Interrelationships Between Benthic Macroinvertebrates And Habitat In A Mountain Stream, John M. Payne
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A study to determine habitat differences of benthic macroinvertebrates was conducted on the upper Strawberry River, Utah. The investigation was part of a large scale project to determine minimum stream flow requirements for trout. The effects of time, habitat, depth and velocity on the distribution of benthic fauna were evaluated.
Samples of benthic invertebrates (146 total) were collected every 2 months at 8 stations on the river from November, 1975 through August, 1976. Representatives of 59 taxa were collected. Eight taxa comprised 90 percent of the mean annual community standing crop in numbers. Biomass was not dominated by any group …

A Study Of Oyster Ground Leases Adjacent To The James River Bridge, Newport News, Virginia, Dexter S. Haven, Paul C. Kendall
A Study Of Oyster Ground Leases Adjacent To The James River Bridge, Newport News, Virginia, Dexter S. Haven, Paul C. Kendall
Reports
Two leases of oyster planting ground adjacent to the James River Bridge at the Newport News end were studied in December, 1978. Sampling revealed that one area contained large quantities of oysters while, on the other area, oysters were scarce. Comparison with sample results and fathometer-traced bottom profiles taken in a 1976 study of the same areas indicates a close similarity.

Kepone® Residues In Chesapeake Bay Biota, M. E. Bender, R. J. Huggett, W. J. Hargis Jr.
VIMS Books and Book Chapters
Oysters from the James displayed variations in Kepone residue levels related to water temperature and their spawning cycle. Oyster depuralion rates were related to temperature. In summer the "biological half. life" of Kepone in oysters was about one week, while during the winter about 40 days were required for residue levels to decline by 50 per cent. Residues in blue crabs varied as a function of sex, males having considerably higher residues than females. Fin fish levels from the James varied greatly, with residue levels being dependent on species and length of residence for migratory fishes .. Average Kepone residues …
Coliform Depuration Of Chesapeake Bay Oysters, Dexter S. Haven, Frank O. Perkins, Reinaldo Morales-Alamo, Martha W. Rhodes
Coliform Depuration Of Chesapeake Bay Oysters, Dexter S. Haven, Frank O. Perkins, Reinaldo Morales-Alamo, Martha W. Rhodes
VIMS Books and Book Chapters
Oysters contaminated in nature depurated fecal coliforms to levels below 50/100 g in 48 hr over a wide range of environmental conditions typical of the lower Chesapeake Bay region. Temperature was found to be the most crilical environmental factor with conditions below 10-12°C having the potential of inhibiting depuration. Coliform clearance did not appear to be correlated with pumping rate or biodeposition activity of oysters. Oysters infected with the pathogens Dermocystidium marinum and Minchinia nelsoni (MSX) depurated as rapidly as uninfected ones. Meat quality and size of oysters likewise did not affect depuration.
Four commercial-size tanks of different designs were …

Potential Use Of Hydroelectric Facilities For Manipulating The Fertility Of Lake Mead, Larry J. Paulson, John R. Baker, James E. Deacon
Potential Use Of Hydroelectric Facilities For Manipulating The Fertility Of Lake Mead, Larry J. Paulson, John R. Baker, James E. Deacon
Publications (WR)
Analysis of historical nutrient data for Lake Mead indicates that the fertility of the reservoir has decreased which may be the cause for a corresponding decline in the largemouth bass population. However, it appears that fertility can be manipulated by altering the operation of the dam. The depletion of nutrients in the euphotic zone by phytoplankton and subsequent accumulation in the hypolimnion during summer and fall provide a natural nutrient gradient from which water of varying fertility can be drawn for discharge. This combined with alterations in the depth or seasonal pattern of discharge can possibly be used to enhance …

The Life History And Ecology Of Ptilostomis Postica (Walker) (Trichoptera: Phryganeidae) In Greenbottom Swamp, Cabell County, West Virginia, Mary Beth Roush
Theses, Dissertations and Capstones
The life histoy and ecology of Ptilostomis postica (Walker) from Greenbottom swamp in Cabell County, West Virginia were investigated from December 1977 to December 1978, Length-frequency histograms indicate the life cycle is uriivoltine. Larvae achieved their greatest growth rate (75%) from fall to winter. Case length showed its greatest increase (70.3%) for this same period. There was high correlation between case length and body length in fall (r=0.72) and winter (r=0.87), however, a low correlation (r=0.18) was found in spring. The diet of the larvae changed from carnivorous in fall and winter to omnivorous in spring. Pupation began at the …

Proposed Environmental Impacts Of The Gallipolis Locks And Dam Replacement, Ohio River Mile 279.2, On The Benthic Macroinvertebrates And Fishes Of Flatfoot Creek, Mason County, West Virginia, William L. Cremeans Jr.
Theses, Dissertations and Capstones
The Gallipolis Locks and Dam at Ohio River Mile 279.2 is soon to be modified or replaced. Construction in the area will effect the lower portion of the small drainage basin (14.61 km) of Flatfoot Creek. Depending on the action taken, a large proportion of Flatfoot Creek and/or a tributary of Mud Run will have severe ecological alterations. For this reason, Flatfoot Creek was investigated for water quality, benthic macroinvertebrates, fish populations and the feeding requirements of the fishes.
A physio-chemical analysis was made of Flatfoot creek. With the exception of five parameters, the creek met guidelines set by state …

Oyster Spatfall On Shellstrings In Virginia Rivers: 1978 Annual Summary, Dexter S. Haven, Paul C. Kendall
Reports
The Virginia Institute of Marine Science (VIMS) conducts weekly surveys from June through early October to obtain oyster spatfall information. Spat counts are made from oyster shells strung on wire and suspended from stakes on public and private beds. The number of spat on shells are counted each week of the spawning season to determine the potential of a particular area for receiving a strike and to predict the most likely period the strikes will occur. Shells planted just before the period of maximum set have the best chance of getting a good strike.
Feeding Studies On Three Species Of Fish From Tomales Bay, California, John Brezina
Feeding Studies On Three Species Of Fish From Tomales Bay, California, John Brezina
University of the Pacific Theses and Dissertations
The study of fish diets or feeding behavior is an important aspect in ecology. Analysis of fish stomach contents often provides data for determining resource utilization, feeding strategies, and overlaps in food items among and between species. Studies of fish diets could also be used for testing ecological theory or provide management procedures for fisheries if methods could be developed for minimizing competitive food utilizations by other fish and enhancing growth of exloited fish populations (Obrebski and Sibert 1977). In order to understand more about ecological communities and competitive predatory relationships of fish, more data are required on their diets …
