Evaluation of avoidance behavior of tadpole madtoms (Noturus gyrinus) as a surrogate to the endangered northern madtom (Noturus stigmosus) in response to granular Bayluscide®

The objective of this study was to document the vertical avoidance behavior of the tadpole madtom, as a surrogate to the northern madtom, in response to granular Bayluscide® when applied to control or assess larval sea lamprey populations. The data set consists of one hour recordings of the avoidance behavior of tadpole madtoms after exposure to granular Bayluscide. Each trial (replicated 15 times) consisted of three treated (Bayluscide granules) and three control (washed sand only) clear Plexiglas vertical columns (107 cm in height, 30.5 cm in diameter) with a single madtom per column. Video recordings were analyzed for vertical avoidance at 30 second intervals after addition of Bayluscide granules/washed sand over a period of one hour. Vertical migration of the normally bottom dwelling madtoms to greater than 15 centimeters off the bottom of the column was considered avoidance.

本研究旨在以蝌蚪𬶏（tadpole madtom）作为北方𬶏的替代物种，记录其在暴露于颗粒状贝路亚杀（Bayluscide®）后的垂直躲避行为——该药剂常被用于防治或评估海七鳃鳗（sea lamprey）幼虫种群。本数据集包含蝌蚪𬶏暴露于颗粒状贝路亚杀后1小时的躲避行为录像。每项重复15次的试验包含3个药剂处理组（投放颗粒状贝路亚杀）与3个对照组（仅投放清洗过的砂），试验容器为高107厘米、直径30.5厘米的透明有机玻璃（Plexiglas）垂直柱，每柱投放1尾𬶏。在投放药剂或清洗砂后的1小时内，每隔30秒对录像进行分析以统计垂直躲避行为。当原本底栖的𬶏移动至距离柱底15厘米以上的水层时，即被判定为发生躲避行为。
