银龙鱼的“哭泣”：不逃离亚马逊河就不能改变“命运”吗

银龙鱼的“哭泣”：不逃离亚马逊河就不能改变“命运”吗

银龙鱼是一种观赏性很强的鱼类。对于水族馆爱好者来说，这并不陌生，尤其是对于富人来说。如果你在家的客厅里放一个鱼缸，在里面养几条银龙鱼，房子的整体布局就会升级

虽然银龙鱼在中国人心中有很高的“地位”，但它被视为富人的“宠物”，在鱼缸里被精心饲养和照顾。但在发源地亚马逊河，银龙鱼就没那么幸运了。它几乎和中国的鲢鱼一样。那么，生活在亚马逊河的银龙鱼怎么了

亚马逊河有什么鱼

亚马逊河流位于南美洲北部，在世界最长的河流中排名第二，但其支流和水量都是世界第一。该河的流量已达到每秒21.9万立方米，是中国长江流量的7倍。在如此巨大的河流水域中，水中生活着许多鱼类。

在亚马逊河中，不仅有鱼类，还有凶猛的两栖动物和爬行动物，包括淡水龟、凯门鳄、巨型海牛和世界上最大的淡水海豚。亚马逊河上栖息着2500多种鱼类，食肉鱼类的数量更是不计其数。可怕的食人鱼是生活在亚马逊河中的巨型鲶鱼，可以长到数百公斤，还有长到6米长的巨型骨舌鱼，其中包括凶猛的鳄雀鳝，它们也混在河中。被中国水族爱好者视为“宝藏”的银龙鱼在这里成为了泛滥物种

亚马逊河银龙鱼

亚马逊河里的银龙，学名双须舌鱼，主要分布于南美洲亚马逊河及其支流。银龙鱼是亚马逊河中的一种大型食肉鱼类。它的正常大小可以长到50-70厘米，最大长度可以长到1.2米以上

银龙鱼的食性分为两个阶段。当体长约10厘米时，通常以小鱼、虾和甲壳类为食，也以水中的昆虫为食；当银龙鱼长大成人后，它不仅会捕食各种鱼类，还会捕食水鼠、青蛙，甚至蜥蜴和蛇

虽然银龙鱼是一种凶猛的食肉鱼类，但它喜欢生活在安静的环境中，尤其是当每年雨季到来时，亚马逊河及其支流的水位上升时。此时，银龙鱼会游入支流，特别喜欢躲在有浮草的环境中，等待伏击路过的猎物

龙鱼的繁殖能力较差。女性和男性需要6至8年才能达到生殖条件。然而，银龙鱼属于繁殖能力强的家族。达到繁殖年龄的雌性银龙鱼每次约有200个卵，这与大多数淡水鱼体外受精相同

然而，银龙鱼的孵化方法与其他鱼类不同。在亚马逊河，当雌鱼排卵时，雄鱼会快速射精，然后将卵含在嘴里，直到“龙鱼宝宝”孵化出来。整个过程大约需要40到50天，雄鱼通常在第二个时期不进食

虽然银龙的性成熟时间很长，卵的数量也很低，但亚马逊河及其支流有茂密的水草和许多死灌木，为银龙鱼提供了良好的繁殖环境，亚马逊河有充足的食物来源，因此，在原产国，银龙鱼的数量与我们的鲢鱼和鳙鱼一样多。然而，生活在亚马逊河的银龙鱼想要逃离。主要原因是亚马逊河可以捕捞。当亚马逊河可以钓鱼的消息传开后，来自世界各地的卢雅爱好者纷纷前来欣赏，而银龙鱼是主要的捕鱼物种之一

此外，虽然银龙鱼具有观赏性，但很少在当地捕获和饲养，通常用作食物。据说，银龙鱼最流行的吃法是烧烤。将捕获的银龙鱼清理干净后，直接放在木炭烤架上烤制，然后在其中加入一些调味料，成为美味佳肴。

另一种吃法是蒸的，但据吃过银龙鱼的人说，这种鱼其实并不好吃，不仅刺很多，而且有点酸。在我们看来，银龙鱼吃起来太贵了。我不得不说这是一件残酷的事情。但事实上，银龙鱼在当地很常见

据去过亚马逊河的游客介绍，只要在亚马逊河流域，随便撒几张网就能钓到几条银龙鱼。事实上，在那里吃饭的人并不多，这与我们的鲤鱼有点相似。银龙鱼生活在中国的高档住宅区和别墅里，而出生在原产国的银龙鱼无法改变被宰杀的命运

因此，银龙鱼“哭了”，表示同一条鱼的生活和同一条鱼生活的差别太大了。如果它能去中国就好了

The "crying" of silver arowana: can't you change the "fate" without escaping the Amazon River

The silver arowana is a kind of highly ornamental fish. It is no stranger to aquarium lovers, especially for the rich. If you put a fish tank in the living room of your home and raise several silver arowana in it, the overall layout of the house will be upgraded

Although the silver arowana has a high "status" in the hearts of the Chinese people, it is regarded as the "pet" of the rich, and is carefully raised and cared for in the fish tank. But in the Amazon River, where it originated, the silver dragon fish is not so lucky. It is almost the same as the silver carp in China. So, what happened to the silver arowana living in the Amazon River

What fish are there in the Amazon River

The Amazon River is located in the north of South America, ranking second in the world's longest river, but its tributaries and water volume are the first in the world. The water flow of the river has reached 219000 cubic meters per second, which is 7 times the flow of the Yangtze River in China. In such a huge river water area, there are many fish species living in the water

In the Amazon River, there are not only fish but also fierce amphibians and reptiles, including freshwater turtles, caimans, giant manatees and the world's largest freshwater dolphins. There are more than 2500 kinds of fish inhabiting the Amazon River, and the number of carnivorous fish is even more numerous

The dreaded piranha is the Amazon giant catfish that lives in the river, can grow to hundreds of kilograms, and the giant bony tongue fish that can grow up to 6 meters in length, including the fierce crocodile finless eel, which is also mixed in the river. The silver dragon fish, which is regarded as "treasure" by Chinese aquarium enthusiasts, has become a flood species here

The silver arowana

silver arowana in the Amazon River, the scientific name of the double whiskered tongue fish, is mainly distributed in the Amazon River and its tributaries in South America. Silver arowana is a large carnivorous fish in the Amazon River. Its normal size can grow to 50-70 cm, and the maximum length can grow more than 1.2 meters

The feeding habits of silver arowana are divided into two stages. When the body length is about 10 cm, it usually feeds on small fish, shrimp and crustaceans, and also feeds on insects in the water; When the silver arowana grows into an adult, it will not only prey on various kinds of fish, but also prey on water mice, frogs, and even lizards and snakes

Although the silver arowana is a fierce predatory fish, it likes to live in a quiet environment, especially when the water level of the Amazon River and its tributaries rises with the arrival of the rainy season every year. At this time, the silver arowana will swim into the tributaries, especially like to hide in the environment with floating grass, waiting for ambush the passing prey

The reproductive ability of arowana is poor. It takes 6 to 8 years for females and males to reach the reproductive conditions. However, silver arowana belongs to the family with strong reproductive ability. The number of female silver arowana reaching reproductive age is about 200 eggs per time, which is the same as most freshwater fish in vitro fertilization

However, the hatching method of silver arowana is different from other fish species. In the Amazon River, when the female fish ovulates, the male fish will ejaculate quickly, and then hold the eggs in the mouth until the "baby arowana" is hatched. The whole process takes about 40 to 50 days, and the male fish usually does not eat during the second period

Although the silver dragon has a long time of sexual maturity and a low number of eggs, the Amazon River and its tributaries have dense water and grass and many dead shrubs, providing a good breeding environment for silver dragon fish, and the Amazon River has sufficient food sources, so the number of silver dragon fish in the country of origin is as large as our silver carp and bighead carp

Why did the silver arowana flee the Amazon River

Arguably, high-grade ornamental fish such as silver arowana are very popular. However, silver arowana living in the Amazon River wants to escape. The main reason is that the Amazon River can be fished and fished. When the news that the Amazon River can fish spread, Luya lovers from all over the world came to admire, and silver dragon fish is one of the main fishing species

In addition, although the silver dragon fish is ornamental, it is rarely caught and raised locally, and is usually used for food. It is said that the most popular way to eat silver arowana is barbecue. After cleaning up the caught silver arowana, put it directly on the charcoal grill to roast, and then put some seasoning into it to become a delicacy

Another way to eat it is steamed, but according to people who have eaten silver arowana, this kind of fish is actually not delicious, it is not only a lot of thorns but also a little sour. It seems to us that the silver dragon fish is so expensive to eat. I can't help but say that it is a cruel thing. But in fact, the silver dragon fish is very common in the local area

According to the tourists who have been to the Amazon River, as long as they are in the Amazon River basin, they can catch several silver dragonfish by scattering a few nets at random. In fact, there are not many people who eat there, which is a little similar to our carp. The silver arowana lives in high-end residential quarters and villas in China, while the silver arowana born in the country of origin cannot change the fate of being slaughtered

Therefore, the silver arowana "cried" and said that the difference between the life of the same fish and the life of the same fish was too big. If only it could go to China
