The appearance of mucus on koi needs to be taken seriously

        The vast majority of people have the experience of touching fish and catching loach and so on, I think we must be impressed by the slimy liquid on the fish, often dipped in a hand of mucus, the fish still slipped away from the hands. Where does this mucus come from, and what is its role?

        Fish are older vertebrates. Most of the fish we usually see are covered with hard scales. The skin of fish consists of the epidermis and the dermis, and the scales are located between the epidermis and the dermis.Fish scale is a unique skin derivative of fish and one of the main features of fish. It is composed of calcium, covered in the fish body surface all over the body or a certain part, can protect the fish body from mechanical damage and external stimulation of unfavorable factors, so there is a"exoskeleton (the carapace of insects, crabs etc)"The name.

        The epidermis of fish is very thin and consists of several layers of epithelial cells and germinal layers thatThe epidermis is rich in unicellular mucus glands, which can continuously secrete viscous liquid, making the body surface form a mucus layer, lubricating and protecting the fish body, such as reducing the friction resistance between the skin and the water; improving the ability to move; removing the bacteria and dirt attached to the fish body and so on. At the same time, make the body surface slippery easy to escape from the enemy.Therefore, the epidermis is of great importance to the life and survival of fish.

        In the case of koi, in the absence of disease, there is a layer of mucus on the surface of the body itself, which is relatively homogeneous, transparent and slippery. In the case of disease, the mucus on the surface of the body will vary, partly opaque or even white fluff or"nasal mucus"The mucus is a sign of disease on the koi's body surface.

        The mucus secreted by koi is a state of self-protection, which is mainly manifested when koi are emotionally stressed, or when they are externally stimulated by a new environment during a water change or over-watering, and it is normal for koi to secrete mucus at this time.

        It is important to note that when koi secrete mucus it is also a time when the resistance of the fish is extremely low, making them very susceptible to bacterial infections and fish diseases.The solution is that you need to be more observant.Less tossing and turning, don't mess around with medication, and maintain good ecological water.on average3-5change day by day1/3The water will be fine after the koi have recovered themselves. So, this is the time to test your water keeping skills.

        herebyWe wish all of you good health for your Koi. We would like to remind you that in our daily management of koi, we should pay more attention to their physical condition, so that we can be the first to find out the abnormal state of koi and treat them in time.
