TCRI Washington D.C. Office we had opened in the capital of the United States in August 2001was closed in July 28 2004.

US crayfishes known in Japan are only Red Swamp Crayfish, Blue Florida Crayfish and P/trawbridgii. But the United States encompasses about 350 species of crayfishes, 70 % of the world total.

In this treasure-house of crayfish we enjoyed studying a lot and we express our gratitude to those who had supported our activities.
