日本每年对海带的进口量为2000t,但由于1990年中国和南朝鲜的海带产量下降,而导致了进口量的锐减。可是1991年的海带进口量将接近进口计划。最近,由北海道渔联、日本海带协会、全国烹调协会三者组成的海带进口协议会,访问了中国的海带产地烟台、威海、大连, Japan imports 2000 kelvin annually, but imports dropped sharply as kelp production declined in China and South Korea in 1990. However, imports of kelp in 1991 will be close to the import plan. Recently, the kelp import agreement meeting consisting of the Hokkaido Federation of Fisheries, the Japan Seaweed Association and the National Cuisine Association visited the kelp areas of China, namely Yantai, Weihai and Dalian.
