Food Of Largemouth Bass (Micropterus Salmoides) In Degray Reservoir, Arkansas, 1976, Horace E. Bryant, Thomas E. Moen Jan 1980

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 Jan 1980

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 …

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.

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 …

Status Of The Red-Cockaded Woodpecker At The Felsenthal National Wildlife Refuge In Arkansas, Douglas A. James, Fred L. Burnside Jr. Jan 1979

Status Of The Red-Cockaded Woodpecker At The Felsenthal National Wildlife Refuge In Arkansas, Douglas A. James, Fred L. Burnside Jr.

Journal of the Arkansas Academy of Science

The Red-cockaded Woodpecker is an endangered species that is endemic to mature pine forests of the southeastern United States. In Arkansas it presently occurs only in pinelands of the Ouachita Province and Gulf Coastal Plain. Cavity trees for nesting and roosting must be mature pines diseased with red-heart fungus. Due to recent forestry practices mature pine stands are disappearing thus reducing numbers of needed cavity trees. The Felsenthal National Wildlife Refuge in southeastern Arkansas contains high densities of Red-cockaded Woodpeckers and because of favorable management priorities there the survival of the woodpecker seems assured. Populations of the species in other …

Hematology As Related To Diving Characteristics Of Elaphe Obsoleta, Nerodia Erythrogaster, Nerodia Fasciata And Nerodia Rhombifera, Dennis A. Baeyens, M. W. Patterson, Chris T. Mcallister

Journal of the Arkansas Academy of Science

The diving capabilities of Nerodia erythrogaster flavigaster and Nerodia fasciata confluens were investigated and the results were compared with similar studies on Nerodia rhombifera rhombifera and Elaphe obsoleta obsoleta (Baeyens et al., 1978). In addition, morphological and hematological parameters contributing to underwater survival were examined. The duration of underwater survival for N. erythrogaster and N. fasciata was approximately one hour with no difference between the species. The lung volumes of the two species were also similar but were significantly less than lung volumes reported for E. obsoleta. There were no significant differences in hemoglobin concentration, red blood cell count or …

Abundance, Diversity And Distribution Of Benthic Macro-Invertebrates In The Flat Bayou Drainage Area, Jefferson County, Arkansas, John D. Rickett

Journal of the Arkansas Academy of Science

The main ditch of Flat Bayou Drainage in north central Jefferson County carries water southward into Plum Bayou which then shortly empties into the Arkansas River. Flat Bayou proper flows northward into Wabbaseka Bayou which in turn flows into the Arkansas River in northeastern Lincoln County. Two sites on the main ditch were sampled for physico-chemical parameters and benthic macroin vertebrates on 9 September, 7 October and 11 November 1978. No visible detrimental effects were attributed to physico-chemical characteristics. Thirty-one below-family taxa and 19 families were found in abundance from zero at one site and date to 3580 per m² …

Range And Status Of The Nutria, Myocastor Coypus, In Arkansas, Joe W. Bailey, Gary A. Heidt Jan 1978

Range And Status Of The Nutria, Myocastor Coypus, In Arkansas, Joe W. Bailey, Gary A. Heidt

Journal of the Arkansas Academy of Science

An extensive survey has shown that the current range of the nutria, Myocastor coypus. in Arkansas should include the West Gulf Coastal Plain, the Mississippi Alluvial Plain (to Missouri) and the Arkansas Valley along the Arkansas River to Oklahoma. The extensive river and creek systems in the state have provided ready avenues for dispersal, allowing for extremely rapid expansion from the early 1960's when nutria were first observed in the southern part of the state. The current range probably represents most of the suitable habitat in the state and it is felt that further expansion will be held to a …
