Estimates of Spawning Stream Contributions to an Imperilled Bull Trout Metapopulation Utilizing Otolith Geochemistry and Redd Counts

Ecology of Freshwater Fish, Volume 35, Issue 3, July 2026.
ABSTRACT Migratory fish species have experienced substantial declines throughout aquatic habitats, but actions to manage and conserve migratory species require a better understanding of the relative contributions of local populations to the metapopulation.

Interactive effects of strontium and barium water concentration on otolith incorporation in juvenile flounder Paralichthys olivaceus.

PLoS ONE, 2019
Although the relationship between the incorporation of an element into otoliths and the concentration of the element in water has been extensively investigated in many fish species, the interactive effects of multiple elements in water on the otolith ...

Genomic Insights Into Population Structure and Demographic History of White Anglerfish (Lophius piscatorius) Throughout Its Range

Evolutionary Applications, Volume 19, Issue 7, July 2026.
ABSTRACT Understanding population structure and clarifying species boundaries are essential for the sustainable management of exploited marine species. Although genomic resources for shallow‐water taxa have expanded rapidly, open‐water species remain comparatively understudied.

Is otolith microchemistry (Sr: Ca and Ba:Ca ratios) useful to identify Mugil curema populations in the southeastern Caribbean Sea?

Brazilian Journal of Biology
The aim of the present study was to evaluate the potential use of otolith microchemistry (Sr:Ca and Ba:Ca ratios) to identify silver mullet, Mugil curema, populations in Southeastern Caribbean Sea.

Evidence of a marine larval stage in coastrange sculpin Cottus aleuticus from a small coastal stream in California, USA, based on otolith strontium isotopes

Journal of Fish Biology, Volume 109, Issue 1, Page 588-593, July 2026.
Abstract Cottus aleuticus (coastrange sculpin) is one of two North American facultatively amphidromous sculpins, but habitat use during its planktonic larval stage is poorly documented. We analysed strontium isotopes (88Sr and 87Sr/86Sr) in otoliths of 10 adult C. aleuticus from a small coastal California stream.

Fish nearshore habitat-use patterns as ecological indicators of nursery quality

Ecological Indicators, 2021
Anthropogenic factors have been identified as major stressors of nearshore environments such as estuaries, sea grass meadows and mangroves. We hypothesize that aquatic organisms functionally dependent on these habitats as nurseries respond to ...

Limited Contribution of Hatchery‐Reared Pikeperch to a Wild Population in a Temperate Reservoir: Evidence From Otolith Microchemistry

Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
ABSTRACT Fish stocking is a common management practice used to mitigate the effects of overfishing and other threats to wild fish populations. It is mainly employed in freshwater ecosystems with complex and variable strategies (different timings, fish lengths and origins), making its effectiveness challenging to assess.

Tracing of aquaculture-escaped meagre Argyrosomus regius through otolith microchemistry

Journal of Sea Research, 2021
Escape incidents of farmed fish involve economic losses to fish farms, interactions with local fisheries and environmental impacts to coastal ecosystems. In order to ensure a sustainable aquaculture activity it is advisable to gather any kind of information about the escapees for further management strategies.

Revealing Ontogenetic Vertical Migration in Deep-Sea Grenadiers (Macrouridae) from the Southwestern Atlantic Through Otolith Microchemistry

Fishes
Understanding the life-history strategies of deep-sea fishes is essential for improving ecological knowledge and informing conservation efforts. Using otolith microchemistry, this study reconstructed the ontogenetic movement patterns of four grenadier ...

Preliminary indication of ontogenetic and spatial variations in the whole otolith isotopic and elemental signatures of Solea solea in the Gulf of Lions (NW Mediterranean)

Scientia Marina, 2012
Knowledge of fish life cycles is important for exploited species. In the Mediterranean Sea, catches of common sole (Solea solea) have fluctuated widely since the 1970s.
