In October 1992 a special Sub-Committee of the Rock Lobster Industry Advisory Committee was set up to consider and evaluate future management strategies for the rock lobster fishery. Pursuant to this the Director of Fisheries commissioned a marketing study that is the basis of this report. This study was commenced in early October 1993 and completed in May 1994. This study looked at the market implications of fishery's management strategies. In particular it assesses how the existing management structure limits the potential for the lobster industry to maximise the financial return, and in doing so provides an insight into the …

Long Term Management Strategies For The Western Rock Lobster Industry (4 Volumes) - Economic Efficiency Of Alternative Input And Output Based Management Systems In The Western Rock Lobster Fishery (Volume 2), Bob Lindner

Fisheries Management Papers

Since 1965, the Western Rock Lobster Fishery has been managed by what is essentially a license limitation scheme invoiving restricted entry for boats, and strict controls on the aggregate number of pots which can be used by the commercial fishing sector. By most measures, management of this fishery has been highly successful. Biological over-exploitation of the fish stock has been prevented, at least until recently. Notwithstanding these achievements, there is widespread concern that the future profitability, and even the viability of the industry is under threat unless the current management practices are reformed. Because of the complexity and intrinsic uncertainty …

Artificial Insemination Of Ewes With Frozen Semen, David Windsor

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

The judicious use of artificial insemination (Al) of ewes with frozen semen by ram breeders offers substantial gains for wool producers, but it promises even greater benefits if it can be used more widely within commercial breeding flocks.

In the Western Australian dairy industry, for example, genetic gains between 1971 and /986 are estimated to have been three times as great in herds bred by Al as in herds that were mated naturally.

Sheep And Wool Industries Need To Improve Their Performance, Rob Kelly, Tim Marshall

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

Today in Western Australia, sheep are run at slightly higher stocking rates, are achieving greater lambing percentages (up JO per cent) and higher wool cuts per animal ( up 0. 6 kg greasy) than in the 1960s. When all components of production are considered, the productivity of sheep fanns has increased by 2. 7 per cent per year over the past 35 years.

The challenge of the next decade is to achieve substantially greater rates of improvement than for past years if the sheep and wool industries are to maintain their significant place in Western Australian agriculture.

Breeding Better Malting Barleys, Ross Gilmour, Allen Tarr, Stefan Harasymow

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

Development of new barley cultivars in Western Australia has substantially improved the grain yield and quality of the State's barley crop. This has increased returns to barley growers and enhanced Western Australia's reputation in export markets as a major supplier of barley for malting and feed.

The State exports more than 200, 000 t of malting barley, 60, 000 t of barley malt and 150, 000 t of feed barley each year.

The major challenge for the future is to develop new, high yielding cultivars with improved malting quality.

In this article, the authors discuss the achievements of the past; …

The Wokalup Beef Cattle Selection Experiment, Alan Lymbery, Mick Carrick, Patrick Donnelly

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

The aim of the Department of Agriculture's long-term beef cattle selection experiment at Wokalup is to examine the effects of selection for faster-growing cattle on biological traits that may influence the productivity of a commercial beef herd. Selection lines were established from Hereford and multibreed cattle in 1977. Twelve years of selection have produced an increase in growth rate to weaning of about 120 g per day in both lines. About 40 per cent of this increase is the result of permanent genetic improvement.

We plan to compare these characteristics in cattle from the selection lines with cattle that have …

The Australian Lupin Collection - Passport Data For Wild And Semi-Domesticated Accessions Introduced Into Australia To 1990, J. C. Clements, W. A. Cowling

Grain and other field crops published reports

This report contains passport (including collection site) data and Commonwealth Plant Introduction (CPI) numbers for all wild and semi-domesticated Lupinus accessions introduced into Australia to 1990 (a total of 1071 accessions with CPI numbers between 10650 and 122692). Scientists or plant breeders with an interest in the characteristics of wild lupins from certain natural environments, such as high soil pH or low rainfall, will find this information invaluable when they select accessions for their experiments. The majority of the accessions were introduced by Western Australian scientists following collecting missions in the Mediterranean region, and the remainder were donated from institutions …

Bulletin No 4187 - Choosing Commercial Beef Bulls, David Barker

Bulletins 4000 -

This bulletin provides a method of placing realistic differences in value on young bulls offered for sale.

The prices paid for young bulls are often based on superficial appearance alone, and this has important financial implications for the purchaser. Different characteristics have either large or small effects on the net value of progeny produced. They are dependent on such factors as: the variability of different characteristics in cattle; differences in reliability of the assessment; the extent to which the characteristic is passed on to the progeny; the effect of the characteristic on realized net value of the progeny; the effect …

Differences Between Merino Strains And Studs, Roger Lewer

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

When commercial wool growers select Merino rams they often use the following pattern: the buyers first consider the main strains of Merinos in Western Australia - Bungaree, Collinsville and Peppin. They then study the 550 studs and numerous non-stud ram breeders in this State. Having chosen a breeder, they examine the rams on offer and buy their annual requirements from among these. Until recently, no objective information has been available on the differences between studs and strains in Western Australia's agricultural areas. However, as part of a major study at the Department of Agriculture's Great Southern Agricultural Research Institute, these …

In its report to the Ministier for Fisheries in November 1986, the Southern Western Australian Shark Working Group recommended the establishment of an Industry/Government Mangement Advisory Committee to provide managememt advice on the fishery to the Minister for Fisheries. The Advisory Committee held its first meeting in Albany on 23 February 1989. After being briefed on the state of shark stocks, the Committee's deliberations fell into three broad categories. In the first category there was sufficient time and information available to make a recommendation to the Minister for Fisheries. In the second category, discussion commenced, but was held over to …

Rock Lobster Industry Advisory Committee Report To The Minister For Fisheries., Rock Lobster Industry Advisory Committee

Fisheries Management Papers

The total catch of about 12.1 million kilograms for the 1987/88 season, based on processor returns, was an increase of 44% on the 1986/87 season. This very high catch, the third highest on record, resulted from an above average perulus settlement in 1983/84 and a "flow-on" of fast growing animals stemming from the expected high recruitment in 1988/990 caught as "reds" in 1987/88.

The Committee has identified five major elements related to the state of the rock lobster fishery upon which management advice is considered.

a) The undersize fraction of the population.

b) The "whites" which provide a significant proportion …

Breeding Field Peas In Western Australia, T N. Khan

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

Field peas have grown dramatically in popularity in western Australia in the past five years, with the planted area increasing from a mere few hundred hectares to about 70,000 ha in 1988. This growth may continue, as more than 700,000 ha of agricultural land is potentially suitable for growing field peas.

However, any such growth of the pea industry will require new cultivars with improved yield, adaptation and quality characteristics to meet local and export demands. The Department of agriculture therefore decided to start a selection and breeding programme to support the pea industry.

The Awassi Fat Tail Sheep Project, R J. Lightfoot

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

Australia's first Awassi fat tail lambs arrived at Kununurra in January 1987, completing the first major step in an ambitious project to establish a fat tail sheep breeding industry in this country.

Fat tail sheep bred in the Middle East attract much higher prices than merino wethers imported from Australia. The question to be resolved through our product development and market research is what premiums will Middle Eastern buyers pay for fat tail sheep bred in Australia and exported to the region.

The Department of Agriculture believes that there is potential for Sustralian producers to enter these new markets without …

Poultry Breeds Must Be Conserved : An Ideal Small Unit, R H. Morris

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

The Department of Agriculture is concerned at the rapid disapearance of some poultry breeds and strains over recent years. This trend has resulted from the disposal of flocks previously held by commercial poultry breeders and fanciers.

One way to stop the trend of disappearance of poultry breeds is for interested people to maintain a breeding flock of pure-bred poultry, making the progeny available to others.

This article describes a small unit suitable for housing breeding fowls. The unit is based on designs developed by the Department of Agriculture.

The Feral Goat Herd Of Faure Island, W H J Clarke

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

For just on a century there has existed on Faure Island, off the mid Western Australian coast, a herd of white feral goats.

The fleece of these animals, while similar in appearance to Angora mohair, has characteristics which somewhat resemble the luxury fibre cashmere, in that it comprises a fine dense undercoat, which sheds in early spring, as well as the hairy outcoat typical of all goat breeds except the Angora.

As there is little, if any, shedding in second or subsequent crosses, it would appear that the mating of Faure Island feral goats with traditional Angoras (or off-spring of …

Objective Measurement And The Stud Breeder, B R. Beetson

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

The movement towards sale of wool by certificate and sample highlights the significance of objective measurement in the Merino stud breeders' selection of his top rams.

This article suggests how stud breeders should use the Department of Agriculture's Flock Testing Service to gain genetic progress in wool producing ability without loss of visual buyer appeal.

Studs' use of the service will be evaluated in 1974.

New Cattle Breeds : How Do We Use Them?, J L. Anderson

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

Traditionally, beef production in Australia has been based on a few of the many breeds that developed in the United Kingdom. Pedigree breeding was used to maintain these breeds and was probably a sound policy, when combined with selection on performance, to maintain and concentrate merit in stud herds.

Emphasis on pure breeding has caused many prejudices against the practices of mixing and selection which were the original bases of breed formation.

Despite the adaptation of British breeds to the various environments in Australia there was, and still is, continuous interest in introducing other breeds of cattle to improve beef …

Sheep Meat Production Trial, Department Of Agriculture, Western Australia

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