| 摘 要： | 报道了宁波沿海珠带拟蟹守螺种群的年龄组成与生长情况．自然种群的珠带拟蟹守螺年龄组成以1龄和2龄占优势，壳高与壳宽、壳口高呈直线相关，壳高与体重呈幂函数相关．珠带拟蟹守螺壳高H)与壳宽(B)、壳口高(L)、体重(W)之间的回归关系为B=0．3325H 0．4831(r=0．9195)、L=0．2459H 1．3738(r=0．9224)、W=0．0002H^2.687(r=0．9781)．结果表明，宁波沿海珠带拟蟹守螺的生长完全可以用壳高来表示．

| Abstract: | The age composition and growth of Cerithidea cingulatus in Ningbo Coast are reported. The majority of the natural population consists of by 1 + and 2 + ages. Shell height and shell width, aperture height are linearly correleted the correlation between shell height and weight of body is the exponential. The regression equation of shell height(H,mm) and shell width(B,mm) is B=0.332 5 H+0.483 1(r=0.919 5), the regression equation of shell height(H,mm) and aperture height(L,mm) is L=0.245 9 H+1.373 8(r=0.922 4), the regression equation of shell height(H,mm) and the weight of body(W,g) is W=0.000 2 H 2.687 6 (r=0.978 1). The growth of Cerithidea cingulatus is indicated by the height. |
