The Food Habits Of Ictalurus Natalis, Centrarchus Macropterus And Perca Flavescens In Lake Drummond In The Dismal Swamp Of Virginia, Steven C. Russell Oct 1976

The Food Habits Of Ictalurus Natalis, Centrarchus Macropterus And Perca Flavescens In Lake Drummond In The Dismal Swamp Of Virginia, Steven C. Russell

Biological Sciences Theses & Dissertations

The food habits of yellow bullhead catfish (Ictalurus natalis), yellow perch (Perea flavescens), and fliers (Centrarchus macropterus) in Lake Drummond in the Dismal Swamp were examined. Seventy yellow bullheads (42 mm to 255 mm), 136 yellow perch (41 mm to 280 mm), and 110 fliers (81 mm to 140 mm), were collected with gill nets, traps, seins, and electro-fishing gear from June through November of 1975. Frequency of occurrence and volumentric data were used to evaluate the relative importance of food items. Spearman's rank correlation coef­ficient was determined from the data to test differences …

Terrestrial Ecology Of The Dickey-Lincoln School Lakes Project, Corps Of Engineers, New England Division, Environmental Research & Technology, Inc

Dickey-Lincoln School Lakes Project

This introduction of the St. John River watershed is situated in a transitional zone between the Boreal Forest Formation and the Eastern Deciduous Forest Formation. Second-growth forests representative of these two ecosystems cover extensive areas of the project site. The boreal forest forms a broad transcontinental belt in northern North America and Eurasia, with southern montane extensions. This northern forest is characterized by evergreen, coniferous trees, predominately spruce-fir The eastern deciduous forest, composed of broad-leaved hardwoods, extends throughout the eastern United States except Florida (Dasmann, 1968; Oosting, 1956).

And Quebec, Canada : Design Memorandum No. 2 : Hydrology And Hydraulic Analysis, Section Iv - Lincoln School Dam-Spillway Design Flood, Department Of The Army, New England Division, Corps Of Engineers

Dickey-Lincoln School Lakes Project

The first of four sections comprising Design Memo-randum No. 2. The other sections are: II - Dickey Dam - Spillway Design Flood, III - Lincoln School Dam - Spillway Design Flood and IV - Flood Analysis and Reservoir Regulation. la section I, hydro-logic studies will be confined generally to the drainage area of the Saint John River above the gaging station at Fort Kent, Maine. The purpose of section I is to present the climatological and streamflow data for the Saint John River above Fort Kent in order to establish hydrologic criteria for the design of the Dickey and Lincoln …


Fishes Of The Cane Creek Watershed In Southeast Missouri And Northeast Arkansas, Bruce E. Yeager, John K. Beadles Jan 1976

Fishes Of The Cane Creek Watershed In Southeast Missouri And Northeast Arkansas, Bruce E. Yeager, John K. Beadles

Journal of the Arkansas Academy of Science

A survey of the fishes of Cane Creek in southeast Missouri and northeast Arkansas was made between 25 August 1974 and 16 July 1975. Field collections, literature records, fisherman reports, and museum specimens showed the fishes of Cane Creek to be composed of 90 species distributed among 20 families. Records of Lampetra aepyptera (Abbott), Hiodon alosoides (Rafinesque), Etheostoma histrio Jordan and Gilbert, and Percina uranidea (Jordan and Gilbert) were either the first records of these species in this stream or reaffirmed their presence. The fish collected were common to the Ozark, Ozark lowland, lowland, and wide-ranging faunal groups of Pflieger …


Fishes Of The Fourche River In Northcentral Arkansas, Steve M. Bounds, John K. Beadles Jan 1976

Fishes Of The Fourche River In Northcentral Arkansas, Steve M. Bounds, John K. Beadles

Journal of the Arkansas Academy of Science

A survey of the fishes of Fourche River in northcentral Arkansas was made between June 1974 and March 1976. Field collections and literature records revealed that the river system was inhabited by 94 species of fish representing 21 families. The collected fishes represent both the Ozark and the lowland faunal groups. Fourteen species of Etheostoma and four species of Percina were collected. The records of Etheostoma asprigene and Elassoma zonatum represent extensions of the previously known ranges of these species within the state. Noturus gyrinus and Etheostoma histrio were recorded from the Black River system in Arkansas for the first …


Macrobenthos Population Changes In Crystal Lake, Arkansas, Subsequent To Cage Culture Fish, James C. Adams, Raj V. Kilambi, William A. Wickizer, Arthur V. Brown Jan 1976

Macrobenthos Population Changes In Crystal Lake, Arkansas, Subsequent To Cage Culture Fish, James C. Adams, Raj V. Kilambi, William A. Wickizer, Arthur V. Brown

Journal of the Arkansas Academy of Science

A three-year study was conducted to determine the possible effects of cage culture of fish on the environment of Crystal Lake, Arkansas. The investigation consisted of three periods: pre- (November 1971-October 1972), during- (November 1972-October 1973), and post- (November 1973-October 1974) cage culture. Numbers and biomass of benthos per square meter for pre-, during-, and post-culture periods were 1353 (10.0g), 730 (8.8g), and 1028 (4.1g), respectively. Numerically, Chaoborus sp., Chironomidae, and Oligochaeta comprised more than 97%. Chaoborus was the most numerous organism before fish culture (>68%), but dominance shifted to the Oligochaeta (>58%) after culture.
