An Evaluation Of The Effects Of Dredging Within The Arkansas River Navigation System, Volume Iii-The Effects Upon The Zooplankton Associations, Edgar D. Short, Eugene H. Schmitz

Arkansas Water Resources Center Technical Reports

The primary purpose of the zooplankton phase of the coordinated study was to attempt to evaluate the effects of dredging operations on the abundance, distribution, composition and complexity of the zooplankton communities within the aquatic system of the Arkansas River. The other phases of investigation include fish, macroinvertebrates, phytoplankton and some physico-chemical parameters. The lack of baseline data, needed for measurement of previous ecological conditions from which to detect past and future changes, proved to be a major impediment to any evaluation. Although the study involved only about 240 miles of the river in Arkansas, it should serve as an …

Fisheries Report No 26 - Report On Lake Chandala With Recommendations Of Its Importance As A Fauna Reserve, Alan Tingay, Susan R. Tingay

Fisheries Research Reports

The hydrology, vegetation, fauna and land use of Lake Chandala (31°30 'S, 115°57'E) is described on the basis of field and literature surveys. The significance of the Lake as a Straw-necked Ibis (Thresktornts spinicollis) nesting rookery is emphasised and recommendations are made for its acquisition and future management.

Fisheries Report No 23 - The Management Of Nature Reserves In Western Australia, Andrew A. Burbidge, Trevor Evans

Fisheries Research Reports

The number and area of Nature Reserves in Western Australia has grown rapidly in recent times. At 80 June 1975 there were 491 reserves with an area of 5 103 037 hectares. By 31 December 1975, with the inclusion of reserves for the Conservation of Flora in the definition of a Nature Reserve, there were 900 reserves totalling 5 317 965 ha. With the implementation of the Environmental Protection Authority's recommendations based on the Conservation Through Reserves Committee's Report on Systems 4, 8, 9, 10, 11 and 12 the Nature Reserve System will jump to 985 reserves with an area …

Farmland Preservation: A Broad Perspective From Indiana, Stephen W. Leatherman

HRI Papers

Preservation of farmland in America is just beginning to be seen as more that a local or state issue. This paper look at the problems facing agricultural land from the perspective of Indiana and prepares a background for future decisions about farmland preservation.

The Nursing Posture Of Domestic Sows And Related Behaviour, D. Fraser

Rearing Behavior Collection

The nursing behaviour of the sow commonly involves upward rotation of the udder, movements of the head and legs, and rhythmic grunting. Aspects of this behaviour were studied in several experiments with pregnant females, juveniles males, and suckling piglets. Many pregnant females lay down and assumed the nursing posture when their udders were first rubbed by hand. Those which initially appeared agitated in the experimenter's presence often failed to do so until after some habituation to the procedure. When the upper and lower rows of teats were rubbed alternately, the udder was usually rotated toward the stimulation. This rotation, like …

Fisheries Report No 22 - The Western Rock Lobster Fishery 1971 - 1972, 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 …

Report No 21 - A Resource Survey Of Woody Island, Archipelago Of The Recherche, J. Goodsell, A. Tingay, S. R. Tingay

Fisheries Research Reports

A resource survey of Woody Island was undertaken by the three authors from 26 October, 1975 to 8 November, 1975.

The island has some unusual faunal and floral features not yet recorded for the Archipelago. These are discussed.

Some problems in relation to the island's management are identified.

Genetic Variation In Scandinavian Brown Trout (Salmo Trutta L.): Evidence Of Distinct Sympatric Populations, Fred W. Allendorf, Nils Ryman, A. Stennek, G. Stahl

Biological Sciences Faculty Publications

Large differences in certain morphological traits between populations of brown trout (Salmo trutfa L.) in the lakes of northern Sweden led us to initiate an electrophoretic examination in an effort to understand the genetic structure of these populations. A total of 549 brown trout from four lakes were examined at 10 electrophoretically detected loci. Genetic variation was found at only three loci, coding for lactate dehydrogenase (LDH), alpha-glycerophosphate dehydrogenase (AGP), and creatine phosphokinase (CPK). A total absence of heterozygotes at the LDH-I locus in Lake Bunnersjoarna, coupled with significant correlations between LDH-I type and both CPK-I allele frequencies and …

Gene Duplication In The Family Salmonidae 111. Linkage Between Two Duplicated Loci Coding For Aspartate Aminotransferase In The Cutthroat Trout (Salmo Clarki), Fred W. Allendorf, Fred M. Utter

Biological Sciences Faculty Publications

The genetic control of the supernatant form of aspartate aminotransferase (AAT) was studied in the cutthroat trout (Salmo clarki) through a series of experimental matings. 509 individuals of eight families were examined to determine (1) the number of loci, (2) the mode of inheritance (i.e. disomic or tetrasomic), and (3) the linkage relationship of the loci involved. The variation observed is controlled by a duplicated locus resulting from a presumed tetraploid event of an ancestral salmonid. The inheritance experiments revealed .the presence of two disomic loci rather than a single tetrasomic locus. indicating that disomy has been reestablished …

Fisheries Report No 25 - The Western Australian Amateur Fishery For Australian Herring (Arripis Georgianus) - Results Of The 1973 Creel Census, R C.J. Lenanton, N. G. Hall

Fisheries Research Reports

Historically, the Western Australian production of Australian herring (Arrtpts georgtanus) has fluctuated from year to year in response to changing market demand. Prior to 1968, the annual catch taken by professional fishermen was relatively stable, ranging from 200 000 kg (approx. 500 000 pounds) to 450 000 kg (approx. 1 000 000 pounds). From 1968, commercial production has risen to a peak of 1 187 440 kg (2 617 857 pounds) recorded in 1972/73 (Table I). An increase in demand for herring as bait for the rock lobster fishery is considered to be the major factor involved in this observed …
