山东省烟台市蓬莱、长岛养殖场扇贝笼网上污损生物特点及其防涂的研究

THE CHARACTERISTICS AND CONTROL OF FOULING ORGANJSMS ON THE LANTERN NETS FOR CULTIVATING SCALLOPS (PEETEN MAXIMUS) IN PENGLAI AND CHAHGDAO CULTIVATING FARMS

在扇贝养殖期内(5月下旬到10月下旬),附着在灯笼网上的污损生物,在蓬莱水域发现有5种动物和8种藻类;在长岛水域发现有5种动物和6种藻类,两水域危害严重的优势种类及其附着季节有明显不同。采用“JS-867防污剂—③号”浸涂扇贝灯笼网同未涂该防污剂的扇贝灯笼网对照组相比较,有明显的防污效果。“JS-867防污剂”是值得推广,行之有效的防污涂料。

To prevent and kill fouling organisms adhering to the lantern nets during the cultivating puiod (from the first ten days of May to this of October) of Scallops cultivation, a series of experiments were conducted in the mariculture station in Yantai from 1985～1987. The findings reveal the adhering organisms comprise 7 species of invertebrates and 8 species of algae. The adhering season happened from June to septemer. Knowing the characteristics of the organisms, We developed a paint complex with ionic copper and tin ingredients, which was proved effective in good prevention and killing of these organisms. Accumulation of copper and tininons in scallops is below the quantites allowed of in the Chinese standards for Food and Health. Moreover the ions released from the paint only slightly polluted the water for mariculture.
