Display Field: SAMPLEID
Type: Feature Layer
Geometry Type: esriGeometryPoint
Description: This layer contains data collected by the University of Maryland conducted seine and trawl surveys in the Choptank River from 2010-2013 (Houde et al., 2014), with the majority of the sampling effort occurring in 2012 and 2013. The primary purpose of the study was to compare the catch efficiency of Atlantic menhaden using beach seine and midwater trawl methods. Six sites were designated in the Choptank River along a salinity gradient. At each site, seine hauls were conducted using the same protocol as MD DNR. Simultaneous mid-water trawls were conducted <0.5 km off shore of the beach seine locations. The duration of the trawl was 20 minutes, with the net fished from surface to bottom in two-minute step increments. All fish caught in the gear were identified to species and counted. This layer contains the location of seine and trawl surveys and fish counts from for each station and sample date, represented as points.
