Inventory of Species (seining stations were selected). 10 Data was collected including a tally for each species taken as well as ecological information concerning each specieso 2, Temperature, pH, turbidity, dissolved oxygen and carbon dioxide were determined at every station, 3a Netting collections were made at stations selected during the course of the worko FINDINGS: Because of many difficulties encountered in completing other river surveys; (iceo the Upper Colorado River and the Pecos River watersheds) the only data and specimens Obtained thus far were taken from stream areas immediately above Lake Trammel near Lake Sweetwater, below Fort Phantom Hill Reservoir, near Abilene and from the watershed near Buffalo Gapo Netting was possible only above Lake Trammele Netting - Netting results as presented below are obviously fragmentaryo The sunfish grouped were one bluegill and one green sunfish, Two experimental gill nets were set in the above described localityo Numerical Avgo Wto Percent Species Noe Percent ounces by Wto Avgo K Largemouth Bass 1 5126 18 12033 echo Channel Catfish 1 5,26 2h 14073 2°3u Sunfish 2 10654 3 3015 Lois Gizsard Shad 12 63,16 A 25,66 1,86 River Carpsuckers 3 15,78 28 hho2l 2o5h Seining w Seining collections were taken at six localities within the above desu cribed areas of the watershedo It is believed that numerical results may be misleading because it was difficult to locate areas where stone or brush obstructions on the stream bottom did not prevent or render ineffective this method of sampling and because the samll number of specimens obtained is regarded as insufficient even for the localities where collection work was possible, For these reasons a species check list with comment is regarded as being more suitable for this particular report, Seining Check List Gizzard Shad (Dorosoma cepedianum) m numerous although difficult to capture by seiningo These fish were observed in schools above Lake Trammel and below Fort Phantom Hill Reservoir, River Carpsucker (Carpiodes carpio) - collected below Fort Phantom Hill Reservoir onlyo Carp (Cyprinus carpio)m Collected below Fort Phantom Hill Reservoir onlyo Redhorse Shiner (Notropis lutrensis) a particularly numerous in the stream areas near Buffalo Gap; however, this species was taken at all three areaso Plains Shiner (Notropis percobromus) m Above lake Trammel and near Buffalo Gap but not in collections below Fort Phantom Hill Reservoiro Channel Catfish (Ictalurus punctatus) m taken below Fort Phantom Hill only, Largemouth Bass (Micropterus salmoides)= in all collections, but rare» LA.) Bluegill (Lepomis macrochirus)- numerous in all collectionso Green Sunfish (Lepomis cyanellus) n numerous in all collections, White Crappie (Pomoxis annularis) — present above Lake Trammel only. Black Crappie (Pomoxis nigromaculatus) - Lake Trammel only, Logperch (Porcine caprodes) ~ below Fort Phantom Hill Reservoir only, RECOMMENDATIONS: It is recommended that this survey be discontinued at this time and be resumed in 1958—19590 ‘ ‘% Prepared by: Lawrence Do Campbell Approved by: cxgrenavaxr,/’ Project Leader Chief Aquatic Biologist Date: April 29, l958 \il/ -__._-—-_-_ .—¢-. m 1....-_ __,.
