Integrated Environmental Assessment and Management, EarlyView., 2023 Abstract In the Lake Koocanusa‐Kootenai River system (Montana, USA and British Columbia, Canada), selenium (Se) contamination has become an international concern and is suspected to contribute to the observed burbot (Lota lota) population collapse. Due to our limited ability to sample burbot in Lake Koocanusa for monitoring studies, we used a reference

Experimental validation of otolith-based age and growth reconstructions across multiple life stages of a critically endangered estuarine fish [PDF]
PeerJ, 2021 Background The application of otolith-based tools to inform the management and conservation of fishes first requires taxon- and stage-specific validation.

Temporal stability in the otolith Sr:Ca ratio of the yellow croaker, Larimichthys polyactis (Actinopterygii, Perciformes, Sciaenidae), from the southern Yellow Sea [PDF]
Acta Ichthyologica et Piscatoria, 2021 Otolith chemical signatures are sufficiently stable across time to allow for accurate stock classification. The classification of the southern Yellow Sea population for Larimichthys polyactis (Bleeker, 1877) and its connectivity with others from 1962 is ...

The prevalence of isolated otolith dysfunction in a local tertiary hospital
Journal of Otology, 2022 Objective: Patients with dizziness may present with symptoms of tilting, swaying, rocking, floating or with disequilibrium. This may be suggestive of an isolated otolithic dysfunction yet, there is little emphasis on this emerging clinical entity.

Utility of otolith weight to estimate age of Labeo bata (Actinopterygii: Cypriniformes: Cyprinidae) inhabiting the Ganga River [PDF]
Acta Ichthyologica et Piscatoria, 2018 Fish age estimation is essential for stock assessment, population dynamics, and fisheries management. The presently reported study was conducted to evaluate the relation between otolith weight and observed age in Labeo bata (Hamilton, 1822) inhabiting ...

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 ...

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 ...
