How to Give First Aid to Fish Fry That Have Fainted During Transport
During transport, fish fry often faint and "turn belly-up" because excessive jolting drains too much of their strength, and if they are not rescued in time this can very easily cause their death. Here is an effective and simple bare-handed first-aid method: when you find that the fry have fainted and turned belly-up, immediately place them in clear water at a temperature of 10°C--20°C, in a wind-sheltered, sunny spot, and frequently splash water into the water body so that the spray falls evenly on the fish's belly, which can restore the fry to normal. The splashing frequency should be close to the breathing rate of the fry.

South Korea Produces Its First Somatic Cell Cloned Pig
South Korea's CHAO Pharmaceutical and the research group of Professor Kim Jin-hwe at Gyeongsang National University's College of Agriculture jointly carried out South Korea's first pig cloning project. Through this project, two cloned pigs were successfully born. The cloned pigs were born on July 14, 2002, using the somatic cell cloning method. The world's first successfully cloned pig was born in March 2000 at the PPL research institute in the United States. The research team now plans to develop genetically modified pigs by adjusting genes.

What varieties are first-grade superior varieties of apricots for kernel use?
1. Longwangmao Among the apricot varieties for kernel use currently mainly cultivated in production in China, only Longwangmao is first-grade, and it is called "Longhuang Big Almond" internationally. The fruit is oblate, with an average single fruit weight of 18 g and a maximum of 24 g; the skin is orange-yellow and the flesh is thin; the stone is free. The kernel rate is 17.5%, and the dry stone weight is 2.3 g. The kernel yield is 37.6%, and the average dry kernel weight is 0.8-0.84 g. The kernel is flat and plump, conical with a flat base; the kernel skin is brownish-yellow, and the kernel flesh is milky white, fragrant and crisp in taste, with a slight bitterness. The average yield per tree at 5-6 years old

How do you prune Schisandra chinensis? First, understand its growth habits
After wild Schisandra chinensis is cultivated artificially in farmland, in order to control tree vigor, avoid excessive overlap of branches and leaves, and prevent branches from tangling with each other, it should be pruned reasonably according to the growth habits of Schisandra chinensis. This makes the fruiting branches evenly distributed on the trellis surface, improves ventilation and light penetration, improves the field microclimate, enhances disease resistance, reduces nutrient consumption, promotes flower bud differentiation, and increases yield. 1. Heading back In the same year of sowing, Schisandra chinensis can grow to about 20 cm, and tall ones can reach more than 30 cm. Regardless of whether the seedling is tall or short, large or small, there should be 2 to 4 plump buds at the base

The world's first cloned dog has been born
South Korean scientist Hwang Woo-suk revealed in the recently published issue of Nature that his research team successfully produced the world's first cloned dog, Snuppy. Cloned dogs have always been a difficult challenge in the field of cloning technology. The reason is that dogs have only 2 estrus cycles per year, and waiting for a dog to ovulate naturally is the only way to obtain its eggs. Moreover, when a dog ovulates, the eggs released by the ovaries are at an early stage of development, and only mature at the end of the fallopian tube, so successfully extracting high-quality dog eggs is quite difficult. Cloned dogs are of great value in medical research

What is the best way to eat sea fish? Steaming or clear-simmering is the first choice
Sea fish contains a large amount of protein, vitamins, trace elements and minerals, and especially contains lecithin and a variety of unsaturated fatty acids. Lecithin helps remove plaques from blood vessel walls. Unsaturated fatty acids can lower blood lipids, improve the blood clotting mechanism, and increase high-density lipoprotein without increasing triglycerides, thereby reducing the formation of cardiovascular and cerebrovascular thrombi and preventing arteriosclerosis. It makes sense for people with high blood pressure to eat more sea fish. There are many ways to cook sea fish, including boiling, steaming, braising in soy sauce, clear-simmering, deep-frying and so on

Is the red-banded snake prone to illness? First, understand its disease resistance
The red-banded snake rarely gets sick in a suitable environment and is one of the varieties with a relatively low mortality rate among artificially bred species. It has strong vitality, which is also the main reason people breed this snake in large numbers. However, this snake often suffers from stomatitis after hibernation or shortly after emerging from dormancy. Disinfection should be strengthened, and isolation and treatment should be carried out promptly to prevent mutual infection. Snake enclosures and snake dens should be kept clean and dry during the peak summer season and the rainy season. Once the environmental humidity reaches above 85%, this snake is prone to fungal spot disease. This disease poses the greatest harm to this snake, no less than the severity of pneumonia

What to Do If a Dog Has Heatstroke? Symptom Recognition and First Aid
Dogs are very intolerant of heat, because dogs do not sweat, and they will not stop activity just because of heat; a dog's body cannot regulate its own temperature, and a dog will not take care of itself by rehydrating in time; a dog's sweat glands are all on its tongue, so seeing a dog stick out its tongue and pant means the dog is very hot and needs to drink water to cool down or settle down and stop activity; short-nosed dogs are more sensitive to heat than long-nosed dogs and have a harder time dissipating heat. A dog's normal body temperature should be 37.8°c--39°c. When body temperature reaches 40.65°c, internal organs begin to be damaged, and when body temperature reaches 41°C

Analysis of the reasons why first-time mother pigs refuse to nurse
For first-time mother pigs refusing to nurse, the solutions are: 1. Fix the nursing positions. After farrowing is complete, arrange the piglets around the lying sow with the weak ones in front and the strong ones behind, let them find the teats on their own, observe and adjust promptly, and after 2 to 3 days they will be fixed in an orderly arrangement. 2. Treat udder inflammation. Whenever the milk is plentiful and the piglets have just started sucking the teats, if the sow immediately lets out a scream, jumps up suddenly and even tries to bite the piglets, it means the sow has mastitis

The prerequisite for raising mink well is to first get the water quality right.
Ensuring water quality at a mink farm is the foundation for raising mink well. The water quality standard is based on the metabolism within the mink's body and the water content requirements of the products, and mainly covers the following aspects. 1. Cleanliness: clean drinking water has a turbidity below 3 and looks clear and transparent to the naked eye, with no impurities. If there are algae, mud, sand, or fine particles, the water will become turbid, which not only increases the specific gravity but may also breed bacteria and produce toxic and harmful substances. Therefore, selective treatment measures must be used, or the water must be boiled and filtered to remove residue before it can be used for @#@251@#@.
