For the past six years a bacterial infection has been the cause
of large losses of adult, spawning, American shad (Alosa
sapidissima) in the Coos, Millicoma and Smith Rivers of Oregon.
There was a sizable commercial fishery for shad in these rivers
and losses of fish due to this infection...
Selected life history aspects of American shad, Alosa
sapidissima, collected in Lake Umatilla of the Columbia River
during 1980 and 1981 were examined and compared to other shad
populations. Mean fork lengths of adult shad captured in
1981 were 405-, 415- and 423-mm for age III, IV and V males;...
This report gives information on the Coos River shad fishery, going into detail about recent (for 1957) trends in shad fishing such as licenses issued, total fish caught per location, and length frequency.
Machine separated flesh from American shad (Alosa
sapidissima) was evaluated for preparing heat set gel products.
Round fish frozen for 15) to 10 months at -18°C served as raw
material for processing investigations. The effectiveness of
various additives and processing procedures for improving gel
strength and sensory characteristics were determined....
Species distribution models (SDMs) are currently being used to identify essential fish habitat and guide
fisheries management worldwide. We present SDMs based on generalized linear mixed models (GLMM) of
the fall distribution or occurrence of juvenile American shad (Alosa sapidissima) and juvenile striped bass
(Morone saxatilis) in the Hudson River...
We examined the incidental catches of American shad (Alosa sapidissima) taken during research cruises and in commercial and recreational landings along the Pacific coast of North America during over 30 years of sampling. Shad, an introduced species, was mainly found over the shallow continental shelf, and largest catches and highest...
"This information report provides an updated summary of all coastal shad tagging studies conducted by the Fish Commission. I believe these studies represent the only shad tagged in Oregon coastal streams south of the Columbia River. No new field work is reported. My intent is to tabulate, consolidate, update, and...
We present a high-resolution Gravity Recovery and Climate Experiment (GRACE) mascon solution for Gulf of Alaska (GOA) glaciers and compare this with in situ glaciological, climate and other remote-sensing observations. Our GRACE solution yields a GOA glacier mass balance of -65 ± 11 Gta⁻¹ for the period December 2003 to...
This report describes the activities of the Coastal Rivers Section, including spawning ground surveys, inventory and obstruction surveys, shad and striped bass landing data, lake rearing studies, the physical and chemical characteristics of south coastal streams and various salmonid rearing and ecological studies.
