为探讨刺参增殖的途径与方法,早在1974年,我所曾在青岛栈桥以西建立人工投石区。1975年秋,放流体长0.5厘米的人工参苗,经过2—3年养成达到商品规格。试验表明,这是一种增加刺参资源的积极而有效的方法之一。从我省自然条件来看,适于刺参栖息的岩礁浅海达10万亩以上,除大量投石放流苗种增殖外,能否直接利用自然岩礁、石块或大叶藻、马尾藻区进行苗种放流增殖工作,是一项值得探讨的重要课题。因此,1981—1983年我们在乳山县进行了这方面的试验。试验区设在县
To explore the ways and means of the proliferation of sea cucumber, as early as 1974, I once built artificial catapult area in the west of Qingdao trestle bridge. In the autumn of 1975, the artificial ginseng seedlings, which had a fluid length of 0.5 cm, were raised to achieve the product specifications after 2-3 years. Experiments show that this is one of the positive and effective ways to increase the resources of sea cucumber. From the perspective of natural conditions in our province, suitable for the habitat of sea cucumber reef shallow Haida more than 10 acres, in addition to a large number of excreted spatter seed multiplication, the direct use of natural rock reefs, rocks or Zoysia, Sargassum zone for seedlings It is an important issue to be explored in this paper. Therefore, we conducted experiments in Rushan from 1981 to 1983. Experimental area located in the county
