Fish Age Judgement Method
The common way to determine the age of a fish was as follows: ** 1. Scale Technique ** 1. ** Principle ** - Fish scales were composed of horniness and calcium, and grew larger as the fish grew. Its growth is affected by season, temperature, food and other factors. In the growing season (spring and summer), it grows fast, and the scales add new cell layers quickly, forming a wide and light-colored growth zone; in the non-growing season (autumn and winter), it grows slowly, forming a narrow and dark rest zone. A pair of growth zones and rest zones formed the annual rings. 2. ** Operation and application ** - Take a scale of a fish and observe it under a microscope or magnifying glass. Count the number of black ring-shaped stripes (growth rings) on the scale and add 1 to the actual age of the fish. This method was simple and did not affect the survival of the fish. It was suitable for most scaly fish species. In the 1950s, China began to use this method to determine the age of common economic fish such as carp, grass carp, and carp in rivers and lakes. Later, it was also used to study the age of important economic fish such as yellow croaker, yellow croaker, and hairtail in the ocean. However, the scales may be damaged or fallen off, the growth rings may be irregular or unclear, and there may be regeneration or replenishment phenomena, which will affect the accuracy. During the operation, healthy, complete, and representative scale samples shall be selected, and standardized processing and reading methods shall be adopted for verification. ** 2. Otolith Method ** 1. ** Principle ** - Otolith is located in the inner ear of fish and is composed of calcium carbonite and organic matter. Its growth is affected by factors such as season, temperature, and food. In the growing season, the otolith increased the new cell layer quickly, forming a wide and light-colored growth zone; in the non-growing season, it was slow, forming a narrow and dark-colored rest zone. A pair of growth zone and rest zone formed the annual ring. 2. ** Operation and application ** - The age of the fish was estimated by counting the growth rings on the otolith. The method was relatively simple to operate and was suitable for scaleless or small fish species, which could reflect the true age. In China, it was mainly used to determine the age of large-scale economic fish and deep-sea fish such as tuna, sharks, and codfish. However, the otolith may be damaged or missing, the growth rings may be irregular or unclear, and there may be invisible or false growth rings. When using it, healthy, complete, and representative otolith samples should be selected, and standardized processing and reading methods should be used for verification. ** 3. Bone Technique ** 1. ** Principle ** - Using the growth rings formed on the hard bone structures of fish (such as spine, back spine, chest spine, abdominal spine, ribs, etc.) to calculate age. 2. ** Operation and application ** - It is suitable for scaleless or small-scaled fish species such as catfish and salmon. ** 4. Length-frequency Method ** 1. ** Principle ** - The age of the fish was calculated by the length distribution characteristics of the fish. In addition, when the scales were not clear, the age of the fish could also be estimated based on the vertebrae, operculum, and dorsal fin. For example, flatfish could use the vertebrae, salmon could use the operculum, sharks could use the dorsal fin, and large and small yellow croakers could use otolith to calculate the age. There were also methods to estimate the age of a fish by observing its appearance, and there was also a saying that the age of a fish could be determined by its diet, but the latter two methods were relatively less scientific and accurate.

Qianlong Tongbao's Value Judgement Method
Qianlong Tongbao's value judgment method mainly had the following points: 1. ** Layout differences **: The value of different typographies varies greatly. For example, the Shandilong edition had a higher collection value than the ordinary edition. The right half of the word "clamp" in the Shandilong edition was smaller, the word "Yong" in the word "Tong" was smaller than the ordinary edition, the first stroke of the word "treasure" was not prominent, and the word "mountain" was below the word "dragon". The Zhengzi Long edition was also more popular and had a higher value. 2. * size **: For example, Qianlong samples with a diameter of 27mm or more are more valuable than ordinary size. 3. ** Money Bureau's difference **: The value of Qianlong Tongbao cast by different money boards such as Baoquan Bureau and Baoyuan Bureau is different. Baoji Bureau's wide-edge version has a higher value. 4. ** Special edition **: For example, the value of the collection of mother carvings is relatively high; the palace coins such as Qianlong Tongbao and Taiping are relatively rare, and their collection value and economic value are very high. 5. [Appearance: Appearance is also an important factor that affects value. A good appearance is more valuable.] 6. ** Patterned condition **: The real Qianlong Tongbao will naturally form patchy over a long period of time. The quality of the patchy will also affect the value judgment. Watching " Safe Entry " wasn't enough. Everyone, please click to read the novel!
Fish Age
Different species of fish had very different ages. There were more than 36000 known fish species in the world, and new fish species were constantly being discovered. Among the known fish species, the sleeping shark is the world's longest known vertebra, with a lifespan of more than 400 years. The largest one can reach 502 centimeters in length and is between 272 and 512 years old.(120-year-old measurement error); the average life expectancy of the Aleutian rockfish is 20.5 years, and the longest can reach 205 years; the life expectancy of the Atlantic roughy can reach 149 years; the life expectancy of the large-mouthed bull fish is at least 112 years; the members of the sturgeon family, such as the white sturgeon and the European sturgeon, can live up to 100 years or even longer; the life expectancy of the giant bone tongue fish can reach 50 years; and the life expectancy of the Atlantic codfish can exceed 25 years. If the four major Chinese carps (silver carp, bighead carp, grass carp, and black carp) were allowed to grow without interference, they could generally live for 5 - 8 years. Some could live for 10 years, and very few could live for 20 years. Carp could live up to 40 years, and in extreme cases, it could live up to 100 years. Catfish also had a longer lifespan. The common methods to determine the age of a fish were to look at the scales to determine its age (according to the "annual rings" on the scales, the wide thin slices formed by rapid growth in spring and summer were sparse, and the narrow thin slices formed by slow growth in autumn and winter were tightly arranged. The boundary between the two was the annual ring), to measure the length and weight of the fish to determine its age, to look at the appearance of the fish, and to determine the age of the fish by the food it ate. In addition, one could also use the spine, operculum, otolith, etc. of the fish as observation materials to determine the age. The method was similar to observing fish scales. They both used the "growth rings" formed by the fish at different growth periods to determine the age. The novel "Watching the Moon on Fish Island" is equally exciting.

The age of a fish and the age of a human
A fish's one year old was roughly equivalent to a human's eighteen years of age. It was in the teenage years of humans. Different types of fish had different lifespans. Take goldfish as an example. The infant period, month (possibly expressed as month age), one year old, and old age of goldfish roughly corresponded to the different stages of human growth. However, this was only a rough comparison. The corresponding relationship between the age of different species of fish and human age might be different.

Method to determine age
The method to determine age was as follows: 1. Biological methods: determine the age by detecting the biological characteristics of the human body, such as detecting bones, teeth, skin, etc. This method is often used in archaeology, archaeology, and medical research. In the field of agricultural animals, the age can also be roughly estimated according to the appearance or the number of horns of the cow. The most reasonable and accurate method is to check the teeth, especially the occurrence of the lower teeth, tooth replacement, tooth wear, shape, direction, etc. 2. ** legal method **: In some cases (such as legal cases), the age can be determined through documents such as ID card, birth certificate, passport, etc. 3. ** Calendar Method **: Calculating age according to the calendar (such as the solar calendar or the lunar calendar), often used in daily life and work. In addition, there were some special ways to determine age, such as by looking at the hand, but this method may lack extensive scientific evidence. Different age determination methods may have some errors. If you want an accurate age, it is best to use multiple methods to verify it. The novel "The Lost Seventeen" is equally exciting.
