FAQs
How old is a fish in one year? Fish age can vary depending on the species, but on average, many fish reach sexual maturity within their first year of life.
How do you count fish years? Fish years are typically counted by examining growth rings in their scales or otoliths (earstones). Each ring represents a year of growth.
What is the difference between fish years and human years? Fish years are not directly comparable to human years because fish age differently. Fish grow continuously throughout their lives, while humans have a more defined growth period.

How old is a 24-inch flounder? Similar to the previous answer, the age of a 24-inch flounder would depend on species and conditions, but it might be older than a smaller flounder.
How old is a 20-inch flounder? Again, the age of a 20-inch flounder would depend on species and conditions. It could be a few years old.
Do fish get bigger with age? Fish generally grow throughout their lives, so they tend to get bigger with age, but the rate of growth can vary.
How old is a 3-inch bluegill? A 3-inch bluegill is likely very young, possibly only a few months old.
What happens when you age fish? Aging fish involves examining growth rings in their scales or otoliths to determine their age. It provides insights into their growth rate and life history.
What was the color of the first humans? The color of the skin of the first humans is not definitively known, but it is believed to have been influenced by environmental factors.
How do we know we came from fish? We don’t come directly from modern fish. Instead, humans share a common ancestor with early fish-like vertebrates.
What fish are humans closest to? Humans are closest in evolutionary terms to other primates, such as chimpanzees and bonobos.
