Are parasites also present in freshwater fish, and can they be eliminated by the normal production p

People must pay attention to hygiene in the process of eating food, and will find that whether it is freshwater fish or seawater, there may be parasites in the fish.

exists. In general, the normal home cooking process can eliminate the parasites in the fish by cooking at high temperatures, but the method must be correct.

In the summer, the temperature is getting higher and higher, many people are looking for delicious food, at this time it is very good to eat cold food to relieve the heat, you may eat cold noodles and ice melon ice powder, if you choose the wrong food, the consequences are also particularly serious. According to the relevant information, it can be learned that there is a man who has been using sashimi for a long time.

After that, a fever develops.

The condition was sent to the hospital for examination, and it was found that there were parasites in the liver, and the name of this symptom is liver fluke.

When people choose to use large water fish for sashimi, they should also pay attention to disinfection, because many sashimi are made with deep-sea fish.

If you eat sashimi made from freshwater fish, the risk of parasitic infection will be higher.

It is necessary to understand what is the difference between deep-sea fish and freshwater fish to make sashimi, there is a big difference in taste, because the living environment is different, freshwater fish mainly include carp, grass carp, and absolutely fish, because these fish live in freshwater areas, and this water quality pH value.

It is very stable and does not have other bad conditions, so parasites and bacteria can easily lodge in fresh water.

Freshwater fish live with parasites all year round, and there will be some parasites in the body and infection, if you don't cook this kind of food in the right way, there will be a second infection of parasites, and the possibility is particularly high. Deep-sea fish generally include sardines.

Monkfish, these fish live in the ocean, the environment in the ocean is very harsh, the general parasites can not survive, so there are fewer parasites in the sea fish, use this fish to make sashimi, the probability of parasites appearing is low, so freshwater fish are generally not able to be used to make sashimi, there will be a risk of infection, you must use the right way to cook at high temperature, this cooking method is correct.

The parasite is a pathogenic and low-pathogenic eukaryotic organism, and most of the parasites are relatively common in animals. It can be said that parasites are ubiquitous, and most of the infected parasites in the human body are infected through animals or undercooked food, etc., so are parasites also present in freshwater fish? Can the normal production process at home eliminate the parasite?

Freshwater fish mainly live in freshwater areas, due to the current environmental pollution is particularly serious, and most of the freshwater fish are intensively farmed, long-term living in freshwater with serious environmental pollution, it is easy to cause freshwater fish to have parasites in the body, if you eat freshwater fish food without cooking treatment, the possibility of human infection with parasites will be relatively high.

1. Parasites can be said to be everywhere, even the usual vegetables will have parasites, the normal production of the family can eliminate parasites, but we must master the method, such as boiling vegetables must be boiled in 100 degrees of water for more than 30 minutes, in order to completely eliminate the eggs and parasites on the vegetables.

2. Most of the seafood has parasites, although the seafood is frozen during processing, the freezing temperature is not low or the time is not long, and the pathogenic bacteria of the microorganisms cannot be completely frozen to death. Or it may carry some germs, viruses or parasites in the water or flow of the breeding body, and in the process of home processing, so the best way to completely eliminate the parasite is to cook it thoroughly.

3. In fact, the risk of parasites in freshwater fish is relatively large, and the current means of killing parasites are not only high-temperature cooking, but also freshwater fish can be refrigerated at a temperature of minus 20 for more than 24 hours before they can directly freeze the parasites to death.

It can be seen that freshwater fish will also have parasites, so everyone must cook freshwater fish when eating, and then eat it after cooking thoroughly, and must not use freshwater fish to make sashimi, the fish itself has been infected by parasites, and the risk of parasite infection will be further increased when eating raw fish fillets.

There are also parasites in freshwater fish, and normal production tools can eliminate these parasites, and in the production process of freshwater fish, we must observe whether there are such parasites in our fish to avoid affecting the body.

The normal production process at home can eliminate parasites in freshwater fish.

If it is made in the right way, it can be eliminated, as long as it can be heated.

But those who love animals, even if they do not raise cats and dogs, they will raise some kinds of goldfish, which not only increases their vitality, but also delights their mood, but fish will also get sick, such as some fish parasites, parasites are more troublesome than general diseases, so how to reduce the occurrence of fish parasitic diseases, breeders should pay attention to it!

1. First of all, this step in the purchase of fish is quite important, do not buy sick or abnormal fish, when buying fish, observe them more, to see if their body color is normal swim lively or not? Is it diligent or not? How about having white stools?

2. Secondly, in terms of feeding, we all know that we all know that eating more meat for fish has a great effect on the brightening of the fish body, but some live bait is easy to carry parasites, especially red worms, bloodworms, and water fleas. There is also no need to feed live bait at meals, you can get it at intervals, and you can also feed some feed insects to dry these, so that the fish will not pick their mouths.

3. Do a good job of disinfection of water quality; This is related to the usual care, so there is no fish tank that does not change the water, regularly disinfect and change the water, don't say that you are afraid of trouble and do not want to clean, just change some water, this is not advisable, the fish tank wall that is not cleaned for a long time is easy to breed moss, and the accumulation of feces will block the drain and easily mix the water. Do regular preventive deworming, which is done on the last few days of the month, first in vitro and then in vivo (the medicine used in the body is a deworming burger).

4. Reduce the urgency of the fish, don't think that the fish is so beautiful and eye-catching, so that not only does it not have any sense of beauty, so that there is a very depressed and urgent feeling, but also will cause the collapse of the filtration system, reduce the resistance of the fish, easy to get sick and have no energy, lie on the tank, gather together, do not eat, these are more common states.

The above methods are quite effective against ** fish parasites, we cannot guarantee that the fish will not get sick, so we must always pay attention to the fish's every move, once we find that there is an abnormality, we must prescribe the right medicine.

It's not that marine fish have fewer parasites than freshwater fish.

It's not that marine fish have fewer parasites than freshwater fish. According to the China Fishery Association, wild fish mainly prey on small fish and crustaceans, which provides a route for parasites to spread among fish. As for salmon, the China Fishery Association said that the open living environment and uncontrollable predators make wild salmon much more likely to be infected with diseases or parasites than farmed species.

Compared with other freshwater warm-water fish, rainbow trout culture environment is very demanding, generally using natural reservoirs or underground springs, and the probability of parasite infection is very low.

Liu Chun'e, an associate professor at the Yantai Research Institute of China Agricultural University, said that freshwater fish carry much higher parasites than saltwater fish in terms of the parasites to which humans are susceptible. When testing, it is mainly to detect several common parasites that humans are susceptible to infection.

Wu Qing said that all living things have parasites, but most of them do not cause harm to the human body and do not infect humans. There are few types of parasites that are transmitted from fish to humans and cause human disease, mainly some nematodes, fasciolates, tapeworms, etc., which can be transmitted to humans and may cause human diseases, these parasites may be carried in both marine fish and freshwater fish, but mainly wild fish.

Whether salmon has parasites or not depends not on whether it grows in seawater or freshwater, but whether its growth process is safe and controllable. With industrial farming with management standards, strict monitoring, clean water and excellent feed, the quality of salmon is easier to ensure and safer to eat. The China Fishery Association emphasized.

Fish is a parasite that is difficult to find. If not carefully observed and **, the fry will eventually lead to ulceration and death. You don't seem to be very familiar with this parasite, so don't worry, in this ** we will talk about preventing fish poisoning, killing fish poisoning, etc.

But be careful! Fish lice are not the same as fish lice! Fish lice live in the mouth of the fish, not on the tongue, and are also known as "head lice".

But today we are talking about fish, which are parasites on the surface of the body. What fish market? Fish grow these things?

Fish are small and it is difficult to find ectoparasites. In general, the body of an adult is only five to six millimeters long and reproduces quickly.

<> its body is translucent, it has two suction cups that can be firmly attached to the surface of the aquarium fish. There are four pairs of feet on the chest, which can be used for swimming. Swimming parasites are really rare, and when they can't find a host, they keep swimming until they find one.

There are needle-like mouthparts like mosquitoes, which they use to feed the blood of aquarium fish, which is obviously not good for the fish. Fish are comparatively difficult to spot. After all, it is translucent, only about five to six millimeters in size.

If you're not careful, it's hard to spot.

It's fine in glass jars, but it's almost impossible to find in dark containers. In general, fish infected with fish will have some more obvious symptoms. When the number of fish reaches a certain level, the aquarium fish will become very impatient, have a hard time settling down, like to collide, and it will also be accompanied by the phenomenon of rubbing against the fish tank.

If your aquarium fish is rubbing against the tank frequently, don't worry, you must first take a good look at the surface to see what the problem is. As long as the naked eye is a fish in a glass fish tank, if the fish is infected, you should be careful or visible, and pay more attention to the gills of the finfish. The main ** of fish may be to feed on live fish worms.

After all, this thing looks like a fish worm and it's easy to get in when you feed it.

The main problem is the ** of fish and worms. Wild fish are most likely to carry fish. Be sure to pay attention.

Frozen fish worms usually do not. So, once it is confirmed that a fish is infected with fish, what should be done**? Ectoparasites are actually quite easy to deal with.

If the quantity is low, remove it manually. But if there are many, every fish, you have to give them medicine as soon as possible. Let's start with the lesser stuff:

Generally, it is less buckled, but it is difficult to buckle, because the fish stone has two suction cups, and it is recommended to use a 1% concentration of trichlorfon solution to apply it where there is a fish stone.

First of all, don't buy sick fish, this fish is likely to have parasites outside the body, and secondly, the newly bought fish should be vaccinated to ensure safety, 3 The number of feeding live bait should not be too much or not too much at a time, and finally the cleaning of water quality disinfection should be in place.

Generally, potassium permanganate powder is used in aquariums, which is poured into the tank for soak and disinfect after being flushed with warm water according to the specified proportion, and then discharged.

In the process of fish farming, if you want to reduce the parasites in the aquarium, you must pay attention to the management of water sources, disinfect them regularly, and change the water sources frequently.

You can buy sashimi through regular channels, and pay attention to check whether the merchant has the "Inspection and Quarantine Certificate for Imported Goods" to ensure the safety of sashimi as much as possible. Reducing the frequency of sashimi consumption also reduces the risk of contracting parasites.

Sashimi "companions" such as mustard and vinegar are less effective at insecticidal purposes. Although both of them do kill parasites in the laboratory, they are tested under conditions of high concentration of wasabi and high concentration of vinegar, and sashimi with parasites soaked for a long time.

However, it is difficult to soak sashimi in high-concentration condiments for a long time before eating it in daily life. Therefore, the purpose of parasite eradication cannot be well achieved in this way.
