The Bass-Bluegill Combination in a Small Artificial Lake

TEN years ago, Fork Lake, a pond of 1.38 acres on the farm of Paul S. Smith near Mount Zion, Illinois, Has probably typical of many of the older man-made ponds in central Illinois. When this pond was assigned for study to aquatic biologists of the Illinois Natural Histor\ Survey in 1938, it was 18 years old and had been used extensively for fishing, waterfowl shooting, and general outdoor recreation. A brief history of the recreational benefits derived from the pond has been published elsewhere (Thompson & Bennett 1939a). The Fork Lake experiment was terminated by run-off water from a 4-inch rain that washed out the dam on July 8, 1942. As no Natural History Survey personnel were present at the time the actual break occurred, fish collected were those that remained in the pond after about two thirds of the water had flowed out through the break, carrying with it a part of the fish population. In spite of this unfortunate circumstance, which eliminated the possibility of a final complete census of the fish, the partial census and the collections of previous years gave interesting and significant information on the bass-bluegill combination.published or submitted for publicationis peer reviewe

The Effects of Supplemental Feeding and Fall Drawdowns on the Largemouth Bass and Bluegills at Ridge Lake, Illinois

1.—After a draining census in 1963, Ridge Lake was restocked with 2,386 largemouth bass, 4,492 bluegills, 1,335 warmouths, 11 channel catfish, and 1,020 lake chubsuckers, making a total of 9,244 fishes weighing 510.6 kg (1,125.5 pounds). This was 78.8 kg per hectare, or 70.3 pounds per acre. In the census preceding this restocking this lake was found to contain 287 kg per hectare, or 256 pounds per acre, almost four times the weight of fish returned to the lake. In 1969, 2,000 additional channel catfish were stocked. 2.—The population of fishes was allowed to expand for two growing seasons (1963 and 1964) without drawdowns or supplemental feeding but with the usual controlled public fishing during the summer months. The hook-and-line catch in 1963 and 1964 was below the average for the preceding 20 years. 3.—Beginning in late May 1965, and continuing each year during the 3 summer months, 1965 through 1969, the fish were fed daily on a commercial pelleted fish food (32 percent protein) at the rate of 2 pounds per acre per day. Food was spread in the shallows in all parts of the lake. The food cost was within the range of $27.80-$30.12 per hectare per season ($11.25-$12.19 per acre per season). 4.—Each year, beginning in September 1965, the lake level was lowered: 4.6 meters (15 feet) in 1965, leaving a surface area of 2.12 ha 3.0 meters (10 feet) in 1966, leaving a surface area of 4.5 ha 3.0 meters (10 feet) in 1967, leaving a surface area of 4,5 ha 4.6 meters (15 feet) in 1968 leaving a surface area of 2,12 ha 4.3 meters (14 feet) in 1969, leaving a surface area of 2.76 ha The level was maintained until the water temperature in the lake was about 13° C, (57° F.) in October, when the lake was allowed to refill, 5,—In March 1970, the lake was drained to make a census of the fishes. The lake contained 2,420 bass, 9,546 bluegills, 556 warmouths, 1,477 channel catfish, 232 lake chubsuckers, and 3 fishes of other species, a total of 14,234 fishes weighing 1,440.0 kg (3,175.3 pounds). 6.—The catch of largemouth bass during the seasons 1965-1969, inclusive, was composed mostly of small fish. The f-d program resulted in the production of excessive numbers of small bass but generally did nothing to improve bass fishing. 7.—The fishermen's catch included more than twice as many large bluegills (152 mm or longer) as it did smaller ones during the 1965-1969 period. Blue gills of desirable sizes averaged 127 grams (0.28 pound) each. 8.—Neither warmouths nor channel catfish produced large hook-and-line yields because their numbers were always small. Channel catfish produced a small year class in 1963 or 1964, and this year class appeared in the catch in 1966-1969, inclusive. The catfish stocked in 1969 were too small to appear in the 1969 catch. 9.—During years when the water level in Ridge Lake remained fairly constant, bluegill numbers increased to 50,000 in one 2-year period and to 66,000 in another, to 86,000 in one 3-year period, and to 93,000 in a 4-year period. Annual fall drawdowns of 4.6 meters reduced the bluegill population to 7,500, those of 3.0 meters to 17,000 bluegills, and the 4.3- meter drawdown reduced the population to 9,500 bluegills. These drawdowns apparently had little effect on largemouth bass numbers. 10.—The average hook-and-line yield of bass in the 5 f-d years was only 18.0 kg per hectare (16.1 pounds per acre). This yield was below the average for 3 drawdown years (1952, 1954, and 1955) and 3 stable water level years (1957, 1958, and 1959). The average bluegill yield under the f-d program was 71.6 kg per hectare (63.9 pounds per acre), higher than the catch in any other period. 11 .—The average index of condition of largemouth bass in the f-d period was slightly below normal. Average bluegill condition was "fat" in June of all f-d years except 1965 and 1969. Usually the average bluegill index of condition was lower in July and August, which followed a previously observed condition cycle for that species. The condition of bluegills in 1954-1955 with fall drawdowns, but without supplemental feeding, was "fat" in June of 1954 but only reached "high average" plumpness for July and August of 1954 and for all of the summer of 1955. 12.—Largemouth bass growth was slower during the f-d period than during the period of biennial lake draining and culling of the fish population. Bluegills grew somewhat faster during the f-d period than they did during the program of drawdowns without feeding. They appeared to live longer during the f-d period and therefore attained larger sizes. They grew much faster under the f-d program than they did when water levels were stable. 13.—The pelleted food for the f-d program cost about 12 cents per acre per day, or about $11.25-$12.19 per acre per season. Fishermen were enthusiastic about the program because they were able to catch larger and fatter bluegills, and they believed that the pelleted food improved the flavor of these fish. Feeding bluegills without fall drawdowns would probably be wasteful because the bluegill population would expand faster than the food supply.published or submitted for publicationis peer reviewe

Largemouth Bass and Other Fishes in Ridge Lake, Illinois, 1941-1963

Ridge Lake was stocked with 335 yearling largemouth bass and 100 adults in 1941, 129 bluegills in 1944, 138 warmouths in 1949, and varying numbers of channel catfish in 1951, 1952, and 1957. After an attempt to remove all bluegills by draining the lake and leaving the lake basin emptv over the winter of 1959-1960, 585 lake chubsuckers and 4,500 hybrid sunfishes were stocked in the spring of 1960. Since the beginning of this study in 1941, 29,700 largemouth bass, 390.000 bluegills, and about 10,000 warmouths have been permanently removed from the lake. The lake now (1968) contains adequate numbers of all species stocked except channel catfish, which did not reproduce successfully in standing water. A complete creel census has been conducted at Ridge Lake each summer except in 1941 and 1943, when the lake was closed to public fishing. In addition, the lake was drained and the fishes were censused in the springs of 1943, 1945, 1947, 1949, 1951, 1953, 1956, 1959 (fall), and 1963, and selected kinds, sizes, and numbers of fish were held alive and restocked (Tables 1-4). One of the more important aspects of the Ridge Lake study is that, because it is a long-term investigation, it demonstrates the variability of a fairly simple population of common fishes, not only in numbers and total weight, but also in the yield obtainable from angling.published or submitted for publicationis peer reviewe

HST/ACS Emission Line Imaging of Low Redshift 3CR Radio Galaxies I: The Data

We present 19 nearby (z<0.3) 3CR radio galaxies imaged at low- and high-excitation as part of a Cycle 15 Hubble Space Telescope snapshot survey with the Advanced Camera for Surveys. These images consist of exposures of the H-alpha (6563 \AA, plus [NII] contamination) and [OIII] 5007 \AA emission lines using narrow-band linear ramp filters adjusted according to the redshift of the target. To facilitate continuum subtraction, a single-pointing 60 s line-free exposure was taken with a medium-band filter appropriate for the target's redshift. We discuss the steps taken to reduce these images independently of the automated recalibration pipeline so as to use more recent ACS flat-field data as well as to better reject cosmic rays. We describe the method used to produce continuum-free (pure line-emission) images, and present these images along with qualitative descriptions of the narrow-line region morphologies we observe. We present H-alpha+[NII] and [OIII] line fluxes from aperture photometry, finding the values to fall expectedly on the redshift-luminosity trend from a past HST/WFPC2 emission line study of a larger, generally higher redshift subset of the 3CR. We also find expected trends between emission line luminosity and total radio power, as well as a positive correlation between the size of the emission line region and redshift. We discuss the associated interpretation of these results, and conclude with a summary of future work enabled by this dataset.Comment: 18 pages, 12 figures, accepted for publication in ApJ
