I obtained a Japanese patent on the assumption that the first food for corbicula in Japan would be made by the collective proliferation of microorganisms in the feces of killifish. Details are unknown, but it was expected that a variety of microorganisms would explosively proliferate and produce food in a collective rather than as individuals.
