Abstract

ABSTRACT In this study, the length-weight relationship (LWR) was determined for the marine gastropod and commercial fisheries species, Kellet's whelk (Kelletia kelletii), and possible site- and sex-based differences in the LWR were assessed. Data were collected from 761 Kellet's whelks (1.6–15.5cm shell length, 0.51–404g total weight) that were brought to port by commercial fishermen or collected using SCUBA from three regions across the US geographic distribution of the species: San Diego, Santa Barbara, including the Northern Channel Islands, and Monterey. Model fitting revealed a cubic function to represent the LWR of the entire dataset with strong explanatory power. The fitted model suggested the species demonstrates slightly negative allometric growth, indicating that shell length grows faster than the width of the organism. Whelk sex and collection site did not impact the LWR. The information from this study can be used to inform management decisions for Kellet's whelk conservation, aquaculture, and fisheries harvest and guide future research.

海带森林腹足类和新兴渔业物种 Kellet's Whelk（Kelletia kelletii）的长度-重量关系

摘要在这项研究中，确定了海洋腹足类和商业渔业物种凯氏螺（Kelletia kelletii）的长度-重量关系（LWR），并评估了长度-重量关系中可能存在的地点和性别差异。数据收集自 761 颗 Kellet 螺（壳长 1.6-15.5 厘米，总重 0.51-404 克），这些螺由商业渔民带到港口，或使用 SCUBA 从美国该物种地理分布的三个地区收集：圣地亚哥、圣巴巴拉（包括北海峡群岛）和蒙特雷。模型拟合显示，一个立方函数代表了整个数据集的 LWR，具有很强的解释力。拟合模型表明，该物种表现出轻微的负异速增长，这表明贝壳长度的增长快于生物体宽度的增长。螺的性别和采集地点对长宽比没有影响。这项研究的信息可用于为凯氏螺保护、水产养殖和渔业捕捞的管理决策提供依据，并指导未来的研究。
