【摘要】 <正> 角蝾螺(Turbo cornutus Solander)隶属于软体动物门腹足纲(Gastropoda)、原始腹足日(Archaeogastropoda)、蝾螺科(Turbinidae),分布于日本北海道南部以南沿海、南朝鲜和我国浙江以南沿海,是一种味鲜美、营养价值很高的经济贝类。有关角蝾螺的生物学,日本和南朝鲜均有详细报道。但我国关于角嵘螺生物学研究资料甚少,仅张玺等和董正之对其形态和分布作过简要地描述。我们于1984年4月至1985年5月对浙江沿海角蝾螺的分布、食性和生长等生态习性作了调查,现报告如下:更多还原

【Abstract】 The study on the ecological habit of Turbo cornutus solander in the Zhejiang coast was carried out from Apr. 1984 to June 1985. Turbo cornutus Solander is scattered only near the islands of remote sea area where the equal salinity 1ine is at 30‰ or so, and the transparency is good. Besides these, they live on the rock where algae are abundant, water is of high quality and what is more, the tidal current is unimpeded. The adults feed on Phaeophyta and Rhodophyta and the feeding intensity of the animal increases with the height of shells. The amount of dietary in terms of per unit of weight of animal decreases during the growth. The relationship between the body weight and the shell heiglit was obtained by the measurement and analysis of the 808 samples: W=3. 467×10^-4. H^{2. 9417} （r = 0. 9975）. The relarionship between the shell width and heiglit is D=0. 8792H-0. 2233 （r=0. 9838）. The relationship between the hight of aperture and the shell hight is H’=0. 6171H+0. 1783 （r=0. 9970）. In the natural sea area: Turbo cornutus Solander has a higher growing rate during the first years. The oldest animals （which were found） living about eight years.更多还原
