Approach the Mechanism of Energy Supply in Tilapia (Oreochromis mossambicus) after Acute Cd Ezposure
1 Introduction Heavy metals, including cadmium (Cd), exert a wide range of pathological effects on fish and other aquatic organisms 1. Besides, Cd is a non-essential element that can have severe toxic effects on aquatic organisms when present in excessive amounts. On the other hands, it was a stressor to induce stress responses that like as induce cortisol secretion and enhance blood glucose increasing2. Generally, animals always increase metabolism rate to resistant the stress. The past study has found that GR cells are initially stimulated to provide prompt energy for neighboring MR cells that trigger ion-secretion mechanisms. Several hours later, the liver begins to degrade its glycogen stores for the subsequent energy supply during the fish transfer from FW to SW 3. Therefore, it is interesting to know how about the energy supply upon the Cd exposure. The aim of this study was to compare the energy metabolism between gill and liver in tilapia upon acute cadmium exposure.
