34 <br />1979 Field Data Summary <br />The data needed considerable organization at the end of the season. <br />Considerablejeffort was spent to reorganize the data into a meaningful <br />format so it could be placed into the MANAGE data base (the MANAGE Data <br />sets were not worked out until after the sampling season). Next season <br />data will be collected in a manner that will simplify entry into the <br />MANAGE system. <br />A total of24 intensive 0.5 mile sample stations, and 10 electrofishing <br />stations were sampled under the systematic sampling program in 1979. <br />Table 6 presents a list of all fishes captured b?,, strata. During 1979, <br />20 different species were collected. <br />At Stratum B (Gunnison Butte to Labyrinth Canyon), seine collections <br />were made during three time periods: 1900-0100, 0100-1300 and 13004900--- <br />hours. These collections were made in an effort to determine if sampling <br />should be conducted between 0100-0700 hours. Figure 6 illustrates the------ <br />extreme fluctuations in catch per unit of effort for the most common- <br />fish species, red shiners. Catch rates for red shiners were lowest <br />between 0100-0700. In addition, a chi-square analysis indicated there <br />were no significant differences (95% level) in the number of species <br />collected when the three time periods were compared. <br />Because of the generally high level of variance associated with seine <br />catches and lack of indication that the time period 0100-0700 was different <br />in catches of fishes, we decided it was not necessary to treat time <br />periods differently for seine catches, and would exclude the 0100-0700 <br />period from the diurnal sampling time frame.
