| Outline of Final Research Achievements |
The anguillid glass eels were collected during two years in estuary of the Cagayan River in northern Luzon Island, the Philippines. Three anguillid species, Anguilla luzonensis, A. bicolor pacifica and A. marmorata were dominant, and A. japonica was rarely occurred. A. celebesensis that was reported in previous studies not occurred in study period. The spawning areas of A. japonica and A. marmorata were overlapping in the North Equatorial Current (NEC), their ages at recruitment were almost same (about 150 days). By contrast, A. bicolor pacifica was recruited about 170 days, which is longer than A. japonica and A. marmorata. A. luzonensis shows intermediate ages at recruitment between A. marmorata and A. bicolor pacifica, suggesting that spawning areas of A. luzonensis locates in NEC.
