摘要:
附着生物对航运、港工建筑、发电厂、水产养殖等危害性极大,因而很早便引起人们的普遍重视.我们在调查研究我国沿岸的附着生物中,把洞头岛列为调查点.并于1978年6月-1979年5月进行周年挂板试验.洞头岛位于浙江东南部瓯江口外.试点设在岛西北面新码头外特设的浮筏,水流畅通,低潮水深5米左右,透明度低,水温年变化在7.8-28℃,最低二月份,最高8月份,年平均水温18℃,终年盐度均在27‰以上,最高达到34‰.试验方法基本上按海洋调查规范进行,挂板分表、底两层,表层只挂木板,用尼龙丝系在水面以搜集藻类,底层试板固定在铁框架里,铁框用铁链垂直悬挂在水下2-3米深处.
Abstract:
Studies on Marine biofouing were conducted in Dongtou waters, during the period from June 1978 to May 1979.61 species of fouling organisms were collected on 81 test panels.The major species of the fouling organisms are Bdldnus uliginosus, B. eiudtus, B.reticuldtus, Ostred sp.,Anthopleurd pdeificd, Eudendrium sp,Tubuldrid mesembrydnthemum, Acdnthodesia bifloris Membranipora amoyensis, Enteromorpha intestnalis and Ulva linza.
