随着“以养为主”的水产方针不断落实,全国近海水产养殖业蓬勃发展。不少沿海地区的优良海湾已基本开发利用。因此,目前研究近海湾外沿岸海域的开发已迫在眉睫,意义重大。近几年荣成市在这方面的开发试验已取得较好的效果。现介绍如下。 1 近海湾外区开发的意义和难度 湾外区指脱离海湾岬角包围、水深超过25m等深线的水域。其开发难度主要是筏架难以固定、易被急流和台风袭击、生产投资大,安全性差。 With the continuous implementation of the aquaculture principle of “keeping the environment mainly”, the coastal aquaculture industry in the country has been booming. Many fine coastal areas have been the basic development and utilization. Therefore, it is very urgent and significant to study the development of the coastal area off the coast of the Gulf at present. Rongcheng City in recent years, development and testing in this area has achieved good results. Now introduced as follows. 1 Significance and Difficulty in the Development of Offshore Bay Area The Bay Area refers to waters off the coast of the Bay Head and beyond the depth of 25 m. Its development difficulty is mainly difficult to fix the raft, easily hit by rapids and typhoons, production investment, poor security.
