Ag Data Commons migration begins October 18, 2023

The Ag Data Commons is migrating to a new platform – an institutional portal on Figshare. Starting October 18 the current system will be available for search and download only. Submissions will resume after the launch of our portal on Figshare in November. Stay tuned for details!

Data Extent

Data from: Evaluation of a snail trap prototype for monitoring the intermediate gastropod hosts of Bolbophorus spp. in commercial catfish ponds of the southeastern United States

This dataset provides information on collection abundances of snails from commercial catfish ponds in the Mississippi Delta Region. Snail trap data were collected from weekly trap (passive) checks and monthly collections (active) from a commercial catfish production facility, Snail species include Planorbella trivolvis, Biomphalaria havanensis, and Physa sp. Data include weekly collections from traps (unknown trapping range) and monthly collections from 1 sq. meter sampling grids.
