Can be easily ingest from zoea to post larva stage 可自眼幼虫期开始给饲。
2.
Larval shrimp : good for larval shrimp from zoea stages to mysis stage and post - larval stages 投饲量依孵化槽内的幼鱼，虾之密度而增减

1 . it is very specific for the young larvae to cure digestive system disorders at the stages of zoea 1 .治疗眼幼虫期拖粪期的消化不良特效。
4.
The zoea will begin to catch plankton such as spirulina and skeletonema costatum , oyster eggs or oyster larvae 此时繁殖矽藻，或以水色调节剂，使池水变为淡褐色。
5.
Apply once every two day at night , 2 - 5 ppm each time , from zoea stage continue till transfer of larvae fish to growing pound 两天一次， 2 - 5ppm于夜间实施，从眼幼虫期一直使用到可供放养的虾苗。
6.
At 27 - 29 , the process needs about 50 hours . at 21 - 22 degrees the process needs approximately 110 hours . after molting for the sixth time , the larva enters the zoea stage 无节幼虫虫随著脱皮体形渐大，共有六期，第一期到第六期所需时间依水温高低有所不同，通常在27 29之下约50小时， 21 22之下则约需110小时，于第六次脱皮后即进入眼幼虫期zoea stage 。
7.
Live feed such as the slender spirulina are floating organisms which can maintain good water quality and are also abundant in nutrients , proteins , natural vitamins , minerals and carotenoid . they are suitable food for the shrimp larvae from the zoea through to the mysis stage of development 螺旋藻为浮游性，藻体细长，活的饵料生物能保持水质，营养份很丰富，含高量的蛋白质，天然的维他命，矿物质及类胡萝卜素，易于自眼幼虫至糠虾期摄食。
8.
After molting three times , the zoea enter the mysis stage during which they begin to look more like adult shrimp and swim in a characteristic fashion with head and tail pointed downwards at right angles and occasionally performing a sudden retrograde jumping action . this is known as the inversion state , the fry being suspended upside - down in the upper middle region of the pond water . this is , therefore , also called the " inverted suspension phase " 眼幼虫脱第三次即进入糠虾期幼虫期mysis stage ，此期之体形已略成虾之状态，且具特有之游泳姿态，即头部及尾部均向下，成一直角弯曲而时作向后跳跃游动，又因成倒立状态，悬浮于水中的中上层，又叫倒吊期，此期幼虫对外界的环境因素，如水温盐分等变化，比前两期来得更具适应力，主要饵料为丰年虾brine shrimp的幼虫，但其他大小略同的动物性浮游生物，如桡脚类copepoda轮虫类rotifera均可。
9.
In these transition periods , the digestion system is not well developed yet and is very sensitive to any change in their digestion systems . this stress - related indigestion can eventually lead to death . the stress is easily induced in the above mentioned two stages because zoea begins to take external food since the yolk in its body has been consumed during the nauplius stage ，是由多种酵素，黄莲黄柏抽出物的综合体，能迅速安全的分解残饵，解决污泥产生，免除亚硝酸及阿摩尼亚所造成的生理紧迫，更因为神奇的酵素作用，能帮助虾苗肠道的正常机能，避免虾苗初饲食物或改变饲料的生理紧迫消化不良而导致死亡。
