In addition, there are indigenous species of Fine-spotted pheasant, Far Eastern frog, red-spotted pheasant, and introduced species of river plover, Arctic erythrascus, silver pupa, Atlantic salmon, brown oysters, etc. are under experimental breeding.

It is typically compared with black strap molasses, and it possesses a musty, earthy aroma. Buckwheat Honey has been demonstrated to have higher levels of antioxidants than other honeys and was featured as an effective cough soother in a research project completed by Penn State College of Medicine. Buckwheat Honey's hearty, full flavor has several unique applications. Drizzle over some blue cheese, use in a homemade wheat bread.

Salmon culture
In the family of carps, they are known as crickets, and some are called crickets. They are collectively called crickets. It is called cold-water fish because it can be used for generations in low-temperature environments where other fish cannot breed. It is located in the vast sea and land areas north of 35 degrees north latitude, from the frigid zone to the temperate zone. For 200 years, people have developed salmonids, freshwater grazing and culture fisheries. Today, they have formed a world-famous cocoon fishery in more than 120 countries. In the 1950s, China started from the introduction of technology and developed rainbow trout farming. Since the 1980s, a single species of rainbow trout has developed into a breeding industry that breeds more than 20 provinces and regions, and people are beginning to realize the practical significance and development prospects of developing the breeding industry for the loss of cold water resources. First, the biological characteristics of carp Carp in the low temperature waters can only reproduce, grow, normal growth of the upper limit of the water temperature is very low, there is no obvious lower temperature biological characteristics than other fish. 1. The squid is a short-day-type fish, and it gradually matures in the autumn and winter in which the water temperature decreases day by day in natural light time. Gonadal development is sensitive to changes in light time, and changes in light can alter its maturation. People can use this feature to change their light to spawn at the desired time. 2. The breeding season is mostly from November to February of the following year, and the peak of reproduction is from December to January. In areas with long ice-sealing periods, some species breed in the spring when the stream begins to thaw the thawing food organisms. The breeding water temperature is below 8°C. 3. The upper limit water temperature for gonadal development, maturation, fertilization, embryonic development and juvenile hatching is 13°C. Over 13 °C gonadal development disorders, increased juvenile malformation rate. 4. There is no apparent minimum temperature for gonad maturation, fertilization, embryonic development, and juvenile hatching and development. At 0.5 °C water temperature, embryos can still develop and hatch normally. 5, after fertilization after embryonic development of up to 300 ~ 600 degrees, the completion of larvae development into the juvenile period after hatching film, just a hatching is juvenile fish, called hatching juvenile fish. 6. The optimum water temperature for growth is 8 to 20°C. Above 21°C, the metabolic intensity, feed efficiency, and disease resistance are reduced, and it will quickly die at 25°C. 7. There is no obvious minimum water temperature for growth, as long as the water does not turn into ice, it can feed and grow. 8. Lifelong inhabits the flowing water environment with high transparency and high dissolved oxygen. Due mainly to the above biological characteristics, Europe, the United States, and Japan have traditionally used carp as a cold-water fish. As a foreign language, China also quoted this term. In addition, squid also has the following biological characteristics. 9. There are two types of eco-groups, sea-fall and fresh-water, in most species. The seafall type is a sea freshwater migratory group. Freshwater species inhabit freshwater waters, but many species are also suitable for seawater life. Freshwater can also be implemented and mariculture can be implemented. 10. In addition to the humpback hemp hawa and the rock female salmon, the juvenile larvae of 0.2 to 15 grams of other bream fish have 7 to 12 larval ecchymosis (Parr?mark) marking the development of the juvenile fish. The residual groups of rivers in the Mashu haploid and the young females of the freshwater species will not disappear for a lifetime and will live forever in their naive form. 11. Carp fishes breed on the bottom of gravel rivers in freshwater streams. A few species spawn at the bottom of the gravel where the water flows. The large egg size, with a particle size of 4 to 6?, separates the eggs. 12. The squid is a ferocious fish, eating aquatic or near-water insects, shrimps, small fish, and frogs. Some large individuals feed on snakes and rodents. Sea-breeding species also feed on cephalopods, floating cavities, and intestines. After many species have been domesticated, artificial diets are preferred. Second, the type of catfish farming There are about 16 species of carp that can be completely artificially cultivated in the freshwater area of ​​the world. China's seawater breeding has achieved preliminary results, but it has not yet been promoted. At present, almost all of it is freshwater aquaculture. There are four kinds of supporting artificial culture techniques that have been generally cultivated or are being expanded. 1. Rainbow Trout: It is the first fish of the carps that was developed into aquaculture species. Up till now, there have been more than 130 years of breeding history. The breeding area has spread over 120 countries and regions. 2 years of sexual maturity, life can be repeated multiple times. The average annual water temperature of 12 °C, 2 kg of body weight up to 1 kg. The largest individual in the pond is 7 kg. Flowing pond culture, the output per square meter can reach more than 25 kg. The diseases that affect survival are mainly viral diseases and vibriosis. 2. Golden pheasant: Golden color system selected from the body color mutation of rainbow trout. Introduced from Japan in 1996, it has now become an excellent breed cultivated throughout the country. The biological characteristics, growth rate, and yield per unit area are similar to rainbow trout. Both food, fishing and ornamental value. Its golden body color is a dominant hereditary trait, which has important germplasm value for breeding scientific research. Because of its rich and elegant golden body color, the market price is higher than rainbow trout. 3, Yamagata: originated in Japan, was developed into a breeding species more than 50 years ago. It is one of the two most flavorful species of carp, and its market price is 3 to 8 times that of rainbow trout. Suitable for fishing in ponds and streams. 2 years of sexual maturity, breeding only once in life. The weight of the 2nd-instar fish is mostly 400-700g, and the largest individual is 900-1000g. Strong resistance to disease, generally not infected with viral diseases. At 22-25 °C water temperature, survival vigor and feeding intensity are better than rainbow trout. In 1996, the introduction of China, including full-scale human breeding, has matured and is currently expanding. 4, daylight white spotting: native to Japan, breeding history has been more than 50 years. 2 years of sexual maturity, life can be repeated multiple times. Suitable for fishing. Fish dishes are famous for sashimi, and the market price is 2 to 3 times that of rainbow trout. In 1996, China introduced an average annual water temperature of 12°C, 12-month-old body weight was 110-130 grams, and 2-year-old fish was 500-1,000 grams. The largest individual is more than 2000 grams. In the 0 ~ 4 °C environment, survival vigor, feeding intensity is better than rainbow trout. Eating artificial food that sinks, but also like to eat the bottom of the bait. Strong resistance to disease, basically no viral disease.
