【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。更多还原

【Abstract】 The feeding ground of the western gray whale(Eschrichtius robustus)in summer was mainly located in the Okhotsk Sea.The gray whales usually migrate into the waters of China crossing Tatarskiy Strait and along the Korean peninsula.Thirty-one gray whales were recorded in the waters of China from 1917 to 1997.A female gray whale with a fetus was found in the coastal water of Zhejiang province in 1933.In the spring of 1953,the fishermen of Wailuo port captured two pairs of female and pup gray whales.Therefore,the coastal water area off Guangdong province was regarded as a breeding ground for the western gray whale population.Currently,the western gray whale population was facing a danger of extinction,estimated to total around 130 individuals by the survey in feeding ground-the water off Sakhalin Island and has been as "Critically Endangered" by the World Conservation Union(IUCN)in 2000.So it was of great significance to conduct investigation and research on the breeding ground of the population for the protection of the species.更多还原
