TBA analysis showed 0.01% of TP had evident antioxidation on lipids from fish meat, and TBA increased with the TP concentration accretion presenting an unlinear relation. The effects of antioxidation of 0.03% and 0.07% of TP were close, thus, the best choice is 0.03% in practical application.5. 93 bacteria strains were isolated and categorized into several spoilage bacteria classes: Aeromonas, Vibrio, Pseudomonas, Enterobacteriaceae, Flavobacterium, Acinetobacter, Photobacteriaceae, Brevibacterium, and Micrococcus. In the early stage of storage (1～3 days), Gram-positive bacteria were the major strains and accounted for 70%, most of them belonged to Brevibacterium and Micrococcus.

TBA试验结果显示，添加00.1%以上茶多酚对草鱼脂肪都有明显的抗氧化作用，随浓度增加TBA值增加，但不呈线性关系，0.03%～0.07%抗氧化效果比较接近，从经济、有效的角度考虑在实际应用中可采用0.03%的茶多酚。5、从草鱼中分离出93株菌株，鉴定出以下几类主要腐败细菌：气单胞菌属、弧菌属、假单胞菌属、肠道杆菌科、黄杆菌属、邻单胞菌属、发光杆菌属、产碱杆菌属、短杆菌属、微球菌属、不动杆菌属、无色菌属。
