TLDR
In this article, the presence of diurnal rhythm in otolith formation was examined physiologically in the goldfish, Carassius auratus, and the 45 Ca uptake by otoliths indicated that the formation slowed down or stopped at sunrise and resumed in 3 hours.About:

Microstructure of Fish Otoliths
TL;DR: Otolith microstructure examination has found an increasing number of applications in recent years, but few workers have critically assessed the assumptions upon which the age and growth of the structure is based.
Journal ArticleDOI
Circadian rhythms and feeding time in fishes
TL;DR: Fish that are fed always at the same time of day show typical pre-feeding activity and blood levels of some nutrients and hormones also show peaks or troughs at the time of feeding, but whether these are pre- feeding or post-prandial events is not clear.

Somatic Growth Effects on the Otolith–Fish Size Relationship in Young Pond-reared Striped Bass, Morone saxatilis
David H. Secor,John Mark Dean +1 more
TL;DR: Somatic growth rate of pond-reared larval and juvenile striped bass, Morone saxatilis, influenced the relationship between otolith size and fish size, and slower growing groups of individuals had large sizes.
Journal ArticleDOI
Review of the growth regulation processes of otolith daily increment formation
TL;DR: Environmental conditions, transmitted through the physiology of fish, affect the otolith growth rate (increment width) but increment periodicity may be disrupted only in extreme cases of physiological stress.
Journal ArticleDOI
Regulation of calcium and strontium deposition on the otoliths of juvenile tilapia, Oreochromis niloticus
TL;DR: In this paper, radioisotopes of calcium and strontium were used to test for a relationship between the environmental concentrations of each element and their respective deposition rates on the otolith.

Fish Otoliths: Daily Growth Layers and Periodical Patterns
TL;DR: The early-stage annual rings in otoliths from some cold-temperate fish consist of thin growth bands, the number of which corresponds to that of the days in a year, which indicates that growth takes place by daily increments.

A simplified method of sample preparation for determination of tritium, carbon-14, or sulfur-35 in blood or tissue by liquid scintillation counting
TL;DR: In this article, a safe method has been described by which animal fluids, including whole blood, or animal tissues (including whole bone), may be solubilized into colorless, stable liquid scintillation samples and measured for content of tritium, sulfur-35, or carbon-14 with good absolute efficiency and without phosphorescence.

Molecular structure and composition of fish otoliths
TL;DR: Oxygen and carbon isotope data indicate that the aragonite is formed close to isotopic equilibrium with the sea, which is surprising, because seawater has no direct access to the inner ear where the otolith orginates.
Daily growth increments in otoliths from larval and adult fishes
TL;DR: Daily growth increments have been found in otoliths of fish larvae, and the annual marks detected in the conventional way were shown to contain about 365 daily units.

Triton X-100 scintillant for carbon-14 labelled materials.
TL;DR: Touluene/Triton X-100 liquid scintillant has been found to possess excellent characteristics for the counting of a wide variety of carbon-14 labelled compounds and shows considerable resistance to quenching effects from aqueous samples, particularly aqueously acids.
