This dataset contains walleye abundance at different stage and age groups in Oneida Lake and is part of the collection "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://cbfs.dnr.cornell.edu/index.html) 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 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, primarily from Oneida Lake from 1957 to the present. The walleye data are based on standard trawl (since 1961) and gill nets catches (since 1959) (Trawl Data-package and Gillnet Data- package), mark-recapture estimates for age 4 and older walleye, Miller sampler surveys for larval walleye, and information from the Constantia Fish Cultural Station on the number of 3-day-old larval walleye stocked each year. There are three data tables, one with the estimated abundance for age-1 and older walleye, the second with back-calculated length at annulus formation for males and females, the third with estimated abundance, length, and sampling dates for the first year of life (larvae, juveniles, age-1 in the following spring). An additional table gives the catchabilities for trawl and gillnets used in the calculations of abundance.
