European eel
The European eel is a fish belonging to the family of Anguillans and currently holds the category CR which indicates that it is an animal in critical danger of extinction according to the listing of the red list of animals in extinction made by IUCN . Next we will analyze some interesting aspects related to this eel that is also called common eel.
GENERAL CHARACTERISTICS OF THE EUROPEAN EAGLE
The European eel has different lengths, although to date, the record has a copy that reached 133 cm. The weight of the same was 6.6 kg and in terms of age, the record was obtained by another copy that reached 88 years.
The European eel is in serious danger of extinction, but even so it remains a fish of great commercial importance especially the angula. For those who do not know the difference, the eel is the animal when it has reached adulthood, while the eel is the moment in which they are maturing, that is, when they remain in the rivers and have not yet been directed back to the sea.
When they are caught at this moment, reproduction is difficult, since they can not return to the sea and mature sexually.
However, at the present time it has been fundamentally chosen to breed this animal species in fish farms, thus favoring nature to continue its course without interruption.
Another threat was on the part of the attempt to introduce Japanese eels in European seas, which extinguished a nematode that affects European eels destroying a good part of their reproductive tissue, which spoils their swim bladder and hinders reproduction .
Plastics are also elements that increasingly make the European eel permanently more difficult due to the ingestion by the larvae of plastic particles, which leads to the appearance of an intestinal obstruction dying shortly afterwards.
According to the statistics of IUCN, in the last 60 years the species has been reduced by approximately 80%, which represents a significant risk and can end with the complete disappearance in the natural environment.
