisheries Law Enforcement Brigade researcher said that the porpoise usually lives in the confluence of freshwater and seawater, and the preliminary judgment is that the porpoise mistakenly entered the South Campsis Creek.

The porpoise

is a creature that has always lived in brackish and fresh water, and the water quality of Campsis Creek is fresh water. If the porpoise lives in fresh water for a few days without a proper living environment and tasty food, its body will be uncomfortable. When humans transport it to fresh water, they use ropes and iron cages to help them cross the river. The porpoise may have been frightened and had a high production of adrenaline in its body, which induced a stress response in its body. Many biologists have put forward the idea that when humans interfere with the migration of other creatures, the feelings of the creatures must be taken into account. Scientific and effective methods are used to help other organisms on earth to accomplish their migratory activities.

The porpoise had been living in fresh water for several days and was already showing signs of oxygen deprivation and could not withstand any external shock.

The porpoise has always lived in brackish water. This time, it accidentally intruded into fresh water. There is no suitable food for porpoises in fresh water, and it is very dangerous to their health in this environment. After staying in fresh water for a long time, the porpoise will suffer from lack of oxygen.

Stress Reaction

When humans transport porpoises on their way to brackish freshwater with cages, ropes and other tools, the porpoises are frightened, which can seriously lead to the death of the porpoises. Whether at home or abroad, human interference with the migration of other creatures on earth occurs from time to time, and these animals can have a stress reaction. This porpoise, which has a stress reaction and whose body instinctively secretes large amounts of adrenaline, could not withstand the toss and the death rate was high.
