Hello aquarists, I am a fish breeder, more ornamental fish breeding, breeding practice knowledge, please pay attention to!
A few days ago, the old fish farmer saw a report that even if it is the first freshwater fierce fish in foreign countries: crocodile eels, they are difficult to survive in China's natural waters.
Similar to the crocodile eel, there are actually many exotic fish in China, including sunfish, tilapia, zhao cai cat, freshwater white pomfret, zhao cai cat fish, etc., and even walrus fish, arowana fish, luo han fish, colorful angelfish, zhao cai fish, as well as many varieties of artificially farmed fish, ornamental fish, are in many waters in China.
But, as one aquarist finally described:
They do not flow into our rivers from the United States or other countries, but swim directly to our table, don't tidy up the excess, in a word, just say what nutritional value they have.
<h1>Although the crocodile eel has a thick skin and fish eggs, it has not affected the interest of foodies</h1>
As the leader of freshwater fish in the Amazon River Basin, the crocodile eel is also an absolute strong in many series of medium and large fish and raptors, and their maximum body length can reach three meters or more, full of fangs, thick skin, almost invincible.
If there are creatures such as otters and electric eels that can compete in the wild, their natural enemies may only be humans.
Unfortunately, though, they met our great Chinese.
The alligator eel is an ancient fish, so it is extremely strong, it can be said that if they enter the natural waters to live, they are almost not sick, and they grow rapidly and eat amazing amounts.
Although it has only been introduced into China for one or two decades, various incidents of alligator eels invading natural waters still occur from time to time.
It is only because they are more afraid of cold, although they appear in other parts of China, but in the winter, they will be frozen to death, so they are mainly concentrated in Guangdong and Fujian.
But even so, they didn't thrive as smoothly as other small invasive fish, mainly because:
First, they have a longer lifespan and a late sexual maturity
Crocodile eels can live for 60 or 70 years, so their sexual maturity is relatively late, and the female's sexual maturity age is about 11 years old, so even if you want to reproduce smoothly, there is still a time problem.
Second, there are more single releases, and the release waters are vast
In addition, due to the huge size of the alligator eel, most of them are kept alone, and the release is also a single release, so they do not have the conditions for mass reproduction.
Third, although it is toxic, it does not affect the interest of many of our foodies
There is also a more critical reason is that the crocodile eel encountered many foodies in our country, although they look fierce and have a certain degree of toxicity, but after a certain treatment, finally went to the table, after all, this thing is large, meaty, eating is also more enjoyable, it is rumored that a variety of eating methods emerge in an endless stream...
<h1>Fortune catfish, individually large, gluttonous, grow in natural waters, are not so unbearable</h1>
Fortune catfish, in fact, and crocodile eels have a fight, their habits and growth rate in the wild is not inferior to crocodile eels, but also full of foodies, the individual is quite huge, almost no natural enemies.
Before, our people thought that this thing was very dirty, because it was rumored that it ate almost everything, even in the septic tank.
However, when they live in natural clean waters, their food is still based on various fish and shrimp, which is not as bad as previously thought, and it is almost the same as the catfish eggplant we usually eat.
Therefore, many foodies, in the wild to catch a large individual fortune cat fish, how can they easily let them go?
It is both nutritious and delicious to eat, the meat is more thorny, the treatment is relatively simple, although they are also more in the wild waters of our country, they still cannot become a climate, and finally only the fate of the table.
<h1>Sunfish, tilapia, freshwater white pomfret, grouper, etc., are originally farmed and eaten fish</h1>
Moreover, fish such as tilapia, sunfish, freshwater white pomfret and the like, they are originally edible, and they are all tropical fish, afraid of low temperature environment, in many parts of our country, they have lost the conditions for survival.
Although they may accidentally flow into the wild for various reasons, our people have long studied their nutritional value and eating methods more thoroughly than their habits.
Accustomed to the taste of many local edible fish, occasionally change the mouth, feel better ah, how they did not expect, in foreign countries can be horizontally overbearing, so that foreigners hurt their brains, to our country, a small matter, no need to hang teeth, just belly.
The only thing that makes us more disgusted and rejected is the scavenger.
Scavengers are different from the above-mentioned fish, first of all, they themselves feed on a large number of fish eggs, the destructive power of the native fish starts from the foundation, and the vitality is not generally tenacious.
Secondly, their ugly appearance does not conform to the aesthetics of our people at all, and secondly, it is some propaganda about their dirtier, so that they can be flooded in wild waters, especially in parts of the winter where water temperatures are higher.
However, even so, many ways to eat scavengers have begun to circulate widely, and it is definitely not that no one eats them, and we can easily find various cooking methods about scavengers on the Internet.
It is only because there are too many areas, and their vitality is very strong, and they have not been suppressed for the time being.
Of course, they can only be flooded in a small area of our country, and can not form a large climate, we can also take a variety of ways to bury in place, make fishmeal, fish feed, etc., to quickly suppress their flooding momentum.
However, although these alien species, some have become our delicacies and swim on the table of our countrymen.
However, we better start from the source, whether it is breeding ornamental or artificial breeding, we definitely do not release one, and slowly they will eventually disappear in the wild.
I am a veteran of fish farming, more ornamental fish problems please pay attention, thank you!
