| 摘要: |
| 菲律宾蛤仔Ruditapes philippinarum(又称蛤仔)是青岛胶州湾的一种主要经济贝类。从潮间带到水深10m左右的水域均有蛤仔栖息。蛤仔具有繁殖力强,生长快,肉质鲜嫩等特点,是青岛市出口创汇的重要水产品种。近年来,由于国内、外市场对蛤仔的需求量日益增加,促使渔民盲目扩大捕捞强度,从而导致蛤仔资源衰退。为此,作者曾于1989-1990年进行了胶州湾蛤仔的生态和资源量系统调査硏究(吴耀泉等,1992)。而后,为了更有效地保护和持续利用蛤仔资源,于1991-1995年继续深入研究了幼蛤(简称蛤苗)的数量动态与其资源补充量的关系,为建立胶州湾蛤仔资源补充量的预报及实施计划捕捞生产提供了必要的决策依据。 |

| Abstract: |
| Results of a April, 1991-1995 in Jiaozhou Bay survey on the reproduction of clam Ruditapes philippinarum juveniles show that they can be approximately divided into the spring batch and the autumn batch. The spring batch of juvenile clams comprising about 40%of the population, attained shell length of 8-16mm while the autumn batch of juvenile clams, comprising about 60%and constituting the main replenished population, reached a shell length of 2. 5-7mm. A declining trend of replenished population was observed. |
