This paper analyzed the nutrient content of Andrias davidianus, including protein, fat, calcium and phosphorus; compared the nutrient content of 17 amino acids in protein and the main trace elements in muscle of Andrias davidianus with other high-quality aquatic products (fish, shellfish, shrimp, turtle class, frogs, and snakes); and concluded that Andrias davidianus is a new kind of aquaculture with high nutritional value and significant economic benefits.

张红星1，王启军1，赵虎3，张驰2（1陕西省动物研究所，西安，710032；2 汉中天成生物工程有限公司陕西汉中，723200；3河北农业大学动物科技学院，河北保定 071001）摘要：本文分析了大鲵常规营养成分(蛋白质、脂肪、水分、灰分、钙和磷)的含量，同时对其蛋白质的17种氨基酸和肌肉中的主要微量元素铁、铜、锰、锌进行了与其它优质水产品：鱼类，贝类，虾类，龟、鳖类，蛙、蛇类的营养成分的比较，表明大鲵是一种营养价值极高的经济效益显著的水产养殖新品系。

This thesis used Ultrasonic Assisted Extraction and established pretreatment method for PBDEs and PBBs in both tea leaf and aquicolous propagation, and also optimized Soxhlet Extraction conditions on analysis of PBDEs and PBBs in sediment. This thesis consisted of five chapters.

采用超声辅助提取法作为提取方式，建立了适合于茶叶、鱼类和贝类样品中PBDEs与PBBs同时分析的样品前处理方法；优化了索氏提取法在沉积物样品中PBDEs和PBBs同时分析的条件。

Most of them belong to euryhalin Bacillariophyta,and may be used as the food for shellfish.

Were used; for filter-eeding experiment, the alga used was Nitzschia closterium, and the experimental temperatures were 20, 23, 26, 29℃.Results show that the feeding selectivity of small-ized bay scallop and the oyster increase with algae size:when the algae increased from 4.35m to 11.6m, the feeding rate of bay scallop increased from 4.21%to 11.0%and that of the Pacific oyster from 0.81%to 3.15%.

结果表明，海湾扇贝和太平洋牡蛎的小贝的摄食率随藻类规格的增大而增加；而大贝则表现出明显的差异，海湾扇贝对中等规格（＝5.55—5.79m）的藻类、太平洋牡蛎对小规格（＝4.35m）的藻类具有较高的选择性，表明相同条件下两种贝类对海洋浮游植物群落结构产生不同的影响。

For research of bivalve's effect on marine plankton community structure, we conducted Aug.—Dec. 1996 experiment to study the two bivalves' feeding selectivity and their filter－feeding rates. For observing the feeding selectivity, Chlorella sp., Chaetoceros muelleri, Lermmerman, Nitzschia closterium and Pyramidomonas sp.

于1996年8—12月，分别从青岛海洋大学太平角实验基地和胶南市水产养殖研究所采集海湾扇贝和太平洋牡蛎，采用室内实验的方法，比较研究了不同规格的两种贝类对4种不同大小藻类的选择性及水温对其滤除率的影响。
