What used to be considered a delicacy on the table is now everywhere in the rural ditches, breeding wildly, and I believe everyone must think of what it is? This fish is not unfamiliar to everyone, sometimes friends in the south who like to fish, often harassed by this fish, this is tilapia.
Tilapia, also known as African crucian carp, is native to Lake Tanganyika in Africa, resembling crucian carp, with spiny fins and mandarin fish. Fushou fish is a widely saline fish that can survive in both seawater and freshwater. It has strong adaptability to low-oxygen environments, generally inhabits the bottom layer of water, and usually changes the habitat water layer with changes in water temperature or fish body size. It has excellent adaptability and strong fertility. It can also reproduce in small waters, even in rice fields, and has strong adaptability to water with less dissolved oxygen.
Because the meat of tilapia is delicious and tender, whether it is braised or cooked, it tastes good, and it contains a variety of unsaturated fatty acids and rich protein, in Japan, this fish is called "a protein source that does not require protein". Therefore, China introduced this fish from Vietnam in the middle of the last century and began artificial breeding, initially in Maoming, Guangdong Province, as a pilot, Maoming area belongs to the tropical monsoon warm and humid climate, sufficient sunshine, abundant rainfall, the average annual temperature of the city is about 23 °C. It is very suitable for the growth of tilapia, so Maoming is known as the "Capital of Tilapia in China".
When this exotic freshwater fish appeared in the market, favored by many people, because of its fewer thorns, tight and delicious meat, the price also climbed all the way, when the tilapia was the most expensive time to tens of yuan a catty, and then began large-scale aquaculture, along with the increase in the number of breeding, some tilapia ran out to survive in the wild environment, the most people did not realize that this fish to the wild environment can cause any problems, when the beginning of the realization is already too late.
Tilapia is greedy by nature, as an alien species, there are almost no natural enemies in China's wild environment, this fish is extremely adaptable, and in order to survive, it will also prey on the seedlings and eggs of other fish, when it spawns, it will be protected on the side, which will lead to a sharp decline in the number of local crucian carp, carp, native fish, such as in Guangxi, the upper tributaries of the Right River, the "raging" tilapia swarm is dense, almost suffocating. For fishing enthusiasts, the number of fish in the river is a good thing, but these flooded tilapia have made many fishing enthusiasts "hate" because the native fish here have disappeared.
Tilapia because of its strong adaptability, in some stinky ditches in Guangdong can grow, so that now many people do not love to eat this fish, but do not need to worry about the health of tilapia on the market, most of the tilapia sold on the market, most of them are farmed and produced, eat feed, do not need to worry about growing up in an unhealthy environment.
Because the price of tilapia is very cheap, 5 yuan a catty, much cheaper than the average fish, and the taste is also good, many restaurants in the fish, will also choose this kind of cheap fish. And tilapia also with its delicious taste, and low price, is also one of the sources of foreign exchange earned by China's exports, every year China will export a large number of tilapia to the United States.
Tilapia is the fourth largest VIP on the U.S. table, after shrimp, salmon and cod, not blown out, the U.S. Food and Drug Administration FDA and environmental protection agency EPA issued the "National Healthy Diet Guidelines" a few years ago, suggesting that the American people double their intake of aquatic products, and then tilapia is positioned as one of the best choices for aquatic products, suitable for all ages.
