York River Slack Water Data Report : Temperature, Salinity, Dissolved Oxygen, 1971 - 1980, T. J. Brooks

Reports

The slack water survey program, provides an extended series of temperature, salinity, dissolved oxygen and nutrient measurements along the York River. These have been used to:

1) calibrate, verify, and update mathematical models; 2) provide a baseline against which effects of unusual events have been measured; and could be used to: 3) establish annual and longer period "climatological" trends in response to changing natural phenomena and man-made modifications to the estuary; 4) provide a basis against which fluctuations in biota could be compared.

This report contains station locations, survey schedules, field procedures, sample handling procedures, and data reduction and storage …

Bibliography Of The Monogenetic Trematode Literature Of The World, 1758 To 1982, William J. Hargis Jr., Dennis A. Thoney

Reports

Interest in the monogenean parasites has grown markedly in the last twenty years. To enhance and speed world-wide research activity, we prepared the first edition of this bibliography in 1969. This latest effort is intended to do the same.

Dorsal And Anal Pterygiophore Interdigitation Patterns In Four Species Of Morone (Teleostei, Percichthyidae) : An Aid To Larval Identification, John E. Olney, George C. Grant, Fred E. Schultz, C. Laurence Cooper, John Hageman

Reports

The diagnostic potential of dorsal and anal pterygiophore interdigitation patterns was examined in larval stages of Morone saxatilis, M. chrysops, M. americana and M.mississippiensis. The number and position of pterygiophores relative to interneural spaces 1-6 and 10-13 and interhaemal spaces 12-15 as well as total number of dorsal and anal pterygiophores are characters useful in delimiting larvae of American Morone species. Interdigitation patterns useful in separating M. mississippiensis and M. americana larvae were not found, however these two species may not co-occur.

Price Flexibility Analysis Of Virginia Hard Clams: Economic Considerations For Management Of The Fishery, Andre C. Kvaternik, William D. Dupaul, Thomas J. Murray

Reports

Price flexibility coefficients estimated for ex-vessel prices of Virginia hard clams indicate a very small (4.292 x 10-6 to 6.994 x 10-6%) decrease in price would occur given a 1% increase in the quantity supplied by Virginia harvesters. Data used were monthly landings of Virginia, New York, New Jersey, Rhode Island, Maryland and North Carolina over the period 1960-1979. Fifty-eight percent of the ex-vessel price changes are not explained by the supply response model used, suggesting other market and consumer demand factors play a large role in determining ex-vessel price. This conclusion is reached considering the historical range of production …

Lower Bay Zooplankton Monitoring Program : The August 1978 Survey, George C. Grant, John E. Olney

Reports

Monitoring of the lower Chesapeake Bay zooplankton populations was begun in March 1978 to provide a data base needed as a prerequisite to future evaluations of faunal change. An initial report (Grant and Olney, 1979) presented the basic design and sampling techniques of the Lower Bay Zooplankton Program (LBZMP), along with results of the first winter-spring cruise.

These surveys are conducted during four months of the year, with complete taxonomic analysis in March and August and analyses limited to meroplanktonic fish eggs and larvae and decapod crustacean larvae tn June and July. The present report includes results of the summer …
