Distribution And Abundance Of Calanoid Copepods In The York River Estuary, Virginia, 1968 And 1969, Victor G. Burrell Jr.
Distribution And Abundance Of Calanoid Copepods In The York River Estuary, Virginia, 1968 And 1969, Victor G. Burrell Jr.
Dissertations, Theses, and Masters Projects
Calanoid copepods were sampled quantitatively at twelve stations in the York River estuary monthly over a two year period. Twenty-two different calanoid species were identified, with five species, Acartia tonsa, A. clausi, Eurytemora affinis, Pseudocalanus minutus and Pseudodiaptomus coronatus making up 95% of the numbers present. Several factors were investigated to determine their biological influence was the ctenophore, Mnemiopsis leidyi, a predator which reduced copepod numbers logarithmically at stations at which it occurred. Increased river flow was followed by large increases in copepod numbers and was the most important physical influence.
Distribution of all calanoid species appearing in the estuary …

This dissertation is from the Joint Program Degree from the College of William & Mary and University of Virginia and awarded by the University of Virginia.
Provisional keys to the marine decapod crustacean zoeae of the Chesapeake Bay are presented. These keys provide distinguishing characters for the specific or generic identification of zoeae of 50 decapod species. Also, provisional classification schemes for the different morphological types of antennae and telsons exhibited by Chesapeake Bay brachyuran larvae are given, and the larval stages of each species or genus considered in the keys are briefly described.
The larval development of eight Chesapeake …

Acute Toxicity Of Unbleached Kraft Mill Effluent (Ukme) To The Oppossum Shrimp, Neomysis Americana Smith, Fred Jacobs
Acute Toxicity Of Unbleached Kraft Mill Effluent (Ukme) To The Oppossum Shrimp, Neomysis Americana Smith, Fred Jacobs
Dissertations, Theses, and Masters Projects
96-hour TL50 values of unbleached kraft mill effluent (UKME) for Neornysis arnericana were found to range from concentrations of 3.29 to 6.85% at 26-28 C and 3.90 to 7.30% at 16-18 C. Differences between batches of effluent proved insignificant in experiments at each temperature regime. Furthermore, UKME did not lose its toxicity, when stored for 5 to 7 days at 4 C. A concentration of 20% effluent killed 100% of the organisms in 8 of the 12 bioassays. Slope functions and confidence limits of TL50 were calculated. This dissertation is from the Joint Program Degree from the College of William …
Distribution, Growth, Selective Feeding, And Energy Transformations Of Young-Of-The-Year Blueback Herring, Alosa Aestivalis (Mitchill), In The James River, Virginia, Richard Greig Burbidge
Distribution, Growth, Selective Feeding, And Energy Transformations Of Young-Of-The-Year Blueback Herring, Alosa Aestivalis (Mitchill), In The James River, Virginia, Richard Greig Burbidge
Dissertations, Theses, and Masters Projects
Energy transformations and budget are computers for young-of-the-year blueback herring, Alosa aestivalis, in the James River, Virginia. Distribution, growth, and selective feeding are described. Fish and zooplankton collections were made at five stations in the main channel of the James RIver from June through November 1969. Two 24hr series of samples were collected in July and October 1968 in the Potomac River. A direct relationship existed between standing cropos of zooplankton and distribution, growth, and feeding of blueback herring. Zooplankton densities were highest upstream, where food consumption and growth rates were correspondingly highest. A progressive downstream decrease and upstream increase …
The Reproductive Cycle And Larval Tolerances Of Rangia Cuneata In The James River, Virginia, Thomas David Cain
The Reproductive Cycle And Larval Tolerances Of Rangia Cuneata In The James River, Virginia, Thomas David Cain
Dissertations, Theses, and Masters Projects
The autecology of the brackish water clam Rangia cuneata was investigated in the James River, Virginia, from February 1970 to January 1972. The reproductive cycle, combined salinity and temperature effects on embryos and larvae, and setting were studied. Histological slides were made, set collected, and temperature and salinity measurements taken from three populations living in different salinity regimes. Phases of gonad development are described. Gametogenesis started in April and from May through September clams were found in all gonadal phases. Ripe gonads were found from May to late November with no summer or inactive period. It was determined by the …

Feasibility Of Artificial Propagation And Introduction Of Hybrids Of The Morone Complex Into Estuarine Environments, With A Meristic And Morphometric Description Of The Hybrids, Jerome Howard Kerby
Feasibility Of Artificial Propagation And Introduction Of Hybrids Of The Morone Complex Into Estuarine Environments, With A Meristic And Morphometric Description Of The Hybrids, Jerome Howard Kerby
Dissertations, Theses, and Masters Projects
Laboratory and environmental studies of striped bass (Morone saxatilis) X white perch (M. americana) and striped bass X white bass (M. chrysops) were used to-determine the feasibility of introducing these hybrids into an estuary as a supplement to natural populations of the parental species. Growth patterns, survival, and general hardiness of the hybrids were used as criteria. Growth of striped bass X white perch hybrids in the laboratory was apparently somewhat less than growth of natural populations of striped bass, but was much greater than growth of natural populations of white perch. Hybrid growth was slower than striped bass growth …
