Abstract: the muscle quality of Micropterus salmoides was studied under the “zero emission” pond system, and the muscle texture characteristics, amino acid content and fatty acid content of Micropterus salmoides were determined. The results showed that the muscle of “zero emission” pond reared Micropterus salmoides had good elasticity, rich and relatively balanced amino acids, rich in a variety of flavor amino acids, low saturated fatty acids, high monounsaturated fatty acids, polyunsaturated fatty acids, docosapentaenoic acids and docosahexaenoic acids. The muscle of “zero emission” pond reared Micropterus salmoides had good taste and nutritional value.

Key words: pond system, Micropterus salmoides, muscle quality
