Carbohydrate-rich diets are frequently used in the commercial farming of fish. However, fish do not appear to have an elevated capacity to clear a high load of glucose from their circulation. Special attention has been directed towards the study of the physiological responses to such carbohydrate-rich feeding. Skeletal muscles play a key role in glucose homeostasis in mammals, and exercise has a n ...

"A long standing question in the reproductive physiology of fish is how the metabolic status determines the onset of sexual reproduction, which often coincides with the start of reproductive migration. We hypothesize that swimming in that case triggers metabolic and hormonal changes critical for the induction of maturation. Studies on migrant fish like eel and salmon support the hypothesis that sw ...
