Summary
The data includes dates, places, and times of sampling events for eggs of invasive Grass Carp (Ctenopharyngodon idella) in tributaries to the Great Lakes in 2021 and 2022. Reference data on locations and dates sampled, gears used, and effort are included. Developmental stages for a subset of undamaged, fertilized eggs are provided. Tables include common fields to allow for integration into a relational database to aid data extraction and associating data among tables.

Purpose
The data were collected to determine when and where Grass Carp were spawning in Great Lakes tributaries. After reproduction in the Sandusky River was confirmed in 2015, sampling continued to generate data from sampled eggs, which were used in conjunction with hydraulic and fluvial drift models to predict and verify spawning areas. Data can be used to track egg numbers and densities in Great Lakes tributaries in support of population monitoring and management and for locating new spawning areas.
