Carbon fibers have mostly been applied to structural material of composites and little attention has been paid to other fields. However, it recently became clear that carbon materials act as an activator for microorganism multiplication. In this work, carbon fibers were sunk in seawater to investigate their utilization for a man-made gathering-place for fish and bioremediation. We observed fixation of marine microorganisms on the carbon fiber. Carbon fibers were sunk into the sea and pulled out of the water at a few day intervals. After one day, feeble adhesiveness, that is caused by microorganisms, appeared on the carbon fiber and seemed apt to become a membrane-like feature. After that, algae began to fix on the outside of the carbon fiber tuft, then spread into the inside and increased with the immersion time of the carbon fiber. In that state, small animals such as Maera serratipalma and Photis reinhardi became were discovered in the carbon fiber tuft. Then various organisms began to fix on the carbon fiber tuft. From these experimental observations, it will be indicated that the possibility of a food chain through carbon fiber in the sea arose.
