名詞 定義　
ageing The process of determining the age of a fish or population of fishes. A fish that is less than 1 year old (counted from time of spawning by its parents) is a subyearling, or zero-age. A yearling fish is more than 1 year and less than 2 years old. Ages may be expressed as years or as years with a + sign, e.g. 3+ is a fish in its fourth year of life. Strictly, this term should be used only for the process of becoming older and the associated changes in an individual.
