Report No 41 - A Survey Method For Identifying Roadside Flora Suitable For Conservation In Western Australia, John K. Scott

Fisheries Research Reports

A survey method for identifying flora suitable for conservation alongside roads in south-western Australia was derived from an examination of characteristics of road verges. Two roads, from Midland to Toodyay and from Armadale to Bunbury, were examined. Width of verge, weed cover, soil disturbance, vegetation structure, presence of public utilities, evidence of fire and the type of adjoining land were measured at one mile (1.6 km) intervals on both sides of the road. Also recorded were aesthetic qualities such as stands of beautiful trees and sites of special interest, e.g. the presence of rare plants.

Three variables, percentage weed cover, …

Fisheries Report No 48 - The Western Rock Lobster Fishery 1976 - 1977, G. R. Morgan, E H. Barker

Fisheries Research Reports

The fishery for the western rock lobster Panuldinus cygnus 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 …

Fisheries Report No 43 - A Pit Trap Survey Of Small Mammals, Lizards And Frogs On The Two Peoples Bay Nature Reserve, Stephen D. Hopper

Fisheries Research Reports

Ten pitlines were placed in open low woodlands near Moates Lake and in upland and coastal heathlands near Mount Gardner on Two Peoples Bay Nature Reserve during February 1980 and February 1981. The trapping program established that Common Dunnarts (Smitnthopsts murina) and Honey Possums (Tarstpes spencerae) were widespread in the reserve, and added three lizards and one frog to the list of vertebrates known to occur on the reserve.

Twenty mammals (15 native and 5 feral), four snakes, fifteen lizards, one tortoise and six frogs are now known on Iwo Peoples Bay Nature Reserve. They constitute a representative sample of …

Fisheries Report No 46 - The Amateur Fishery For The Western Rock Lobster, Pamela N. Norton

Fisheries Research Reports

A study of the amateur fishery for the western rock Lobster, Paulinus cygnus George, was commenced by the W.A. Marine Research Laboratories in August, 1976, and was concluded in December, 1978. The main aims of this study were to collect and analyse data to give some estimate of the distribution and magnitude of this amateur fishery.

Prior to this survey, the only catch and fishing effort data available was that obtained from the commercial fishery. Data from the amateur fishery were required in order to make a full assessment of the Level of exploitation of the stocks. In addition, 144 …

Report No 47 - 1980 Review Of Rainfall And Wetlands In The South-West Of Western Australia, J. A.K. Lane, D. R. Munro

Fisheries Research Reports

An account is given of the biological principles involved in decisions concerning duck-shooting seasons in the south-west of Western Australia.

The conditions for waterfowl which prevailed during 1980 are described through the use of rainfall statistics and data obtained from the Department's wetland monitoring programme.

1980 was the fifth consecutive year of below-average rainfall in all five Meteorological Districts of the south-west. 1976 to 1980 was thus' the south-west's driest five-year period since 1913 at least.

Low rainfall during 1980 resulted in a further decline in the condition of wetlands throughout most of the inland south-west, Few gauged wetlands increased …

Evaluation Of Impacts Associated With Reregulation Of Water Levels In Lake Mohave, Larry J. Paulson, John R. Baker, U.S. Water And Power Resources Service

Publications (WR)

The U.S. Water and Power Resources Service is considering reregulating Lake Mohave water levels to increase the net power benefit from Hoover Dam. Reregulation will not increase the generation capacity of the Hoover powerplant but it will enable the plant operation to be increased when the energy has greater monetary value. Energy generated at different times of the year has different market value, the highest being in January-March and July- September. By generating more power during these periods more net monetary benefit can be derived from Hoover Dam. The total volume of water released from Hoover Dam over an annual …

Mule Deer Habitat Guidelines, Richard M. Kerr

United States Bureau of Land Management: Staff Publications

The purpose of this Mule Deer (Odocoileus hemionus) Habitat Management Guide is principally to assist BLM managers and biologists in planning for and managing mule deer habitat on public lands administered by the Bureau of Land Management. For many years Federal land management agencies have made the distinction between the Federal responsibility for managing habitat and the State prerogatives of managing native wild ungulate populations. Certainly the two are inseparably linked. These responsibilities, and up to now "symbiotic relationships", are probably best described succinctly in Title 43 of the Code of Federal Regulations Part 24.

Fisheries Report No 38 - The Shark Bay Prawn Fishery (1970 - 1976), J. W. Penn, R. W. Stalker

Fisheries Research Reports

The existence of prawn stocks in Shark Bay, Western Australia, has been known since 1904 when the sailing ketch "Rip" on charter to the Western Australian Government, trawled large quantities of prawns from the area between Bernier Island and the mainland, Gale (1905). Although the Fisheries research vessel "Lancelin" trawled potentially commercial quantities of prawns from Shark Bay in the early 1950's, it was not until 1962 that a regular fishery was begun.

Today the prawn stocks of Shark Bay support Western Australia's largest and most consistent prawn fishery, having an annual production currently exceeding 2 000 tonnes. The catch …

Potential Use Of Hydroelectric Facilities For Manipulating The Fertility Of Lake Mead, Larry J. Paulson, John R. Baker, James E. Deacon

Publications (WR)

Analysis of historical nutrient data for Lake Mead indicates that the fertility of the reservoir has decreased which may be the cause for a corresponding decline in the largemouth bass population. However, it appears that fertility can be manipulated by altering the operation of the dam. The depletion of nutrients in the euphotic zone by phytoplankton and subsequent accumulation in the hypolimnion during summer and fall provide a natural nutrient gradient from which water of varying fertility can be drawn for discharge. This combined with alterations in the depth or seasonal pattern of discharge can possibly be used to enhance …
