Vertical One-Dimensional (1-D) Simulations Of Horizontal Velocity Profiles, Jerome P.Y. Maa, Jian Shen, Xiaoteng Shen, Shao Yuyang

Reports

Details of a vertical 1-D hydrodynamic model to simulate the horizontal velocity profiles for tidal estuarial flows with possible stratifications caused by salinity or Suspended Sediment Concentration (SSC) are presented. The standard 2nd order k-ε model was implemented to address the turbulent flow with possible stratification effects. Simulation results are verified with two field measurements for steady nonstratified flows and a field measurement for tidal estuary non-stratified flow. The stratification effect of salinity and suspended sediment concentration are also checked with the following descriptions: “Salinity stratification will change the typical logarithmic velocity profile to a linear profile for most of …

Juvenile Fish And Blue Crab Stock Assessment Program Bottom Trawl Survey Annual Data Summary Report Volume 1999, Wendy A. Lowery, M. Todd Mathes, Patrick J. Geer

Reports

This report summarizes data collected by the Virginia Institute of Marine Science (VIMS) monthly trawl survey cruises for January to December 1999. The trawl survey is a long-term, broad scope monitoring program. Its primary goal is to monitor juvenile abundance for marine and estuarine finfish and invertebrates. A major objective is to provide annual indices of juvenile abundance for recreationally, commercially, and ecologically important species of sufficient accuracy and precision for both immediate resource management needs and long-term understanding of environmental influences on fishery resources. A second important product of this effort is the documentation and monitoring of habitat utilization …

Juvenile Finfish And Blue Crab Stock Assessment Program York River Random Stratified Bottom Trawl Survey Data Summary Report Volume R1989-1990, Michael F. Land, Patrick J. Geer, Christopher F. Bonzek, Herbert M. Austin

Reports

The Virginia Institute of Marine Science (VIMS) has conducted a bottom trawl survey of some fashion since 1955. Historically, sampling has occurred as mid-channel transects at fixed locations spaced at approximately five mile intervals. In the early 1970's, work was performed on the Mobjack Bay and Piankatank River using the standard 30 ft. fishing gear from a large research platform, with a 16 ft. gear towed from an outboard skiff or Chesapeake deadrise at shallow stations (:$; 12 ft.). Linda Pushee Mercer initiated the first random survey of the York River in 1971-72, as part of the results of a …

Reports

The Virginia Institute of Marine Science (VIMS) has conducted a bottom trawl survey of some fashion since 1955. Historically, sampling has occurred as mid-channel transects at fixed locations spaced at approximately five mile intervals. During the 1970's, the need for a random stratified survey of the main stem Bay and tributaries was realized and subsequently implemented. This program had a very large spatial coverage in various depth strata, but was very limited in its temporal component. Sampling occurred on a semi-annual basis primarily in January and February, and again in July (Wojcik and Van Engel, 1988a.) Based on previous results …

Habitat Requirements For The Softshell Clam, Mya Arenaria In The Chesapeake Bay, Patrick Baker, Roger L. Mann

Reports

Large populations of softshell clams persist only in relatively shallow, sandy. mesohaline portions of Chesapeake Bay. These areas are mostly in Maryland, but can also occur in the Rappahannock River. Virginia. In some other portions of the bay, especially polyhaline portions. sparse populations of soft shell clams persist subtidally. Restricted populations exist intertidally.

Softshell clams grow rapidly in Chesapeake Bay, reaching commercial size in two years or less. They reproduce twice per year, in spring and fall, but probably only fall spawnings are important in maintaining population levels. Major recruitment events do not occur in most years. despite heavy annual …

Habitat Requirements For The Hard Clam, Mercenaria Mercenaria, In Chesapeake Bay, G.Curtis Roegner, Roger L. Mann

Reports

The hard clam, Mercenaria mercenaria, is found along the eastern coast of North America from the Gulf of St. Lawrence to Texas. In Chesapeake Bay the hard clam is restricted to salinities above approximately 12 ppt. The abundances and distribution patterns of hard clams in Chesapeake Bay are based on studies performed nearly 20 years ago - a more extensive survey of hard clam resources is due. Statements concerning long term trends in populations are not feasible.

The basic anatomy of hard clams conform to that of venerid bivalves. Hard clams grow to a maximum shell length (anterior-posterior dimension) of …
