Abstract

We used bomb calorimetry to quantify the energy density of three fish species endemic to Bear Lake, Utah-Idaho that were collected in 2020 – 2021. We collected Bear Lake Whitefish Prosopium abyssicola , Bonneville Whitefish P. spilonotus , and Bonneville Cisco P. gemmifer . We found that mean (± standard deviation) wet weight energy densities were 6,312 (± 760) joules per gram for Bear Lake Whitefish, 5,301 (± 778) joules per gram for Bonneville Whitefish, and 4,743 (± 443) joules per gram for Bonneville Cisco. We built linear mixed models and found relationships between energy density and dry matter ratio (i.e., ratio of dried weight to wet weight of a fish) for all three species, suggesting that the energy density of future samples collected in Bear Lake could potentially be determined from comparisons between the dried and wet weight of fishes belonging to these species. Our results will be useful for future bioenergetics modeling with these three Bear Lake endemic species, and potentially with others species in related genera that share similar feeding, behavior, and life history traits.

犹他州-爱达荷州熊湖特有的三种前鸦片鱼类的能量密度

我们使用炸弹量热法量化了2020 - 2021年收集的犹他州-爱达荷州熊湖特有的三种鱼类的能量密度。我们采集了熊湖白鱼Prosopium abyssicola、Bonneville Whitefish P. spilonotus和Bonneville Cisco P. gemmifer。我们发现熊湖白鱼的平均(±标准差)湿重能量密度为6312(±760)焦耳/克，博纳维尔白鱼为5301(±778)焦耳/克，博纳维尔思科为4743(±443)焦耳/克。我们建立了线性混合模型，并发现了所有三种鱼类的能量密度与干物质比(即鱼的干重与湿重之比)之间的关系，这表明未来在熊湖收集的样本的能量密度可能会通过比较属于这些物种的鱼的干重和湿重来确定。我们的研究结果将有助于未来对这三种熊湖特有物种的生物能量学建模，以及对具有相似摄食、行为和生活史特征的其他相关属物种的生物能量学建模。

期刊介绍： Journal of Fish and Wildlife Management encourages submission of original, high quality, English-language scientific papers on the practical application and integration of science to conservation and management of native North American fish, wildlife, plants and their habitats in the following categories: Articles, Notes, Surveys and Issues and Perspectives. Papers that do not relate directly to native North American fish, wildlife plants or their habitats may be considered if they highlight species that are closely related to, or conservation issues that are germane to, those in North America.
