This study was conducted to investigate the effects of two extruded pellets on growth, feed utilization, body indices, chemical composition and flesh quality. Two hundred eel with mean body weight of 82.8 g were raised in indoor concrete tank for 5 months. The growth, feed conversion ratio and body indices were insignificantly affected by diets. The results of Chroma meter analysis showed that the apparent skin color was slightly influenced by diets. The post-thaw drip from muscle was reduced in the eel fed with the FRI self-produced pellets. Meanwhile, crude protein content of fillet was significantly higher in the FRI pellets fed eel than the fish fed with commercial pellets. The fatty acid composition of fillet was remarkably affected by dietary fatty acid composition. The concentration of total free amino acids in the muscle of the FRI pellets fed eel was significantly higher than that of the fish fed with commercial pellets, while the contents of flavor amino acids and carnosine were not affected by diets. The results of this study indicate that the flesh quality can be improved to a certain extension via modifying the formulation of extruded pellets.
