Lakescape connectivity: Mobile fish consumers link Lake Michigan coastal wetland and nearshore food webs

Ecosphere, 2023
In large lake ecosystems, fish movement between coastal littoral habitats such as wetlands and the adjacent open‐water nearshore represents an understudied but potentially important linkage supporting energy flow and fisheries production. We hypothesized

Strontium isotopes reveal diverse life history variations, migration patterns, and habitat use for Broad Whitefish (Coregonus nasus) in Arctic, Alaska.

PLoS ONE, 2022
Conservation of Arctic fish species is challenging partly due to our limited ability to track fish through time and space, which constrains our understanding of life history diversity and lifelong habitat use.

The Lifetime Migratory History of Anadromous Brook Trout (Salvelinus fontinalis): Insights and Risks from Pesticide-Induced Fish Kills

Fishes, 2022
Brook trout populations in Prince Edward Island, Canada, have experienced over 50 pesticide-related fish kills since the 1960s. Life history evaluation of large sea-run brook trout recovered following two fish kill events was compared with a reference ...

Contrasting population genomic structuring of northern pike (Esox lucius L.) in fresh- and brackish water environments: Implications for management and conservation. [PDF]

J Fish Biol
Abstract Understanding the factors that shape population genetic structure is crucial for advancing evolutionary studies and developing effective management and conservation strategies. The northern pike (Esox lucius L.) is a top teleost predator that inhabits fresh and brackish water environments in the northern hemisphere.

Development of a High-Resolution MNP Marker System for Aquatic Biodiversity Monitoring: A Case Study With Schizothorax prenanti in the Yangtze River. [PDF]

Mol Ecol Resour
ABSTRACT Effective monitoring of aquatic biodiversity is critical for conservation, yet current approaches such as mitochondrial COI barcoding and microsatellite markers exhibit limitations in resolution, sensitivity, and scalability, particularly for detecting low‐abundance or degraded DNA in mixed aquatic samples.

From Core to Edge: Habitat Signatures in the Otoliths of Genidens genidens in the Southwestern Atlantic Estuaries

Fishes
Understanding habitat use and connectivity in estuarine fishes is essential for effective conservation and management. In this study, otolith microchemistry was applied to investigate habitat use and connectivity of the estuarine catfish Genidens ...

Potential of Otolith Microchemistry to Distinguish Nursery Areas of Salmon within River Simojoki

Fishes, 2023
Draining into the northern Baltic Sea, River Simojoki is an important spawning river for Atlantic salmon. The present study aimed to preliminary explore the potential of analysing the elemental composition of otoliths to distinguish the within-river ...

Using Eye Lens Stable Isotopes to Identify the Rearing Origin of Fall Age‐0 Walleye (Sander vitreus)

Fisheries Management and Ecology, Volume 33, Issue 4, Page 775-783, August 2026.
ABSTRACT Isotope values in fish eye lenses may be useful in differentiating rearing origins. We compared eye lens isotopic values of fall fingerling age‐0 walleye (Sander vitreus) reared in a hatchery pond, a recirculating aquaculture system (RAS), and a natural lake. Using 10 fish per rearing source, we delaminated layers from one eye lens per fish to

Extent of mangrove nursery habitats determines the geographic distribution of a coral reef fish in a South-Pacific archipelago. [PDF]

PLoS ONE, 2014
Understanding the drivers of species' geographic distribution has fundamental implications for the management of biodiversity. For coral reef fishes, mangroves have long been recognized as important nursery habitats sustaining biodiversity in the Western

Movement Patterns of American Eels in an Impounded Watercourse, as Indicated by Otolith Microchemistry [PDF]

North American Journal of Fisheries Management, 2004
Abstract Otolith Sr:Ca ratios were used to determine migrational histories of American eels Anguilla rostrata in an eastern Canadian coastal stream that is impounded at the head of tide. American eels sampled from the estuary were smaller (41.0 ± 9.3 cm (mean ± SD), N = 324) and younger (ages 1–4) than those in a freshwater pond (65.0 ...
