Research Abstract

To understand mechanisms of stock fluctuation of the anguillid eels, the downstream and the oceanic larval migration of ancestral tropical species(Anguilla celebesensis and A. marmorata) have been studied. This led the discovery of a new species(A luzonensis) from the Philippines, and many important information on the downstream migration and spawning ecology of the tropical anguillids.
