tabular digital data The Grass Carp Removal Program (GCR) is a component of the U.S. Fish and Wildlife Services (USFWS) Alpena Fish and Wildlife Conservation Office (FWCO) Aquatic Invasive Species (AIS) Program. The GCR Program began in 2018 as a multi-jurisdictional response strategy. Federal, state, and university partners are working collaboratively to suppress Grass Carp populations in Lake Erie and prevent their establishment elsewhere.Surveys have occurred annually from 2018- Present. Sampling focuses on rivers, wetlands, bays, and other nearshore areas of Lake Erie, Lake Michigan, and Lake Huron. Sampling focus, protocols, and priority locations are determined by the Grass Carp Advisory Committee (GCAC), a sub-committee of the Lake Erie Committee (LEC), and contributes to the shared goals of the Invasive Carp Regional Coordinating Committee (ICRCC).Standardized response sampling protocols for adult grass carp determine sampling gear, site selection, and sampling approach for each sampling event. Grass Carp are collected using a variety of sampling gears with the most utilized including: electrofishing, trammel nets, gill nets, and hoop nets. The sampling season generally occurs from April – December, however, not all locations are sampled on a similar temporal scale, particularly those locations that are not high priority. Sampling Protocols include Sustained, Exploratory, Spawning, Targeted, and Realtime Response strategies. This table contains grass carp capture data collected during sampling events and grass carp lab results. This dataset contains fisheries data collected in the Great Lakes and tributaries that help inform critical objectives of the Lake Erie Committee and the Grass Carp Advisory Committee. -89.593506 -75.179443 46.830134 41.013066 ISO 19115 Topic Categories biota environment None The United States Fish and Wildlife Service (Service) shall not be held liable for improper or incorrect use of the data described and/or contained herein.
