Abstract

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.

哥打巴淡海域狗海螺（Canarium Linnaeus，1758）的长重关系、生长模式和性别比

本研究旨在分析海螺的体重关系长、生长模式和性别比。该研究于2018年5月至8月进行。样本是在哥打巴淡岛的三个地点(站)收集的，即Jaloh岛、Kangkung湾和Terong岛，这些地点成为捕获狗螺的主要地点。在3个研究站共采集到金丝雀377只(雄162只，雌215只)。雌性、雄性、混合在各站点的长权关系值分别为:Jaloh Island, W= 0,000142l 2,924, R²= 0.555(雌性)，W= 0,00049l 2,610, R²= 0.566(雄性)，W= 0,000165l 2,881, R²= 0.572(无斑点);康孔湾，W=0,0850 l 1,275, R²= 0.325(雌性)，0,00000511l 3,185, R²= 0.776(雄性)，W=0,0384 l 1,480, R²= 0.374(混合);与特龙岛一样，W=1,227L, 0.746, R²= 0.180(女性)，W=0,00139 l, 2,385, R²= 0.714(男性)，W=0,118L, 1,305, R²= 0.355(混合)。海螺的生长模式为负异速生长(b3)，其生长模式为正异速生长，其增重速度快于长增量。加罗岛和特龙岛的狗螺性别比平衡，而康公湾的狗螺性别比不平衡。总体而言，研究地区的性别比例不平衡，比例为1:1 .33，期望频率(Ei)为188.8。
