| Abstract | The leptocephalus larvae of Conger myriaster (Brevoort) appear commonly in the coastal waters from Kagoshima Prefecture to Hakodate, Hokkaido, between November to July.1-3) The larvae are one of the main constituents of ichthyoplankton in the coastal waters around Japan. All larvae so far collected, however, were more than 84mm in body length and belonged to the latest developing stage of leptocephalus or the metamorphic stage. The spawning ground, spawning season, and ecology of the leptocephali in the ocean remain unknown at present. Recently, the daily growth rings on the otolith have been observed in many species of larval fishes, and ageing by counting the daily growth rings has been shown to be useful for the ecological studies of the larvae.4-9) The otoliths of leptocephalus larvae of the conger eel have rings similar to the daily growth rings observed in other fish larvae. The authors observed the microstructure of the otoliths of the conger eel larvae using a scanning electron microscope with reference to the ecology in the Seto Inland Sea. Materials and Method |
