Creation of the Japanese Common Sea Cucumber Fishing Ground Using Japanese Scallop Shell Fragments

Abstract

In this study, we developed a method of the Japanese common sea cucumber fishing ground using the Japanese scallop shell fragments. To evaluate the significance of sea cucumber production and the influence on environment, we investigated adult sea cucumber aggregation and juvenile sea cucumber bottom clinging, water and sediment qualities after laying the shell fragment on the fishing ground. The results indicated that the shell fragments laying had significant effect to the sea cucumber aggretion and bottom clinging with little influence on water and sediment qualities.
