Data and Code Release: Acute Toxicity of Lampricides to Non-target Species of Concern in the Lake Champlain Watershed

Data to evaluate the Acute Toxicity of Lampricides to Non-target Species of Concern in the Lake Champlain Watershed. The toxicity of the lampricides TFM and TFM/1% Niclosamide to numerous non-target fishes of concern in the Great Lakes has been presented in previous studies. However, not many toxicity studies have been reported for Finger Lakes and Lake Champlain species of concern including: the fluted shell mussel (Lasmigona costata), the pocketbook mussel (Lampsilis ovata), the black sandshell mussel (Ligumia recta), the cylindrical papershell mussel (Anodontoides ferussacianus), young-of-year quillback (Carpiodes cyprinus), eastern sand darter (Ammocrypta pellucida), the channel darter (Percina copelandi), American brook lamprey (Lethenteron appendix), margined madtom (Noturus insignis), stonecat (Noturus flavus), and the mudpuppy (Necturus maculosus). We exposed these mussels, fishes and amphibians to lampricides for 12 hours at concentrations bracketing the minimum lethal concentrations (MLC) required to achieve successful control of larval sea lamprey (Petromyzon marinus), and plotted the resulting non-target mortalities (NOEC, LOEC, LC25, LC50) against the lampricide concentrations expressed as a multiple of the sea lamprey field determined LC99.9. Herein, we describe the results of toxicity tests that evaluate the potential acute impacts on the non-target organisms discussed above.

本数据集用于评估尚普兰湖流域内受关注非目标物种对杀七鳃鳗剂（lampricides）的急性毒性。既往研究已报道了杀七鳃鳗剂TFM以及TFM/1%氯硝柳胺（Niclosamide）对五大湖地区多种受关注非目标鱼类的毒性。然而，针对手指湖群和尚普兰湖流域受关注物种的毒性研究较为匮乏，这些物种包括：褶纹壳蚌（Lasmigona costata）、囊形珍珠蚌（Lampsilis ovata）、黑砂壳蚌（Ligumia recta）、圆柱形薄壳蚌（Anodontoides ferussacianus）、当年生铜色吸口鲤（Carpiodes cyprinus）、东方沙鲈（Ammocrypta pellucida）、河道沙鲈（Percina copelandi）、美洲溪七鳃鳗（Lethenteron appendix）、缘石鮰（Noturus insignis）、石猫鮰（Noturus flavus）以及泥螈（Necturus maculosus）。我们将上述蚌类、鱼类与两栖动物暴露于杀七鳃鳗剂中12小时，暴露浓度覆盖了成功防控海七鳃鳗幼体（Petromyzon marinus）所需的最低致死浓度（MLC）区间；随后以海七鳃鳗野外测定的99.9%致死浓度（LC99.9）的倍数表示杀七鳃鳗剂浓度，并绘制了所得非目标生物死亡率相关指标（无观察效应浓度NOEC、最低观察效应浓度LOEC、25%致死浓度LC25、半数致死浓度LC50）与该浓度的关系曲线。本文阐述了针对上述非目标生物的急性影响毒性测试的研究结果。
