Bottom trawl surveys from Oneida Lake, NY, 1958 to present

This dataset contains trawl data from Oneida Lake, NY from 1958 to present and is part of the data set "Cornell Oneida Lake Data". The Cornell Biological Field Station (CBFS) serves as a primary field site for aquatic research at Cornell University (more information can be found at http://www.cbfs.dnr.cornell.edu) and is part of the Department of Natural Resources, College of Agriculture and Life Sciences, Cornell University. The centerpiece of the station's research program is a 60-year database on the food web of Oneida Lake, New York, that has been collected with support from the Cornell University Brown Endowment and from the New York State Department of Environmental Conservation. The data are collected by personnel from the Cornell Biological Field Station and include limnology, benthos, zooplankton, phytoplankton, and fish survey data from Oneida Lake and from 1957 to present. In addition to the 10 standard trawling sites, data from an additional seven shallow water sites that were sampled during 1971 and 1973 - 1977 are also reported in this dataset. The trawl summary table contains total catch, total weight, and mean weight data by species and age group (adult and young of year) for each sampling date. Weight is not available for all groups and time periods. Additional tables report catch per unit effort by year and age (1-6+ and 1-7+, respectively) for yellow perch and walleye. Auxiliary tables contain explanations of species codes and latitudes and longitudes for all sampling sites.
