What are sardines?

Sardines are small yellowish green fish that belong to the herring family. Their maximum size is approximately 25 centimeters. Smoked sardines are eaten, like other herrings. But usually sardines are caught when they have not yet reached full growth, and canned food is prepared from them. Caught fish is first placed in fresh water tanks.

The sardines are then gutted, decapitated and descaled. After that, the fish is aged in saline and laid out in large cuvettes, which are passed through the dryer. Finally, the sardines are boiled for about five minutes in boiling oil. Then, after cooling, they are laid out in small flat tins and again filled with oil to prevent drying out.

One of the species of sardines that are found in the Pacific coast of North America, gives the largest catch by weight of all commercial fish. About 560 million kilograms of this fish are caught in one season!

Sardines imported from Europe are found mainly in the Mediterranean and off the west coast of France. By the way, the name "sardine" comes from the name of the island of Sardinia, near which for the first time this fish began to be harvested in large quantities. Most of the sardines caught off the Pacific coast are not used for canning at all, but are processed into oil to make soaps and paints, and are also used to make poultry and livestock feed.

The female sardine lays during the season, mainly in April and May, from 100 to 300 thousand eggs. The offspring appears from the eggs in about three days, and after three months it begins to gather in schools. Sardines feed on small plants and microorganisms, and in turn serve as food for larger fish, such as salmon.

Sardines move in huge shoals close to the surface of the water.

Who was the first person to fly into space?

The launch of the world's first artificial Earth satellite marked the beginning of the space age, and on April 12, 1961, the Vostok spacecraft with a man on board took off from the Baikonur cosmodrome.

Yuri Alekseevich Gagarin, who opened the way to space, circled the globe in 108 minutes and landed in a given area. And behind every minute of its flight - search, hard work of designers, engineers, workers of all specialties. Man's old dream came true - to gain wings and fly over the Earth.

The whole planet loved him. It has become a symbol of our time. However, he did not want to stop there, he was preparing for new flights ... A tragic accident during one of the training flights on a jet aircraft cut short the life of the first cosmonaut of the planet. But the people of the Earth will always remember Yuri Gagarin, his unusually kind smile.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Washing machine for dogs 11.03.2002

Spanish engineers Eduardo Segura and Andree Diaz created a dog washing machine in three years of intensive work. The machine, called "Lavacan" (from the Spanish words for "wash the dog"), lathers, washes and dries the animal enclosed inside in less than half an hour.

Like any washing machine, it has several programs for animals of different breeds and sizes, as well as for washing with insecticidal shampoo (this procedure takes longer than a simple wash). Along with washing, hydromassage is carried out. According to the inventors, dogs tolerate washing in the car well, many even like the procedure, and one dog fell asleep peacefully during drying. The inventors believe that their machine is also suitable for washing cats, but cats do not think so.

The industrial production of "Lavakan" has already been established, the car costs about 20 thousand dollars and is purchased mainly by professional breeders and dog beauty salons.
