1983年我们分别对同一批人工繁殖获得的2龄三角帆蚌,在同一池塘中进行网袋挂养和穿孔吊养的对比试验,两种方式饲养的深度和管理情况均一致。网袋挂养采用9号网片制成单层5个袋一排的网袋,每个袋放1只蚌,蚌的腹缘向上,隔一段时间变动一下蚌的体位,但腹缘始终向上放置。吊养即是在蚌的翼部钻一小孔,用尼龙绳穿起,蚌的腹缘向下,挂养池中。
In 1983, we conducted the comparative experiments on the same batch of artificial propagation of Hyriopsis cumingii, which were carried by net bags in the same pond and perforation, respectively. The depth and management of the two methods were the same. Mesh bags linked to the use of No. 9 net made of single-layer network of 5 bags in a row of net bags, each bag put a clam, mussels on the edge of the belly up, after a period of time to change clam posture, but the belly edge always up place. Hanging is to drill a hole in the clam wing, with nylon rope to wear, clam down the belly edge, hanging pool.
