| 摘要: |
| 菲律宾蛤仔 Ruditapes philippinarum (又称蛤仔)在我国沿海均有分布,以辽东半岛和山东半岛的密度为最高。近年来由于水产品需求量日益增长及渔业资源严重衰退,蛤仔已成为我国渔业捕捞和养殖的重要经济贝类之一。80年代以来,随着蛤仔资源的开发利用,国内开始重视对蛤仔的生态调查和研究。本文根据作者1989-1990年对胶州湾水域非律宾蛤仔的生态和资源量的系统调査资料,以及国内的有关报道(刘永峰等,1979;庄启谦等,1981;林笔水等,1983;齐秋贞,1987;李明云等,1987;吴耀泉等,1992),对分布在我国的蛤仔生态特征进行了综合分析,为保护蛤仔资源、合理捕捞和发展蛤仔增养殖提供了必要的科学依据。 |

| Abstract: |
| Ruditapes philippinarum distributed in the coast of the Bohai Sea, Yellow Sea, East China Sea. and South China Sea lives in the inter-tidal zone of shallow water about 10m in depth where salinity is usually 30.8-32.0, and temperature, 2℃-27℃. It is most densely distributed in the Liaoning and Shandong coasts where it is usually found living in silty-sand(?0.004-0.063mm) bottom. It reproduces in spring and autumn in the Bohai Sea and Yellow Sea, but in the East China Sea and South China Sea, only in autumn. The< 1 year age group is composed mostly of individuals having shell length of 3.5-7.5mm, and the 4-year age group, ahell length of 17.4-21.6mm,24.5-33.7mm,33-43.8mm,and36-49.6mm. |
