Comparison of otolith readability and reproducibility of counts of translucent zones using different otolith preparation methods for four endemic Labeobarbus species in Lake Tana, Ethiopia [PDF]
, 2019 The analysis of fish age data is vital for the successful conservation of fish. Attempts to develop optimal management strategies for effective conservation of the endemic Labeobarbus species are strongly affected by the lack of accurate age estimates ...

Aquatic Biology, 2015 Otolith carbon isotope δ13C values may provide temporally resolved diet proxies in fish. If otolith δ13C values reflect diet, isotope values from recent otolith and muscle tissue should correlate and known ontogenetic diet shifts should be reflected in ...

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.

Otolith Morphology and Population Discrimination of Triplophysa yarkandensis
Progress in Fishery Sciences, 2023 To study the classification, identification, and discrimination between different geographical populations of Triplophysa yarkandensis and explore the related otolith morphology and fish life history, this study statistically analyzed the morphological ...

Larval condition and growth of Sardinella brasiliensis (Steindachner, 1879): preliminary results from laboratory studies [PDF]
, 2003 Brazilian sardine, the most important resource along the southeastern Brazilian coast, presented great variations and declines in its stocks. The main factors contributing to this are: oceanographic structure changes; recruitment failures; excessive ...

Otolith δ13C values as a metabolic proxy: approaches and mechanical underpinnings
Marine and Freshwater Research, 2019 Knowledge of metabolic costs associated with maintenance, foraging, activity and growth under natural conditions is important for understanding fish behaviours and the bioenergetic consequences of a changing environment. Fish performance in the wild and

Glass eels and viruses – a lesson learnt from stocking the eastern German Baltic Sea coast
Transboundary and Emerging Diseases, Accepted Article., 2022 Abstract Concerns about Anguillid herpesvirus 1 (AngHV‐1) in European eels, especially due to stocking measures, is increasingly coming into focus and raises questions regarding disease monitoring and prevention. In the past, stocking of AngHV‐1‐positive eels into waters assumed AngHV‐1‐free has led to a rapid increase of infected eels in the wild. For

Aquatic Sciences and Engineering, 2020 The objective of this study was to determine the regressions between otolith sizes and shape indices vs. fish length, and weight of whiting, Merlangius merlangus (Linnaeus, 1758), from the Black Sea. Samples were collected randomly from commercial bottom

Otolith chemistry does not just reflect environmental conditions: a meta-analytic evaluation
, 2018 Fish otoliths are widely used to answer biological and ecological questions related to movements and habitat use based on their chemical composition. Two fundamental assumptions underlie otoliths as environmental tracers and proxies for reconstructing ...
