Hello aquarists, I am a fish farmer, and everyone can easily raise water, happy and happy to raise fish, please pay attention to aquarists!
Recently read a lot of reports on the flood of fish in the wild, it is still very interesting to think about it carefully, in general, it may be that various fish in our country have performed better abroad.
First, tilapia, Egyptian pond carp, scavengers, crocodile eels, fortune cats, etc., in fact, are not tolerant of low temperatures, and many can also be served on the table
Many of the above fish, many of which are introduced to the country due to the needs of breeding, such as tilapia, sunfish, Egyptian pond carp and the like, these fish also have some as ornamental fish, they have their own characteristics, such as reproductive ability is very strong, adapt to a variety of water environments, for food is basically not picky.
The Egyptian pond eel, crocodile eel, fortune cat, etc., are large freshwater fish, and there are not many natural enemies in the native waters themselves, not to mention the crocodile eel, with thick skin and thick flesh, knives and guns.
Scavengers have similar characteristics and are more survivable, feeding on various fish eggs from the origin, which is a headache for many farmers.
However, this type of alien species also has two fatal shortcomings.
One is that they are all not tolerant to low temperatures
Most of these fish, below five degrees above zero, are absolutely unlikely to survive.
This point can easily kill them, it is the fatal wound of these fish, so it is extremely difficult to find their figure in the northern region of our country, even if it is found in the summer, the winter will be finished, their habit of being afraid of cold, it is not a short-term change.
The second point is that a lot of fish can be brought to the table by us
Our people have a lot of food, which is difficult for any other country to do.
Perhaps because of the aesthetic concept or disgust for some fish, such as scavengers and Egyptian pond carp, many Chinese people feel that they are disgusting.
Not necessarily.
It should be said that the fish itself is relatively clean, just the problem of living in the waters and ingesting food, catfish this thing, I believe many people have eaten before, but in recent years it is popular to say what is the big dung water to grow up, where so many septic tanks come from?
They are also impossible, facing the vast natural waters of our country, specifically drilling into that septic tank, which is only a minority after all, so now, there are many Chinese people who are trying to eat scavengers or catfish, it is said that the cooking method is appropriate, the taste is not bad.
Therefore, these foreign invasive fish, in our country still can not make any waves, at most in the local area may appear in large quantities.
Second, China's fish, that is quite domineering, the water temperature is not afraid, foreigners do not eat, catch may not be able to catch
Needless to say, let's just say that our koi and wheat ears can be, haha.
China's native carp is large, disease resistance is strong, and the reproductive ability is stronger, not afraid of high and low temperatures, between about zero degrees to 35 degrees, can survive at will, in a variety of temperatures to tour back and forth ah, without any survival pressure, have the ability to come, who is afraid of whom.
And the wheat ear fish? It is said that he has traveled all over Europe and the United States, and has traveled to all corners of the world.
Don't look down on this little thing, what origin of all kinds of fish eggs, all clean for you, not only strong fertility, but also the broodstock will also take care of the small fish, adapt to the water temperature and China's native carp, absolutely can not distinguish between a high.
And the size of the wheat ear fish, comparable to peacock fish, mosquito-eating fish, then come, so small individuals, even catch has become a problem.
No matter what kind of fishing net is laid, it has to be salvaged together with the size of the fish of the origin, so the people of our country said that they are very helpless.
Native carp, our way of eating can go more, what sweet and sour carp, steamed, braised, we can also make fish dumplings locally, the taste is also very good.
Wheat ears we will not let go, fried a plate, crispy and delicious ah...
Therefore, for the invading fish of various countries, who is stronger or weaker? This is still an unknown.
I am a veteran of fish farming, more ornamental fish problems please pay attention, thank you!
