Abstract

A puerulus and five postpueruli of Panulirus japonicus were captured on the Sanriku coast in northeast Japan, from Okkirai Bay in the north to Sendai Bay in the south, in December 1991 and January 1992. Branches of the Kuroshio Current of 20°C or more, approached the Sanriku coast in early October and in early November, 1991. Cultured larvae showed that the duration of the puerulus stage was 15.3 days at 24-25°C. Puerulus swimming duration was estimated to be about seven days. These findings suggest late-stage phyllosomas are transported by the Kuroshio Current towards the coast.
