TLDR
The sagittal otolith of 348 species, belonging to 99 families and 22 orders of marine Teleostean fishes from the north and central eastern Atlantic and western Mediterranean were described using morphological and morphometric characters, providing information that complements the characterization of some ichthyologic taxa.Abstract:
The sagittal otolith of 348 species, belonging to 99 families and 22 orders of marine Teleostean fishes from the north and central eastern Atlantic and western Mediterranean were described using morphological and morphometric characters. The morphological descriptions were based on the otolith shape, outline and sulcus acusticus features. The morphometric parameters determined were otolith length (OL, mm), height (OH, mm), perimeter (P; mm) and area (A; mm 2 ) and were expressed in terms of shape indices as circularity (P 2 /A), rectangularity (A/(OL×OH)), aspect ratio (OH/OL; %) and OL/fish size. The present Atlas provides information that complements the characterization of some ichthyologic taxa. In addition, it constitutes an important instrument for species identification using sagittal otoliths collected in fossiliferous layers, in archaeological sites or in feeding remains of bony fish predators.read more

Environmental biology of fishes
TL;DR: A large number of fish species have been recorded with low numbers of eggs and larvae, and it is unclear how these numbers have changed over time or what causes these fluctuations.

Relationships between otolith size and fish size in some mesopelagic and bathypelagic species from the Mediterranean Sea (Strait of Messina, Italy)
TL;DR: The length-weight relationships and the regressions between otolith size (length and width) and fish length of some mesopelagic and bathypelagic fishes living in the central Mediterranean Sea were provided.

Enigmatic ear stones: what we know about the functional role and evolution of fish otoliths.
TL;DR: It is suggested that the advent of solid otoliths may have initially been a selectively neutral ‘by‐product’ of other key innovations during teleost evolution and the teleost‐specific genome duplication event may have paved the way for diversification in otolith shape.

TL;DR: The predation on the high-energetic food as mesopelagic and bathypelagic fishes during the pre-spawning and the spawning period may bring an energetic advantage in tuna metabolism and gonadal maturation.

TL;DR: TheBonitos constitute the scombrid tribe Sardini, consisting of eight species placed in five genera, and are more closely related to the bonitos than to any other scombrids.

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.

Stock Discrimination Using Otolith Shape Analysis
TL;DR: There were highly significant differences in otolith shape among most of the cod samples, but shape also differed among ages, sexes, and year-classes, indicating that growth rate contributes more variation to regional differen...
