Abstract: Fish age determination is considered as the basis and premise of fish population ecology research and fishery resource assessment. At present, there is no unified standard for age determination in different fishes, thus usually several methods are combined and verified. The most widely used method is still the annual ring of hard tissues, which is based on the growth lines of calcified tissues such as otolith and scales. In recent past years, there have been some new developments in the use of fish-eye lenses for age determination, especially in cartilaginous fish. In this paper, the principle and application of age determination of different hard tissues (calcified tissue and crystallite) of fish are systematically reviewed, the latest progress in the field of age determination of hard tissues of fish is described, and the prospect of the development and improvement of age determination in fish is prospected, aiming to provide reference for the research and application of growth and age determination of fish.
