Resumen:
Growth rate is the most important trait in aquaculture. Postembryonic muscle growth depends on proliferative myogenic precursor cells (MPCs). Refeeding after nutrient starvation is followed by a phase of accelerated growth known as compensatory growth. Although fish show a particularly robust capacity for catch up growth, the biological mechanisms and the role of MPCs in this process remain elusive. To give insight into the basis of this process, pools of 200 mg fishes were set: a control group was continuously fed and a treated group was starved for 2 weeks. At 7 and 10 days after the start of the experiment fishes received an intra peritoneal injection of 5-ethynyl-2?-deoxyuridine in order to track and label MPCs. Both weight and length of starved fishes were significantly lower than controls (p
