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.
