摘 要:西太平洋灰鲸种群的夏季索饵场主要为鄂霍次克海,该种群每年经鞑靼海峡、朝鲜半岛沿岸南下,进入中国水域。1917—1997年,在中国水域共发现灰鲸31头,其中1933年在东海浙江水域拾1头雌性灰鲸,怀有将分娩的胎儿,1953年春季在广东省徐闻县外罗港渔民捕获两对母仔鲸,据此笔者认为广东沿岸海域为灰鲸的繁殖产仔区。该种群目前已面临绝灭境地,根据近年在其索饵场萨哈林岛附近水域的观察,估计该种群约有130头,在《IUCN受威胁物种名录,2000》中,该种群被列为极危等级,深入开展该种群繁殖区的科学调查研究,对该物种的保护具有重要意义。The feeding cated Strait 1917 in the Okhotsk ground of the western gray whale(Eschrichtius robustus)in sum Sea.
