Survey Of Leased Oyster Grounds Adjacent To The James River Bridge At Newport News, Virginia, Dexter Haven, Paul Kendall

Reports

This report describes the condition of leased oyster' grounds in the area which is adjacent to the proposed construction site of the second James River Bridge. This survey was accomplished by taking numerous samples of the bottom with the aid of patent tongs and counting numbers of living oysters and hard clams. The quantity of shells taken.was noted and observations were made on the nature of the· bottom. During this study, which extended frorri 31 July to 11 August, 1972, nine individual tracts of leased bottom were investigated, and ~222 samples of the bottom were collected (Table 1).

Feasibility Of Increasing Striped Bass Populations By Stocking Of Underutilized Nursery Grounds : Annual Progress Report 1971-1972, John V. Merriner, Walter J. Hogman

Reports

Numerous estuaries in the lower Chesapeake Bay region and coastal Virginia possess physical, chemical and biological properties favorable· to their use as nursery grounds for striped bass. Many of them, however, are not so utilized because of the absence of associated spawning grounds. This project was designed to investigate the feasibility of stocking such underutilized nursery grounds as a management device, while monitoring population parameters such as age composition, mortality rates and relative abundance of year classes .

The Active Pound Net Fishery In Virginia 1959-1972, Woodrow L. Wilson, Jackson W. Davis

Reports

An aerial survey of pound nets was conducted in the lower Chesapeake Bay and Virginia rivers from 1959 through 1972. The Potomac River was included from 1965 through 1972. Surveys were conducted monthly, excluding January, during this period.

The pound net is one of the most important fishing gears operated in Virginia waters. A brief description of the net is given. The number of pound nets in the fishery fluctuated from 1959 to 1966, but has been steadily declining since 1966. The term "active pound net" refers to a stand that has net hanging, and actively fishing at the time …

Biology And Utilization Of Anadromous Alosids: Annual Progress Report (October 1, 1971 - September 30, 1972), Jackson Davis, Walter J. Hoagman, John V. Merriner, Richard A. St. Pierre, Woodrow L. Wilson

Reports

Fishing effort for herring and shad has been stable for the past three years in the lower Chesapeake Bay and tributaries. River herring catch in 1972 was slightly above the 1971 landings but continued to be very low.

River herring landings in U.S. waters have declined as the c.atch has been increased by non-nationals. The catch per unit of effort has decreased from 122.5 in 1965 to 30.3 in 1972 in Virginia waters. Total mortality rates for river herring were without significant trend from 1965-1971.

Twice as much towing effort was expended in 1972 as in other years. The abundance …
