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

open access: yesJournal 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 ...

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

open access: yesJournal 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.

Fault Diagnosis of Chillers Based on Association Classification Rules

open access: yesZhileng xuebao, 2020
Most of the existing data-driven fault diagnosis methods are based on the black box model. Although their accuracy is high, it is difficult to explain the diagnosis process and result.

Short‐term performance responses of an intertidal fish to sedimentation and warming

open access: yesJournal of Fish Biology, EarlyView.
Abstract Climate change is altering coastal ecosystems by causing environmental fluctuations, such as increases in temperature and turbidity, which pose major implications for fish physiology and behaviour. Increases in temperature affect fish food intake, swimming capacity and oxygen delivery, while increases in turbidity can impair or enhance prey ...
