Abstract
|
|
|
|
The complete larval development of Enocheir japonicus De Haan reared in the laboratory is described and illustrated. E. japonicus passes through 5 zoeal stages before metamorphosis to the megalopal stage. The megalopa and crab I inStar are attained in 17 and 27 days after hatching, respectively. The culture was carried out under a photoperiod of 14 h light and 10 h dark and a constant temperature of 25℃. Morphological charaderistics of each larval stage of this species are compared with those of E. japonicus from Japan. Morphological features between zoea I of the Varuninae are briefly discussed.
