毛主席教导我们:“不搞科学技术,生产无法提高。”在毛主席革命路线的指引下,我国海产贝类人工育苗如雨后春笋,蓬勃发展。育苗品种有所增加,不少社队水产养殖场依靠群众,自力更生,艰苦奋斗,开展了人工育苗工作,全国育苗单位多达几十个。在去年全国海水养殖经验交流会议的推动下,贝类人工育苗获得较快发展。有些品种的人工育苗已用于生产。山东省贻贝人工育苗一立方水体出苗率达一百多万粒,最高达三百来万。利用藻类育苗室进行贝类人工育苗和土池育苗的经验,取得初步成效。广东的华贵栉孔扇贝,福建的杂色蛤仔、山东的青蛤,都获得了成功。鲍鱼、珍珠贝、泥蚶、牡蛎、缢蛏、栉孔扇贝、翡翠贻贝等人工催产、受精、孵化和培育率都有所提高。
Chairman Mao taught us: “Without scientific and technological means, production can not be improved.” Under the guidance of Chairman Mao’s revolutionary line, the artificial seedling raising of marine shellfish in our country has mushroomed and flourished. Breeding varieties have increased, many community aquaculture farms rely on the masses, self-reliance and arduous struggle, carried out artificial breeding work, the country’s nursery units up to dozens. Under the impetus of the national conference on seawater aquaculture exchange last year, artificial breeding of shellfish has achieved rapid development. Some varieties of artificial breeding have been used for production. Shandong mussel artificial seedling a cubic water body emergence rate of more than one million, up to 30000000. The use of algae nursery room for artificial breeding of shellfish and soil pond nursery experience and achieved initial results. Guangdong’s luxury Zhikong scallops, Fujian’s variegatus clam, Shandong clam, have been successful. Abalone, pearl oyster, mud cake, oysters, catfish, scallop, jade mussels and other artificial labor, fertilization, hatching and breeding rates have increased.
