Nitrogen excretion and oxygen consumption under severe hypoxia in siluriform fishes from the Amazon

Journal of Fish Biology, EarlyView.
Abstract Siluriform fishes collected from the Rio Negro and Rio Solimões proved to be highly resistant to aquatic hypoxia. In all four species analysed in this study, aquatic oxygen consumption significantly decreased from normoxic levels at water PO2 values near 1 kPa. Air‐breathing activity was observed only in Sturisoma sp. (Rio Negro).

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.
