Modelling fishing‐induced evolution in pikeperch (Sander lucioperca) and vendace (Coregonus albula), Lake Oulujärvi, as template for ecosystem model

Journal of Fish Biology, EarlyView.
Abstract Fishing‐induced evolution can impact fish trait distributions, with previous studies highlighting declines in size and age at maturation. However, the effects on fish growth remain less understood, and different fishing methods may exert distinct selection pressures on populations.

Acclimation conditions and subsequent acute hypoxia challenges do not affect the frequency of erythrocyte nuclear segmentation in triploid brook charr Salvelinus fontinalis (Mitchill 1814)

Journal of Fish Biology, EarlyView.
Abstract Routine observations of blood smears have repeatedly shown that triploid fish have a greater proportion of erythrocytes with nuclear segmentation (ENS) than diploids; however, there is as yet no understanding of why this is the case and whether it affects erythrocyte function.

Effect of heterozygosity, ploidy and incubation temperature on post‐cranial axial skeletal meristics and deformities in Atlantic salmon (Salmo salar)

Journal of Fish Biology, EarlyView.
Abstract The teleostean post‐cranial axial skeleton is a highly specialized structure for an aquatic mode of life. However, there is limited knowledge regarding parental contributions, early‐life environmental impacts on its meristic variation and if reduced heterozygosity challenges its development.

Low genetic variation and strong genetic structure across a range of geographical scales in European smelt (Osmerus eperlanus L.)

Journal of Fish Biology, EarlyView.
Abstract Populations of anadromous European smelt (Osmerus eperlanus L.) are declining across its range with mitigation efforts for this ecologically important species hindered by a lack of demographic information. Here, mitochondrial DNA (mtDNA) and microsatellite analyses were used to describe historical and recurrent demographics for the species ...

A quantitative analysis of spermatogenesis in the trout, Salmo trutta fario

Cell and Tissue Research, 1983
The pattern of spermatogenesis was studied during an annual reprodutive cycle in adult male brown trout. The part of the testicular volume occupied by the nuclei of germ cells and of Sertoli cells, the lobular lumen and the extra-lobular space were measured. The number of germ cells was estimated by the total volume occupied by each cell divided by the

Habitat‐use strategies of young barramundi (Lates calcarifer) in a heavily modified landscape

Journal of Fish Biology, EarlyView.
Abstract Barramundi (Lates calcarifer) is a facultatively catadromous species that migrates between saltwater and fresh water to complete its life cycle. Modified riverine landscapes may limit these migratory paths and alter the environmental cues that migratory fish rely on to trigger migration.

First Report of ‘Soft Flesh’ Induced by the Parasite Kudoa thyrsites (Myxosporea) in Commercial Codfish From Norway

Journal of Fish Diseases, Volume 48, Issue 4, April 2025.
ABSTRACT Kudoa thyrsites is a myxosporean parasite that infects the skeletal muscle of various teleost fish species globally. Severe infections lead to ‘soft flesh’ in fish fillets, resulting in food spoilage and subsequent discard. While K. thyrsites has previously been identified in migratory Atlantic mackerel in the northern Northeast Atlantic Ocean,
