Gut content analyses have found that round gobies (Neogobius melanostomus) are highly dependent on dreissenid mussels but stable isotope analysis has often suggested that the dreissenid contribution is lower. However, estimation of dietary contributi

Recruitment of fish to the adult stock is often determined early in life, and identifying relationships between first-year abundance and subsequent recruitment has significant implications for monitoring and management. Despite the importance of Whit

Piscivorous birds, in particular cormorants Phalacrocorax spp., have been reported to cause declines in some fish populations in both Europe and North America, but not in others. This difference may be due to prey selection by cormorants that is furt

Fish egg sizes vary intra-specifically among stocks and individuals, and such variation may reflect a combination of maternal and environmental influences. As egg size variation has important implications for individual and population recruitment suc

We present long-term (>40-year) patterns in the density of age-0 yellow perch Perca flavescens in Oneida Lake at four early life stages (at egg deposition, at the attainment of a total length of 18 mm, on 1 August, and on 15 October), from which we c

Assessment of predator–prey dynamics is a central feature of community-based fisheries management, and a variety of fish condition indices have been developed from length–weight data to make inferences about feeding conditions. Relative weight (W

Daily consumption was estimated from the stomach contents of walleyes Sander vitreus collected weekly from Oneida Lake, New York, during June-October 1975, 1992, 1993, and 1994 for one to four age-groups per year. Field rations were highly variable b

We used three long-term data sets (gill nets, trawls, and adult population estimates) for walleye (Sander vitreus) to simultaneously estimate density, gear catchabilities, and mortality using an age-structured, nonlinear model. Model con- straints in
