  1. 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。
  2. It was specially pointed out that, when the tail water is constant maximum tide, the computed flood surface is higher than that of nonsteady current, so there is some safety superelevation. underestimation of the roughness will make downward bias to compute along - river surface and bring hidden trouble for flood control. to improve the section can decrease the water level or offset the water rise for increase of floodplains " roughness, but it need much engineering works

    特別提出，按照恆定流計算出來的設計水位比非恆定水位具有一定的安全儲備；而對于灘地糙率的低估又會造成設計水位的偏低，給防洪工作帶來隱患；如果利用改進斷面形式來降低水位或彌補糙率增加帶來的水位抬高，需要較大的工程量，所以平時應注意灘面的減糙管理工作。
