Age determination of marine fish

Mousakitis: Gerry Mouzakitis

The ability to determine the age of fish is an important part in the study of fish biology. Age plays an integral role in the study of growth, mortality, reproductive strategies and the strength of a fish stock. The estimation of age structure is crucial to most forms of stock assessment world-wide.

Ageing of fish is based on the counting of growth zones (annuli) that appear on bony structures of fishes. The annuli that are used to age fish are equivalent to the counting of tree rings where every ring is equal to one year.

Fish can be aged using scales, otoliths, vertebrae, fin rays and opercula. Otoliths are most frequently used to determine the ages of marine fishes.
