Summary

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).

Purpose

These data were collected during the identification of Grass Carp eggs from bongo net samples. Egg size is a useful characteristic in the differentiation of Grass Carp eggs from those of native species within the Great Lakes basin. These eggs were on the smaller side of the known Grass Carp egg size spectrum and were documented to aid identification of Grass Carp eggs.
