mysis stage larva-
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 "
眼幼蟲脫第三次即進入糠蝦期幼蟲期mysis stage ，此期之體形已略成蝦之狀態，且具特有之游泳姿態，即頭部及尾部均向下，成一直角彎曲而時作向後跳躍游動，又因成倒立狀態，懸浮於水中的中上層，又叫倒吊期，此期幼蟲對外界的環境因素，如水溫鹽分等變化，比前兩期來得更具適應力，主要餌料為豐年蝦brine shrimp的幼蟲，但其他大小略同的動物性浮游生物，如橈腳類copepoda輪蟲類rotifera均可。The main feed at this time consists of brine shrimp larvae, oyster eggs and diatoms spiruline, skeletonema costatum. however other zooplankton such as copepoda and rotifera can also be used. during the mysis stage the bodies of the fry become larger and so are able to ingest the nauplii of the brine shrimp along with spirulina and

螺旋藻為浮遊性，藻體細長，活的餌料生物能保持水質，營養份很豐富，含高量的蛋白質，天然的維他命，礦物質及類胡蘿卜素，易於自眼幼蟲至糠蝦期攝食。
