Developing Pacific molluscs produce their own carbohydrates

Animals that develop within an egg, must rely on the egg yolk for nutrition for healthy development. While we have known that proteins and fats in the egg are important for development, the role of carbohydrates in the development of molluscs is a bit vague. A new study published in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology examined the role of carbohydrates in the development of Pacific […]

Chronic stress causes muscle loss

Researchers have known that chronic stress has many negative health effects that can impair normal growth. The impact of stress on skeletal muscle specifically is less understood. For this reason, researchers at Universidad Andres Bello in Chile explored the effects of stress induced by overcrowding in fine flounders (Paralichthys adspersus). Their results were published this month in American Journal of Physiology – Regulatory, Integrative and Comparative Physiology.  After just four weeks of […]

Importance of diet to the physiology of farm-raised fish

Image of a fish farm by Vera Kratochvil [Public domain], via Wikimedia Commons Fish farming, i.e. aquaculture, has increased about 6.2% between the years 2000-2012, according to the Food and Agriculture Organization of the United Nations. Fish farms are highly dependent on fish meal as well as fish oil as nutrients for the growing fish. Although rates of farming have increased, the supply of fish meal and oil are predicted […]
