This may be due to hydrolytic chelating, precipitation and the sediment or hydrobioes attachment, absorption etc. The honewort had stronger ability of accumulating La because of its large leaf surface that could attach La. The accumulating ability of snail and fish to La was relatively weaker but some organs of them had higher contents of La especially in the intestines, shell of snail, and in gill, internal organs, scales, head, bone of fish, rare in muscle. The total accumulating quantities of La in each component of simulated aquatic ecosystem were a decreasing order of: sediment ＞honewort＞snail＞fish, and the sequence of bio-concentration facter was as follows: honewort＞snail＞fish.

2金鱼藻对La有较强的富集能力，主要通过枝叶表面吸附、吸收而富集；螺蛳对La也有一定的富集，并主要分布于肠、壳中，螺头中积累相对较少；草鱼对La的富集能力相对较弱，进入鱼体的La主要集中在鳃、内脏、鳞及头、骨中，肌肉中积累量较少；按质量计，稀土元素La在模拟水生态系统各部分中的积累量依次为：底泥＞金鱼藻＞螺蛳＞草鱼；各水生生物对稀土La的生物富集因子依次为：金鱼藻＞螺蛳＞草鱼。

The results showed that the American shad fingerlings stopped opercular movement less than half an hour after anesthetia when the fish were exposed to concentration of MS-222 at 75mg/L, clove oil at 20mg/L and bezocaine at 40mg/L. The fish recovered to normal behaviors again after exposed in air for less than 10min when transferred into fresh water. The shad fingerlings had good anaesthesia for more than 12h at 20-30mg MS-222/L, 8-10mg/L clove oil and 20-30mg/L benzocaine. The anesthetic effects were enhanced at high water temperature and changed with fish sizes. Small fish were more easily in good anaesthesia than the bigger one in MS-222 while the opposite case was found in clove oil and in benzocaine.

麻醉试验结果表明：在较高麻醉浓度（MS-222为75mg/L以上，丁香油为20mg/L以上，苯唑卡因为40mg/L以上）下，鱼很快（30min内）停止鳃盖张合运动，且停止鳃盖运动的鱼在空气中暴露一定时间（10min内）后也能够复苏；在适宜的麻醉浓度（Ms-222为20~30mg/L，丁香油为8~10mg/L；苯唑卡因为20~30mg/L）下，鱼能够进入麻醉状态，且能保持很长时间(12h)；麻醉效果随着水温的升高而增强；在20mg/L MS-222麻醉剂下，小规格鱼较大规格鱼更容易进入麻醉状态，而在10mg/L丁香油和20mg/L苯唑卡因麻醉剂下，小规格鱼却难进入麻醉状态。

The above indexes of fish fed 4% and 12% M. sativa meal were higher than those of fish fed 16% M. sativa meal and were lower for fish fed fresh M. sativa than that of the control group. 2 With increased levels of M. sativa meal in the diets, crude protein content in the muscle of fish fed M. sativa meal increased significantly, while EE and cholesterol were significantly decreased and moisture showed a quadric curve variation. Fish fed fresh M. sativa had no improvement in comparison to the control group. 3 Protease and amylase in foregut, midgut, hindgut and hepatopancreas of C. carpio increased with increased M. sativa meal but the variation was not linear.
