Hyperplastic and Hypertrophic growth of muscle fibers in nile tilapia(Oreochromis niloticus)

摘要：

　　Muscle growth in nile tilapia, Oreochromis niloticus was studied histological to identify and quantify muscle fiber hyperplasia and hypertrophy.Relationships of somatic growth were evaluated by length comparisons while muscle was assessed from cross-sectional area measurements of while muscle fiber in 63 nile tilapia ranging in size from post-hatching to 70 mm.The average cross-sectional fiber area increased from approximately 1.50 μm2 to 124.69 μm2 as the fish increased in size, indicating that hypertrophy plays an important role in growth.Hyperplastic fiber recruitment accounted for approximately 97.56% of muscle growth in recently hatched fish and gradually decreased with fish length.
