结果表明，1.虾苗酶活力结果为：类胰蛋白酶及胃蛋白酶的活性有差异，溞状幼体期<糠虾幼体期<仔虾期；

The results indicate that : 1 . The activities of trypsin-like enzyme and pepsin were different in different stage of the larvae of prawn : Penaeus chinensis Zoea stage < Mysis stage < Post larval stage .

状、糠虾、仔虾48h的LC50值分别为11.19、11.41和37.34mg／dm3NO-2-N；

1994年，5.5%的糠虾幼体和5.1%的仔虾检出有HPV的感染。在糠虾和仔虾阶段，海捕亲虾苗种的HPV带毒率为4.0%，越冬亲虾苗种的带毒率为6.2%。

In 1994 , 5 . 5 % mysis and 5.1 % postlarvae were infected by HPV . During mysis and postlarval stage , the viruliferous rate of HPV in larvae from wild spawners was 4.0 % , while that from overwintering spawners was 6.2 % .

哲水蚤、蟹类幼体和仔稚鱼主要出现在5月，短额刺糠虾主要出现在10月。

Calanoida , zoea larvae of crabs and fish larva mainly occurred in May .

在以前的分类中是软甲亚纲的一个部；现在被糠虾目和鳞虾目取代。

In former classifications a division of Malacostraca ; superseded by the orders Mysidacea and Euphausiacea .

与糠虾法和发光细菌法相比，发光海藻法具有抗干扰能力强、灵敏度高、检测时间短等优点。

This method has the advantage of good anti-jamming ability , higher sensitivity and short test time .

目前将糠虾作为环境监测的一种很好的模式动物，已被国内外广泛接受。

Now mysis shrimp as a good model animals in environment monitoring has been widely accepted domestic and overseas .

在糠虾幼虫第一期，胃分为贲门胃和幽门胃两部分。

Stomach is composed of two parts , the cardiac and pyloric region , at the first stage of mysis .

These results demonstrate that histamine has the effect on the embryogenesis , and affect significantly with the extension of immersion time . 2 .

1993年和1994年育苗期，在山东省十余家育苗场采集了亲虾、受精卵、无节幼体、蚤状幼体、糠虾幼体和仔虾等样品共56份。

Samples including spawners , fertilized eggs , nauplius , zoea , mysis and postlarval were taken from more than ten hatcheries during larval rearing period in 1993-1994 in Shandong province .

糠虾期、仔虾期在低盐度（S18.66）中生长速度快于在高盐度中，且在逐级递降的淡化过程中，仔虾的成活率较高。

Growth rate in mysis and larvae shrimp stage is greater at lower salinity ( S 18.66 ) than in higher salinity . And the survival rate of larvae shrimp is greater during the gradually desalting period .

对虾选择河口附近海区产卵，但卵子一定要在盐度较高的海水中孵化变态，所见淹状、糠虾幼体分布的最低盐度为17.90‰；

Spawning of penaeid shrimp took place in the vicinity of estuaries , but only when the salinity of the sea water became higher could the eggs hatch and metamorphosis . The lowest salinity at which zoea and mysis have been found was 17.9 ‰ .
