The compensatory growth in juveniles of sea bass: gastric distributive pattern of molecules regulating metabolism.
The aim of this work was to investigate the distribution of regulative molecules in the stomach of juvenile Dicentrarchus labrax during compensatory growth, using immunohistochemical methods. Antisera against galanin, neuropeptide Y, ghrelin, leptin, and serotonin were used on fasted and refed D. labrax. The results show a characteristic distributive pattern for the sought molecules in fish refed after 35 days of fasting, with a high increased presence of both ghrelin and leptin.
