一、文蛤的增养殖技术目前文蛤的增养殖方法大体有以下几种: (一)加强管理,保护增殖资源建立文蛤自然保护区,实行定期封滩养殖,促进文蛤自然增殖。封滩养殖的主要做法是:在文蛤繁殖季节,严格执行禁捕期和禁捕规格,以保护亲贝繁殖衍生。划定苗区和养殖区,加强管理,即根据贝苗栖息在偏高潮位的特点,将高潮区下部和中潮区上部划定为苗区,实行封滩护养,严禁人畜踩踏破坏;又依据文蛤生长及其活动规律,将中潮区下部和低潮区划定为养殖区,并采取轮捕轮放、捕大留小等措施。近年来,江苏省如东县由于采取了严格有效的保护措施,新港滩涂的幼贝密集,每平方米达到8,000个,即使在贫瘠的环港滩涂上,每平方米也有1,000个以上。1983年江苏省水产部门对封滩养殖区进行检测,文蛤资源增殖率较未封滩保护的海区提高2.4倍。
First, the culture of clam increased culture Currently clams increased culture methods generally have the following: (A) to strengthen management and conservation of resources to establish the conservation of clam nature reserve, the implementation of regular seal beach farming to promote the natural proliferation of clams. The main practice of sea fostering is: During the breeding season of clams, strictly enforce the Prohibition and Prohibition Regulations to protect the progeny from reproduction. According to the characteristics of Baimiao habitat at the high tide level, the lower part of the climax area and the upper part of the mid-tidal area are designated as the saplings area, Growth and the law of its activities, the lower part of the tide area and the low tide area shall be designated as the aquaculture area, and take the wheel catching and wheeling and catching the big and small measures. In recent years, due to strict and effective protection measures in Rudong County, Jiangsu Province, the density of baby bass in Xingang Beach has reached 8,000 per square meter. There are more than 1,000 per square meter even in the impoverished harbor beach. In 1983, the department of aquatic products in Jiangsu Province conducted a test on the sealed beach aquaculture area, and the proliferation rate of clam resources was 2.4 times higher than that of the sea area that was not protected by the sealed beach.
