我国浅海滩涂广阔,沿海又有许多河流注入,营养盐类和有机碎屑丰富,适宜鱼虾贝藻类的栖息生长,对开展海水增养殖生产十分有利。据有关部门初步统计,全国浅海滩涂面积近亿亩。其中,可养面积至少有二千万亩。1979年已利用滩涂一百四十余万亩,约占全国已利用的养殖面积的82％;产量约十一万吨,占全国海水养殖产量的四分之一强。假如将可养面积二千万亩的60％利用起来,并改粗养为精养管理,则滩涂养殖面积可达一千二百万亩,产量还是很可观的,足见我国滩涂资源利用的潜力很大。滩涂养殖投资少、见效快、收益大,是一项有重要经挤意义的生产事业。在我国沿海,
China’s vast shallow beach, there are many rivers into the coast, rich in nutrients and organic debris, suitable for habitat and growth of fish and shellfish algae, to carry out the expansion of aquaculture production is very favorable. According to preliminary statistics of relevant departments, the area of shallow beach in China is nearly 100 million mu. Among them, the raised area of at least 20 million mu. In 1979, more than 140,000 mu of beach had been utilized, accounting for about 82% of the area of aquaculture that had been used in the country. The output was about 110,000 tons, accounting for more than one quarter of the national output of mariculture. If 60% of the 200,000 hectares of usable area is to be utilized and renovated for intensive management, the area of beach-type aquaculture will reach 12 million hectares and the output is still considerable. This shows the potential of utilization of the beach resources in China Great. Tidal flat breeding less investment, quick, big gains, is an important business sense of the meaning of the production. In our coastal area,
