Abstract
Grazing pressure for kelp forest formation was conducted from 1997 to 1999. Experimental fields established in two 'Isoyake areas', Otaru and Tomari. To control the grazing pressure, two fields were encIosed by fence, and the sea urchin, Strongylocentrotsu, was removed in the fence. The fence prevents the invasion of sea urchin from outside of fence to inside. At the experimental fields,sSea urchins were no grazing over the winter, whereas the urchins add grazing during summer. Vegetation was observed in both of inside and outside of the fence. Kelp forest appeared only inside of fence, but Isoyake continued in outside of fence. Gonad of sea urchin at the new kelp forest increased in qualitative and quantitative.
