Abstract

Bythotrephes longimanus is a predatory zooplankton native to Eurasia known for its large caudal spine. This species can decrease Daphnia abundance and may decrease growth rates of native planktivorous fish including yellow perch (Perca flavescens). Bythotrephes was first documented in Oneida Lake, USA in 2019 and reached high densities in 2020 and 2021. This recent invasion created an opportunity to investigate at what length yellow perch feed on Bythotrephes, if age-0 yellow perch select for Bythotrephes, and if yellow perch first-year growth decreased. We found Bythotrephes in the stomachs of 23% (2020) and 35% (2021) of age-1 and older yellow perch caught from June through September and 54% of the age-0 yellow perch caught from June through October (2021). Age-0 yellow perch started feeding on Bythotrephes at 27 mm and selected for Bythotrephes from June 24 through the autumn of 2021. Bythotrephes accounted for 54% of age-0 diets by dry weight over the summer and fall. We used the extensive water quality and biological monitoring data from Oneida Lake to develop a multivariate linear regression model for age-0 yellow perch October length from 1993 to 2021. Significant variables included were age-0 yellow perch abundance (negative effect) and temperature, Daphnia biomass, and Bythotrephes presence, all positive effects. Contrary to our expectations, Bythotrephes were selected by age-0 yellow perch from end of June through October, and contributed a substantial proportion of ingested mass by age-0 perch, without negatively affecting age-0 yellow perch growth.

纽约奥奈达湖地区长柄胸圆线虫入侵对0龄黄鲈鱼日粮和生长的影响
长棘鱼是一种原产于欧亚大陆的掠食性浮游动物,以其巨大的尾鳍而闻名。该物种可以减少水蚤的丰度,并可能降低本地浮游食性鱼类包括黄鲈的生长速度。Bythotrephes于2019年首次在美国的奥奈达湖被记录,并在2020年和2021年达到高密度。最近的入侵创造了一个机会来调查黄鲈鱼在多长时间内以Bythotrephes为食,0岁的黄鲈鱼是否选择Bythotrephes,以及黄鲈鱼第一年的生长是否减少。我们在6月至9月捕获的1岁及以上黄鲈的胃中发现了23%(2020年)和35%(2021年),在6月至10月(2021年)捕获的0岁黄鲈的胃中发现了54%的Bythotrephes。0岁的黄鲈在27毫米处开始以Bythotrephes为食,并从6月24日到2021年秋季选择为Bythotrephes。在夏季和秋季,按干重计算,食用鱼占0岁日粮的54%。利用奥奈达湖广泛的水质和生物监测数据,建立了1993 - 2021年0岁黄鲈10月长度的多元线性回归模型。显著变量包括0岁黄鲈丰度(负影响)和温度、水蚤生物量和蛭体存在,均为正影响。与我们的预期相反,从6月底到10月,0岁的黄鲈选择了Bythotrephes,并且贡献了0岁的黄鲈摄食质量的很大一部分,并且没有对0岁黄鲈的生长产生负面影响。

期刊介绍: Ecology of Freshwater Fish publishes original contributions on all aspects of fish ecology in freshwater environments, including lakes, reservoirs, rivers, and streams. Manuscripts involving ecologically-oriented studies of behavior, conservation, development, genetics, life history, physiology, and host-parasite interactions are welcomed. Studies involving population ecology and community ecology are also of interest, as are evolutionary approaches including studies of population biology, evolutionary ecology, behavioral ecology, and historical ecology. Papers addressing the life stages of anadromous and catadromous species in estuaries and inshore coastal zones are considered if they contribute to the general understanding of freshwater fish ecology. Theoretical and modeling studies are suitable if they generate testable hypotheses, as are those with implications for fisheries. Manuscripts presenting analyses of published data are considered if they produce novel conclusions or syntheses. The journal publishes articles, fresh perspectives, and reviews and, occasionally, the proceedings of conferences and symposia.
