Grass Carp (Ctenopharyngodon idella) Egg Diameter Estimates from the Huron River (Ohio), 2022

These data include egg diameter estimates from Grass Carp (Ctenopharyngodon idella) eggs collected during bongo net sampling in the Huron River (Ohio; 41.3305, -82.5812) on May 23, 2022 near Milan, Ohio. Egg diameters were estimated from photographs using proportional relationships of pixel lengths with a known length scale bar in millimeters. Given that eggs were not perfectly spherical, egg diameters were measured across two perpendicular axes and an average was calculated to represent an estimate of egg diameter (mm).本数据集包含2022年5月23日于俄亥俄州米兰附近休伦河（俄亥俄；41.3305, -82.5812）采用邦戈网（bongo net）采集的草鱼（Grass Carp, Ctenopharyngodon idella）鱼卵直径估算数据。研究人员通过拍摄的照片，结合已知毫米级长度标尺的像素长度比例关系估算鱼卵直径。由于鱼卵并非完美球形，研究人员对两条互相垂直轴线上的直径进行测量，并取平均值作为鱼卵直径的估算值（单位：毫米）。
