Identification of Lessepsian fish species using the sagittal otolith

Scientia Marina, 2012
Lessepsian species are marine organisms that enter the Mediterranean through the Suez Canal, a phenomenon that has dramatically increased in recent decades.

Differences in sagittal otoliths between two morid species: insights into the genus Physiculus (Moridae: Gadiformes)

Neotropical Ichthyology
Sagittae are widely used as tools in taxonomic and ecological studies of fishes, especially when external morphological characters are conserved or ambiguous. We analyzed morphological variation between two congeneric species of Physiculus: P.

Otolith Shape Variation Reveals a Preliminary and Novel Stock Structure Signal of Yellowtail Kingfish (<i>Seriola lalandi</i> <i>lalandi</i>) in Aotearoa New Zealand. [PDF]

Ecol Evol
Climate‐driven range expansion is reshaping marine species distributions and complicating stock assessment, including for Yellowtail Kingfish (Seriola lalandi lalandi) in Aotearoa New Zealand, which have recently expanded southward from a historically northern range.

Improving spine-based age estimation in centrarchid fishes using otolith-derived training sets. [PDF]

J Fish Biol
Abstract Nonlethal age determination is a priority in fish biology contexts where sacrifice is restricted, but estimates derived from nonlethally attainable structures tend to suffer from poor precision and accuracy relative to necessarily lethal, otolith‐derived estimates.

The effect of growth rate on otolith-based discrimination of cod (Gadus morhua) ecotypes.

PLoS ONE, 2021
Otolith shape has previously been used to identify ecotypes within the Icelandic cod (Gadus morhua) stock, using DST profiles to validate the results. Fish otolith shape variation has repeatedly been found to be largely determined by growth rate.

High prevalence of vaterite in sagittal otoliths causes hearing impairment in farmed fish [PDF]

Scientific Reports, 2016
AbstractThe rapid growth of aquaculture raises questions about the welfare status of mass-produced species. Sagittal otoliths are primary hearing structures in the inner ear of all teleost (bony) fishes and are normally composed of aragonite, though abnormal vaterite replacement is sometimes seen in the wild.

The morphology of Sagittal otoliths of Psettodes erumei (Bloch and Schneider, 1801) in the north of the Persian Gulf and Oman Sea [PDF]

بوم‌شناسی آبزیان, 2020
This study was conducted to investigate the morphologic and morphometric characteristics of sagittal otolith of Psettodes erumei in the north of the Persian Gulf and Oman Sea (Hormozgan Province).

Biometric relationships between body size and otolith size in 15 demersal marine fish species from the northern Brazilian coast [PDF]

Acta Amazonica, 2019
The relationships between fish size and sagitta otolith measurements were calculated for the first time for 15 species belonging to six families from the northern Brazilian coast.

Eco-morphology of sagittal otoliths in five Macrouridae species from Central Mediterranean Sea. [PDF]

BMC Ecol Evol
The increase in deep-sea exploitation and depletion related to fisheries activities has enhanced the importance of improving the knowledge about deep-sea species. Macrourids are an ecologically essential component of the bathyal community and are among the most abundant species in deep-sea environments worldwide.

Identifying sagittal otoliths of Mediterranean Sea gobies: variability among phylogenetic lineages [PDF]

Journal of Fish Biology, 2018
In this study, we describe and analyse the morphology of the sagitta, the largest otolith, of 25 species of Gobiidae inhabiting the Adriatic and north‐western Mediterranean seas. Our goal was to test the usefulness and efficiency of sagittal otoliths for species identification.
