The kitchen snails of Tinh Que establishment in Cao Lanh are becoming a commercial product that attracts attention. Previously, I only heard of this dish orally. How do you say that? Not at the end of the market. The establishment’s instruction manual for snails is on the package – a bamboo basket with wide eyes, the size of a human head. I don’t remember the verbatim, but the gist is that before steaming, put the snails in a large container and put three eggs in it with a bag of milk. Let it take about two hours for the snails to drink up before it is processed. People in the West know how to take advantage of the behavior of the common convex snail called pila: in the dry season, when you sleep, in the rainy season, you wake up to eat, to invent the kitchen snail dish. There are several types of edible apple snails: the field snail (pila polita), which lives in garden ditches, canals, along the edges of fields, in the fields, and snails (pila gracilis) (1), which live in places where there sedges – perhaps hence the name, and rock snails (pila?), which live in the mountains. In terms of quality, snails are the best, because the meat is chewy and lumpy. More than two decades ago, snails became increasingly scarce as a result of scientists calling for the import of golden apple snails for export. The golden apple snail is an invasive species that has become a scourge for rice-growing countries. As an invasive species, rapidly growing herds, spreading on a large scale, so according to the ‘territorial law’, ‘yes, I don’t have you’, the snail has almost disappeared. The basket of snails in the kitchen of the Tinh Que establishment. Photo: NGUYEN NGUYEN Snail snails are different from the common-eyed apple snail, which is the low, not pointed and tall snail tower like the bronze apple snail. In recent years, people in Dong Thap have chosen to raise snails a lot because of the higher commercial price, due to a time of scarcity. Buyers of snails in the attic also choose snails. The pila snail is an amphibian, lives on land during drought, sleeps all the time and breathes through lungs. In the rainy season, it lives under water, breathes with gills and goes foraging. According to that habit, people put snails in baskets in the attic of the kitchen for snails to sleep for a long time. When you want to eat snails, give them a ‘gracious’ meal of good food. Normal snail meat is delicious, feeding them milk and eggs will be more delicious. There is something to pay attention to the fire, so that the snail does not get tough. Eat bulot, fence the sea People who know how to eat bulot snails must first be cod from Newfounland from the late 19th century, then Normandy, French, etc., then Saigon and Can Tho. Not sure if I am the last person to know about this snail when eating them in Can Tho at the end of April 2021? Eating a snail, don’t say it’s good or bad, the more thought-provoking thing is how the French conserve resources through fishing restrictions. In 1970, the opening Granville auction attracted interest in the bulot sea snail. Before that, the luxury on the dinner table of Westerners only had oysters and red crayfish. As for snails, there are only snails living on land that many Vietnamese shake their heads. In 1980, a group of operators was formed, and in 1985, mining required a license. The smallest size snail to exploit is 4.5cm long. In 2000, due to a decrease in stocks, many measures were put in place: a fishing break in January, the time when snails spawn. The quota is 300kg per person and 900kg per ship, limiting the number of permits, increasing the separation distance from 1.9 to 2.2cm. The number of catches was reduced by 6,000 tons, the number of miners was reduced from 82 to 68. The catch of bulot snails is only using trap cages. Fishermen use cages with bait dropped on the sea floor to lure snails. Fishing as if it does not frighten the snail, stress reduces the quality of the meat. Stir-fried bulot snails with garlic butter. Photo: NGUYEN NGUYEN In the past, bulot snails were only caught by the French as bait for the large cod fishery in Newfoundland as far as Canada. Specifically, on May 18, 1886, the Newfoundland Parliament enacted a law prohibiting people on the island from trading with foreigners and especially not selling and exporting bait to French fishermen. This bait includes squid, herring or roe. Difficult to get wise, some French fishermen came up with the idea of ​​​​using bulot snails as bait for cod fishing. A long time thanks to the new type of bait, the catch is estimated to be five times more. Saint-Malo authorities, press fear a resource depletion. All of a sudden, the cod didn’t want to eat the bulot bait anymore. It wasn’t until the early 1980s that the snail, scientifically known as buccinum undatum, appeared on the dining table and in the kitchen. Within 20 years, the French quickly realized the problem: the output was getting bigger and bigger, the resources were getting exhausted. Obviously the snail meat is delicious. The day I ate snail bulot in Can Tho, the shop sold by the slice. The dish is called snail bulot sauteed with garlic butter. For the French, known for their fine dining, they say an ontological question has long haunted them about the relationship between snails and mayonnaise: can the former survive without it. the second one? It’s like the correlation between snails – the national drug of the West – and garlic butter. It’s horrible to be missing either. But Vietnamese tongue overturns two pairs of categories. They let snail bulot survive with garlic butter. That day I ate delicious and fragrant. But the smell of the sea is only very light, maybe it is a more subjective feeling, because in Vietnam, I used to eat all kinds of sea snails. Bulot snails from France are imported to Vietnam in the form of frozen snails with their shells intact. Many places sell online for prices from 350,000 VND or more, depending on the size. But certainly there is no milk snail like milk squid, milk anchovies, milk crabs in Vietnam. Strict European fishing regulations. The last class snail is 4.5cm, each class is 2.2cm apart. The people of Granville are also worth learning that, although snails are found in many places in France, they have registered for geographical indications early. The Protection of Geographical Indication (PGI) for the Granville Bay bull snail was granted on February 7, 2019, after 7 years of filing. PGI is the quality talisman of this bay snail. —– (1) – Ngo Thi Thu Thao, Le Van Binh, Comparison of some morphological and reproductive biology characteristics of the field snail and the autumn snail in Dong Thap province, Can Tho University.

Dolphins evolved from a terrestrial animal Dolphins evolved from a terrestrial animal Dolphins are mammals, closely related to whales, often living in the shallow seas of the continental shelf. Dolphins have the ability to understand simple human behavioral language. With their inherent magical ability, dolphins can understand and organize common objects into groups together. They understand both sounds and images, and even respond to images just like humans. Explaining this, scientists have confirmed that dolphins are the most intelligent animals in the world (while humans are only third in intelligence). Millions of years ago, the ancestor of the dolphin did not swim in the water as we know it today, but was a carnivore that lived entirely on land. However, about 50 million years ago, a mysterious event happened that forced them to adapt to the underwater environment, and gradually evolved into a mammal like today. Although they are considered extremely friendly animals, dolphins also have creepy habits, typically juggling their young out of the sea. This sounds like a very funny joke, but in reality, it is one of the ways adult males are killing their young so their mothers can return to mating. Dolphins can’t sleep for weeks at a time A recently published study has revealed the surprising ability of dolphins: They can stay awake for days or weeks at a time without sleep. So how can they survive without sleep? Dolphins possess a very special sleep mechanism, they can let half of their brain rest at a certain time while the other half is still awake – a process called “Unihemispheric sleep”. This special sleeping mechanism not only keeps dolphins from drowning, but also allows them to stay alert to any danger and even encourages brain development. Most dolphins don’t chew their food Dolphins do not chew food, or rather they cannot chew. Dolphin’s teeth are developed for the purpose of gripping prey. Sometimes they will shake or rub the food on the ocean floor to tear it into smaller pieces that are easier to swallow. One theory is that dolphins’ prey are mainly small fish, and they need to quickly grab the prey in their mouth before their meal can swim away. Skip the chewing process to make sure the prey can’t escape. Dolphins call each other by their own names, forming friendships through shared interests Researchers from the Universities of Bristol, Zurich and Western Australia have found that dolphins living in the Shark Bay area form friendships based on shared interests – in this case, the habit of using foam. sea ​​to hunt. This tool-using trait is found mainly in female dolphins, but by studying the behavior of a few expressed male dolphins, researchers have found a new discovery: The relationship of dolphins is formed through general tooling techniques. Dolphins have their own names and they will respond when called. Dolphins in each population possess their own “characteristic whistle”, just like a name, and other dolphins can use that distinctive whistle to get the attention of their mates. In fact, dolphins are also an extremely social species. The discovery opens up entirely new questions about how dolphins communicate and their “vocabulary,” and may reveal clues about the evolution of our own language skills. Dolphins use prey’s toxins as ‘addicts’ We know that puffer fish have strong toxins. Apparently dolphins know this too, but they use it for ‘high’ purposes. Usually, the puffer fish toxin is deadly. However, in small doses, it can act as a narcotic. The BBC once filmed a video in which dolphins gently play with a puffer fish for 20 to 30 minutes, then hang around and behave “weird”. Dolphins possess great “teamwork” ability A team of researchers from the University of Bristol recently discovered that male dolphins can work and work together as a team – an attribute previously thought to be unique to humans. Observing the behavior of male dolphins as they coordinated courtship with female pigs, the researchers saw cooperation rather than competitive behavior, which is particularly unusual in mate-finding in the animal kingdom.

Domestic geese are fatter than natural geese because when domesticated, people have chosen large geese, domestic geese can weigh up to 10kg while wild swan geese are only 3.5kg and or gray geese are 4.1kg. Although stout, domestic geese can basically fly. The earliest records of domesticated geese suggest they were raised for fattening and sacrifice, but in Roman times geese were also bred for eggs and bred for specific traits such as calm personalities. or for beautiful, luxurious fur. It was not until 390 BC that geese were raised to become a guardian animal in Roman life. It is said that once at the temple of the goddess Juno, there was a flock of geese, they were considered sacred animals and no one dared to eat them. In 390 BC, Rome was besieged by the Gauls, and late one night, Gaul soldiers sneaked up the Capitoline hill where the temple of the goddess Juno was to surprise Rome. The dogs raised by the inhabitants of Rome were not alarmed because they were easily bribed with fresh meat. With the exception of the geese, they immediately noticed the unusual disturbance and began to call loudly. Thanks to the cry of the geese, the Roman soldiers were awakened and successfully defended their city. Since this event, the geese are considered heroes, sacred animals, and an annual festival is held – dressed in purple and yellow geese costumes and teasing them. Dogs because of “greed for food” forgot their guard duty. Goose has aggressive behavior Aggressive geese – this behavior is related to their size – a large and clumsy bird. Geese are difficult to hide when threatened, so they will display aggressive and aggressive attitudes to avoid danger. Goose tolerates extreme weather well, even when it snows, it still likes to be outside grooming. The ability to protect themselves well plus preferring to be outside rather than indoors, geese are often raised by farmers with flocks of chickens, ducks and geese to protect themselves. Day vision (nearly blind at night) and hearing of geese are extremely sharp, they can sense movements long before humans realize. While most birds do not respond to things they see in favor of humans, geese are the opposite. It emits a loud and aggressive sound – these are ideal sentinel and protective attributes. Geese are also territorial, they know where their home is and protect it. Not many domesticated birds are territorial, and fewer are aggressive in the face of intruders. Goose is more aggressive during mating season or when it is with “wife” and cubs. The male goose will immediately stretch his neck to its full length, turn his head to look at you with one eye and be ready to attack, no matter who the threat is. The goose’s protective behavior for mates and young remains unchanged from that of its wild ancestors. The goose lives with one mate for life and it is very loyal to its owner, not forgetting the people and other animals it lives with. Geese are not affected by food, no matter how good the food is. Therefore, many farmers in the world prefer to keep geese to guard the house and protect other animals than dogs. Vegetarian goose Unlike chickens and ducks, which prefer insects, crickets and protein-rich foods, geese prefer to eat plants, very voracious but all plants. When combining raising geese with suitable plants, they will eat all the weeds around and absolutely do not touch agricultural products. Goose has a good memory, it remembers people, distinguishes who is who by shape, gestures and voice, it also knows which chicken and dog friends are next to him and remembers situations and surroundings. around. So what is unusual, disturbing even small, strangers appear, they will welcome with cries and aggressive attitude. *In 1986, the US military purchased 750 geese from German farmers to protect their military bases. Or in Dumbarton, Scotland, the famous whiskey company Ballantine used geese to guard during 1959 until 2012 when it was replaced with security cameras. These geese are called “Scotch Watch”.
