Energy metabolism
of fishes (Guido van den Thilart) |
 |
Introduction
Energy is the prime requisite for life.
Most fishes are very plastic and can change their biochemical and structural make up within several days. Mechanisms of metabolic regulation and adaptation are studied with techniques like in-vivo NMR (nuclear magnetic resonance), calorimetry, cannulation, and cell cultures. Emphasis is placed on endocrine regulation of energy metabolism. Fishes are studied in relation to swimming, hypoxia, temperature, and ontogeny.
Keywords: swimming, hypoxia, fish feed, hormones, eel
