金鱼头部下沉与体型的关系分析

金鱼（细节）

金鱼头部下沉实际上与鱼的体型有关。一般来说，身材矮小或头部较大的人容易出现头部下沉症状，但也有身材矮小的人不会摔倒的情况。两者之间的关系是什么？1.金鱼由鲫鱼人工培育而成。在养殖过程中，由于人们的审美偏好，保留了短粗圆润的金鱼。在这个过程中，形状的进化速度比鱼内脏的进化速度快得多。让我们想象一下，一条食用鲫鱼的内脏被塞进金鱼的胃中，鱼鳔等器官的位置需要改变，它无法达到野生鲫鱼在自然环境中进化的平衡点。因此，与野生鲫鱼体型差异较大的金鱼（如短尾镀金）更容易种植头部。相反，变化较小的草金种植它们的机会要小得多！2、也是在喂鱼的过程中，为了让金鱼长得又肥又美，人们大量喂食饲料，导致鱼肚子里大量脂肪堆积，体内脂肪增加。除了使鱼的肚子变大之外，它还占据了体内其他器官的位置，导致金鱼从小到大，并逐渐低头（所以有些金鱼停止进食会好起来，如果喂食会低头）；3、以上两点表明，即使是健康的金鱼，也是一个正在适应平衡的个体，并不十分不稳定。因此，当金鱼遇到外部环境的突然变化（水温突然下降等）和饲料（从新鲜到膨化）时，它也有头部下降的风险；4.以上都是关于在金鱼的身体和身体刺激的情况下，有可能发生掉头的危险，但有另一种说法，从病理学的角度来看，金鱼的身体平衡取决于靠近鳃盖后部的一个叫做“耳石”的器官，它就像人类的小脑，通过它可以控制每个鱼鳔的空气流入和流出以及每个鳍的滑动。如果耳石被细菌或病毒感染，很容易摔倒。不过，如果听说这种情况，我可以用煮过的绿豆花喂鱼，可以起到排毒的作用，让金鱼得到缓解

Analysis of the relationship between goldfish's head sinking and body shape

Goldfish (details)

Goldfish's head sinking is actually related to the body shape of the fish. Generally, people with short body or big head are prone to suffer from head sinking symptoms, but there are also cases where people with short body do not fall. What is the relationship between the two? 1. Goldfish are artificially cultivated from crucian carp. In the process of cultivation, because of people's aesthetic preference, the short, thick and round goldfish are retained. In this process, the evolution speed of the shape is much faster than the evolution speed of the fish's viscera. Let's imagine that the viscera of a food crucian carp is stuffed in the stomach of the goldfish, and the position of organs such as the swim bladder is necessary to change, It can't reach the balance point of wild crucian carp's evolution in the natural environment. Therefore, goldfish (such as gilding with short tail) with larger body size difference from wild crucian carp are more likely to plant their heads. On the contrary, grass gold with smaller change has a much smaller chance of planting their heads! 2. It is also in the process of feeding, in order to make the goldfish fat and beautiful, people feed a large amount of feed, resulting in a lot of fat accumulation in the belly of the fish, and the increase of fat in the body. In addition to making the belly of the fish large, it also occupies the position of other organs in the body, resulting in the goldfish from small to large, and gradually drop its head (so some goldfish will get better if they stop eating, and will drop its head if they feed); 3. The above two points have shown that even a healthy goldfish is an individual who is adapting to the balance, and is not very unstable. Therefore, when the goldfish encounters sudden changes in the external environment (sudden drop in water temperature, etc.) and feed (from fresh to puffed), it also has the risk of falling head; 4. The above are all about the possibility of the danger of falling head under the condition of goldfish's body and physical stimulation, but there is another way to say that from the pathological point of view, the body balance of goldfish depends on an organ called "otolith" near the back of the gill cap, which is like the human cerebellum, through which the air inflow and outflow of each swim bladder can be controlled, as well as the sliding of each fin. If the otolith is infected by bacteria or virus, It's easy to fall head. However, if I hear of this situation, I can use boiled mung bean flowers to feed fish, which can play the role of detoxification, so that goldfish can be alleviated
