mysis n.糠蝦屬；〔m-〕糠蝦期,幼體期。

mystagogue
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 糠蝦期幼蟲個體較大，已能攝食豐年蝦無節幼蟲，拌用螺旋藻，蝦苗丹喂飼，其存活率有意想不到的好，將螺旋藻與豐年蝦無節幼蟲，蝦苗丹等配合一起喂飼，其存活率高的原因，在于豐年蝦無節幼蟲亦能攝食螺旋藻蝦苗丹，可增加豐年蝦無節幼蟲的存活率，不僅能節省豐年蝦外，又能避免水質惡化不需要常換水。
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后跳躍游動，又因成倒立狀態，懸浮于水中的中上層，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。
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 螺旋藻為浮游性，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，易于自眼幼蟲至糠蝦期攝食。
During the mysis substages there is a gradual transition from phytoplankton to zooplankton . feed on : diatoms , animalcule such as a . salina , oyster eggs and larvae as well as on rotifers and nematodes 1在糠蝦期幼蟲的蛻變中，漸漸從攝食植物浮游生物轉變到動物浮游生物。餌料：藻類微生物如豐年蝦牡蠣卵輪蟲絲蟲類動物。
2 post - larvae also is the stage when larvae changes their food pattern - from suction to biting . certain kinds of stress occurring during metamorphorsis and stress due to certain larvae not having fully functioning enzyme glands 育苗大量斃死期多在眼幼蟲第二至第三期與糠蝦期mysis至后期幼蟲post larvae之變態期。
For this reason , the water does not need to be changed so frequently . usually in water temperatures of 27 - 29 , with a salinity level of 32 0 00 the three phases of the mysis stage take 3 days to complete 通常在水溫27 29度鹽分32 %之下約3日即可脫下第三次皮而變成后期幼蟲post larvae
In the tank , this cichlid can be fed small feeder fish ( live or frozen ) , mysis shrimp , krill , and worms 水族箱內飼養的六間可以投喂小魚（活魚或者是冰凍），糠蝦，鱗蝦和面包蟲。
Larval shrimp : good for larval shrimp from zoea stages to mysis stage and post - larval stages 投飼量依孵化槽內的幼魚，蝦之密度而增減
