Here in Auburn, in Washington state ( as with most West coast cities) we had an influx of farmers from japan in the thirties.
In a verbal history from my friend who ran a japanese grocery store, he and his Dad came over from Japan in the late 30's by boat, and they brought with them several metal milk containers full of 2-3 inch fry.They dd water changes daily from their rationed water. Only a handful made the long perilous journey to reside in a pond on their property until the dad passed.
I always loved visiting his store and getting him to tell me the history of the valley which was then one big farming operation. Now it's all paved over with warehouses and trac housing.
I was priviledged to be among the first members of Puget Sound Koi Club, the first and oldest AKCA club in our state. I was also happy to be a founding Father of Washington Koi and watergarden and it's first president who installed our first show which is now a fixture.
