Age, growth and utility of otolith morphometrics as a predictor of age in the wrasse Coris julis (Labridae) from the eastern Adriatic Sea

Scientia Marina, 2012
Age and growth of Coris julis were determined by examining sagittal otoliths belonging to fish sampled between November 2008 and October 2009 in the eastern Adriatic Sea (north-central Mediterranean Sea). A total of 1102 specimens (528 males, 487 females

Fish otolith biomineralization process: first investigations about organic matrix and growth of Triglidae (Scorpaeniformes) otoliths

Frontiers in Marine Science, 2015
Otolith formation involves rhythmic variations in the deposition and size of organic matrix framework and carbonate crystals, resulting in the formation of macroscopic translucent and opaque rings and microscopic zonations (growth increments) (Morales ...

Morphological Classification of the Sagittal Otoliths of Two Species of Sciaenidae Based on the Landmark Point Method

Fishes
Larimichthys crocea and Larimichthys polyactis, two commercially and ecologically important sciaenid species, are often morphologically confused (especially at the juvenile stage or for incomplete specimens), leading to limitations in traditional morphological taxonomic methods for accurate identification.

[Verification of the eclossion mark on the sagittal otolith of the larvae of Sardinella aurita (Pisces: Clupeidae)].

Revista de biologia tropical, 2005
The study of otolith in larvae is important to determine fish age and growth, essential parameters in the study and management of fisheries resources. In this study, the formation of the hatching mark in Sardinella aurita was verified on ichthyoplankton samples collected off southern Cubagua island, Venezuela, from May 1998 to January 1999. The embryos

A Case Study of Coilia nasus: Is There a Difference in Microchemical Signatures Between Left and Right Fish Sagittae?

Fishes
Owing to the asynchronous deposition of trace elements between paired left and right otoliths within individual fish, researchers must consciously and uniformly use only single otoliths (especially the left one) for microchemical studies.

Structural Irregularities in Sagittal Otoliths of Black Croaker (Cheilotrema saturnum) from Southern California

Bulletin, Southern California Academy of Sciences, 2010
Black croaker, Cheilotrema saturnum, is a sciaenid (Family Sciaenidae) common to the coastal nearshore ichthyofauna assemblage of southern California (Miller et al. 2008). Sciaenids, on average, are highly acoustic, both producing and receiving sonic vibrations via resonance through the swimbladder (Nelson 2006). Further acoustic sensing is facilitated

Spatiotemporal shape variation in sagittal otoliths of spotted grunter Pomadasys commersonnii in South African estuaries

African Journal of Marine Science
The morphological structure of fish otoliths is under dual regulation by genetic and environmental factors, and has been successfully used to aid stock delineation. This study examined whether differences in sagittal otolith shape outlines could be used to delineate potential stocks of the spotted grunter Pomadasys commersonnii (family Haemulidae) in ...

Ontogenetic and sex-related variations in otolith morphology and structure of thinlip gray mullet from a transitional environment in northern Italy

Frontiers in Marine Science
Otoliths are calcified structures present in the inner ear of fish involved in hearing and balance. Notwithstanding that their shape is species-specific, which is helpful for taxonomic identification, the intraspecific variability of shape and structures

Morphological variability of otolith organs in three congeneric Pagellus species

Oceanological and Hydrobiological Studies
Morphological features of sagittal otoliths in Pagellus acarne, P. bogaraveo, and P. erythrinus samples collected from the Aegean Sea were used to assess the variability both between Pagellus species and between otolith pairs employing scanning electron ...

3D sagittal otolith reconstruction from spherical Fourier descriptors

The shape of a fish's otolith varies according to its environment, genetics and life stage. To be able to analyse these shapes, standardisation is a crucial step. In this study, a protocol for standardising and aligning 3D reconstructions of the otolith was proposed, based on the extraction of Spherical Fourier Descriptors.
