When pumpkinseeds were present, they tended to occur in deeper lakes and those with increased abundance of submergent vegetation.
The objectives of this project were to determine the characteristics of pumpkinseed populations sampled in several of those lakes, and to relate population characteristics to physicochemical and biological characteristics found at each lake.
Pumpkinseed population samples were obtained from seven Sandhills lakes in north-central Nebraska.
Minimum stock and quality lengths are 8 and 15 cm for bluegill and pumpkinseed, 13 and 20 cm for yellow perch, and 20 and 30 cm for largemouth bass.
Because we sampled only seven pumpkinseed populations and because these analyses were exploratory, we used an alpha level of 0.
The PSD for pumpkinseed population samples varied widely among lakes (Table 2), ranging from 0 to 71.
Pumpkinseed CPUE was positively related to lake maximum depth (r = 0.
Pumpkinseed PSD was not significantly correlated with largemouth bass mean CPUE (r = 0.
Pumpkinseed condition values followed similar trends as condition of both bluegills and yellow perch (Fig.
