Seining collections were made an ten lakes in the region during the segment reported. During this period, largemeuth bass were stocked in Whitney, Pat Cleburne and Moss Lakes, and channel catfish were stocked in Amen Carter Lake near Bowie: All the lakes checked have sufficient forage to support game fish populations. 'With the exception of a few rises, due to spring rains, the water levels remained fairly constant in all lakes.

Only one largemouth bass was taken in the collecti This four-inch specimen was taken near the dam and represented successful reproduction. Even though no channel catfish were taken in the collections, there were several re- ports that a good population existed in the lake. No recommendations were made to stock additional fish. Lake Grapevine Six seining collections, made at various points on the lake, took a total of 260 fish of eight species (Table 3). Brook silversides alone comprised more than 70 per cent of the total number of fish taken. Collectively, red and blacktail shiners comprised more than 25 per cent by number. Thus there is sufficient forage in the lake. Three largemouth bass, ranging from two and one—half to three and one-fourth inches, were taken in the seining collections. These fish indicate successful repro- duction. No recommendations were made to stock either bass or catfish. Lake Whitney In December 1965, ten seining collections were made on Lake Whitney. In all, lespecnmn1 were taken (Table 4). Bullhead minnows comprised more than 50 per cent by number. Red and blacktail shiners together comprised more than 20 per cent by number. Thus it seems that there is sufficient forage in the lake. Even though four specimens were taken in the seines, it was decided to stock 280,000 largemouth bass. These fish were supplied by the Eagle Mountain State Fish Hatchery near Fort Worth. Benbrook Lake In December 1965, six seining collections were made on this lake. All told, 253 fish of 10 species were taken (Table 5). Blacktail shiners, red shiners and golden shiners, in that order, were the most abundant species taken. Together, they represented over 86 per cent of the total fish taken. In addition, 91 freshwater shrimp were collected in the six seining collections. Thus, there is ample forage in the lake. Three specimens of largemouth bass, from 3 to 4 inches long; were taken in the seining collections. These fish represent successful reproduction in the lake. In April, heavy rains on the watershed caused the lake level to rise about 10 feet. Otherwise, the lake level remained constant during the study period. No recommendations were made to stock either bass or catfish. Table 4.

All together, 372 fish of 10 species were taken (Table 6). Blacktail shiners alone com- prised 87.90 per cent by number. These fish ranged from oneuhalf to three inches in length. Since these fish are good forage, there seems to be ample food in the lake. Two specimens of largemouth bass, ranging from three and onemhalf to five inches, were taken in the seining collections. These fingerlings represent success“ ful reproduction. No recommendations were made to stock either largemouth bass or channel catfish. Amon Carter Lake Four seining collections were made on this lake. Two were made in March and two in June. Results are shown in Table 7. Only three species of fish were taken in the March collections. In these collections, blacktail shiners comprised 50 per cent by number and red shiners 35 per cent by number. However, in the June collections, no blacktail shiners were taken. Brook silversides comprised more than 64 per cent by number and bluegill comprised more than 14 per cent by number. Four largemouth bass were taken representing 7.14 per cent of the total. These fish, from one and a half to six inches long, represented successful reproduction. No recommendations were made to stock largemouth bass, but 8,000 channel cat- fish were stocked. The fish were stocked in the latter part of October 1966, and ranged from four to eight inches in length. Lake Bridgeport Nine seining collections were made in March and June and results are shown in Table 8. Red shiners, brook silversides, mosquitofish and gizzard shad, in that order, comprised 84.33 per cent by number. One white bass, l3 largemouth bass and two white crappie were taken in the collections. The largemouth bass, which were taken in the June collections. ranged from one and a half to three and a half inches in length. Obiously these fish were spawned in the lake and represented successful reproduction. Also, evidence was found to indicate that the white crappie had spawned. Two crappie, ranging from three and a fourth to five inches, were taken in the seining collections. The water level was normal when the seining collections were made in March, but it was above normal in June. Heavy rains on the watershed in June filled the lake to capacity and caused it to be about 15 feet above its normal level. Since sufficient evidence of a good game fish population was found, no recommen- dations were made to stock either largemouth bass or channel catfish. Nocona Lake In June 1966, three seining collections were made on this lake. All told, 236 fish of five Species were taken (Table 9). Brook silversides comprised more than Table 6.
