The aim of this study was to produce a new type of artificial reef to grow seaweeds and provide habitat for Japanese spiny lobsters, abalone and other important fishery resources.
Site Selection Criteria:
Sites with three types of bottom substrata (sandy, boulder and rocks) at 5-10m were selected.
Cause Of Decline:
Grazing by sea urchins has led to the widespread loss of kelp ('isoyake') in Japan. In this process macroalgae species such as Sargasseous and Laminariaceous species are replaced by coralline species, and consequently, fishery resources such as abalone, lobster and fish became extremely depleted.
