摘要:

至今,中国海已经记录了66种海鞘。其中,渤海有5种,黄海21种,东海24种,南海53种。种类分布从北往南逐渐递增,柄瘤海鞘在黄海、渤海数量很大(8100个/m2),但往南分布,未发现超过罗源湾。皱瘤海鞘在南海数量很大(2225个/m2),往北也未发现超过罗源湾。玻璃海鞘和乳突皮海鞘在全国沿海都有分布。

Abstract

So far,66 species of ascidian have been recorded in China seas. Where 5 species are found in the Bohai Sea,21 in the Yellow Sea, 24 in the East China Sea and 53 in the South China Sea. The number of species increases from the North to the South. In the Yellow Sea and Bohai Sea, Styela clava has great amount in density reaching 8100 Ind./m2 and it never distributes beyond Luoyuan Bay to the South. Styela plicata has great amount in the South China Sea, and greatest density reaching 2225 Ind./m2, it never distributes beyond Luoyuan Bay to the North. Ciona intestinalis and Molgula manhattensis distribute in all the seas along the coast.
