In recent years, with the rise of humanitarianism in the world, the word "release" has gradually emerged in human society, and for those creatures that have long been raised by humans and lost their freedom, some religious or animal groups have advocated that "these creatures should be returned to the embrace of nature" and that "freedom should not belong only to human beings, but the beauty that all living things should experience." But surprisingly, these seemingly benign claims sound like hellish death knells to many biologists, and of course there are some exaggerations to say, but you know that the consequences of release will not only affect the environment, but even put humans in danger. What's going on here? Today I will introduce you to a creature, the lionfish.
I think if you have been to the aquarium or aquarium friends have seen this fish, the vast majority of people should have the impression of them should be poisonous, if they are stabbed by its thorns, although they will not die, but it will be better to live than to die. Also did you know that this creature is actually a delicacy? It is not only a delicacy, but even in some countries, the government has openly asked the people to eat more and encouraged them to eat.
It turns out that the lionfish is not only a beautiful ornamental fish, but also a creature with super vitality and eating ability, in an aquarium in Florida, the United States, because of a hurricane, caused six lionfish in the museum to escape into Iskan Bay in Miami, and since then the most serious lionfish disaster in the history of Florida waters has been launched, and it is because of these six lionfish that the United States has caused incalculable losses.
Because of the amazing reproductive ability of this creature, laying eggs once every four days, up to 30,000 eggs at a time, these creatures originally inhabited the Indian Ocean region, there are all kinds of natural enemies and predators to stop this creature's way to becoming king, but since this creature because of the release of the breeder and an unexpected hurricane invaded the Mediterranean and American waters, the lionfish's way to becoming king no longer has those natural enemies as a stumbling block, they began to grow as much as they wanted, and they ate as much as they wanted.
The terrible thing is that the lionfish eat and you imagine that the food may not be the same, they are the super big stomach king in the fish, the amount of food is very large, and not picky eating, the amount of food eaten every day can reach 90% of its own weight, it is not picky eaters, it has more than 100 kinds of fish in its recipe, once some scholars found after dissecting the lionfish, there are 50 small fish in the stomach, so where they go for other fish, it is simply an alien invasion of the earth, it is a disaster. In Florida, for example, the rapid increase in lionfish has led to a 65% drop in local fish populations, which is really scary.
This is not the most exaggerated, this creature may be because the fish in the invading area are eaten by their own companions, and more and more of their own kind, even began to swallow the same kind, for them, eating is the most important thing in the fish life, so the government that was invaded by this creature began to think, how to limit the growth of this creature? In addition to encouraging fishermen to catch more lionfish, the most commonly used by the government is to ask people to eat lionfish in large quantities, how much can be eaten, but this seems to be not enough, the United States in order to curb the lionfish these arrogant guys, and even used biological weapons, sharks. They specially trained sharks and various large fish to kill lionfish, and let these biological weapons kill in the location of lionfish, which slightly controlled this serious ecological crisis.
Speaking of which, I think that in our country, it should not be so widespread!
