Double-Crested Cormorant Impacts On Sport Fish: Literature Review, Agency Survey, And Strategies, John L. Trapp, Stephen J. Lewis, Diane M. Pence

Symposium on Double-Crested Cormorants: Population Status and Management Issues in the Midwest

In response to concerns expressed by anglers, the U.S. Fish and Wildlife Service conducted an extensive review of published studies done throughout the United States and Canada on the impacts of double-crested cormorants (Phalacrocorax auritus) on sport-fish populations in open waters. The literature review indicated that fish species valued by sport and commercial anglers make up a very small proportion of the cormorants’ diet and that these birds have a minor effect on fish populations compared to the effects of sport and commercial fishing, natural predation, and other mortality factors. The Service sent a questionnaire to State agencies, …

Strategies To Reduce Double-Crested Cormorant Depredation At Aquaculture Facilities In Mississippi, David S. Reinhold, Charles A. (Bo) Sloan

Symposium on Double-Crested Cormorants: Population Status and Management Issues in the Midwest

Double-crested cormorant (Phalacrocorax auritus) depredation throughout the Southeastern United States has been on the increase over the past 20 years. The increase in depredation coincides with the growth of the aquaculture industry and an expansion of double-crested cormorant wintering populations throughout the Southeast. The U.S. Department of Agriculture–Animal and Plant Health Inspection Service–Wildlife Services plays a major role in reducing double-crested cormorant damage. Nonlethal harassment on farms, dispersal from night roosts, and lethal control have reduced double-crested cormorant depredation at aquaculture farms in Mississippi. However, the efficiency and compatibility of current methods of reducing double-crested cormorant depredation must …

Possible Effects Of Catfish Exploitation On Overwinter Body Condition Of Double-Crested Cormorants, James F. Glahn, Mark E. Tobin, J. Brent Harrel

Symposium on Double-Crested Cormorants: Population Status and Management Issues in the Midwest

Concurrent with the rapid growth of the Mississippi catfish industry during the 1980’s, there was evidence of similar growth of double-crested cormorant (Phalacrocorax auritus) populations wintering in the delta region of Mississippi. Observational and food habits studies indicate that this expansive industry, incorporating more than 100,000 acres of ponds, provides an enormous food base for overwintering populations estimated in recent years to exceed 50,000 birds. As much as 75 percent of the diet in certain roosting areas of the Mississippi delta consisted of catfish, and according to bioenergetic models cormorants can exploit as much as 940 metric tons …

Review Of The Population Status And Management Of Double-Crested Cormorants In Ontario, C. Korfanty, W.G. Miyasaki, J.L. Harcus

Symposium on Double-Crested Cormorants: Population Status and Management Issues in the Midwest

We prepared this review of the status and management of double-crested cormorants (Phalacrocorax auritus) in Ontario, with management options, in response to concerns expressed about possible negative impacts of large numbers of the birds on fish stocks, and vulnerable, threatened and endangered species. Double-crested cormorants are native to Ontario and were first recorded breeding on Lake of the Woods in northwestern Ontario in the late 1700’s. The birds spread eastward to colonize all of the Great Lakes by the 1930’s. A decline in cormorant populations on the Great Lakes from the 1950’s to the 1970’s has been attributed …

Information Needs For The Double-Crested Cormorant In Midwestern North America, As Identified By An Audience Survey , D.V. (Chip) Weseloh, Stephen J. Lewis

Symposium on Double-Crested Cormorants: Population Status and Management Issues in the Midwest

Double-crested cormorant (DCCO) research needs and data gaps were identified in the early 1990’s by Erwin (1995) and Nisbet (1995). Erwin (1995) recommended four areas of research: (1) large-scale banding and marking to determine age- and sex specific survival and fecundity, (2) studies of movements during migration and winter, (3) assessment of limiting factors such as contaminants and disease, especially in light of recent Newcastle disease in cormorants, and (4) evaluation of economic impacts of cormorants on cultured fishes and ways to reduce predation by fish-eating birds.

VCU Voice, 1988-1998

VCU Today, the University’s first official administrative organ, began as a somewhat irregular monthly publication but moved to a bi-weekly newspaper format in the 1980s. The newspaper changed its name to VCU Voice in 1988 and ten years later it appeared under the title UniverCity News. As it neared the end of its run as a physical newspaper, the publication became simply VCU News. These four publications were essentially the same periodical published under different titles by the Office of University Relations. VCU News appeared online for the first time in 2002.

Hyaluronan Synthase Of Chlorella Virus Pbcv-1, Paul L. Deangelis, Wei Jing, Michael V. Graves, Dwight E. Burbank, James L. Van Etten

Department of Plant Pathology: Faculty Publications

Sequence analysis of the 330-kilobase genome of the virus PBCV-1 that infects a chlorella-like green algae revealed an open reading frame, A98R, with similarity to several hyaluronan synthases. Hyaluronan is an essential polysaccharide found in higher animals as well as in a few pathogenic bacteria. Expression of the A98R gene product in Escherichia coli indicated that the recombinant protein is an authentic hyaluronan synthase. A98R is expressed early in PBCV-1 infection and hyaluronan is produced in infected algae. These results demonstrate that a virus can encode an enzyme capable of synthesizing a carbohydrate polymer and that hyaluronan exists outside of …
