Effects Of Predation And Environment On Quality Of Yellow Perch And Bluegill Populations In Nebraska Sandhill Lakes, Craig P. Paukert, David W. Willis, Joel A. Klammer

We investigated factors that may influence the quality (e.g., high abundance, size structure, condition, and growth) of yellow perch Perca flavescens and bluegill Lepomis macrochirus populations in Nebraska sandhill lakes. Physical (e.g., lake depth, vegetation coverage), chemical (e.g., alkalinity, conductivity), and biological (e.g., chlorophyll a, invertebrate abundance) characteristics of 30 natural lakes were determined in 1998 and 1999. Growth, condition, and size structure were not density-dependent for bluegills or yellow perch in these shallow (,4mmaximum depth) lakes. However, bluegill abundance, size structure, and condition were positively related to yellow perch abundance, size structure, and condition. Bluegill quality tended to …

The title of today' s session is Game Ranching: Boon or Bane? What do we mean by game ranching? For today' s discussions, we will look at the raising of traditional wildlife species, both native and exotic, behind high-wire fences for economic return. Many years ago, this was considered a Texas problem and most state wildlife agencies did not pay much attention to the growing trend of fencing large acreages to hold wildlife captive. It was contrary to the traditional view of game management and many thought that it was just a passing fad. Today, there are thousands of captive …
