Otolith microchemistry of the conger eel, Conger myriaster

Journal of the Marine Biological Association of the United Kingdom, 2002
Elemental composition and ontogenic change patterns of Sr and Ca were examined in conger eel, Conger myriaster, otoliths. Accumulations of the major elements of seawater, K, Mg, and Na, into otoliths were smaller than the accumulations of 19 other minor elements whose concentrations were determined.

Linking otolith microchemistry and surface water contamination from natural gas mining

Environmental Pollution, 2018
Unconventional natural gas drilling and the use of hydraulic fracturing technology have expanded rapidly in North America. This expansion has raised concerns of surface water contamination by way of spills and leaks, which may be sporadic, small, and therefore difficult to detect.

Otolith microchemistry shows natal philopatry of walleye in western Lake Erie

Journal of Great Lakes Research, 2020
Abstract Natal philopatry is important to the structure of fish populations because it can lead to local adaptations among component stocks of a mixed population, reducing the risk of recruitment failure. By contrast, straying between component stocks may bolster declining populations or allow for colonization of new habitat.

Fundulus grandis Otolith Microchemistry as a Metric of Estuarine Discrimination and Oil Exposure

Estuaries and Coasts, 2015
The Gulf killifish, Fundulus grandis, is a vital component of saltmarsh ecosystems and an indicator species for environmental impacts, because of strong site fidelity. Also, their otoliths can provide a record of environmental conditions because they are metabolically inert, grow continuously with the fish, and incorporate trace elements from the ...

Identifying stock structuring in the sandeel, Ammodytes marinus, from otolith microchemistry

Fisheries Research, 2018
Abstract Identifying the scale of population processes is important for sustainable fisheries management. In the North Sea, the lesser sandeel, Ammodytes marinus, is now managed as seven stocks delineated on the basis of biophysical model predictions of the limited scale of larval mixing.

Otolith Microchemistry Reveals Natal Origins of Walleyes in Missouri River Reservoirs

North American Journal of Fisheries Management, 2016
Abstract Reproductive habitats are vital for sustaining fish populations, but their location and relative natal contributions are often unknown or poorly understood. We used otolith microchemistry to examine natal origins of Walleyes Sander vitreus in Missouri River reservoirs (i.e., Lake Oahe, Lake Sharpe, Lake Francis Case, and Lewis ...

Otolith Microchemistry of Coastal Cutthroat Trout from the Marys and Willamette Rivers

Northwestern Naturalist, 2018
Abstract We sampled the water chemistry and otolith chemistry and structure of juvenile Cutthroat Trout collected in the Marys River and adults collected in the Willamette River to evaluate the potential to identify life-history variation in this population.

[Otolith microchemistry of tuna species: research progress].

Ying yong sheng tai xue bao = The journal of applied ecology, 2012
Microchemistry analysis of trace elements and isotopes in fishes' calcified substances is an emerging approach to analyze the population structure, life history, and migration environmental history of fishes. With the increasing improvement of the researches and applications of otolith microchemistry, this approach has been a good tool for studying the
