Comparison Of Artificial Substrates In Bottom Fauna Studies On A Large River, David R. Mcconville Jan 1975

Comparison Of Artificial Substrates In Bottom Fauna Studies On A Large River, David R. Mcconville

Journal of the Minnesota Academy of Science

During the summer of 1974, five types of artificial substrates and grab sampling were evaluated for sampling efficiency in pool No. 3 of the Upper Mississippi River. A total of 35 taxa of organisms were collected by the different techniques. Ponar grab sampling collected representatives of only eight taxa, whereas concrete block samplers collected 22 taxa . Intermediate in taxonomic collection were the Hester-Dendy samplers with 21 taxa, the barbecue basket samplers with 20 taxa, the Miller samplers with 17 taxa, and conservation webbing with 12 taxa. The barbecue basket samplers were the most productive, yielding at least five times …


Studies On Schistosome Dermatitis ('Swimmer's Itch") In Minnesota, Donald E. Gilbertson, Richard Wedlund Jan 1975

Studies On Schistosome Dermatitis ('Swimmer's Itch") In Minnesota, Donald E. Gilbertson, Richard Wedlund

Journal of the Minnesota Academy of Science

A preliminary study was conducted to determine the causative agents of schistosome dermatitis ( "swimmer's itch") in Minnesota and to determine the incidence schistosome infection in vector snails. A total of 1180 snails were collected from ten different localities, eight of which were sites of known schistosome activity . The incidence of schistosome infection in snails from individual areas was always less than 10 percent. Cercariae of Trichobilharzia ocellata from Lymnaea stagnalis were the most frequently-found schistosomes in our study.


Herpesvirus Disease Of Salmonids, Ken Wolf, Tokuo Sano, Takahisa Kimura Jan 1975

Herpesvirus Disease Of Salmonids, Ken Wolf, Tokuo Sano, Takahisa Kimura

United States Fish and Wildlife Service: Publications

A newly recognized virus, lethal for fry and fingerlings, has been isolated from brood stock rainbow trout (Salmo gairdneri) at the Winthrop National Fish Hatchery, Washington. A similar if not identical virus has been found in natural epizootics occurring annually since 1970 among fry of landlocked sockeye salmon (Oncorhynchus nerka) on Honshu Island, Japan. More recently, this agent was isolated from moribund and dead adult O. nerka on Hokkaido Island; Japan, but it remains to be determined whether or not the virus causes death in adult salmonids. The purpose of this leaflet is to bring the …


Fisheries Report No 19 - The Western Rock Lobster Fishery 1973 - 1974, G. R. Morgan, E H. Barker Jan 1975

Fisheries Report No 19 - The Western Rock Lobster Fishery 1973 - 1974, G. R. Morgan, E H. Barker

Fisheries Research Reports

The fishery for the western rock lobster* is one of the most important single fisheries in Australia and an important export earner for the State. The fishery is governed by a complex set of regulations which have been reviewed by Bowen (1971) and which are designed to limit the total effort to acceptable levels and to enforce a legal minimum size. It is thus important to constantly monitor the state of the fishery both to ensure that the effort is remaining within the accepted limits and that the regulations are adequately performing their function of maintaining reasonably stable catches. Inherent …


Calcium And Phosphorus Requirements In Lupin Seed Rations For Pigs, N W. Godfrey, A. R. Mercy Jan 1975

Calcium And Phosphorus Requirements In Lupin Seed Rations For Pigs, N W. Godfrey, A. R. Mercy

Journal of the Department of Agriculture, Western Australia, Series 4

Seed of lupin varieties now available can be combined with wheat or barley to produce a balanced diet for growing/finishing pigs, and lupin seed has become a popular ingredient of pig rations.

As a protein concentrate, lupin seed is a satisfactory alternative to meatmeal, provided adequate amounts of calcium and phosphorus are added as supplements. Without the addition of these elements to rations of lupin seed and grain, a number of problems are likely to arise.

Trials at the Medina Pig Research Station have shown that Christmas Island rock phosphate is the cheapest and most convenient source of supplementary calcium …


The Behaviour Of Swine, J. P. Signoret, B. A. Baldwin, D. Fraser, E. S. E. Hafez Jan 1975

The Behaviour Of Swine, J. P. Signoret, B. A. Baldwin, D. Fraser, E. S. E. Hafez

Mammalogy Collection

The pig was a forest-dwelling animal from the beginning of its history. In some parts of the world it has been domesticated for at least 7000 years. The European breeds of domestic swine were derived from the local wild pig, Sus scrofa. Herds ranged in pastures and forests and kept indoors only for fattening. The breeds in the Far East were derived from another wild pig, Sus vittatus, a smaller animal with shorter legs and a higher reproductive ability (Mohr 1960; Zeuner 1963). The two types interbred readily. The modem breeds of pig evolved from different crossings between the two …


Special Report On Controlling America's Pet Population Jan 1975

Special Report On Controlling America's Pet Population

Special Reports

HSUS estimates that public and private animal control programs cost the nation as much as $500 million a year. Much of this expense is required for the feeding and care of unwanted animals during the 5 to 10 days they are held for adoption, killing the 80% that are not adopted or redeemed, and disposing of the carcasses. The result is both an unconscionable waste of life and a needless drain on public and private money.

A large part of the blame for people undertaking pet ownership without having made a total commitment to the animal lies with the pet …

Journal of the Arkansas Academy of Science

A total of 337 bluegill from Lake Fort Smith were used for this study. Annuli were formed between late February and early June, the younger fish forming annuli earlier than older fish. Total length-scale radius and length-weight relationships were determined. Growth of bluegill was compared with that reported in other studies. Growth curves were analyzed by the Von Bertalanffy growth formula and the parameters were evaluated in terms of physical and biological factors.


Factors Affecting The Development Of Lipase Flavor In Butter, Lawrence I. Bell Jan 1975

Factors Affecting The Development Of Lipase Flavor In Butter, Lawrence I. Bell

Electronic Theses and Dissertations

Current trends in the dairy industry have resulted in an increase in the incidence of lipase flavored butter. Raw cream, fresh and aged 24 h, was divided into 3 fractions and heat treated at temperatures of 72 C, 85 C, and 93 C. Each fraction of cream was churned into butter, with the butter divided and stored at -28. 9 C and 4.4 C. Lipase flavor development was measured organoleptically, by acid degree value (ADV), and free fatty acids (FFA) using a colorimetric procedure. Age of the cream had a significant effect (P< .01) on FFA and. ADV .levels, whereas heat treatment .of the cream had a significant effect (P< .01) on flavor only. Storage time had a significant effect (P< .01) on FFA, ADV, and flavor and the temperature of storage had a significant effect (P< .01) on FFA ·and flavor. Correlation between FFA and ADV was 0.86. There was no correlation between flavor and either JTFA or ADV

Electronic Theses and Dissertations

The present study was conducted to determine if the protein level of layer diets could be lowered from the: commonly used 16 percent to 12 percent by supplementation of some of the essential amino acids without reducing the performance of hens. The amino acids used were methionine, lysine, tryptophan and isoleucine. Egg production, egg shell thickness, interior egg quality, body weight, feed efficiency and free amino acid content of the albumen of eggs produced were criteria used to measure the (--) to treatment.


Treflan And The Oxygen Consumption Of Green Sunfish (Lepomis Cyanellus), Barbara Jo Warner Jan 1975

Treflan And The Oxygen Consumption Of Green Sunfish (Lepomis Cyanellus), Barbara Jo Warner

Masters Theses

Oxygen consumption rates of 51 green sunfish (Lepomis cyanellus, Rafinesque) were monitored over five hours exposure to Treflan E.C. concentrations of 0, 0.32, 0.56, 1.0, and 2.0 ppm. There was a great variation in the responses of the fish at each concentration; and Student's t-tests revealed no significant differences. However, graphs of the mean hourly oxygen consumption rates showed certain trends. During the fifth hour of exposure, there appears to be an acclimation to the Treflan at concentrations of 0.32 and 0.56 ppm; but no such acclimation at the higher concentrations of 1.0 and 2.0 ppm. Hourly oxygen …

Taxonomy And Zoogeography Of Lemmus Spp. (Rodentia: Arvicolinae), With Notes On Laboratory-Reared Lemmings, Robert L. Rausch, Virginia R. Rausch Jan 1975

Taxonomy And Zoogeography Of Lemmus Spp. (Rodentia: Arvicolinae), With Notes On Laboratory-Reared Lemmings, Robert L. Rausch, Virginia R. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Lemmings of the genus Lemmus Link, 1795, have long attracted interest because of the high numerical densities attained at intervals by their populations. In earlier times, in northern Europe, such events seemed so remarkable as to be explained by some as a consequence of the animals' having fallen from the sky (HaGSTROM 1749). During the last 25 years, lemmings have been the object of intensive ecological investigation in Eurasia and North America, although there has been no consensus concerning their taxonomic relationships. In 1959, a colony of brown lemmings from arctic Alaska was established in our laboratory, primarily to provide …
