本研究于2018年5月至8月进行，旨在分析犬螺体重关系的纵横长度、生长模式和性别比例。这些样本是从科塔巴淡岛主要捕捞狗螺的三个地点（站）采集的，即贾洛岛、康贡湾和特龙岛。共采集到377头（男162头，女215头）。橄榄是从三个研究站收集的。雌、雄、杂鱼各站体长-体重关系值分别为：贾洛岛，W=0，000142 L 2，924，R²= 0. 555（雌），W=0，00049 L 2，610，R²= 0. 566（雄），W=0，000165 L 2，881，R²= 0. 572（杂鱼）;康公湾，W= 0.0850L 1，275，R²= 0.325（雌性），0.0000511L 3，185，R²= 0.776（雄性），W= 0.0384L 1，480，R² = 0.374（混合）;以及Terong岛，W=1，227 L 0，746，R²= 0.180（女性），W=0，00139 L 2，385，R²= 0.714（男性）和W=0，118 L 1，305，R²= 0.355（混合）。狗螺的生长模式为负异速生长（B 3），具有正异速生长模式，其中体重增长快于长增量。在Jaloh岛和Terong岛，狗螺的性别比例是平衡的，而在Kangkung湾，它是不平衡的。总体而言，研究地点的性别比例不平衡，比例为1：1.33，预期频率（Ei）为188.8。
This study aims to analyze the aspect length of weight relationship, growth pattern, and sex ratio of Dog conch. This research was conducted in May-August 2018. The samples were collected from three locations (stations) which became the main of catching the Dog conch in Kota Batam, namely, Jaloh Island, Kangkung Bay, and Terong Island. A total of 377 individuals (162 males and 215 females) S. canarium were collected from three research stations. The value of the length-weight relationship for females, males, dan blended, at the respective station, are Jaloh Island, W=0,000142L 2,924 , R²= 0.555 (female), W=0,00049L 2,610 , R²= 0.566 (male), and W=0,000165L 2,881 , with a value of R²= 0.572 (blanded); Kangkung Bay, W=0,0850L 1,275 , R²= 0.325 (female), 0,00000511L 3,185 , R²= 0.776 (male), and W=0,0384L 1,480 , with R² = 0.374 (blended); As well as Terong Island, W=1,227L 0,746 , R²= 0.180 (female), W=0,00139L 2,385 , R²= 0.714 (male) and W=0,118L 1,305 with R²= 0.355 (blended). The pattern of growth of Dog conch is negative allometric (b 3) has a positive allometric growth pattern, where weight gain is faster than long increments. The sex ratio of Dog conch on Jaloh Island and Terong Island is balanced, while in Kangkung Bay it is not balanced. Overall the sex ratio in the study location is not balanced with a ratio of 1: 1.33 with the expectation frequency (Ei) of 188.8.
