溞状幼体

中华绒螯蟹溞状幼体期复眼超微结构的观察

Ultrastructure of compound eye in zoaea of Eriocheir sinensis

总糖含量呈下降趋势，由受精卵期占干重的5.65%下降到溞状幼体期的1.9%。

The content of both total carbohydrate and total protein were decreased with embryonic development . The carbohydrate content reduced from 5.65 % of dry weight in the fertilized egg to 1.9 % in the zoea .

结果证实中华绒螯蟹溞状幼体Ⅰ期的PNR在110h左右。

The result showed that the PNR of Zoea - ⅰ was about 110h .

Ⅲ期中华绒螯蟹溞状幼体可捕食桡足类无节幼体，且捕食量随着无节幼体密度增加而变大（P<0.01）；

Third stage zoae ( Z_3 ) could prey on the copepods nauplii , and the feeding amount was increased with the increasing density of the nauplii ( P < 0.01 ) .

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 .

绒螯近方蟹亲蟹、卵、溞状幼体、大眼幼体和幼蟹的感染率分别为82.7%、79.3%、72%、0和42.5%。

The positive rate of natural collect Brood crabs of H. penicillatus , eggs , zoea larva , megalopa larva and junior crab is 82.7 % , 79.3 % , 72 % , 0 and 42.5 % respectively .

碳水化合物在胚胎发育早期逐渐上升，囊胚期含量最高，为胚胎重的13.99%，原肠期下降为8.40%，溞状幼体期的含量为3.05%，孵化出膜后碳水化合物含量继续下降到2.16%。

During the whole embryonic development stage the highest content of the carbohydrate appear in Blastula stage is 13.99 % and the lowest is 3.05 % at the zoea stage . After hatched the content of the protein , total amino acid and the carbohydrate go on decreasing .
