摘　　要：测定了团头鲂Ｍｅｇａｌｏｂｒａｍａａｍｂｌｙｃｅｐｈａｌａ夏花、一龄、二龄鱼种和成鱼的２０种化学元素，其在鱼体干物质中的总含量为５．２５％～８．０４％。其中约４０％分布在肌肉中，６０％分布在骨骼中。含量高的为Ｃａ、Ｐ，占２０种元素总量的７０．２９％～７８．６１％。Ｃａ：Ｐ为１：０．４７～１：Ｏ．７１。含量低于Ｃａ、Ｐ的依次为Ｋ、Ｎａ、Ｓ、Ｍｇ、Ａｌ等。随着鱼体长大，大多数化学元素相对含量减少，只有Ｋ、Ｓ、Ｐｂ的含量随之增加。The content of 20 mineral elements in summer fry, one-year Juvenile. two-year juvenile and adultfish of Megalobrama amblycephala were determined to be 5. 25%-8. 04 % of dry weight of the fish body. Forty Percentsof the minerals was contained in muscles, and 60% was in skeletons. Calcium and phosphorus were two principle elements, occupying 70. 29 %-78. 61 % of total elements. The ratio of Ca to P was 1: 0. 47' 1: 0. 71. Other elementsin decreasing order were K, Na, S, Mg, Al, etc. The contents and Percentages of different elements varied with fishgrowth. The relative contents of most elements decreased with the growth of fish, while those of Potassium. sulfurand lead increased.
