Figures & data
Table 1 Comparison of catch per unit effort in 3 Nebraska waterbodies pre- and post- rehabilitation for largemouth bass (fish/h electrofishing) and bluegill (fish/net-night). Comparisons were made within size groups derived from Gabelhouse (Citation1984). The length groups assessed were stock-length (S) fish, stock- to quality-length (S-Q) fish, quality- to preferred-length (Q-P) fish, preferred- to memorable-length (P-M) fish, and memorable- to trophy-length (M-T) fish. Welch's one-tailed t-tests were used in all comparisons. ND denotes inadequate data to carry out the test and * denotes significant result.
Table 2 Statistical results of comparison (Kolmogorov–Smirnov test) of length distributions in three Nebraska waterbodies pre- and post-rehabilitation. Length distribution data were grouped across years for each period (i.e., pre- and post- rehabilitation). The alternative hypothesis for each test was that the pre-rehabilitation length distribution was less than the post-rehabilitation length data. ND denotes inadequate data to carry out the test.
Table 3 Comparison of pre- and post-rehabilitation catch per unit effort (CPUE ± 95% CI) and the CPUE estimates for lakes and reservoirs of similar type across Nebraska (ecosystem CPUE ± 95% CI). A single ecosystem CPUE value (i.e., control) was used that incorporated the long-term variability in each ecosystem type including sandpit or dugout lakes, Sandhill ecoregion lakes, and flood control reservoirs. The t-value is calculated by comparing 2 means with degrees of freedom (df) and the P-value associated with each test. A t-value greater than the critical t-value of 1.96 indicates a statistically significant difference between the means. * indicates a change in CPUE occurred between pre- and post-rehabilitation compared to the long-term ecosystem average; ND denotes inadequate data to carry out the test.
