Food intake of early juvenile western Baltic cod (Gadus morhua) during settlement transition

Journal of Fish Biology, EarlyView.
Abstract This study examines the gut contents of 203 early juvenile Atlantic cod [17–101 mm ± 18.48 mm standard deviation (SD)] from the Western Baltic Sea (ICES Subdivision 22) collected between 2020 and 2022. According to the observed prey (proportion of pelagic, intermediate and benthic items) in the cod guts, settlement transition from a pelagic to

Joint effects of elevated copper and temperature in juvenile Tambaqui exposed in black and white waters of the Amazon

Journal of Fish Biology, EarlyView.
Abstract This study aimed to investigate how exposure to elevated water temperature and metal concentration jointly affect the physiology of Amazonian fish. Aboard a research vessel in the Amazon, we evaluated the effects of water temperature (river T°C at 31.5°C and a + 4°C increase to 35.5°C) and of 3‐h copper (Cu) exposure (up to 600 μg/L) in ...

Aerobic scope is sustained through a heatwave in juvenile Atlantic salmon (Salmo salar)

Journal of Fish Biology, EarlyView.
Abstract Aquatic ectotherms are vulnerable to heatwave‐induced physiological stress, which arises from increased energy demands and reduced dissolved oxygen content in warmer waters. Understanding thermal physiology is critical for predicting how commercially and ecologically important populations could be affected by the increasing risk of rising ...

Intra‐annual energy density cycles of spring‐ and fall‐spawning Atlantic herring Clupea harengus reveal different reproductive allocation tactics

Journal of Fish Biology, EarlyView.
Abstract Atlantic herring Clupea harengus are total spawners that exhibit a large degree of reproductive plasticity and have substantial intra‐annual variation in their energetic condition. Recent research suggests that the species may be declining in energetic condition in the northwest Atlantic Ocean from the few historical records, but comparisons ...

The impact of isosmotic conditions on the metabolism and hypoxia tolerance of a reportedly oxyconforming teleost

Journal of Fish Biology, EarlyView.
Abstract Fish must manage the competing demands of ion balance and gas exchange across the gills – a physiological tension known as the osmorespiratory compromise. In dynamic estuarine environments, the osmorespiratory compromise may be exacerbated by variable salinity and periods of hypoxia that demand high respiratory work.
