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.dnr.cornell.edu/fieldst/cbfs.htm) and is part of the Department of Natural Resources, College of Agriculture and Life Sciences. The centerpiece of the station's research program is a 50-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, primarily from Oneida Lake and spanning 1957 to the present. This dataset reports data collected during standardized trawl sampling efforts at ten sites on Oneida Lake in central New York State from 1961 to 2006. 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 the ten standard sampling sites as well as the seven additional sites that were sampled in the 1970s.
