Review Of Helminths Of Fish-Eating Birds Of The Palaearctic Region. I. Nematoda, Glenn L. Hoffman

United States Fish and Wildlife: Staff Publications

The title is accurate but the subject is a little misleading. One would expect that the fish-eating birds will acquire nematodes from the fish they eat. On the contrary, with one exception, Eustrongylides tubifex, as far as is known none of these nematodes use fish as normal intermediate hosts. A few species use fish as paratenic hosts. The book consists of an Introduction (2 pages), General Account of Nematodes (4 pages), the Systematic Part (233 pages), List of Fish-Eating Birds and Their Nematodes (22 pages), References (29 pages) and Index (13 pages). There are keys to families, genera, and …

Avian Mortality Caused By A September Wind And Hail Storm, Kenneth F. Higgins, Michael A. Johnson

United States Fish and Wildlife: Staff Publications

In recent study of nonhunting mortality of wild waterfowl, Stout and Cornwell (1976) identified weather as one of the more significant causal agents. This paper describes an occurrence of spectacular avian mortality caused by a severe thunderstorm in North Dakota on 8 September 1977.

The storm was associated with a low pressure system in South Dakota. It developed about Noon CST north of Dickinson, traveled eastward and generally north of highway 1-94, and continued into Minnesota at about 5:00 p.m. CST. The system moved at about 60 mph (97 km/h) over a 300 mile (483 km) stretch of the state; …

Pasteurellosis Of Fishes, G. L. Bullock

United States Fish and Wildlife: Staff Publications

Septicemic infections of marine and estuarine fishes caused by Pasteurella have been known since the early 1960's. A Pasteurella caused a massive mortality of white perch (Morone americanus) and striped bass (M. saxatilis) in Chesapeake Bay in 1963 (Snieszko et al. 1964), and of cage-cultured yellowtails (Seriola quinqueradiata) in Japan in 1964 (Matsusato 1975). Pasteurellosis has spread to most areas in Japan where yellowtails are propagated and is one of the important bacterial diseases of the species. In 1972, 360 metric tons of yellowtails were lost. The terms bacterial tuberculoidosis and pseudotuberculosis (Kubota et …

Mycobacteriosis (Tuberculosis) Of Fishes, S. F. Snieszko

United States Fish and Wildlife: Staff Publications

Mycobacteria are widely distributed in nature. They are abundant in the soil, on the surface of plants, on the skin of vertebrates, in human food (e.g., milk and butter), and in animal feeds. Most mycobacteria are saprophytic, but some species are highly pathogenic and cause diseases such as tuberculosis and leprosy in humans, and similar diseases in mammals, birds, reptiles, amphibians, and fishes.

Mycobacteria that cause diseases of fishes differ considerably from those that cause diseases in humans and other mammals. Therefore, to avoid association between tuberculosis in mammals and mycobacterial infections in fishes, it is better to call the …

First Nesting Record Of The Caspian Tern In North Dakota, James F. Herman, Rodney A. Schmidt, Karen J. Wilson

United States Fish and Wildlife: Staff Publications

On June 28, 1977, we observed a single pair of Caspian terns (Sterna caspia) with two young on an island in Lake Williams in central North Dakota. This is the first confirmation of actual nesting by the Caspian tern in the State. Previously, breeding records had been postulated from sightings during the breeding season (Kantrud 1973; Robert Randall, personal communication; and Rohrt Stewart, personal communication).

Lake Williams is a shallow, saline, 420-hectare lake located near the town of Turtle Lake in east-central Mclean County. Mean depth during the breeding season (May-June) can range from 0 to 50 centimeters. …
