Laboratory And Field Studies Of The Fauna Of The Upper James Estuary : Annual Report Submitted To Virginia Electric And Power Company, Virginia Institute Of Marine Science

Reports

Grab samples at 31 stations in the Hog Island region of the James River to evaluate the benthic fauna. All species of infauna taken were identified and weighed. Sediment particle size analysis was made at each station. This region is characterized by a low diversity. The dominant organism, Rangia cuneata, may occur in densities up to l,000/m2. Other organisms common to the area are Congeria leucophaeata, Scolecoleides viridis, Corophium lacustre, Leptocheirus plumulosus and Cyathura polita.

Laboratory studies werb made to determine the effects of temperature shock on oyster! larvae, Crassostrea virginica. 10° and 15° temperature shocks were used. Growth …

Phlyctainophora Squali Sp. Nov. (Nematoda, Philometridae) From The Spiny Dogfish, Squalis Acanthias, Dwight R. Mudry, Murray D. Dailey

Harold W. Manter Laboratory: Library Materials

Summary

Phlyctainophora squali sp. nov. is described from 23 female specimens recovered from the subcutaneous tissue of one of 440 Squalis acanthias caught off Los Angeles, California. This finding represents a new host and distribution for this genus. Phlyctainophora is placed in the family Philometridae on the basis of atrophication of vulva and anus, simple mouth, viviparity and location in tissue of fishes. The family diagnosis for Philometridae is amended to include Phlyctainophora which lacks an anterior ovary.

Treatment Of Shell Cultch With Polystream To Increase The Yield Of Seed Oysters, Crassostrea Virginica, Michael Casatagna, Dexter S. Haven, James B. Whitcomb

VIMS Articles

A commercial scale study was conducted on the Eastern Shore of Virginia during 1964, 1965 and 1966 to evaluate treatment of shell cultch with Polystream. Three intertidal reefs of the same approximate size were shelled with similar amounts of untreated shells.

The Fisheries Of Deer Creek Reservoir, Utah, With Special Emphasis On The Yellow Perch (Perca Flavescens Mitchill), Gale R. Lewellen

Theses and Dissertations

This thesis is concerned with the fisheries of Deer Creek Reservoir, Wasatch County, Utah, with special emphasis on the yellow perch. The study period was from May 13 to November 24, 1968. Objectives included the determination of size, age, and food habits of the yellow perch. Parasitic occurrences in the perch population by Ligula intestinalis were also recorded as well as the utilization of the perch by the fishermen. Observations on other species of fish including an analysis of rainbow trout stocking programs were also objectives of this thesis. Data was gathered by means of creel census and fish collection …

Meteorological Factors Controlling The Emergence Of The Eastern Spadefoot Toad, Scaphiopus Holbrooki Holbrookii Harlan, Larry Judy

Theses, Dissertations and Capstones

Scaphiopus holbrooki holbrookii, the Eastern Spadefoot, can exist in an area for many years before it is detected. Its apparent scarcity can be explained by its secretive, fossorial habitat, protective coloration, and nocturnal behavior. Spadefoots are present at the surface locally in small numbers on any one night. They emerge only when conditions are optimum. One authority has suggested that temperature, moisture, and barometric pressure exert control over emergence.

It was the purpose of this research to discover the most important meterorological parameters and investigate how they control the behavior of Scaphiopus.

Initially the response, emergence to breed was distinguished …

Treatment Of Shell With Polystream To Increase Survival Of Oysters (Crassostrea Virginica) In Virginia, Dexter S. Haven, James P. Whitcomb

Reports

Survival of oysters set on shells treated with Polystream* was investigated during 1963 and 1964. Treated and control shells were held in wire bags in the high-salinity intertidal seaside area of the Eastern Shore and in the moderate-salinity subtidal areas of the lower James River. Significantly more spat survived on treated shells than on controls. Differences in survival could not be attributed to absence of drill predation on treated shell.

Biology And Utilization Of Anadromous Alosids: Annual Progress Report (October 1, 1968 - September 30, 1969, Jackson Davis, Joseph P. Miller, J. Ernest Warriner

Reports

Estimates of average annual mortality rates were derived. from the decline in numbers of repeat river herring spawners each year. in the Rappahannock and Potomac Rivers. The 1961 year-class contributed slightly more than 6 million fish to the fishery since 1965 while the 1962 year-class contributed nearly 5 million fish. Estimates could not be made for the James and York Rivers because the catch could not be measured. Fishing effort generally declined from 1968 in all major rivers with the Potomac River exhibiting the greatest decline. The catch of river herring in 1969 was generally lower than in 1968. Shad …

Comparative Strength Of The 1966 Year Class Of Striped Bass, Roccus Saxatilis (Walbaum), In Three Virginia Rivers, George G. Grant, Edwin B. Joseph

VIMS Books and Book Chapters

The age composition, as determined from scale impressions, of striped bass stocks in the James, York, and Rappahannock Rivers during the period June 1967 - March 1968 indicates a relative deficiency of the 1966 year class in the James River. Similar results are shown in samples from non-selective gear (pound nets, fyke nets), selective gear (gill nets, haul seines, hook-and-line), and routine surveys using a 30-foot semi-balloon trawl.

On Models Of Commercial Fishing, Vernon L. Smith

Economics Faculty Articles and Research

Commercial fishing is characterized by three key economic and technological features that are relevant to the formulation of an economic theory of fish production. 1. A fishery resource, although conceivably exhaustible, is replenishable; that is, it is subject to laws of natural growth which define an environmental biotechnological constraint on the activities of the fishing industry. 2. The resource and the activity of production from it form a stock-flow relationship. The new growth in the population fish mass depends upon the harvest rate relative to natural recruitment to the stock. If the harvest rate exceeds the recruitment rate, the stock …
