Age And Growth Of The Utah Chub, Gila Atraria (Girard), In Panguitch Lake And Navajo Lake, Utah, From Scales And Opercular Bones, John M. Neuhold

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Previous literature indicates the opercular bone as a useful tool for the determination of age and growth of fish. The reliability and validity of this method is tested for two populations of Utah chub. Age and growth are calculated for 222 Utah chub collected from Panguitch Lake and 212 Utah chub collected from Navajo Lake, southern Utah, in 1952-1953 from both scales and opercular bones. Scales are measured with the aid of a projector. Opercular bones are measured directly. The center of growth of the opercular bone is posterior to the posterior lip of the fulcrum. Correction for curvature is …

Polyvinyl Alcohol-Fixative-Adhesive For Small Helminths And Protozoa, Glenn L. Hoffman

United States Fish and Wildlife Service: Publications

Following the method of Brooke and Goldman (1949), the author was able to fix, mount and stain small helminths and parasitic protozoa of fish in polyvinyl alcohol-fixative smears. However, because there was much granular material in the PVA-Schaudin's mixture, AFA fixative was substituted for the Schaudin's. The PVA went into solution readily using this fixative. The solution was accomplished by adding 5 grams Elvanol #71-30¹ to 62 ml. of water, heating to 950 C. until dissolved and adding 5 ml. of acetic acid, 1-1/2 ml. of glycerine, 10 ml. of formaldehyde, and 30 ml. of 95 percent alcohol.

The Occurrence Of Ornithodiplostomum Ptychocheilus (Faust) (Trematoda: Strigeida) In Fish And Birds, Glenn L. Hoffman

United States Fish and Wildlife Service: Publications

The metacercaria of Ornithodiplostomum ptychocheilush as been reported by Faust (1918; Illinois Biological Monographs 4(1): 1-120) from mesenteries of the squawfish, Ptychocheilus oregonensis (Richardson), and by Hughes and Piszcek (1928; Journal of Parasitology 15: 58-62) and Van Haitsma (1930; Transactions of the American Microscopical Society 49: 140-153) in the northeastern sand shiner, Notropis deliciosus stramineus (Cope). Van Haitsma (1930) found the adults in mergansers, Mergus americanus, M. serrator, Lophodytes cucullatus, and the old squaw duck, Harelda hyemalis. He also reared the metacercaria to the adult in young domestic ducks. Lyster (1940; Canadian Journal of Research 18D: 79-82) reported …

Mourning Dove Newsletter, Issue No. 7

United States Fish and Wildlife Service: Publications

This issue contains a summary of Mourning Dove populations data for assistance to the states and the Fish and Wildlife Service in preparing dove hunting regulations. It will also be of interest to all persons working on this important migratory game bird, whether in state game departments, institutions of learning, or individuals.

The previous issue was number 6, June 30, 1952. Since that date many of the southeastern dove projects have either been terminated or modified, so that information has not been gathered as extensively on populations during the past year as formerly. Consequently the major data available at this …

Visiting National Wildlife Refuges, Douglas Mckay, John L. Farley

United States Fish and Wildlife Service: Publications

If you travel in the wilder sections of our country, sooner or later you are likely to meet the sign of the flying goose-the emblem of the National Wildlife Refuges.

You may meet it by the side of a road crossing miles of flat prairie in the Middle West, or in the hot deserts of the Southwest. You may meet it by some mountain lake, or as you push your boat through the winding salty creeks of a coastal marsh.

Wherever you meet this sign, respect it. It means that the land behind the sign has been dedicated by the …

Avian Botulism Information On Earlier Research

United States Fish and Wildlife Service: Publications

Over the years, the disease, avian botulism, has been an important factor limiting populations of waterfowl, particularly in the West. Great numbers (doubtless millions) of ducks have died from this disease, and because of such heavy tolls, studies of the malady were begun early in the century and continued intermittently to the present time.

This summary brings up to 1950 the series of investigations on botulism by Wetmore (1918), Kalmbach (1930, 1932), Kalmbach and Gunderson (1934), Sperry (1947), and others. This information has been compiled as a service to those concerned with conservation of our waterfowl resources. A cooperative agreement …

Streptomyces Leidnematis N. Sp., Growing On Two Species Of Nematodes Of The Cockroach, Glenn L. Hoffman

United States Fish and Wildlife Service: Publications

In 1948 Mr. J. R. Wennemark called the writer's attention to a filamentous growth extending from the cuticle of Leidynema appendiculata and Hammerschmidtiella diesingi, oxyurid nematodes found in the intestine of the American roach, Periplaneta americana, which was collected in Iowa City, Iowa. Because of the extreme filamentous accumulation it was thought to be the mycelium of a fungus. Further observation on material from roaches reared in Grand Forks, North Dakota, and Detroit, Michigan, showed that the organism was not fungus but a member of the Actinomycetaceae. Slides were sent to Profs. R. S. Breed and H. J. …

Scaphanocephalus Expansus (Crepl.), A Trematode Of The Osprey, In North America [Research Notes], Glenn L. Hoffman

United States Fish and Wildlife Service: Publications

Examination of an osprey, Pandion haliaetus carolinensis furnished by Mr. Melvin Hoffman, Strawberry Point, Iowa, May, 1948, revealed about 30 trematodes which proved to be Scaphanocephalus expanses (Crepl.). This species which was redescribed in detail by Jagerskiold, (1904; Results of the Swedish Zoological Expedetion to Egypt and White Nile 1901 pt. 1) has a very large "expanded" flap-like anterior end and, to my knowledge, resembles no other trematode in that respect. The specimens have been deposited in the United States Nattional Museum Helminth Collection as No. 46437. Mr. Allen McIntosh (personal communication) has informed me that S. expanses has …

Life History Of The Utah Sculpin Cottus Bairdi Semiscaber (Cope) In Logan River, Utah, William M. Zarbook

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The study of the Utah sculpin in Logan River was based on 801 specimens collected during 1949 to March 1951. Numbers of fish examined for various catagories of the study wares length-frequency, 495; aging by vertebrae, 407; length-weight relationship, 601; and food habits, 275.

Fish were collected by use of an electric shocking machine generating 600 watts and 220 volts. Numbers of fish occurred as high as 150 per tenth mile of stream. Preferred habitats occurred in areas of coarse gravel and small rocks.

Vertebrae dissected from the fish were used in age determination. Length-frequency proved to be a general …

The Opercular Bone As An Indicator Of Age And Growth Of The Carp Cyprinus Carpio Linnaeus, William J. Mcconell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As part of an investigation of the non-game fish resources of Utah, a study of the age and growth rate of the carp was instituted. A preliminary investigation indicated that the opercular method was superior to several other methods of determining age and growth in the carp. Age and growth were calculated from the opercular bones of 330 carp collected at Ogden Bay Refuge in 1950-51. Distances to annuli were measured directly. The relationship between the posterior radius of the opercular bone and the standard length of the carp was curvilinear. Past growth was calculated with a logarithmic nomograph. Expected …

Age And Growth Of The Green Sunfish Lepomis Cyanellus Rafinesque In Northern Utah, Young E. Wright

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The green sunfish Lepomis cyanellus Rafinesque is a member of the sunfish family Centrarchidae. Curtis (1949) states that all members of the sunfish family are native only to North America, and are primarily warm-water fish. According to Jordan and Evermann (1934) the green sun-fish is generally abundant in all suitable waters from central Ohio and Indiana to the Rio Grande. Forbes and Richardson (1920) give the general distribution of the green sunfish to be from the Great Lakes to Mexico, the Mississippi Valley, and everywhere in small sluggish streams except east of the Alleghanies and in Canada. The green sunfish …

Bear River: A National Wildlife Refuge, Vanez T. Wilson, Rachel Carson

United States Fish and Wildlife Service: Publications

In the autumn of 1824 a buffalo-hide canoe drifted down the Bear River to its mouth in the Great Salt Lake of Utah. Within sight of that vast inland sea, Jim Bridger must have paused in amazement. Everywhere he looked-in the sky, on the open water, over the marshy borders of the lake-there were birds. It is said that the famous explorer of the western wilderness brought back reports that he had that day seen "millions of ducks and geese."

The Bear River marshes were soon to know years when their waterfowl were numbered, not by millions, but by thousands; …

Harvest Of Wild And Stocked Fish From The Logan River Drainage, Louis S. Pechacek

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Logan River heads in the southeastern corner of Franklin County, Idaho, and runs in a south and westerly direction. It enters the state of Utah through the northern boundary in the northeast corner of Cache County. The main stream is fed by two tributary streams which head in separate directions a few miles apart. The Franklin Basin branch is the main contributing tributary while the Beaver Creek branch is nearly as large.

An Additional Trematode From Tortugas, Florida, And A New Name For Opisthoporus Manter, 1947, Preoccupied, Harold W. Manter

Harold W. Manter Laboratory of Parasitology: Library Materials

Professor José M. Ruiz of Sao Paulo, Brazil, has kindly called my attention to the fact that the generic name Opisthoporus Manter, 1947 had been used several times previously, a condition which I had indeed checked but thoughtlessly forgot. For Opisthoporus Manter, 1947 (nec Opisthoporus Benson, 1851; Opisthoporus Minot, 1877; Opisthoporus Fukui, 1929), the name Postporus is proposed. The two species become Postporus epinepheli (Manter, 1947) and Postporus mycteropercae (Manter, 1947).

The combination Pleurogonus candidulus (Linton, 1910) (misspelled "candibulus" in my paper) had been made in 1946 by Ruiz (1946: 295) where, however, it was first printed " …

Mima Mounds: A Reply, Victor B. Scheffer

United States Fish and Wildlife Service: Publications

Major Grant believes that gophers behave in one way, and we believe that they behave in another-or we admit that we do not know exactly how they behave. I have plainly stated (1947, PP. 293, 294) that our evidence is indirect; that we have not seen gophers building a giant mound; that we do not know whether mound building is a contemporary or a historic process; and that we do not know whether the stimulus for mound building is a hardpan or a high water table or both.

Our main contentions are that mounds of the Mima type occur only …

Mattamuskeet: A National Wildlife Refuge, Rachel Carson

United States Fish and Wildlife Service: Publications

Mattamuskeet, Pea Island, and Swanquarter-- two on the mainland and one on the outermost barrier beach--are three National Wildlife Refuges in North Carolina that provide winter food and shelter for more than 100,000 waterfowl. Ducks, geese, and swans that in summer scatter across the northern rim of the world from Greenland to Alaska come down the sky lanes in the fall and in these refuges find the conditions they need to survive the hard months of winter.

At Mattamuskeet you can see one of the largest assemblages of Canada geese on the Atlantic seaboard and more of that giant white …

Chincoteague: A National Wildlife Refuge, Rachel Carson

United States Fish and Wildlife Service: Publications

The national wildlife refuge at Chincoteague, Virginia, is one of the newest in a chain of sanctuaries placed along the flight lanes of the waterfowl. Coming down from the north the principal links of the chain are Parker River, Montezuma, Susquehanna, Brigantine, and Bombay Hook. Then from Chincoteague the links run south, through Back Bay and Pea Island, Mattamuskeet and Cape Romain. Chincoteague, like other waterfowl refuges, is needed because birds migrate, and because in so doing they expose themselves to great dangers.

The migration of birds is one of the ancient spectacles of earth, and one of the most …

Parker River: A National Wildlife Refuge, Rachel Carson

United States Fish and Wildlife Service: Publications

The Parker River National Wildlife Refuge is New England's most important contribution to the national effort to save the waterfowl of North America. Many million Americans have a direct stake in the success of this effort: the 2,000,00o waterfowl hunters, the millions who find recreation and esthetic pleasure in observing and photographing the birds, and all those, whom there is no way of counting, who understand the value of preserving wildlife as part of America's natural heritage.

During the several generations in which the United States has been converted from a land preeminently wild and unsettled into an industrial and …

Contributions To The Study On Helminth Fauna Of Dillon Beach, Francis C. Gale

University of the Pacific Theses and Dissertations

Studies on trematodes of marine organisms of the Pacific Coast have been of a scattered and fragmentary nature. J. Stafford (1904) collected and described a number of trematodes from fishes of the north Pacific, but, in his historical survey, Manter (1926) fails to mention specifically any studies covering the waters south of Canada. More recently, in the United States, several contributions to the field have been made by Dr. John E. Guberlet at the University of Washington and at the College of the Pacific by Dr. Alden Noble, under whose guidance this study was made. James Park (1937) revised the …

Notes On The Trematode Subfamily Loimoinae (Monogenea), With A Description Of A New Genus, Harold W. Manter, Waldo L. Schmitt

Harold W. Manter Laboratory of Parasitology: Library Materials

The subfamily Loimoinae was named by Price (1936) for a peculiar monogenetic trematode, Loimos salpinggoides MacCal lum, 1917, from the gills of a dusky shark, Carcharias obscurus (Lesueur), at Woods Hole, Massachusetts, USA. Price (1938) redescribed this trematode, correcting several errors made by MacCallum. Manter (1938) described Tricotyle scoliodoni from a shark, Scoliodon terrae-novae (Richardson), from Beaufort, North Carolina, USA. He noted some similarities between Tricotyle and Loimos. The redescription of Loimos by Price increased these similarities.

Fishes Of The Middle West, Rachel L. Carson

United States Fish and Wildlife Service: Publications

The waters of the Mississippi River and the Great Lakes are a potential source of several hundred million pounds of food in the form of tasty lake and river fishes. This rich resource of the inland waters is important to a nation at war. Because of the growing meat shortage, people will eat more fish than in pre-war years. In the interior of the country, people will eat more fresh-water fish than before, because fish are good and nutritious and because, in the coming months, the shipments of rosefish, halibut, shrimp, and other seafoods that come to them from the …

Food From The Sea: Fish And Shellfish Of New England, Rachel L. Carson

United States Fish and Wildlife Service: Publications

Millions of Americans are developing new wartime food habits, trying foods they once neglected, turning to alternates for long familiar products. For everyone of the ten fish or shellfish that make up mere than four-fifths of New England's catch there are seven species little known or utilized, many of which could provide tasty and nutritious foods. Turning to these under-utilized species will conserve food resources by lifting the burden of over-exploitation from such fishes as cod and haddock and will augment dwindling supplies of protein foods. Exploring the seafood markets for unfamiliar species rewards the housewife and her family with …
