Muto et al.: Genetic and morphological differences between Sebastes vulpes and S. zonatus 
437 
Conclusions 
The recognition of S. vulpes and S. zonatus as two dis- 
tinct species is the first step toward establishing a 
biologically based, species-specific management scheme 
for these commercially and recreationally important 
species. In order to demonstrate more detailed evolution- 
ary relationships between the two species, specimens 
sampled throughout their overall distributional range 
are currently under examination. 
Acknowledgments 
We express our sincere gratitude to K. Sakai (Noto 
Marine Center, Ishikawa, Japan) and M. Matada 
(Kanazawa University) for their valuable discussion 
and help in sample collections. Special thanks also 
go to T. Noda (Miyako Station, National Center for 
Stock Enhancement, Fisheries Research Agency), and 
M. Tagawa and K. Nakayama (Kyoto University) for 
helpful comments. G. S. Hardy (Ngunguru, New Zea- 
land) kindly reviewed the manuscript. This study was 
supported in part by a grant-in-aid for scientific research 
(B) from the Japan Society for the Promotion of Science 
(JSPS) (20370034).
