中文摘要:
      本文报道了对紫石房蛤生物学调查研究的初步结果。 紫石房蛤是狭盐、冷水性贝类,栖息于4—20 米水深,潮流畅通,水质清澈的沙砾底质海区;适应的水温是2—28℃,盐度是20—34‰,营埋栖生活。其食物以硅藻为主。Ⅴ龄以前的个体生长迅速。体重和体长的关系为:W=0.000014 L3.89-18。 紫石房蛤为雌雄异体,繁殖期在6月至9月上旬。据测定,其生殖腺指数在7月初达到最高值,为19.8%。此外,本文还对紫石房蛤的胚胎发育过程作了描述。
英文摘要:
      The Distributions of Saxidomus purpurarurs (Sowerby) have been reported from the provinces of Shandong, Liaoning in China and Kyushu, Shikoku, Honsuh, etc. inJapan. It is distributed mainly along the coast of North Pacific (30-40°N.). It is alarge type of economic bivalve with delicious taste. Peoples of many countries like it.Its largest body weight reaches to 0.5 kilogram. It is ecology and breeding habit has been studied in recent years. This article describes its living environment, food habit and growth. Saxidomusperpuratus (Sowerby) lives at a depth of 4-20 meters, with water temperature2-28℃ and salinity 20-30‰. It mainly feeds on diatomes. The Spawning season is in June to September. Its embryonic development is alsodescribed in this article.
