| 摘 要： | 本文报导了采自舟山沿海单齿螺种群的年龄结构、生物量与生长。自然种群的单齿螺年龄组成以１＾＋和２＾＋龄占优势，壳高、壳宽、壳口高、厣径、体重等生长参数的回归关系良好，单齿螺的生长完全可以用壳高来表示。单齿螺以第一、二年生长最快。采捕季节可定在四、五月间，采捕规格应在壳高１６ｍｍ以上。

| Abstract: | This paper embodies the growth and composed population of Monodonta labio collected from the rocky shore of intertidal zone of zhoushan archipelago. 1+ and 2+ year classes were the main composition in the natural group. The regression relations among growth kinetic paramenters of shell height, shell width, aperture height, operculum diameter and weight were good. All of the other kinetic paramenters could be replaced by the paramenter of shell height. The growth rate was liigh in the 1+ -2+ year classes. Shell height over 16mm is suitable for capture from April to May every year. |
