Perch fish generally have a lifespan of 10 to 12 years in the wild, although some can live for up to 15-20 years in ideal conditions. Their lifespan and growth rates can vary based on habitat, with some reaching maturity in 2–4 years (males) or 4–6 years (females).
Rougheye rockfish are deepwater fish found in the North Pacific. They can live for over 200 years. They are unique among their relatives, as many other rockfish can only live up to 11 years.
A relatively slow swimmer, yellow perch are an important prey for many predator fish like walleye, bass, northern pike and muskellunge. Life cycle: With a short life span, lasting about seven years, yellow perch reach maturity and begin reproducing at age 2 or 3.
Scientists specifically assess the age and growth rates of fish species by studying fish ear stones, called otoliths. Otoliths reveal the ages of individual fish, almost like counting the rings in a tree.

The tubeworm Escarpia laminata that lives in deep sea cold seeps regularly reaches the age of between 100 and 200 years, with some individuals determined to be more than 300 years old. Some may live for over 1,000 years.
Methuselah (captured 1938; born as early as 1922) is an Australian lungfish residing at the Steinhart Aquarium. She is known for being the oldest living fish in captivity as of 2023.
