? Tilapia is one of the common fish in the market of our country. It can be used as food. It is rich in nutrition and tastes good. Some people worry about the toxicity of tilapia. There's no need to worry. Tilapia are poisonous. The term actually refers to their dorsal fins. There are some sharp thorns on their dorsal fins, which are poisonous, and if humans are pricked by these thorns, they may also be poisoned. However, the toxicity is very mild, generally speaking, there will only be symptoms of swelling and pain, timely disinfection treatment will be fine. Moreover, in the case of high temperature, this slight toxin will be decomposed.
In addition to the thorns, the other parts of tilapia are actually non-toxic, their meat is not toxic, edible and nutritious. However, there are still some problems that need attention. First of all, there is the problem of parasites. Fish living in water may carry parasites, so they need to be cleaned and cooked before they can be eaten. Moreover, if tilapia grows up in a dirty environment, the body may accumulate more lead and mercury, which are harmful to human beings, so we must buy tilapia from regular channels.
? Swim bladder is a common structure in fish, commonly known as fish bubble. Air can be stored and released in the swim bladder, and fish can control their rise and fall in the water in this way. But some fish don't have a swim bladder. Tilapia is a fish that doesn't have a swim bladder. The swim bladder is important for fish, and it is not convenient for tilapia to have no swim bladder, because they can only control the rise and fall in the water through their own swimming, and they are rarely in a static state.
