Available in PDF, EPUB and Kindle. Book excerpt: The number of pound nets and the catch of· alosines per net continued to decline in 1975. Effort by stake gill nets increased but catch estimates declined. The James River yielded an estimated 853,847 pounds of American shad (down 47% from 1974) with the peak of the run at the end of March. Stake gill nets landed 246,036. pounds of American shad in the York River, a decrease from 1974. Estimates of Hickory shad landings declined 83% in the York River. Pound nets in the Rappahannock River had a 75% reduction in American shad catch and stake gill net catch was down 13% from 1974. River herring catch estimates were down 13% in the Rappahannock River. Pound net catches of American shad declined 47% while landings from stake gill nets increased by 44% from 1974 in the Potomac River. River herring landings increased 34% in the Potomac River.

Available in PDF, EPUB and Kindle. Book excerpt: This annual report covers the period October, .1973 through September, 1974. It is the seventh report generated by' the project, with 3-year completion reports prepared in 1970 and 1973. The project is continuing at VIMS and each year allows stronger conclusions to be made concerning trends in the basic population parameters studied. The 1970-1973 completion report was widely distributed in Virginia, libraries at fishery science institutes, and throughout the National Marine Fisheries Service. The completion report analyzed data from the entire history of the project. In many cases the entire summarized data core for a particular segment was presented, e.g. mortality rates and age composition of the run since 1966. Some jobs were presented in final. analysis form, because they were made inactive after 1973. The history of the foreign fleet activities was presented with an analysis of their effect on the anadromous alosids.

Available in PDF, EPUB and Kindle. Book excerpt: This report is part of a series of community profiles produced by the Fish and Wildlife Service to provide up-to-date information on coastal ecological communities of the tidal freshwater marsh community along the Atlantic coast from southern New England to northern Florida. Tidal freshwater marshes occupy the uppermost portion of the estuary between the oligohaline or low salinity zone and nontidal freshwater wetlands. By combining the physical process of tidal flushing with the biota of the freshwater marsh, a dynamic, diverse, and distinct estuarine community has been created. The profile covers all structural and functional aspects of the community: its geology, hydrology, biotic components, and energy, nutrient and biomass cycling.
