Recently, when some anglers were fishing in Xiangmi Lake, they caught two strange-looking "strange fish" in succession. This "strange fish" looks very much like a tilapia at first glance, but the difference is very obvious, because its body is covered with star-like spots, and the appearance of the fish body is dominated by rare green and dark green. In short, its appearance is quite strange, and it is rarely caught by anglers in wild waters.
Since this fishing friend is the first time to catch this fish and does not know this fish, he is a little surprised: how can there be such a fish in the rivers and lakes of Shenzhen? So there are many questions: won't it be a new alien species?
Because they had not seen it, with all kinds of questions, the angler took home a few "strange fish" he caught, took out his mobile phone to take a few photos, and sent it to the Internet for help. The fisherman said that "the more you look at the flowers, the more wrong it is, you don't dare to eat it, it looks like it is very fat, but you are afraid of eating accidents." Because "friends with certain life experience know that the more beautiful the appearance of the creature, the more dangerous and even toxic." Finally, the angler gave these "strange fish" to the neighbor and fed them to the cats.
Since the photo was posted on the Internet, almost no anglers in the 80 million fishing army knew about the fish, but it caused a sensation and a lot of discussion. The most credible claim is that the tilapia is a hybrid of other fish, and it is the latest hybrid tilapia in China.
To this end, the reporter of shenzhen evening news sent the photo to the fish experts, and specially consulted the aquatic experts of the South China Sea Institute of the Chinese Academy of Sciences, the South China Sea Fisheries Research Institute of the Chinese Academy of Fishery Sciences, and Li Zuoshan, president of the Shenzhen Fishing Association. Through his identification, it is believed that this "strange fish" is not a "hybrid tilapia", but a cichlid fish native to Nicaragua in Central America, commonly known as the flower tiger. Li Zuoshan and a number of senior anglers in Shenzhen jointly identified that the "strange fish" is a variant of freshwater tilapia and freshwater grouper hybrid tilapia. According to some senior anglers in Shenzhen, some people caught this fish in Xiangmi Lake 20 years ago, and it is determined that it is an exotic species.
When you hear that it is an alien species, the first reaction of the anglers is, is it another alien species invading our waters? Started flooding? Will it cause flooding? Graduate anglers have deeply experienced the experience of invasive fish such as tilapia, and the tilapia that fills the waters squeezes the living space of native fish.
The flower tiger is just an alias for it, the real name is leopard stone fish, belonging to the cichlid family, scientific name: heros managuense, native to the rivers and lakes of Costa Rica, Honduras, Managua and Nicaragua in North and Central America.
Adult fish are about 30 to 50 cm f long and can be eaten, and are very popular with locals in Central and North America, and are a popular edible fish in their places of origin. In the family Cichlidae, it is a huge species, because the stripes growing on the body are very similar to the leopard prints on the leopard, so it is also called the leopard stone fish.
The flower tiger is a flesh-eating fish with a hot temperament, and the fish meat of various fish is its best food, feeding on other fish, crustaceans, and invertebrates. It can feed on much larger fish and is very harmful to other fish.
The habitat of the flower tiger is streams or lakes, and prefers to live in highly improved water quality with sandy mud bottom, mostly in the middle and lower layers of water, and occasionally in the upper layers of water. Known as a strong killer fish. At the same time, it is also a large ornamental farmed fish.
The flower tiger was originally native to Central America and has nothing to do with China, so why is it in China's waters? Because the tiger fish is delicious and more delicious than tilapia, it was introduced to China for breeding, but it was originally introduced for the purpose of ornamental fish.
According to relevant literature, the flower tiger fish was first introduced to Taiwan Province, and was introduced to Taiwan Province of China in 1988, which is a common freshwater aquaculture species in the southern region of Taiwan. Because of its certain ornamental and edible value, in 1996, some breeding units in Guangdong and Jiangxi introduced flower tigers from Taiwan.
The introduction of tiger fish into domestic waters as an exotic species is not a small harm to other species in our country. Because of its temperament, very fierce, is a killer fish, so the local crucian carp, carp, mud carp, loach and other fish, are not its opponents, become its plate food.
1. The choice of fishing spots
The habits of the flower tiger fish are slightly similar to those of tilapia, and its living environment is highly overlapped with that of tilapia, preferring muddy and sandy bottom waters. However, tilapia is an omnivorous fish with a plant-based diet, and flower tigers are pure carnivorous fish.
Fishing points need to be selected in the waters with sedimenty bottoms, it also has a feature to note that it likes to inhabit the stone cracks, so the fishing points need to have a certain amount of rock piles and other waters, these places have more stone cracks, suitable for its survival.
2. Bait
It is a carnivorous fish, and it is necessary to use meat bait when fishing, and you can use fish meat, earthworms and other meats as bait, but the best bait is the big black earthworm, which is better than any bait.
3. Fishing set
For fishing groups such as fishing rods, main lines, floats, and hooks, there are no special requirements, and they are common with fishing groups for tilapia. It should be noted that its individual is larger and heavier than the tilapia, and the fishing set needs to be relatively better.
To be sure, the flower tiger is an exotic species, and its origin is Central and North America. Originally introduced from Taiwan Province, it was a fierce fish that caused catastrophic damage to native fish, especially crucian carp and crucian carp. As for why it appears in natural waters, it is mainly caused by escape and artificial stocking during breeding. At present, it has not reached the point of flooding, and it exists locally in natural waters.
Here's an appeal, people who hope to release them, don't think that the flower tiger is good to buy and release, and the indiscriminate release of alien species is actually a violation of the law. At the same time, I hope that when anglers catch flower tigers, they must not release them again, and they can eat it with confidence, because its taste is better than that of tilapia. Take home mainly steamed goby, or fried until fragrant.
