Revealing growth increments in fossil and modern otoliths with backscattered electron imaging

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 1, January 2026.
Abstract Otoliths, the functional earstones of teleost fishes, record growth in the form of microscopic increments, making them key archives of individual life histories. While increment analysis is commonly applied to modern otoliths, studies of fossil (Holocene) otoliths remain limited.

A Growing Degree‐Day Approach to Estimate Larval Hatching Sites Using Backtracking Simulations Without Larval Age

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 1, January 2026.
Abstract Walleye (Sander vitreus) are a valuable commercial and sport fishery in the North American Great Lakes, yet the relative contributions of known spawning sites to the Lake Erie population remain poorly understood. Backward‐in‐time Lagrangian particle tracking (backtracking) models have been widely applied to estimate larval origins, but the ...

Development of a High‐Resolution MNP Marker System for Aquatic Biodiversity Monitoring: A Case Study With Schizothorax prenanti in the Yangtze River

open access: yesMolecular Ecology Resources, Volume 26, Issue 1, January 2026.
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.

Discrimination of cod otolith shapes by two different Fourier methods

open access: yes, 2013
In this thesis we have applied Fisher’s discrimination method to cod samples to discriminate between cod originating from the coastal cod stock and cod originating from the arctic cod stock. The discrimination is based on Fourier coefficients extracted from cod otolith contours. We have optimized and compared two different Fourier methods of extracting

Invasive Eurasian Minnow Alters the Trophic Niche and Growth of Brown Trout in High‐Latitude Lakes

open access: yesEcology of Freshwater Fish, Volume 35, Issue 1, January 2026.
ABSTRACT Invasive species pose a major threat to aquatic ecosystems, particularly in high‐latitude lakes which are characterised by low biodiversity. In northern Europe, the Eurasian minnow (Phoxinus phoxinus) has colonised lakes historically dominated by salmonids, raising concerns about the impacts of invasive cyprinids on native fish populations and

Pelagic Larval Duration and Population Structure of a Widely Distributed Amphidromous Fish in the Indo‐Pacific Region

open access: yesEcology of Freshwater Fish, Volume 35, Issue 1, January 2026.
ABSTRACT Freshwater habitats in the Indo‐Pacific Islands are colonised by amphidromous fish, which undergo a marine larval phase while the rest of the life cycle takes place in the riverine habitat. These fish are mainly represented by Gobiiformes. Among these, Stenogobius genivittatus (Valenciennes, 1837) is widely distributed in the Indo‐Pacific ...

Widespread Phenological Shifts With Temperature in Alaska's Marine Fishes

open access: yesGlobal Change Biology, Volume 32, Issue 1, January 2026.
We investigated changes in the phenology of early life stages of fishes in the Gulf of Alaska and Bering Sea. Larval size on a standardized date was used as a proxy for larval developmental timing in spring. For most species, interannual variation in mean size‐at‐date was significantly and positively related to temperature, demonstrating widespread ...
