High pre-slaughter mortality rates of Atlantic salmon (Salmo salar L.) are a reoccurring
welfare issue and economic burden in aquaculture. Sudden death immediately prior to …

Investigating the mechanisms that fish employ to maintain homeostasis in their everyday life
requires measurements of physiological and behavioural responses in the field. With …

Introduction: Although dozens of studies have attempted to determine the metabolic cost of
osmoregulation, mainly by comparing standard metabolic rates (SMR) in fish acclimated to …

At reduced salinities nearing isosmotic conditions, marine fishes experience reduced
osmotic gradients between body fluids and the surrounding water, which should lower …

Substantial increases in cardiac output (CO), stroke volume (SV), and gastrointestinal blood
flow are essential for euryhaline rainbow trout (Oncorhyncus mykiss) osmoregulation in …

Salmonid ventricles are composed of spongy and compact myocardium, the latter being
perfused via a coronary circulation. Rainbow trout (Oncorhynchus mykiss) acclimated to sea …

AMP-activated protein kinase (AMPK) serves as a major regulator of cellular energy
metabolism by activating ATP production pathways and blocking ATP consumption …

Anadromy is a distinctive life-history strategy in fishes that has evolved independently many
times. In an evolutionary context, the benefits of anadromy for a species or population must …

The fish gut is responsible for numerous potentially energetically costly processes, yet little
is known about its metabolism. Here, we provide the first in vivo measurements of aerobic …

This chapter summarizes the form, function, and control of the blood vasculature in fish. It
starts with a general overview of the gross anatomy of the vascular system. We then turn to …
