西太平洋斑海豹主要分布于黄渤海,并达东海北部,其繁殖场在辽东湾40°10′—45′N,121°15′—122°E间的浮冰区,生殖期雌雄成对组成许多“家庭群”,在辽东湾浮冰上产仔,产仔期1—2月中旬,仔兽体被白色绒毛,逃跑时母兽往往背驮仔兽,但2—3月间,在渤海海峡的一些岛屿上也捕获过具有白色胎毛的幼兽。近年来,斑海豹资源已急剧减少,其主要原因为过多的猎捕幼兽,因此必须加强保护。
The Western Pacific Harbor Seal is mainly distributed in the Yellow Sea and the Bohai Sea and reaches the northern part of the East China Sea. Its breeding ground is in the ice-floating area between 40 ° 10’-45’N and 121 ° 15’-122 ° E in Liaodong Bay, Many “family groups” live on ice floes in the Liaodong Bay. During the first 1-2 months of life, the baby bodies are white-fuzzed. When they run away, the maternal beast often piggybacks, but in February-March, Some young animals with white fleece were also captured on some islands of the Strait. In recent years, the harbor seal resources have been drastically reduced, mainly due to the excessive hunting of young cubs and the need to strengthen protection.
