文蛤广泛分布于全国沿海,由于采捕强度过大,自然资源日趋衰落,供需差距越来越大。在这种情况下,从八十年代末以来,一些地区开始进行文蛤人工养殖,使文蛤产量有所回升。但是,由于在养殖技术上还存在着一些问题,文蛤养殖产量不够稳定,经济效益在低水平上波动,养殖面积增加不快。因此,改进和提高养殖技术已成为文蛤大发展的迫切需要。笔者经过总结一些文蛤养殖单位正反两方面的经验教训,对改进和提高文蛤养殖技术提出以下几点建议。 一、重视养殖场地的选择。 选好优良的场地,是文蛤养殖的基础条件,应慎之又慎。要选择地势平坦,风浪较小。潮流畅通的滩涂(或潮沟)。潮位最好是小潮干潮线 Clam widely distributed in the coast of the country, due to excessive harvesting strength, natural resources are declining, the gap between supply and demand is growing. Under such circumstances, since the late 1980s, artificial breeding of clams has been started in some areas and the output of clams has risen somewhat. However, due to some problems in aquaculture technology, the production of clam is not stable enough, the economic benefit fluctuates at a low level, and the area of ​​aquaculture is not increased rapidly. Therefore, improving and raising farming techniques has become an urgent need for the development of clams. After summarizing some positive and negative experiences of both clam aquaculture units, the author made the following suggestions on improving and improving clam farming techniques. First, pay attention to the choice of breeding grounds. Select a good venue, is the basic conditions for clam culture, should be cautious. To choose flat terrain, smaller waves. Flowing tide (or tidal channel). The best tidal level is the tidal wave line
