The percid fishes (or perch family) comprise many species including the perch, pikeperch,
yellow perch, walleye and the darters. These species are of great ecological and economic …

Low survival rates during larval stages constitute a major bottleneck in the successful culture
of many marine and some freshwater fish. The availability of live food is recognized as a …

Zooplankton availability is strongly linked with the growth, survival, and ultimately
recruitment of fish during their early life history. We examined how different types of …

We examined prey preference, growth, and survival of small larval (8-10 mm total length
(TL)), large larval (11-17 mm TL), and early juvenile (> 18 mm TL) walleye (Stizostedion …

Each individual planktonic plant or animal is exposed to the hazards of starvation and risk of
predation, and each planktonic population is under the control of resource limitation from the …

Zooplankton are commonly used to establish a baseline isotopic signature for pelagic
production in lakes. Our objective was to evaluate this approach by quantifying among‐lake …

Do disparate mechanisms determine growth rates of fish larvae in the different regions? The
relationship between growth rates and environmental factors (sea temperature and food …

Some northern Wisconsin lakes have shown declines in catches of age‐0 Walleye Sander
vitreus in standardized fall electrofishing sampling, suggesting that recruitment bottlenecks …

Although larval fish can be highly susceptible to changes in prey availability, the effects on
growth and survival are difficult to examine in the field. In addition, previous studies often …

Young-of-the-year piscivores undergo ontogenetic diet shifts, but mechanisms influencing
prey selection and implications for growth are unclear. We examined foraging and growth of …
