Systematic Status Of The Fishes Of Genus Campostoma (Cyprinidae) Inhabiting The Major Drainages Of Northern Arkansas, Stephen A. Sewell, John K. Beadles, V. Rick Mcdaniel
Journal of the Arkansas Academy of Science
A total of 6980 morphometric and meristic data points were analyzed from specimens previously identified as Campostoma anomalum pullum and Compostoma oligolepis from all areas of their Ozark ranges in Arkansas. Data were analyzed using the Statistical Analysis System (SAS) and IBM 370 Computer System (HASP II). An attempt was made to establish separation points through multivariate analysis (MANOVA) by taxon and watershed. Additional analyses included factor analysis and discriminant function analysis. Scale count frequencies were analyzed using computer program MINITAB. MANOVA revealed a lack of consistent separation points, and Ozark populations were shown to be distinct and highly variable …

Food Of Largemouth Bass (Micropterus Salmoides) In Degray Reservoir, Arkansas, 1976, Horace E. Bryant, Thomas E. Moen
Food Of Largemouth Bass (Micropterus Salmoides) In Degray Reservoir, Arkansas, 1976, Horace E. Bryant, Thomas E. Moen
Journal of the Arkansas Academy of Science
Stomach contents were examined from 748 largemouth bass, Micropterus salmoides (<125 mm total length), collected from DeGray Reservoir during April-November 1976. Fish constituted 59% by weight of the total diet and occurred in 81% of the stomachs; crayfish made up nearly 38% of the weight and occurred in 24% of the stomachs. Sunfish, the principal fish food (about 28% by weight), were observed in 36% of the stomachs. Shad were the second most important prey (23% by weight and 29% frequency in occurrence). Crayfish constituted about 42% of the total weight of the food of bass 200 mm long or longer, but only 12% in bass less than 200 mm. Crayfish consumption was greatest during the fall.
Inventory Of The Decapod Crustaceans (Crayfishes And Shrimps) Of Arkansas With A Discussion Of Their Habitats, Raymond W. Bouchard, Henry W. Robison
Inventory Of The Decapod Crustaceans (Crayfishes And Shrimps) Of Arkansas With A Discussion Of Their Habitats, Raymond W. Bouchard, Henry W. Robison
Journal of the Arkansas Academy of Science
The freshwater decapod crustaceans of Arkansas presently consist of two species of shrimps and 51 taxa of crayfishes divided into 47 species and four subspecies. The shrimps are represented by Macrobranchium ohione and Palaemonetes kadiakensis. The crayfish fauna is the largest of any state west of the Mississippi River reflecting the variety of habitats within Arkansas as a result of the geologic diversity in the state. The Ozark Plateaus and Ouachita provinces are dominated by the genus Orconectes, while in the Gulf Coastal Plain Procambarus is the most conspicuous group. Other crayfish stocks present include Cambarus, found predominantly in the …
Fishes Of Rock Creek, Sharp County, Arkansas, F. Allen Carter, John K. Beadles
Fishes Of Rock Creek, Sharp County, Arkansas, F. Allen Carter, John K. Beadles
Journal of the Arkansas Academy of Science
A survey of the fishes of Rock Creek in north central Arkansas was made on 9-10 November, 1978, and 15-16 March, 1979. Field collections were made using a minnow seine and backpack shocker. The creek system was inhabited by 28 species of fish representing eight families. Fish collections were typical of a small Ozark stream. The most abundant species were: Campostoma oligolepis Hubbs and Greene, largescale stoneroller; Notropis telescopus (Cope), telescope shiner; Notropis zonatus (Putnam), bleeding shiner; Moxostoma duquesnei (Lesueur), black redhorse; Etheostoma blennioides Rafinesque, greenside darter; Etheostoma caeruleum Storer, rainbow darter; Etheostoma euzonum (Hubbs and Black), Arkansas saddled darter; …
Recent Mollusca Of Arkansas With Annotations To Systematics And Zoogeography, Mark E. Gordon
Recent Mollusca Of Arkansas With Annotations To Systematics And Zoogeography, Mark E. Gordon
Journal of the Arkansas Academy of Science
A total of 223 taxa of Mollusca are presently known from Arkansas. The geological history and geomorphology of the region, particularly the presence of the Interior Highlands, have been responsible for the development of a diverse molluscan fauna. Thirty regionally endemic forms are included among the 107 terrestrial gastropods, 36 aquatic gastropods, 65 unionacean mussels, and 15 sphaeriacean clams.
Water Striders (Hemiptera: Gerridae) Of Arkansas, Paul D. Kittle
Water Striders (Hemiptera: Gerridae) Of Arkansas, Paul D. Kittle
Journal of the Arkansas Academy of Science
The taxonomy, distribution, and ecology of the water striders of Arkansas are discussed based on personal collections, museum specimens, and literature records. A total of 15 species representing six genera is presently known from the state. One additional species is included as probably occurring in Arkansas.
Estimated Growth And Standing Crop Of Largemouth Bass (Micropterus Salmoides) From Lake Elmdale, Alex Zdinak Jr., Raj V. Kilambi, Marvin L. Galloway, John E. Mcclanahan, Clark Duffe
Estimated Growth And Standing Crop Of Largemouth Bass (Micropterus Salmoides) From Lake Elmdale, Alex Zdinak Jr., Raj V. Kilambi, Marvin L. Galloway, John E. Mcclanahan, Clark Duffe
Journal of the Arkansas Academy of Science
Electro-fishing gear was used to make shoreline population estimates of largemouth bass (Micropterus salmoldes) in Lake Elmdale, Washington County, Arkansas, during September 1979. The population density was estimated to be 1541 bass/Km² with a standing crop of 30.4 kg/ha. The length-weight relationship was calculated as W = 0.00001 504L^2.97, and the total length-scale radius relationship as L = 41.75 + 1.23 St. The average condition coefficient(K) was 1.31. In comparison with four other Arkansas lakes the population density of largemouth bass was highest in Lake Elmdale while the growth rate was lowest.

Food Of Bluegill And Longear Sunfish In Degray Reservoir, Arkansas, 1976, Horace E. Bryant, Thomas E. Moen
Food Of Bluegill And Longear Sunfish In Degray Reservoir, Arkansas, 1976, Horace E. Bryant, Thomas E. Moen
Journal of the Arkansas Academy of Science
Stomach contents were examined from 544 bluegill (Lepomis macrochirus) and 709 longear sunfish (L. megalotis) collected from nearshore areas of DeGray Reservoir April-November 1976. Major foods of bluegill (percentage of total weight of food in parentheses) were insects (33), bryozoa (7.3), planktonic crustaceans (6.5), and plant materials (15.4). The major food items contributing to the diet of longear sunfish were insects (52.6%), crayfish (12.5%), fish (7.4%), and plant material (6.7%). Although bluegill and longear sunfish are closely related species, their diets were not as similar as expected: bluegill consumed zooplankton, adult dipterans, and adult ephemeropterans associated with limnetic areas; while …
