As we all know, aquaculture cannot avoid parasites. However, with the increasing attention of food safety, professional pesticides, because of their high toxicity, residues, pollution and other reasons, have been listed as banned drugs and will soon be included in the banned drugs, more and more are. Even if it is a pesticide that can be used, the physical damage to fish and shrimp is very large, and it is easy to cause poisoning and even serious losses.
Chinese herbal medicine is the crystallization of the rich experience that the Chinese nation has gradually recognized and accumulated in the long process of survival. The application of Chinese herbal medicine in aquatic products is also more and more extensive, compared with Western medicine, Chinese herbal medicine has many advantages: non-toxic (low toxicity), no drug resistance, both symptoms and root causes and so on. Similarly, Chinese herbal medicine can also have a good performance in parasitic diseases, so let's learn this knowledge together.

Chinese herbal medicine is the crystallization of Chinese wisdom, and the reason why today's society rejects traditional Chinese medicine is only because we don't know enough. There are several important points to keep in mind when using Chinese herbal medicines to control parasites:
1, Chinese herbal medicine, relatively professional insecticide safety is much, low toxicity, drug resistance is basically no. But it is still necessary to note that excessive dosage will still be poisoned! Too much use can still lead to drug resistance (not resistance, but resistance)! Therefore, we must not blindly increase the dosage of Chinese herbal medicine because it is relatively safe (too much rice will be supported), nor can we use it purposelessly every day.
2, the use of Chinese herbal medicine prevention, we can according to the characteristics of seasonal parasitic diseases, targeted prevention, we can do more with less. For example, in the season when wheel worms are frequent, soak the "neem" branches and leaves that can be seen everywhere in advance, and replace them when they are soaked until there is no color; the varieties of fish and mackerel that are easy to get can prepare more bayberry trees, camphor trees, and masson pine branches and leaves (these are not difficult to find). These prevention methods are not only safe and inexpensive, but they can really work.
3. Most of the Chinese herbal medicines have no killing effect on parasites, but play a role in preventing and repelling insects.
Small melon worm disease is the number one disease of many varieties, if you use Western medicine preparations such as copper sulfate to kill, it will kill more and more. The use of ginger and pepper to treat small melon insects, the effect is very good in small water bodies such as cement ponds, because after ginger and pepper mixture under the pool, small melon insects will fall off the fish body, at this time, then change the water, basically healed. However, shedding is not the same as killing, if in the large water body, there is no condition to change the water to replace the small melon worms, it will recur in a few days.
So, in the large water body that is not convenient for changing water, is Chinese herbal treatment useless? No, we can first use ginger pepper mixture to let the small melon worm fall off, and then appropriately sprinkle the insecticide that kills the small melon insect, so as to avoid the problem that the fish body instinctively secretes mucus, causing the small melon insect to be difficult to kill.
Most Chinese herbal medicines can play a role in removing mucus during use (similar to the medicinal effect of ferrous sulfate). Therefore, we can also use Chinese herbal medicines to remove a part of the mucus while using professional insecticides, so as to achieve a multiplier effect with half the effort.
Do you understand this trick? Medicine, are useful, the key depends on how you use (collocation) only!
4, in practical use, various types of insecticides have their own strengths and weaknesses, the same is true of Chinese herbal medicine, how to promote the strengths and avoid weaknesses, with combination, this is the way we have to think. The application of Chinese herbal medicine in aquatic products, because of its remarkable characteristics, has become a trend and trend, and it is also an inevitable choice for food safety. The aforementioned neem control wheel worms, ginger and peppers to treat small melon worms, whether it is prevention or treatment, have a good effect.
Chinese herbal medicine is the great crystallization of the Chinese nation, the content is broad and profound, can prevent and control parasites of Chinese herbal medicine, but also far more than the text listed in these, let us learn together, for the aquatic industry and the people's food safety and work together.
Chinese herbal medicine can not only control parasites in aquatic products, but also control other diseases. So how should Chinese herbal medicine be prevented from other diseases? Stay tuned to the "Fishing Connoisseurs - Luo Houbing" column.
