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 at Cornell University. 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 the CBFS estimates of walleye abundance at different stage and age groups in Oneida Lake. These estimates are based on data from standard trawl (1961-2008; http://hdl.handle.net/1813/11217) and gill net catches (1959-2008; http://hdl.handle.net/1813/11216), mark-recapture estimates for age 4 and older walleye, an analysis combining these data sets (Irwin et al. 2008), Miller sampler surveys for larval walleye, and information from the Constantia Fish Cultural Station on number of newly hatched larval walleye stocked each year. There are two primary data tables: one with the estimated abundance in # fish/ha for age 1 and older walleye in April of each year, and one with estimated abundance, length, and sampling dates for age-0 walleye (larvae, juveniles, age-1 in the following spring). An additional table, catchability, contains numbers used to estimate walleye abundance as described in the methods section.
