Growth Increments And Condition Factors Of Pomoxis Annularis (White Crappie) In The Years Following Completion Of The Pump Storage Reservoir At Lake Charleston, Charleston, Il, 1982-1988, Herbert Clinton Fairow

Masters Theses

The purpose of this study was to attempt to document any changes that may have occured due to the construction of a pump storage reservoir at Lake Charleston. The age I white crappie present in the new reservoir were observed to exhibit an increase in first year growth in 1982. This increase was observed in subsequent years but not to the same degree as was observed initially. The age II fish present in the new reservoir in 1982 exhibited a very large increase in growth for the first year of the new impoundment. In the years after 1982 the annual …

Avoidance Learning And Memory In Largemouth Bass (Micropterus Salmoides) Fed Bufo Tadpoles, Randy John Gawlik

Masters Theses

Tadpoles of the American toad (Bufo americanus) have been shown to be distasteful to largemouth bass (Micropterus salmoides) predators who learn, on the short term, to avoid them. How long bass retain this learned avoidance of Bufo larvae is unknown so an experimental design was constructed in an attempt to answer this question.

Largemouth bass were divided into four treatment groups. Two groups were initially fed exclusively larvae of Bufo americanus (one group was fed large tadpoles, the other group fed small larvae). Similarily, the other two groups were initially fed spring peeper (Hyla crucifer …

A Comparison Of The Temporal Spawning Distributions And Growth Rates Of Young-Of-The-Year Redear Sunfish (Lepomis Microlophus) And Bluegill (Lepomis Macrochirus) In Three Illinois Impoundments, Craig Douglas Schmittler

Masters Theses

The purpose of this study was to compare the temporal spawning distribution and growth rates of bluegill (Lepomis macrochirus) and redear sunfish (Lepomis microlophus) in Illinois impoundments. Otolith sagittae were used to age the fish and to determine the intervals of successful spawning for both species.

Readear sunfish initiated spawning slightly before or a the same time as bluegill; however, bluegill spawned for twice as long as redear sunfish in all study impoundments. The earliest spawned fish of both species showed the fastest growth and the earliest spawned redear sunfish grew faster than did the earliest …

Observed Changes In The Largemouth Bass Population Since Construction Of A New Pump Storage Reservoir At Charleston, Illinois, Lawrence B. Durham

Masters Theses

Lake Charleston, Illinois was electrofished to determine the status of the largemouth bass (Micropterus salmoides, Lacepede) population after its reconstruction into a pump storage reservoir. The changes observed were an increased rate of growth of the initial year class, increased average growth increment of older bass, and a more abundant bass population. Factors which may have influenced increased growth were decreased turbidity, alkalinity, and increased water level. There is a possibility the increase in water level led to an increase in terrestrial invertebrates as a food source, and increased spawning substrate and cover due to submerged terrestrial vegetation. …

Daily Growth Increments In The Otoliths Of Young-Of-The-Year Largemouth Bass, Micropterus Salmoides, Steven J. Miller

Masters Theses

Daily rings were found to occur in the otoliths of laboratory-reared, young-of-the-year largemouth bass, Micropterus salmoides, for at least 151 days after swimup. Ring formation began at hatching but the total complement of prolarval rings was visible for only 10-15 days after swimup. Subdaily rings were visible in the posterior field but were easily distinguished from daily rings. Both high and low contrast tissue was present in otoliths from fish over 45 days old. Sagittal sections were superior to frontal sections for aging bass. The accuracy of the two-sections was similiar but sagittal sections were much easier and faster …

Annual Marks In The Sagittae Otoliths Of The Bluegill And Their Use In Age Determination In A Thermally Perturbed Environment, William D. Kraus

Masters Theses

This investigation was undertaken to determine if annual marks were present in the otoliths of the Bluegill sunfish, Lepomis macrochirus, and to explore their possible use as ageing structures in a thermally perturbed environment.

Two populations were studied; one from a farm pond with marked seasonal changes and the other from Lake Sanchris which serves as a cooling reservoir in central Illinois. Age determinations were made on 53 and 45 fish from the farm pond and Lake Sanchris respectively.

Annual marks were found to occur in the sagittae otoliths of the bluegill. These marks showed bright amber in sectioned …

Correlation Of Hook-And-Line Vulnerability Of Largemouth Bass (Micropterus Salmoides) With Selected Physicochemical Parameters At Ridge Lake, Dale P. Burkett

Masters Theses

Fluctuation in kilograms of largemouth bass caught per man-hour of fishing pressure (catch rate) in Ridge Lake (a 6.8ha impoundment located in Fox Ridge State Park, Coles County, Illinois) was positively correlated with dissolved oxygen concentration (r=0.7490), conductivity (r=0.7439), pH (r=0.5965), and alkalinity (r=0.7531). Negative correlations were found between largemouth bass catch rate and turbidity (r=-0.5145), as well as ammonia (r=-0.4694). No significant (p<0.05) correlations were found between catch rate and column water temperature, air temperature, barometric pressure, water level, maximum water temperature, minimum water temperature, maximum air temperature, or minimum air temperature.

Models describing the relationships of the most significant physicochemical parameters to catch rate of largemouth bass were chosen to represent the effects of environment …

Repopulation Of Fishes In Riley Creek, Coles County, Illinois Following Nitrogen Fertilizer Pollution, Kim James Carney

Masters Theses

The repopulation of stream fishes was studied from 17 May 1979 to 25 October 1979 following a major kill (100% mortality) caused by nitrogen fertilizer pollution in Riley Creek, Coles County, Illinois. The extent of recovery was determined by comparing post-kill collections with pre-kill survey data that was collected on 25 October 1978.

Repopulation began six days after the abatement of the pollution source. It is suggested that the initial source of repopulation was from the nearest undamaged tributary. The first three reinhabitants in order of appearence were: stonerollers (Campostoma anomalum); creek chubs (Semotilus atromaculatus); and …

The Effects Of Fin Clipping And Tagging On Growth And Behavior Of The Largemouth Bass (Micropterus Salmoides), Daniel M. Daley

Masters Theses

One hundred largemouth bass, ranging in size from 148mm to 385mm, were equally divided into four treatment groups (control, tag only, tag and left pectoral fin clip, and tag and all paired fins clipped) , and placed into a 5.56 hectare pond on 22 May and 25 May 1979. Upon recovery on 28 September 1979, the increase in length from the time of most recent annulus formation was found to be significantly greater in Age I control fish (x̄ = 125mm) than in fish of the same age in the other three treatment groups (x̄ = 110mm, 103mm, and 106mm, …

The Ecology Of Invertebrate Drift And Feeding Chronology Of The Striped Shiner, Notropis Chrysocephalus (Rafinesque) In Polecat Creek, Illinois, Dennis L. Newman

Masters Theses

The downstream drift of macroinvertebrates and the daily feeding cycle of the striped shiner, Notropis chrysocephalus (Rafinesque), were studied during the spring and summer of 1978 in Polecat Creek, Illinois. The purpose of the study was to: investigate the drift phenomenon of an entire lotic community, determine the pattern of diel periodicity for several important benthic populations, make qualitative and quantitative assessments of the relation of drift to benthos, and examine drift in relation to the daily feeding ecology of a cyprinid carnivore.

Polecat Creek at the sampling site was a relatively fast-flowing third-order stream, with frequent riffles. Drift sampling …

Food Habits Of The Steelcolor Shiner, Notropis Whipplei (Girard), Mark A. Dyer

Masters Theses

Specimens of the steelcolor shiner, Notropis whipplei (Girard) were seined at irregular intervals from Polecat Creek (Coles County, Illinois) from October 1974 to September 1975. Drift and benthic samples were taken in conjunction with fish collections. The stomach contents of the fish were analyzed and compared to organisms found in the drift and benthos. More food taxa were represented in the fish collected during the summer. Aquatic insect forms, primarily chironomid larvae, amounted to 75.6% of the total percentage of foods eaten during the winter as compared to 18.8% for the summer. Adult insects, mainly coleopterans and dipterans, were the …

Parasites Of Channel Catfish In Illinois Hatcheries, Charles Dale Meryman

Masters Theses

Ninety channel catfish (Ictalurus punctatus) were trapped during September 1973 through April 1974 at three hatcheries located at Worden, Centralia, and Kinmundy, Illinois. All were examined for parasites and 87 were parasitized. The trematodes Azygia angusticauda and Neascus sp. were found in the gastrointestinal system and Cleidodiscus floridanus and Dactylogyrus sp. were attached to the gills. Five cestode genera, including Bothriocephalus sp., Corallobothrium giganteum, Eubothrium sp., Haplobothrium sp., and Proteocephalus ambloplitis were present. Rhabdochona sp. was the only nematode found. Protozoans; Costia sp., Myxobolus sp., Scyphidia macropodia and Trichodina discoidea and one kind of glochidium were observed. …

Rate Of Growth As A Method Of Assessing Water Quality, George L. Johnston

Masters Theses

A study of the Embarras River basin was conducted to determine if rate of growth could be used as an indicator of water quality. Six species of sucker were collected from five locations using hand seines and electrofishing gear from December 1970 to December 1971. Tests of eighteen water quality parameters were conducted from November 1970 to November 1971.

The fish were measured and scale samples taken. The rate of growth of the fish taken at the five stations was analyzed and compared using the single classification analysis of variance. Condition factors were also compared.

Although there was some difference …

The Effect Of Thermal Increases On The Acute Toxicity Of Copper And Hexavalent Chromium To Channel Catfish (Ictalurus Punctatus), Alan Kirk Millis

Masters Theses

48-hr, 96-hr, and incipient median tolerance limits of channel catfish (Ictalurus punctatus Rafinesque) to copper and hexavalent chromium were determined at temperatures of 50, 60, 70, and 80 F. Standard static bioassay procedures were used. The incipient TLm for copper ranged from 0.56 ppm to 2.15 ppm and from 22.5 to 39.5 ppm for hexavalent chromium. The 48-hr and 96-hr results were somewhat higher. The highest resistance for both metals occurred at 70 F. At 80 F, however, there was a sharp decrease in tolerance. Increased oxygen consumption and opercular movement offer a possible explanation since they would …

A Study Of Organochlorine Insecticides In Freshwater Crayfish -- Analytical Problems And Biomonitoring Survey, Robert C. Vanderjack

Masters Theses

Crayfish were collected from 3 sites on Polecat Creek, Coles County, Illinois in early spring, early summer, and late summer of 1972. Pesticides were extracted from the crayfish tissue in a one step procedure utilizing a Florisil elution column. Analysis was by electron capture gas chromatography. Pesticide residues in the nannogram range were analyzed and background contamination was an important consideration. Sources of background contamination were investigated and teflon stopcocks, Florisil, and residues on “cleaned” glassware were found to be major contamination sources. Distilled water used in flushing glassware should also be considered a potential contamination source.

Parasites From Gizzard Shad, Dorosoma Cepedianum, In Lake Charleston, Illinois, Francis M. Yabai Kaikumba

Masters Theses

Eighty gizzard shad (Dorosoma cepedianum) from Lake Charleston, Charleston, Illinois were examined for parasites. Eight fish were parasitized. Three fish contained the acanthocephalan Tanaorhamphus longirostris, three fish harbored cestodes of the genus Glaridacris and two fish had the nematode Camallanus oxycephalus. The latter is here reported for the first time from gizzard shad. Twenty fish were infected with the fungus Saprolegnia sp. The numbers of helminth parasites harbored by shad are less than reported for other forage fish. However, the incident of parasitism reported in this study is greater than that reported by previous workers.

Nutrition Studies Of The Brindled Madtom, Noturus Miurus Jordan, Based On Stomach Content Analysis, Randall Stephen Madding
