The lizardfishes Saurida spp. are commercially important to the Japanese trawl-fisheries, and are utilized as surimi or fish cakes 'kamaboko' in Japan due to its high meat yield, and high gel forming ability. In recent years, stock levels of lizardfish have been low in the East China Sea similar to other demersal fishes. The Japanese large pair trawl fishery catch per unit effort of lizardfish in the East China Sea in 2006 was 9% of that in 1982, and the landing of lizardfish from Japanese large trawl in the East China Sea decreased from 8585 metric tons in 1982 to 23 metric tons in 2006. Similarly, in the Tsushima/Korea Strait the landing of lizardfish from the Japanese offshore trawl also decreased by about 30% between 1973 and 2006. Lizardfishes are commercially important to the Japanese trawl fisheries, assessment of lizardfish stocks and establishment of fishery management guidelines are urgently needed. The purpose of the present study is to update information on the biological characteristics, for formulating management proposals on the fishery in the East China Sea and Tsushima/Korea Strait.
