For the invasion of alien species, not only squeeze the local living space, sometimes cause local economic losses, but there are also alien species have certain economic value. There are many exotic species, there are terrestrial organisms, there are terrestrial animals, and there are also aquatic organisms. Exotic fish, for example, are aquatic creatures.
The invasion of alien aquatic organisms, we first think of scavengers, tilapia, etc., thinking that these are the real alien species. In fact, one of the most common fish species in our southern waters is a real alien species, but this fish is considered by anglers to be the origin of our country. It is considered the most successful invasive fish, invaded for more than thirty years, and can be said to dominate the waters of one side. It exists in the southern water system, and it is the wheat carp! A fish that lives interlaced with the earth carp exists as long as there is a water of the earth carp.
The southern water system is mainly based on the Pearl River system (of course, other water systems are also important), especially in guangdong, Guangxi, Hainan and hainan provinces are the most representative of the south, the Pearl River system is the water system on which the earth carp most depends for survival. As I said just now, as long as there is a place where there is a soil carp, there is a wheat carp, so the Pearl River system is full of wheat carp.

Wheat carp, known as The Wheat Ray Galat, is one of the four largest farmed fish in India in the subfamily Cyprinidae of the Cyprinid family. The country of origin is India and Bangladesh. It also has a presence in Laos, Thailand, Vietnam, Pakistan, Myanmar and Nepal.
The Pearl River Fisheries Research Institute introduced wheat carp from India to China in 1982, and after breeding, it has been vigorously promoted in Guangdong and Guangxi provinces, and then promoted to Hainan, Fujian, Yunnan and other places, and is now an important economic fish species in Liangguang and Hainan, Fujian and Yunnan Provinces, and has become an important breeding species in the southern region.
Wheat carp is a benthic fish, like living water, a bit like the persistence of carp, good at jumping, fishing often see nearshore diving fish are basically wheat carp. Have a habit of foraging close to the shore.
Wheat carp is large, strong adaptability, whether in reservoirs, lakes, ponds, rivers can grow normally, low oxygen resistance and disease resistance is stronger, cold resistance is significantly higher than soil carp, when the water temperature drops to 7 ° C, it can still be normal activity, which is the most obvious difference with the soil carp, soil carp in the water temperature of 7 ° C is difficult to survive.
Another is that wheat carp grows faster than soil carp, and the overall size is larger than that of soil carp. The wheat carp that was bred in that year can basically grow into a head of more than 300 grams, and the largest known individual is more than 8000 grams.
Wheat carp is an omnivorous fish with a wide range of feeding habits, mainly feeding on phytoplankton, higher plants, organic detritus, as well as wheat bran, corn flour, peanut bran and so on.

For wheat carp, the anglers of Liangguang have the most say, and they can basically catch wheat carp when fishing, and many people who fish think that it is a native fish species. In fact, it is an invasive fish, and the invasion history is not very long, only nearly forty years. It is in these forty years that wheat carp escaped from breeding to the wild, artificially released and other ways to release in the wild waters, and then rapidly multiplied and expanded in the wild waters, and the distribution range in the south expanded rapidly. As a result, wheat carp is spread throughout almost the entire Pearl River Basin and is currently one of the most common exotic fish species in South China.
Researchers at Shanghai Ocean University conducted a scientific survey of exotic fish species in multiple tributaries of the Pearl River Basin in August 2019. In the course of the survey, a total of 5867 fish samples were caught, of which 927 were exotic fish, accounting for 15.8% of the total catch.
According to statistics, in the entire Pearl River Basin, there are 10 most common invasive alien fish species, namely The Wheat Ray Galatfish (Wheat Carp), Lusta Wild Carp (Thai Carp), Tilapia, Leather Beard Catfish, Short-lipped Giant Fat Carp and so on. Among them, the largest number is wheat carp, which tops the list with 407 tails, followed by Nile tilapia (360) and Zygosperus (118). It can be seen that wheat carp is more terrifying than the invasion of a single species of tilapia.
In this survey report, the North River, The East River, the West River and other important southern rivers have the presence of wheat carp, and its population can be ranked in the top three, which is one of the most "successful" foreign fish in the invasion.
Many people will wonder, why is wheat carp flooding?
First of all, wheat carp is a warm tropical fish, with similar habits of the soil carp, more hardy than the soil carp, and the temperature in the south is high, which is very suitable for its survival. Moreover, wheat carp has the characteristics of low oxygen resistance, fast growth, strong disease resistance, food habits, etc., and has a strong ability to adapt to the environment, which are the main reasons for the rapid expansion of wheat carp.
Second, it is determined by its habits of life. Wheat carp is an omnivorous fish, hardly picky eater, and can eat anything in the wild water system. The stems and leaves of aquatic plants, various microorganisms, detritus, etc. in the waters are its delicacies, which are everywhere in the wild waters of the Pearl River system.

The fishing method of wheat carp is similar to that of mud carp, where there is soil carp, it exists, and the Meizhou fishing method of the short line is the most suitable fishing method, and it is not unfamiliar to southern anglers. Fishing deep at noon is far away, and fishing near the shore is shallow in the morning and evening.
For the choice of bait, it is recommended to use a fishy bait for low temperatures, and a scented bait is recommended for high temperatures. If you fish during the day, there are more miscellaneous fish in the water, it is not recommended to make a nest; if it is morning and evening fishing, it is recommended to make a nest, and it is personally recommended to make a nest with duck feed, peanuts or wine and rice.
It is a benthic fish with habits somewhat similar to that of crucian carp. Although its range is wide, because its guts are small, it prefers to live in sandy waters under the water and prefer to forage for life in places with better water quality. Choosing a fishing spot requires following these characteristics.
Wheat carp is a group of fish that often frolic and forage together in groups, mixing with mud carp. Often in the nest appears in the soil carp, there is the appearance of wheat carp group. In order not to disturb the fish, it is very important to choose a rod and catch the mouth and lift the fish quickly.

It is undeniable that wheat carp is an invasive alien species, but it was introduced in 1982 and has been invading China for 40 years, and many people think that it is an indigenous fish in China. At present, the invasion of wheat carp to other fish and aquatic organisms in our country caused little harm, its living habits and our country's native fish soil carp living habits are very similar, almost consistent, so it can quickly expand the scope, slowly accepted by people, is currently one of the main farmed fish in the south.
Wheat carp is the most successful fish that has invaded our country, its invasion even exceeds that of tilapia, in the southern waters of its survival range, the number of survival is more and more extensive than that of tilapia. When fishing, as long as you catch wheat carp, it is recommended that you do not release it and try to take it home for consumption. Whether it is fried in oil or made into fish meatballs, the taste is not bad, suitable for the taste of southerners.
