摘要


多齒新米蝦(Neocaridina denticulalta De Haan)是匙指蝦科(Atyidae)中的一種,廣佈於臺灣各地的淡水域中。本研究得知在水温23~26℃的條件下,其卵在產下後第30天孵出底棲性的幼苗,而幼苗則在18~22℃的條件下於第19天發育至第五期。本報告中除了記錄孵化過程中卵徑及卵色的變化外,亦對五期幼苗之形態特徵加以描繪敘述,同時亦和日本九州及琉球產的幼苗進行發育日期、大小及額齒之比較。

Neocaridina denticulata (De Haan, 1884) is a very common freshwatre Caridean shrimp in Taiwan. Under laboratory conditions of 23-26°C. the larvae hatched out in the 30th day. The larvae experienced five molts and closely resembled with the adults in 19 days after hatching at water temperature of 18-22 °C. The color and size of the eggs, as well as the morphological characteristics of the different larval stages were described and illustrated. The results of the present study were compared with those reported for the same specie s collected in Japan.
