摘要
由于近年来滥捕现象严重,同时受沿岸水域污染的影响,刺参资源量明显减少,年产量急剧下降。因此迅速恢复和增加刺参资源,提高生产量已受到有关部门和人员的高度重视。传统自然海区人工增殖研究以投石筑礁为主要措施。如日本早在三十年代已普及推广投石、投废旧汽车轮胎、沉废旧船等筑礁措施,并结合投放树枝捆和移植亲参等方法。
The explosion in seabed neither harm the sea creatures nor pollute the water in the test area. The shape of the seabed exploded was liable to form whirling current and advantageous to the deposition of the organic detritus, to expand the summering place for the sea cucumbers, to improve their living circumstance and to promote their increase in quantity. Generally the amount of the sea cucumber per unit area tested was 3—7 times than the area before test.
There was a very good result of breeding by putting the artificial hatched and cultured young animals into the seabed exploded and constructed. It can be considered as a highly effective way of enhancement.
The explosion and construction of rock reefs in seabed could be operated easily with low cost.
