Effects of ethanol preservation on otolith microchemistry [PDF]

Journal of Fish Biology, 2004
Solution‐based inductively coupled plasma‐mass spectrometry was used to examine the effects of exposure time to ethanol (0, 1, 3, 9, 27 and 81 days) and ethanol quality (ACS‐v. HPLC‐grade) on strontium (Sr) and barium (Ba) concentrations in sagittal otoliths of hatchery‐raised and wild‐caught young‐of‐the‐year walleye Stizostedion vitreum. No effect of

Using Isotopic Data to Evaluate Esox lucius (Linnaeus, 1758) Natal Origins in a Hydrologically Complex River Basin

Fishes, 2021
Otolith microchemistry has emerged as a powerful technique with which to identify the natal origins of fishes, but it relies on differences in underlying geology that may occur over large spatial scales.

Fish otolith microchemistry as a biomarker of the world's largest mining disaster

Science of The Total Environment, 2022
The Fundão dam collapse occurred in late 2015, resulting in the largest disaster in the world involving mine tailings, releasing at least 50 million m3 of iron ore tailings into the Doce river basin (Brazil). Studies realized along the Doce river after the disaster showed high concentrations of some elements above recommended Brazilian standards in ...

Particle backtracking improves breeding subpopulation discrimination and natal-source identification in mixed populations. [PDF]

PLoS ONE, 2015
We provide a novel method to improve the use of natural tagging approaches for subpopulation discrimination and source-origin identification in aquatic and terrestrial animals with a passive dispersive phase.

Fidelity to Natal Tributary Streams by Kokanee Following Introduction to a Large Oligotrophic Reservoir

Fishes, 2022
The WAC Bennett Dam was completed in 1968 and impounded the Upper Peace River to form the Williston Reservoir in north central British Columbia. In 1990, an enhancement project was initiated to stock Columbia River Kokanee (non-anadromous Sockeye Salmon;

Water and Otolith Chemistry: Implications for Discerning Estuarine Nursery Habitat Use of a Juvenile Flatfish

Frontiers in Marine Science, 2020
Variations in otolith elemental composition are widely used to reconstruct fish movements. However, reconstructing habitat use and environmental histories of fishes within estuaries is still a major challenge due to the dynamic nature of these coastal ...

Population Genomics Provides Novel Insights Into Evolutionary Relationships and Local Adaptation of Two Ecotypes <i>Coilia nasus</i>. [PDF]

Ecol Evol
Based on whole‐genome resequencing, we determined that the freshwater‐resident form (C. nasus taihuensis) is an ecotype of anadromous Coilia nasus, not a distinct subspecies. The two ecotypes diverged approximately 4.6 thousand years ago, coinciding with the formation of Tai Lake.

Early Life History and Recruitment Processes of a Tropical Anguillid Eel Anguilla marmorata to the Pacific Coast, as Revealed by Otolith Sr:Ca Ratios and Microstructure

Biology, 2022
Recent progress in otolith microchemistry especially in strontium:calcium (Sr:Ca) ratios has revealed significant features of life histories in fishes. A catadromous eel, Anguilla marmorata, has the widest distribution among anguillid eels throughout the

Revealing Population Connectivity of the Estuarine Tapertail Anchovy Coilia nasus in the Changjiang River Estuary and Its Adjacent Waters Using Otolith Microchemistry

Fishes, 2022
The estuarine tapertail anchovy, Coilia nasus, is a migratory fish with high economic value in China. We collected fish from the Changjiang River (the Yangtze River) estuary, the Qiantang River estuary, and the southern Yellow Sea, and studied their ...

Chemistry and shape of anadromous Alosine otoliths show extent of spawning population intermixed in a shallow wind-dominated estuary

Frontiers in Marine Science, 2015
The Alewife Alosa pseudoharengus and Blueback Herring A. aestivalis are highly migratory coastal species of the NW Atlantic, and species of concern due to continued low abundance.
