One way is to look for publication dates or copyright information printed inside the comic. Sometimes, you can also check for specific editions or reprints that might give you a clue.

Look for any metadata or settings related to your private story. Sometimes, there might be a specific field indicating when it was made. Also, check the file properties if it's saved as a document or file.

There were several common ways to determine the age of a fish: 1. Scale Technique: - "Principle: Scales are composed of horniness and calcium. They grow as the fish grows, but their growth rate is affected by factors such as season, temperature, and food. In the growing season (spring and summer), the fish grew fast and the new cell layer of the scales increased quickly, forming a wide and light-colored growth zone; in the non-growing season (autumn and winter), the growth was slow and the new cell layer of the scales increased slowly, forming a narrow and dark rest zone. A pair of growth zones and rest zones formed an annual ring. - Operation: Strip a scale of the fish and observe it under a microscope or magnifying glass. Count the number of black circular stripes on the scale and add 1 to the actual age of the fish. This method was simple to operate and did not affect the survival of the fish. It was suitable for most scaly fish species, but the scales may be damaged or fallen off, the growth rings may be irregular or unclear, and there may be regeneration or replenishment phenomena. When using it, healthy, complete, and representative scale samples should be selected, and standardized processing and reading methods should be used. Then, they should be corrected and verified. 2. ** Otolith Technique **: - [Principle: Otolith is composed of carbon dioxide and organic matter. It is located in the inner ear of the fish. Its growth rate is affected by factors such as the season.] In the growing season, the new cell layer of otoliths increased quickly, forming a wide and light-colored growth zone; in the non-growing season, the new cell layer increased slowly, forming a narrow and dark resting zone. A pair of growth zone and resting zone formed a ring. - [Operation: Estimated the age of the fish by counting the growth rings on the otolith.] This method was relatively simple to operate and was suitable for scaleless or small scale fish species. It could reflect the true age, but 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, it was also necessary to select suitable samples and conduct verification. 3. ** Bone Method **: 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 the age. Usually, more detailed processing and analysis of the hard bone structure is needed. It is suitable for scaleless or small fish species, such as catfish and salmon. 4. ** Length-frequency method **: Using the length distribution characteristics of fish to calculate the age of fish. 5. ** Inferring based on appearance (experience method)**: For example, some people who often come into contact with fish, such as the chef of Shunshui Fish Restaurant, can infer the approximate age of the fish by looking at the appearance of the fish through long-term understanding of the characteristics of each fish. However, the accuracy of this method is relatively poor. The novel "Watching the Moon on Fish Island" is equally exciting. Everyone is welcome to click and read it!
