美国金鱼肥如足球，水中几乎没有天敌。当地人：别再让它过去了

我们很多人都在家里养金鱼。金鱼是一种观赏鱼，非常美丽。它们不太大，看起来很有趣

然而，这种在我们眼中很常见的宠物金鱼现在对美国的生态环境构成了威胁。报道称，在美国明尼苏达州的湖中，有重达4公斤的金鱼，看起来像足球大小。可以说这已经足够惊人了

美国宠物金鱼和足球一样大

在美国，宠物金鱼也是一种外来物种。我们都知道，一些研究认为金鱼的祖先是鲫鱼，鲫鱼是由几代人的人工繁殖进化而来的，这也表明金鱼本身不是美国物种。起初，它只在亚洲流行，然后随着人类的活动，它开始走向世界其他地区。

根据数据，宠物金鱼自20世纪80年代以来首次在佛罗里达州发布。后来，它们在美国许多地区的数量一直在增加。今天，生态环境受到了威胁。目前，宠物金鱼经常被放生，这也使得生态恶化更加严重。

目前，为了处理湖中的这些巨型金鱼，明尼苏达州计划投资15万美元对它们进行清理和翻新。然而，在美国，仍然有人购买宠物金鱼，然后养一段时间，如果他们觉得无聊，就会被释放。因为宠物金鱼和其他入侵美国的鱼类一样，没有天敌，适应性强，繁殖和泛滥的速度非常快

也许在未来，这也将是治理上的难题。毕竟，亚洲鲤鱼入侵美国这么多年，在治理方面仍然没有取得任何明显成果。作为过去的警告，宠物金鱼的命运也可以想象

The American goldfish is as fat as a football, and there are almost no natural enemies in the water. Local: Don't let it go again

Many of us raise goldfish in our homes. As an ornamental fish, goldfish are very beautiful. They are not too big and look very interesting

However, this kind of pet goldfish, which is very common in our eyes, now poses a threat to the ecological environment of the United States. According to the report, in the lake of Minnesota in the United States, there are goldfish weighing up to 4 kg, which looks like the size of a football. It can be said that it is amazing enough

American pet goldfish is as big as football

In the United States, pet goldfish is also an exotic species. We all know that some studies believe that the ancestor of goldfish is crucian carp, which evolved from generations of artificial breeding, which also shows that goldfish itself is not an American species. At first, it was only popular in Asia, and then with human activities, it began to go to other parts of the world

According to the data, pet goldfish were first released in Florida since the 1980s. Later, their number in many parts of the United States has been increasing. Today, there have been threats to the ecological environment. At present, pet goldfish are often released, which also makes the ecological deterioration more serious

At present, in order to deal with these giant goldfish in the lake, Minnesota has planned to invest 150000 US dollars to clean up and renovate them. However, in the United States, there are still people who buy pet goldfish and then keep them for a while and they will be released if they feel bored. Because pet goldfish, like other fish invading the United States, have no natural enemies and have strong adaptability, The speed of breeding and flooding is very fast

Perhaps in the future, it will also be a difficult problem in governance. After all, Asian carp have invaded the United States for so many years, and still have not achieved any obvious results in governance. As a warning from the past, the fate of pet goldfish can also be imagined
