“duh-o. .. . Report of Fisheries Investigations Resurvey of the waters of Region 6-B by John E. Tilton Project Leader Gary wood Assistant Project Leader Dingell-Johnson Project F-2-R—7, Jab 3-20 . February 1, 1959 - January 3l, 1960 H. D. Dodgen - Executive Secretary Texas Game and Fish Commission Austin, Texas Marion Toole Kenneth C. Jurgens & William H. Brown Coordinator Assistant Coordinators --___-ABSTRACT 'i A resurvey of Lake Inks, Granite Shoals, Buchanan, Bolton, Marble Falls, and Austin, as well as the Brazos and San Gabriel Rivers, was carried out during 1959. Seventeen seine, 8h experimental gill net, and two rotenone collections were made on Inks Lake. The fish population was found to be similar to previous surveys, although some changes were noted in the rough fish complex. Gizzard shad showed a substantial drop in relative abundance in the netting results but rotenone samples revealed much higher population figures. Catfish and white bass dominated the game fish catch. The important largemouth bass is presumably still at a minimal population level as net and seine collections produced very few individuals. ' The results of 23 net sets on Lake Granite Shoals reveal very high rough fish population, but low population figures for gizzard shad. Smallmouth buffalo were the most abundant species taken, accounting for 33 percent of total numbers and 56 percent of total weight. The game fish population is con- sidered adequate and fishing remains good. The vegetation problem remains acute, but no control measures are considered economically feasible at this time. Fifty—two net sets were made on Lake Buchanan. Rough fish accounted for over 72 percent of total numbers and 78 percent of total weight. Gizzard shad made up 5h percent of total fish taken. Game fish, including channel catfish, white bass, largemouth bass and white crappie, support heavy fishing pressure on the lake. No management practices are recommended at this time. Seine collections on the Brazos River produced 5 species not taken in the original survey of the river including Notropis venustus, Notimogus crysoleucas, Ictalurus males, Lepomis punctatus and Lepomis microlophus. Thirty—eight net sets and nine seine collections showed substantially the same fish population as had been taken in previous surveys. A limited creel census was undertaken in an effort to check the catch of white crappie from Lake Belton. The census showed 1,581 anglers fished a total of 6,872. 5 hours and caught h ,9hh fish, for a fish/man hour total of O. 72. The crappie were small and few fishermen utilized the in- creased bag limit on this species. Gizzard shad showed a definite decrease in relative abundance, but no reason for the decrease could be ascertained. Work on the San Gabriel River and Lakes Austin and Marble Falls was too limited for comparison with previous collections and the data gathered will be included in later reports.
