--- Page 1 --- STATE Texas PROJECT NO. FOR3 - Job B-4 PERIOD July 1, 1955 - June 30, 1956 Segment Completion Report Alvin Flury - Project Leader Lou Guerra - Assistant Project Leader TITLE Inventory of Fish Species Present in Falcon Reservoir. OBJECTIVES To determine the species present and their relative numbers in Falcon Reservoir. PROCEDURE A. Netting Collections. 1. Ten stations were selected on Falcon Reservoir to represent different locations and ecological conditions. A total of 120 experimental gill nets were set from July 1, 1955 to June 30, 1956. When possible nets were set at each station at monthly intervals. 2. All fish taken in nets were weighed, measured, sexed, and parasites noted. Scales failed to yield any signs by which age could be determined. There were 123 stomachs taken and preserved for later laboratory study. B. Seining Collections. 1. Six seining collections were made at the three available beaches, with a 30 by 6 foot bag seine. Three rotenone collections were made chiefly in an effort to recover bass fry. C. Data collected on netting and seining collections was recorded on fish cards and collection sheets. These were filed for further study, tabulation, and analysis. RESULTS A. Netting Collections. 1. A total of 1,701 specimens of twenty-one species was taken in 120 experimental gill net sets. (Table 3). 2. The data collected was filed and the "K" factors and stomach analysis will be presented in the job completion report. B. Seining Collections. --- Page 2 --- 1. A total of 5,640 fish of thirty-three species was taken in six seining and three rotenone collections. C. All data observed and recorded in making the netting and seining collect~ ions was filed and will be used later in making detailed charts and tables for the job completion report. A total of thirty-six species of fish have been recorded during this segment from Falcon Reservoir. Their frequency of occurrence is shown on Table 2. SUMMARY One hundred and twenty experimental gill net sets, six seining, and three rotenone collections were made in Falcon Reservoir during this segment. Because of the flucuating water levels, inflow of flood waters, and general periods of un- stable water stages this job was amended to be extended for one more year. Fish collected were weighed, measured, sexed, and parasites noted. Stomach contents of some fish were preserved for later laboratory study. Thirty-six fish species have been recorded from Falcon Reservoir. Three tables are also included in this report. --- Page 3 --- Table 1. Species List From Falcon Reservoir.
