To determine the fish species present, their relative abundance and the factors influencing their distribution. 2. To compare the fish population in Hubbard Creek Lake (pre-impoundment rotenone treatment of watershed) with that of Proctor Lake (untreated watershed) to determine the following: a. Rough fish-game fish ratio. b. Growth rates (based on length of time since stocking). c. Coefficient of condition of game species, d. Reproduction of game species. Procedures: Experimental gill nets were set at eight permanent stations on both Hubbard Creek and Proctor Lakes on a bimonthly basis. Original plans called for quarterly visits to each lake, but after some additional thought, it was felt that bimonthly visits would yield more data. Since no seining data were available for the previous segments, it was decided that such information would be of little value for the current segment. Therefore, no seining collections were made. Water analyses were made on each lake at an established station. Tests were made to determine dissolved oxygen, carodon dioxide, pH, and alkalinity. Results: During this segment, 48 netting collections were made on both Hubbard Creek and Proctor Lakes. Briefly, the results of the netting were as follows: --- Page 4 --- -2- Hubbard Creek Proctor Per Cent Per Cent Per Cent Per Cent of of of of Number _ Weight _ Number __ Weight _ Rough Species: 45.15 62.84 54. 34 57.43 Game Species: 34.41 35% 21 37.90 41.48 Miscellaneous Species: 20.44 1.95 _ 7276 1.09 TOTAL: 100,00 100.00 100.00 100.00 Table 1 lists the fish species included in the various categories of "rough species, game species and miscellaneous species", A detailed analysis of all data obtained during three segments of this job will be prepared and submitted for publication in the Inland Fisheries Series (F-4-R-14, Job B-36).
