Abstract

Species-specific length-weight relationships can inform researchers and managers about the growth patterns and health of fish populations. Few length-weight relationships exist for Appalachian stream fish species despite the high amount of biodiversity within the region. The main purpose of our study was to determine the length-weight relationships for stream fish species found in Central Appalachia. We sampled 16 streams and captured over 14,000 individual fish among 44 species. We identified each fish to species and recorded total length (mm) and weight (g) for each individual. These data were log10 transformed and analyzed using linear regression to calculate the length-weight parameters for each species. Relationships were calculated for 44 different stream fish species. Searches in FishBase.org revealed that of the 44 species in our data, 9 species have no current data in FishBase.org (Froese and Pauly, 2016), while 20 others have no previous representation from Central Appalachia. The relationships obtained in this study are some of the first published for these species in this region. Availability of species- and region-specific data on length-weight relationships could help inform future research and management of these species.

阿巴拉契亚中部 44 种鱼类的长度-重量关系

特定物种的长度-重量关系可以让研究人员和管理人员了解鱼类种群的生长模式和健康状况。尽管阿巴拉契亚地区生物多样性丰富，但该地区溪流鱼类物种的长度重量关系却很少存在。我们研究的主要目的是确定阿巴拉契亚中部溪流鱼类物种的长度-重量关系。我们对 16 条溪流进行了采样，捕获了 44 个物种中的 14,000 多条鱼。我们确定了每条鱼的种类，并记录了每条鱼的总长度（毫米）和重量（克）。这些数据经过对数 10 转换后，使用线性回归分析法计算出每个物种的长度-重量参数。计算出了 44 种不同溪流鱼类的关系。在 FishBase.org 中搜索发现，在我们数据中的 44 个物种中，有 9 个物种目前在 FishBase.org 中没有数据（Froese 和 Pauly，2016 年），而其他 20 个物种以前在阿巴拉契亚中部没有代表。本研究中获得的物种关系是该地区首次公布的物种关系。提供特定物种和地区的长度-重量关系数据有助于为这些物种的未来研究和管理提供信息。
