Fisheries Management Paper No. 22 - Economics And Marketing Of Western Australian Pilchards., Scp Fisheries Consultants Pty Ltd

Fisheries Management Papers

Most of the Western Australian pilchard catch comes from King George Sound and from the southern coast off Albany where the number of vessels allowed to catch has been controlled. Prospects for increasing production in this area are limited. However, there are indications that considerable quantities of pilchards could be caught in waters to the east and west of Albany, in the inshore declared purse seine development zone.

Before allowing fisherman to catch more pilchards in these waters, the Western Australian Government decided that an investigation should be undertaken of the Australian pilchard resources, the domestic and export market situation …

Nutritional Value Of Anaerobically Fermented Beef Cattle Wastes As A Feed Ingredient For Livestock, Ronald L. Prior, Andrew G. Hashimoto, John D. Crouse

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Waste is produced in large quantities in cattle feedlots, and this is a potential environmental pollutant. Recycling of feedlot waste as livestock feed has been investigated extensively as one means of lowering the disposable waste load. Refeeding fresh manure will only partially alleviate waste disposal problems. In one study, only about one-half of the manure collected daily could be refed, and the remainder was discarded.

Currently, there is increased interest in the development of a microbial process for recycling and utilizing feedlot wastes. Commercial digestors are in operation. In some of these systems, the potential exists for capturing methane as …

Zinc And Protein Levels In Finishing Diets Of Medium-And Large-Frame Steers, Wilson G. Pond, Robert R. Oldjen

Roman L. Hruska U.S. Meat Animal Research Center: Reports

The National Research Council lists the daily protein requirements of medium-frame and large-frame steers weighing 770 lb and gaining 2.2 lb daily as 1.7 and 1.8 lb, respectively; comparable values at 1,100 lb are 1.9 and 2.1 lb. These amounts of protein are expected to be provided for medium-frame steers weighing 880 lb and gaining weight at 2.2 lb daily by a diet containing 10.3% protein; the corresponding value for large-frame steers is 10.2% protein. Medium- and large-frame steers weighing 1,100 lb and gaining weight at 2.2 lb daily require 9.5% protein in the diet.

The zinc requirement of steers …

A Taxonomic And Distributional Study Of The Adult Caddisflies Of The Family Leptoceridae (Insecta: Trichoptera) Of West Virginia, James B. Glover

Theses, Dissertations and Capstones

A survey of the adult Leptoceridae of West Virginia revealed 27 species, 25 of which were state records. The most abundant genus in the state was Ceraclea which had ten different species. Triaenodes had six different species, while Oecetis had five. The most common species in the state included C. cancellatus, C. maculate, O. avara, and O. inconspicua. Species that were abundant only in the larger rivers of the western portion of the state included C. flava, C. maculata, Nectopsyche pavida, and T. ignita. C. neffi seemed to be most abundant in the higher elevations of the east. Ceraclea ophioderus, …

Lactational Evaluation Of Recombinant Bovine Somatotropin With Corn And Barley Diets, Wade Arthur Eisenbeisz

Electronic Theses and Dissertations

Forty-eight Holstein cows were randomly assigned wk 3 postpartum to a corn or barley diet from wk 4 through 44 postpartum. Cows within diets at wk 14 were randomly assigned to receive 0 (control), 10.3, 20.6, and 30.9 mg/hd/d of recombinant bovine somatotropin injected wk 15 through 44 postpartum. Forage dry matter was 80% corn silage and 20% alfalfa hay. Forage to concentrate ratio in total mixed diets varied from 50:50 to 70:30 with milk production. For the entire lactation, milk production of (29.7 and 29.1 kg/d) and 4% FCM (27.3 and ·25.9 kg/d) was lower for cows fed barley …

Comments On Estimating Population Rate Of Increase From Age Frequency Data, C. Renn Tumlison, V. Rick Mcdaniel

Journal of the Arkansas Academy of Science

Although many papers have described assumptions and calculations of r from different kinds of data, none has compared estimates of r for the same real data set under different assumptions. We used the age distributions of gray foxes collected during six trapping seasons to estimate and compare r and lₓ series derived under different assumptions. Because trapped foxes are killed, they are believed by some to represent death history data. We found this treatment underestimates mortality so overestimates survivorship and leads to erroneous conclusions about the population. Use of a projection matrix allowed prediction of population size and thus allowed …

A Mass Mortality Of Fishes In Lake Titicaca (Peru-Bolivia) Associated With The Protozoan Parasite Ichthyophthirius Multifiliis, Wayne A. Wurtsbaugh, R. Alfaro

Watershed Sciences Faculty Publications

In December 1981 , an epizootic of the protozoan parasite Ichthyophthirius multifiliis killed an estimated 18 million killifish Orestias spp. in Lake Titicaca, a high-altitude tropical system. Of the dead fish collected, 93% were adult O. agassii, a commercially important species that is abundant in the littoral zone. Juvenile Orestias spp., pelagic species, and some other littoral zone fis hes were slightly affected. lchthyophthirius multifiliis was probably introduced with exotic fishes brought to Lake Titicaca in the 1940s and 1950s.

Invertebrates Associated With The Pincushion Moss (Leucobryum Glaucum) And Underlying Soil, Timothy R. Leffler

Masters Theses

A faunal study of soil invertebrates collected from pincushion moss (Leucobryum glaucum) and underlying soil in a mixed deciduous forest of Charleston, Illinois, was performed because it was discovered that moss habitats have been largely overlooked by investigators.

The results from this study suggest that moss habitats provide a buffer area from the external physical environment, provide protection from predators, a place for oviposition and may be used as a food source. Twenty-seven orders of invertebrates were collected (66,023 individuals). Acarina (57.9%) and Collembola (37.9%) made up the majority of the invertebrate population. Three abiotic factors (temperature, moisture …

Taxonomy, Systematics, And Ecology Of Helminth Parasites Of The Ringed Seal, Phoca Hispida Schreber, In Alaskan Waters, Ann Marie Adams

Harold W. Manter Laboratory of Parasitology: Library Materials

The genus Orthosplaochnus Odhner, 1905 (Trematoda: Campulidae) was revised, with eight species recognized. Odhneriella Skriabin, 1915 was placed in synonymy with Orthosplanchnus, and Hadwenius was shown to be valid. Orthosplanchnus rossicus (Skriabin, 1915) (syn. Odhneriella rossica) was redescribed.

Inconsistencies in the diagnosis of the Anophryocephalus Baylis, 1922 (Cestoda: Tetrabothriidae) were discussed, along with the basis for generis revision. The taxonomic histories of certain genera of nematodes (e.g., Contracaecum Railliet and Henry, 1912; Dipetalonema Diesing; 1861; and Pseudoterranova Mosgovoi, 1950) were given to explain their present status.

The helminth-fauna of the ringed seal in the North Pacific was compared …

Northern And Southern Brook Lampreys (Ichthyomyzon Fossor And I. Gagei) In Minnesota, Philip A. Cochran, Timothy C. Pettinelli

Journal of the Minnesota Academy of Science

ABSTRACT - The presence of two species of brook lampreys, genus lchtbyomyzon, in Minnesota was confirmed. The northern brook lamprey (1 f ossor) occurs in the Blackhoof River of the lake Superior drainage. The southern brook lamprey (1 gagei)was found in the St. Croix River drainage above Taylors Falls. At least three microhabitats are used by 1 gagei during its life cycle. Adults prior to spawning are found in crevices beneath boulders in deep, fast water; spawning is associated with gravel substrate at the head of riffies; and larvae burrow in fine substrate in quiet water. The reproductive biology of …

Age, Growth, And Movement Patterns Of The Atlantic Stingray, Dasyatis Sabina, In A Florida Coastal Lagoon System, Thomas Henry Schmid

Retrospective Theses and Dissertations

Age, growth rates, and patterns of movement were studied in the Atlantic stingray, Dasyatis sabina, in the Indian River lagoon system in east central Florida. Age was estimated using the growth rings on the vertebral centrum and tretacycline marking. Tetracycline injections produced clear readable rings in all pups, but failed to be incorporated into the centra of adults. Females possess more centrum rings than males, but annual periodicity could not be verified. Growth rates were determined from aquarium held pups and adults and from tagged and recaptured animals. Males appeared to reach maturity in about two years, females in slightly …

Mandibular Dentition In Six Species Of Salamanders, Genus Plethodon (Caudata: Plethontidae), From Arkansas Using Scanning Electron Microscopy, Richard A. Atwill, Stanley E. Trauth

Journal of the Arkansas Academy of Science

The mandibular (dentary) dentition of six species of Plethodon (P. caddoensis, P. dorsalis, P. fourchensis, P. glutinosus, P. ouachitae, and P. serratus) from Arkansas was studied using scanning electron microscopy. In all species, the mandibular teeth were bicuspid, and each tooth possessed a prominent labial cusp and a well-developed, inward-curving lingual cusp. All species showed similar tooth crown features, except P. caddoensis which exhibited a reduced tooth height and a reduced lingual cusp (only slightly larger than the labial cusp). We compared our data with other studies on premaxillary, maxillary, and palatal teeth in Plethodon and found overall similarities in …

Distribution And Status Of The Brazilian Free-Tailed Bat (Tadarida Brasiliensis Cynocephala) In Arkansas, David A. Saugey, Gary A. Heidt, Darrell R. Heath, Tim W. Steward, Daniel R. England, V. Rick Mcdaniel

Both overwintering and maternity colonies were examined. Numbers of individuals ranged from one to several thousand.

Toe Tip Morphology In Six Species Of Salamanders, Genus Ambystoma (Caudata: Ambystomatidae) From Arkansas Using Scanning Electron Microscopy, Stanley E. Trauth, J. D. Wilhide

Journal of the Arkansas Academy of Science

The toe tip friction surface in six species of Ambystoma (A. annulatum, A.maculatum, A.opacum, A. talpoideum, A. texanum, and A. tigrinum) from Arkansas was examined using scanning electron microscopy. We found no sexual dimorphism in cell surface ultrastructure. Variation within and between species was considerable. The most active burrower, A. tigrinum, possessed the most disorganized cell surface, whereas the least active burrowers (A.annulatum, A.maculatum, and A. opacum) had morphologically similar and relatively smooth toe tips. In A. talpoideum and A. texanum, cell surfaces exhibited microprojections. Only these two species possessed mucous pores in close proximity to the friction surface. The …

Sex Ratios In Bobcat Populations, C. Renn Tumlison, V. Rick Mcdaniel

Journal of the Arkansas Academy of Science

Reported sex ratios in bobcat populations have suggested great variation ranging from strong male bias to strong female bias. Explanations offered for these observations have included factors of mobility, activity, behavior, inaccurate data collection, hunting pressure, and population density. Ratios are probably most representative during the winter, when females are no longer under constraints of parental care. Sex determination should be made by experienced observers and preferably through internal examination. The most productive direction for interpretation of validated ratios appears to be in terms of population density, hunting pressure, and the timing of harvest.

Bats Of Hot Springs National Park, Arkansas, David A. Saugey, Dianne G. Saugey, Gary A. Heidt, Darrell R. Heath

Journal of the Arkansas Academy of Science

A total of 309 bats in the families Molossidae and Vespertilionidae were captured. Species represented included: Eptesicus fuscus, Lasiurus borealis, Lasiurus cinereus, Nycticeius humeralis, Pipistrellus subflavus, and Tadarida brasiliensis cynocephala.

Eggtooth Development And Morphology In The Six-Lined Racerunner Cnemidophorus Sexlineatus (Sauria: Teiidiae) Using Scanning Electron Microscopy, Stanley E. Trauth

Journal of the Arkansas Academy of Science

Eggtooth development and morphology in the six-lined racerunner, Cnemidophorus sexlineatus, were examined using scanning electron microscopy. The anlage of the embryonic eggtooth emerges from the anterior surface of the palate relatively late during embryonic development. The eggtooth proper erupts through an epithelial sheath and grows anteriorly to project beyond the rostral scale. The mature eggtooth is hollow, has a wall made of enamel and dentine, possesses a sharply-curved body and has a flattened, pointed tip. The eggtooth is shed within several days after the young hatch.

Forest Habitat Use By White-Tailed Deer In The Arkansas Coastal Plain, T. B. Wigley Jr., M. E. Garner

Journal of the Arkansas Academy of Science

Forest habitat use by five radio-equipped white-tailed deer (Odocoileus virginianus) was monitored in the Arkansas Coastal Plain during 1982-84. The deer were located 821 times. Use of forest types was compared to expected use as calculated from availability. The study area was also divided into 491 two-hectare cells for which timber characteristics and number of deer locations were determined. Pine sawtimber was the most heavily used forest type in all seasons and was used more often than expected during spring. Also used more than expected were brushy areas (clearcut but not site prepared) during spring, summer and fall and openings …
