从大鲵的尾部开始,每隔1 cm切取大鲵肉块,观察其脂肪组织分布;通过石蜡切片、HE染色后观察脂肪细胞;通过流变仪测定大鲵脂肪粘度;通过气相色谱/质谱联用技术分析大鲵脂肪的脂肪酸组成.结果表明,大鲵脂肪主要集中于尾部2/3处至尾尖,尾部2/3处至尾鳍部脂肪含量显著减少,尾鳍部只存在极少量的皮下脂肪;脂肪细胞有较强的流动性,易变形、易碎;脂肪具牛顿流体特性,粘度为0.0289Paos;大鲵脂肪主要含13种脂肪酸(C_(18:1)24.2%,C_(16:0)15.4%,C_(16:1)13.7%,C_(18:2)8.2%,C_(20:5)6.7%,C_(18:3)4.5%,C_(22:6)4.3%,C_(14:1)3.0%,C_(18:0)2.8%,C_(22:5)2.6%,C_(20:4)2.2%,C_(17:0)2.0%,C_(17:1)1.9%).

Andrias davidianus flesh was cut every other 1 cm from the tail end;and adipose tissue distribution was explored;and fat cells were observed via paraffin-dyed section;and fat viscosity was measured by rheometer;and fatty acids were analysed with GC6890N/MSD5973N.The results showed the Andrias davidianus fat mainly concentrate on two thirds of the tail to tail top;and the fat content is markedly decrease from two thirds of the tail to tail fin;and there is little subcutaneous fat on the tail fin; and the fat cells have a strong mobility, easy deformed and broken;and Andrias davidianus fat is Newtonian fluid;and the viscosity is 0.0289Paos;and Andrias davidianus fat mainly contain 13 kinds fatty acids(C_(18:1)24.2%,C_(16:0)15.4%,C_(16:1)13.7%,C_(18:2)8.2%,C_(20:5)6.7%,C_(18:3)4.5%,C_(22:6)4.3%,C_(14:1)3.0%, C_(18:0)2.8%,C_(22:5)2.6%,C_(20:4)2.2%,C_(17:0)2.0% and C_(17:1)1.9%).
