Age assessment in European sturgeon: chap. 23

Abstract : Age determination is a key tool in population dynamics for acquiring data on age structure and cohort strength. In the case of a protected species, the method is required to have no adverse effects on the fish. A method using a thin section of the first pectoral fin ray has been set up on Acipenser sturio according to these prerequisites, and has been validated. The main limitations concerning old fish or fish held in captivity are discussed.
