  • 15 Best Indiana Panfishing Lakes
    15 best Indiana panfishing lakes This information has been shared numerous places but somehow we’ve missed putting it on our own website. If you’ve been looking for a place to catch some dinner, our fisheries biologists have compiled a list of the 15 best panfishing lakes throughout Indiana. Enjoy! Northern Indiana Sylvan Lake Sylvan Lake is a 669-acre man made reservoir near Rome City. It is best known for its bluegill fishing with some reaching 9 inches. About one third of the adult bluegill population are 7 inches or larger. The best places to catch bluegill are the Cain Basin at the east end of the lake and along the 8 to 10 foot drop-offs in the western basin. Red-worms, flies, and crickets are the most effective baits. Skinner Lake Skinner Lake is a 125-acre natural lake near Albion. The lake is known for crappie fishing for both black and white crappies. Most crappies are in the 8 to 9 inch range, with some reaching 16 inches long. Don’t expect to catch lots of big crappies, but you can expect to catch plenty that are keeper-size. The best crappie fishing is in May over developing lily pads in the four corners of the lake. Live minnows and small white jigs are the most effective baits. J. C. Murphey Lake J. C. Murphey Lake is located on Willow Slough Fish and Wildlife Area in Newton County. Following this winter, there was minimal ice fishing (due to lack of ice) and the spring fishing should be phenomenal especially for bluegills.

  • Wildlife Species
    Wildlife Species This chapter contains information on species featured in each of the ecoregions. Species are grouped by Birds, Mammals, Reptiles, Amphibians, and Fish. Species are listed alphabetically within each group. A general description, habitat requirements, and possible wildlife management practices are provided for each species. Wildlife management practices for a particular species may vary among ecoregions, so not all of the wildlife management practices listed for a species may be applicable for that species in all ecoregions. Refer to the WMP charts within a particular ecoregion to determine which practices are appropriate for species included in that ecoregion. The species descriptions contain all the information needed about a particular species for the WHEP contest. However, additional reading should be encouraged for participants that want more detailed information. Field guides to North American wildlife and fish are good sources for information and pictures of the species listed. There also are many Web sites available for wildlife species identification by sight and sound. Information from this section will be used in the Wildlife Challenge at the National Invitational. Participants should be familiar with the information presented within the species accounts for those species included within the ecoregions used at the Invitational. It is important to understand that when assessing habitat for a particular wildlife species and considering various WMPs for recommendation, current conditions should be evaluated. That is, WMPs should be recommended based on the current habitat conditions within the year. Also, it is important to realize the benefit of a WMP may not be realized soon. For example, trees or shrubs planted for mast may not provide cover or bear fruit for several years.

  • Summer Panfish Survey Summary Turtle-Flambeau Flowage, Iron County, 2010
    Summer Panfish Survey Summary Turtle-Flambeau Flowage, Iron County, 2010 The Mercer DNR Fisheries Management Team conducted a fyke netting survey on the Turtle- Flambeau Flowage during June 29-30, 2010 as part of our baseline monitoring program. Nine nets were set overnight, for one night, resulting in 9 net-nights of effort. Primary target species were bluegill, black crappie, and pumpkinseed sunfish. An electrofishing survey conducted by the Mercer team in mid May documented the status of smallmouth bass (summarized in a separate survey summary) but provided a poor sample of panfish, which were not targeted specifically. We believe this netting survey provides better insight into the relative number and sizes of panfish in the Turtle-Flambeau Flowage. Quality, preferred, and memorable sizes referenced in this summary are based on standard proportions of world record lengths developed for each species by the American Fisheries Society.

  • Evaluation of Supplemental Pellet Feeding and Threadfin Shad Addition on Stable Isotope Signature and Potential Influence on Fish Growth in Recreational Fishing Ponds
    Supplemental Pellet Feeding Henderson et al. Evaluation of Supplemental Pellet Feeding and Threadfin Shad Addition on Stable Isotope Signature and Potential Influence on Fish Growth in Recreational Fishing Ponds Hugh K. Henderson1, School of Fisheries, Aquaculture, and Aquatic Sciences, Auburn University, AL 36849 Russell A. Wright, School of Fisheries, Aquaculture, and Aquatic Sciences, Auburn University, AL 36849 Dennis R. DeVries, School of Fisheries, Aquaculture, and Aquatic Sciences, Auburn University, AL 36849 Matthew J. Catalano, School of Fisheries, Aquaculture, and Aquatic Sciences, Auburn University, AL 36849 David C. Glover, U.S. Fish and Wildlife Service, Carterville Fish and Wildlife Conservation Office, 9053 Route 148, Suite A, Marion, IL 62959 Abstract: Pond enhancements such as adding pelleted feed or stocking threadfin shad (Dorosoma petenense) are sometimes used in the management of pond fisheries, but their relative impacts on growth and reproduction at multiple levels of the food web are not often fully evaluated. We used stable isotope analysis to indicate the contribution of pelleted feed to bluegill (Lepomis macrochirus) reproduction and growth, and ultimately to largemouth bass (Micropterus salmoides) growth in the presence and absence of threadfin shad via two different approaches: a pond experiment and sampling of established ponds. Bluegill growth and reproductive metrics increased with increased rates of pelleted feed provided. Bluegill nitrogen signature decreased with pelleted feed in the small pond experiment, suggesting feeding at a lower trophic level with increased feed. Largemouth bass nitrogen signature results showed similar trends to that of bluegill, although not statistically significant. In established ponds, pelleted feed appeared to alter the carbon isotopic signatures of both bluegill and largemouth bass independent of threadfin shad presence.

  • Growth Data on Sport Fishes in Twelve Lakes in Kansas FRANK B
    f Growth Data on Sport Fishes in Twelve Lakes in Kansas FRANK B. CROSS, JAMES E. DEACON, and CLAUD M. WARD This paper presents data on the growth-rates of nine kinds of game fish collected from 1952 to 1956 inclusive from twelve of the more important lakes in Kansas: Crawford County State Lake number 2 (= Farlington); Gardner Lake, Johnson County; Lone Star Lake, Douglas County; Prairie Lake, Jackson County; Leavenworth County State Lake (= Tonganoxie); Lake Wabaunsee, Wabaunsee County; Wyandotte County Lake; Herington Lake, Dickinson County; Nemaha County State Lake; Ottawa County State Lake; Cedar Bluff Reservoir, Trego County; and Kanopolis Reservoir, Ellsworth County. Fish were obtained by personnel of the State Biological Survey, especially Mr. W. J. Davis, by means of gill nets (3/4-inch to 2-inch mesh, bar measure), hoop- and fyke-nets (1-inch mesh, bar measure), and rotenone. Most fish from Lone Star Lake were collected with hook- and-line by Mr. J. S. Carey. A scale-reader similar to that described by Van Oosten, Deason, and Jobes (Jour. du Conseil 9[2] :241-248, 1934) was used to ascertain ages of the fish. The ages assigned in Table I represent the number of growing seasons completed. Total lengths at the time of capture were used for fishes that were taken from November 1 to June 1 inclusive; these fish were considered to be in an interphase between growing seasons. For fish that were caught in the period June 1 to November 1, the total length was calculated to the last annulus by direct proportion, using scale- measurements that were made when the scales were read.
