Description Otoliths are found in the membranous labyrinth
of the inner ear of teleost fish and serve mainly in
balancing the organism. They are composed of
calcium carbonate and are deposited rhythmically
as aragonite crystals within a protein matrix. They
have long been used in fish aging studies. Recently,
changes in the strontium (Sr): calcium (Ca) ratios in
otoliths have received increasing attention, as these
provide a method of reconstructing environmental
history of the fish. Strontium is a calcium analogue
sharing a similar crystal ionic radius and can
substitute for Ca in the aragonite lattice of otoliths.
