| 摘 要： | 系统研究了以合浦珠母贝为饵料条件下毛嵌线螺的生长及捕食情况 .结果表明 :毛嵌线螺的壳高与体质量 (体重 )的关系为W =0 .54H2 .4 6;在合适的饵料生物充足的情况下 ,壳高 5mm左右的个体约经 60d的生长便可达到性成熟 ,其中以壳高 10～ 55mm阶段的生长速度最快 ,接近 1mm·d- 1;虽然不同大小的毛嵌线螺之间的绝对捕食量差异巨大 ,但其单位质量的相对捕食量基本符合Morton提出的 1%～ 6%的标准 .

| Abstract: | This paper systematically studies the growth and consumption of Cymatium pileare under the condition of feeding with Pinctada martensi. The result shows that the relationship between the height and body weight of C. pileare is W=0.54H2.46. When the prey is sufficient, individuals of the height of 5 mm will grow to be sexual mature in 60 days, and they will have the fastest growth rate of approximately 1 mm*d-1 when their shell height are10～55 mm. Though the absolute consumption of different sizes of C. pileare on P. martensii is greatly different, its relative consumption conforms to 1%～6% of its tissue weight as advanced by B. Morton. |
