室內培育之東方白蝦幼苗變態研究
Morphological Observation on the Larval Development of Exopalaemon orientis (Holthuis, 1950HCrustacea, Decapoda, Palaemonidae) Reared in the Laboratory
摘要
東方白蝦Exopalaemon orientis(Holthuis, 1950)是一種棲息於臺灣沿岸沙底或沙泥底的一種小型蝦類，亦經常出現於養殖池中，其幼苗在室內水溫26-28℃，鹽度21-22ppt的條件下以豐年蝦之無節幼體飼育;自卵孵化後，經過6期蚤狀幼體變態，在第10天出現後期蝦苗，並在第12天全部變態完成，本報告除對各期幼苗均有詳細之描述外，並與產於日本Shin hama海水湖之東方白蝦幼苗進行比較。

Exopalaemon orientis (Holthuis, 1950)is a small Palaemonid shrimp, and distributed in Indo-West Pacific, Japan, Korea, China, and Taiwan. They usually inhabit the sand and mud shore with sea-water or brakish-water, and are also found in culture pond. The development pattern of larva belongs to ＂Common type＂. From newly hatch out to post-larva, it goes through 6 zoeal stages under the laboratory condition of water temperature 26-28℃, salinity 21-22ppt and fed with Artemia nauplii. It required about 10-12 days to reach postlarval stage. The morphological characteristics of each stage are described and illustrated, and compared with E. orientis from Shin-Hama in Japan.
