为了探讨文蛤苗种生产技术和文蛤资源增殖技术,1998年至2001年,我们在山东省滨州市旺子岛滩涂进行了半人工采苗增殖技术试验,取得了较好的经济、生态、社会效益,现将试验情况总结如下: 一、材料与方法 1、试验区的条件 试验区选择在滨州市旺子岛滩涂高潮区下部和中潮区之间,滩面平坦而稳定,附近有大量产卵群体,饲料生物量丰富,水质未受到污染。潮流畅通平缓,含沙量在70％以上
In order to explore the production technology of clam seed and the propagation technology of clam resources, we conducted the semi-artificial seedling multiplication experiment in Wangzi Island beach of Binzhou City, Shandong Province from 1998 to 2001, and achieved good economic, ecological and social benefits , The test conditions are summarized as follows: I. Materials and methods 1. The experimental area The test area is selected between the lower part of the high tide zone and the mid-tidal area of the Wangzi Island beach in Binzhou. The beach surface is flat and stable with a large number of spawning groups nearby , Feed rich in biomass, water quality has not been polluted. Tide smooth, sandy sediment in more than 70%
