A seining survey of the fish fauna of the beach zone in the James River, Virginia, was conducted from July to December 1977. Weekly collections were made at 4 stations resulting in the capture of 17,602 individuals representing 36 species. Abundance and diversity were influenced by large catches of schooling and migratory species utilizing nearshore areas as a nursery ground. Freshwater species diversity peaked in August and September, while mesohaline species diversity peaked in July, September, and November. Cluster analysis was used to define 3 freshwater station groups representing warm, moderate, and cool water temperatures, but was not helpful in …
Deterioration Of Floy Fd-67 Internal Anchor Tags, M. Y. Hedgepeth, W. H. Kriete Jr., J. V. Merriner
Deterioration Of Floy Fd-67 Internal Anchor Tags, M. Y. Hedgepeth, W. H. Kriete Jr., J. V. Merriner

Yellow Floy FD-67 internal anchor tags were utilized in an experimental and field study of tag discoloration, tag legibility and fouling organisms. Most tags exhibited some degree of discoloration over time. The rate and extent of discoloration varied between two batches of tags purchased in different years. The legibility of a tag was not affected to a great extent by the degree of discoloration. Legends of some completely discolored tags were still readable. Fouling organisms eroded the vinylite covering and deteriorated the legends of some tags. Bryozoans, barnacles and tunicates were the most commonly encountered fouling organisms. Barnacles were the …

The Men All Singing : The Story Of Menhaden Fishing, John Frye
Books
The Men All Singing is a folk history as well as economic. It reaches back almost four centuries to tell of a little-known fishery that shares with cod the vista of our coastal life. Now the last decades of the twentieth century see great changes in all fisheries and our treatment of the waters that give so much of our food.

Striped bass (Marone saxatilis) were tagged in Virginia beginning in 1968. The 1970 yearclass of striped bass was tagged both in Virginia and New York in 1972. Fish tagged in Virginia were returned from New York to Maine while fish tagged in New York were returned from the Maryland portion of the Chesapeake Bay and the Potomac River. These data indicated that fish migrate from rivers in which they were spawned at different ages and that fish that migrate as 2 year olds remain together as a group until they are 3+ years. Therefore, within the Chesapeake Bay area there …
Growth And Survival Of Striped Bass And Striped Bass X White Perch Hybrids, J. Howard Kerby, Edwin B. Joseph
Growth And Survival Of Striped Bass And Striped Bass X White Perch Hybrids, J. Howard Kerby, Edwin B. Joseph
VIMS Books and Book Chapters
Experiments comparing growth and survival of striped bass (Morvne saxatilis) and striped bass female X white perch (M. americana) male hybrids indicated the hybrids were hardier than striped bass under the same experimental conditions. Striped bass exhibited health problems and resulting mortality which were not evident in the hybrids. Overall survival of striped bass in 2 replicate experiments was 42.5% after II months. whereas that of the hybrids was 84.2%. Striped bass and hybrid growth patterns were similar, but striped bass grew somewhat more rapidly than the latter. Mean specific (instantaneous) growth rates were roughly similar throughout the study. with …
