Rangeland Survey In Western Australia - History, Methodology And Applications, H. J. R. Pringle

Natural resources published reports

The rangelands of Western Australia lie to the north-west of the agricultural areas, extending east to the Nullarbor and north to the Kimberley (Fig. 1). The major areas that are used for pastoralism are most of the Kimberley and the Pilbara, nearly all of the mulga shrublands, plus some of the Goldfields gum belt and part of the Nullarbor Plain.


Fisheries Research Report No 91 - A Synopsis Of The Biology And The Exploitation Of The Australasian Pilchard, Sardinops Neopilchardus (Steindachner) Part Ii: History Of Stock Assessment And Exploitation, W. J. Fletcher Mar 1991

Fisheries Research Report No 91 - A Synopsis Of The Biology And The Exploitation Of The Australasian Pilchard, Sardinops Neopilchardus (Steindachner) Part Ii: History Of Stock Assessment And Exploitation, W. J. Fletcher

Fisheries Research Reports

This report summarises the studies which have provided information on the population characteristics and exploitation of the pilchard, Sardinops neopilchardus in Australia and New Zealand. This review was undertaken to determine whether existing data could be used to assess the status of Western Australian or other stocks or, alternatively, what additional information was required.

The mean size of pilchards caught varies among locations but, in general, fish are between 140 and 160 mm LCF, corresponding to ages 2 - 5 years. The length-weight relationship also varies between locations

Attempts to initiate pilchard fisheries have been hampered by the lack of …


Survey Of The Damage Caused To Trees By Goats, Steve Gherardi, Dick Mills, Tim Johnson Jan 1991

Survey Of The Damage Caused To Trees By Goats, Steve Gherardi, Dick Mills, Tim Johnson

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

The damage that goats can cause to trees is one of the major problems associated with their farming in the agricultural areas of Australia. It is also considered one of the main hindrances to the development of the goat industry. The Department of Agriculture s Goat Industry Development Unit surveyed mohair and cashmere producers to determine the prevalence of tree damage and its extent and severity; why producers believed goats damaged trees; and how producers minimised or prevented this damage.


Remnant Vegetation On Farms Is A Valuable Resource, Richard Hobbs, Ken Wallace Jan 1991

Remnant Vegetation On Farms Is A Valuable Resource, Richard Hobbs, Ken Wallace

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

Retention of native vegetation on farms is important both from an ecological and an economic point of view. Productivity in the paddocks ultimately will depend on the retention and replacement of trees and shrubs in the landscape. Remnants of native vegetation can play their part by helping to ensure the long-term viability of the agricultural system, as well as greatly enhancing the quality of life for those living on the land.


Fisheries Research Report No. 89 - Relationships Among Partial And Whole Lengths And Weights For Western Australian Pink Snapper Chrysophrys Auratus (Sparidae), M. J. Moran, C. Burton Jun 1990

Fisheries Research Report No. 89 - Relationships Among Partial And Whole Lengths And Weights For Western Australian Pink Snapper Chrysophrys Auratus (Sparidae), M. J. Moran, C. Burton

Fisheries Research Reports

Pink snapper, Chrysophrysauratus (Sparidae) is one of the major commercial and recreational fish in Western Australian inshore waters. This report presents a number of equations and conversion factors for management and scientific study of the species. Equations to calculate total lengths from partial lengths will facilitate enforcement of minimum legal lengths when snapper are landed in a "head-off" condition. For fisheries science purposes, there are equations to convert among total length, standard length and length to caudal fork; and to convert lengths and weights of processed fish to whole lengths and weights. Length-weight relationships are presented and compared with those …

Fisheries Research Report No 88 - A Synopsis Of The Biology And The Exploitation Of The Australiasian Pilchard, Sardinops Neopilchardus (Steindachner) Part 1: Biology, W. J. Fletcher

Fisheries Research Reports

There have been a large number of studies which relate to the biology and exploitation of the Australian pilchard, Sardinops neopilchardus. Much of the data, however, are located in journals which are hard to obtain, or in unpublished reports, and theses. With the increase in catch of pil­chards, particularly in Western Australia, a collation of all the available knowledge pertaining to pilchards in Australia and New Zealand was desired to help with the planning of future research into the Western Australian stocks of this species. This report contains all the information located on the biology of Sardinops neopilchardus, a companion …


Fisheries Research Report No 99 - An Investigation Of Weight Loss Of Marron (Cherax Tenuimanus) In Air During Live Transport To Market, Noel Morrissy, Peter Walker, Cliff Fellows, Warren Moore Jan 1990

Fisheries Research Report No 99 - An Investigation Of Weight Loss Of Marron (Cherax Tenuimanus) In Air During Live Transport To Market, Noel Morrissy, Peter Walker, Cliff Fellows, Warren Moore

Fisheries Research Reports

It is generally acknowledged that more competitive marketing of Australian fisheries and aquaculture harvests requires closer attention to post-harvest technology. Historically, these products have been marketed in a variety of forms (e.g., for freshwater crayfish:- boiled fresh, boiled frozen, whole or tails, and live). Some of these forms present a product of actual, or perceived, poorer quality to the retailer and consumer and, thereby, obtain low prices.

Freshwater crayfish can survive out of water for extended periods and, so, can be economically transported alive to the (overseas) restaurant chef. This live product commands the very highest price for the grower. …


Fisheries Research Report No. 87 - The Recreational Marron Fishery In Western Australia, Summarised Research Statistics, 1971-1987, N. M. Morrissy, C. J. Fellows Jan 1990

Fisheries Research Report No. 87 - The Recreational Marron Fishery In Western Australia, Summarised Research Statistics, 1971-1987, N. M. Morrissy, C. J. Fellows

Fisheries Research Reports

The freshwater crayfish Cherax tenuimanus, called marron, provides an important recreational fishery in the south-west of Western Australia. The annual fishing catch and fishing effort have been monitored by a log book research programme and an end-of season telephone survey since the 1971/72 season.

Following the 1986/87 fishing season, the fishery remained closed for two seasons (1987/88 and 1988/89) to permit stocks to recover from the effects of high total fishing effort and unfavourable water conditions over the preceding seasons

This paper provides a detailed account of the catch and effort statistics to the close of the 1986/87 fishing season, …

Fisheries Research Reports

This report presents information on the probable original introduction of the eastern Australian yabbie to farm dams in the Wheat-belt Region of the southwest of Western Australia (in 1932 at Narembeen); the probable type of yabbie (the "White Yabby", Cherax albidus Clark 1936 ) and source (Miram Swamp in the Victorian Wimmera); and, in 1985, the first voicing of concern over the spread of yabbies to natural habitats, particularly in the higher rainfall region of the southwest, together with current national and international concerns and advice on introduced aquatic species.

Commercial harvesting ("extensive" aquaculture) of existing yabbie stocks in wheat-belt …


Fisheries Research Report No. 83 - The Western Rock Lobster Fishery 1985/86, R. S. Brown, E H. Barker Jan 1990

Fisheries Research Report No. 83 - The Western Rock Lobster Fishery 1985/86, R. S. Brown, E H. Barker

Fisheries Research Reports

The 1985/86 annual catch of the western rock lobster Panulirus cygnus, totalled 7,191,968kg (Australian Bureau of Statistics (ABS) ), a drop of 1,774,497kg (19.8 per cent) on the 1984/85 season. The value of the 1985/86 catch was approximately $94M based on ABS figures. This drop in catch was almost entirely the result of lower puerulus (first post larval stage, approximately 9 to 11 months old) settlement three to four years before (i.e. 1982/83 and 1981/82). The fall in catch was accompanied by a drop in fishing effort (total number of pot lifts) of 12.1 per cent on the previous season …


Integrated Control Of Soil Insect Pests Of Potatoes, Stewart Learmonth, John Matthiesson Jan 1990

Integrated Control Of Soil Insect Pests Of Potatoes, Stewart Learmonth, John Matthiesson

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

One of the more difficult aspects of growing potatoes in Western Australia is controlling soil insect pests. These pests have become more troublesome because the highly effective and persistent organochlorine insecticides previously used to control the main soil pests, African black beetle and whitefringed weevil, were deregistered for agricultural use in 1987. Entomologists from the Department of Agriculture and CSIRO in Western Australia are collaborating to develop new management strategies for these pests that rely less on the use of chemical insecticides

Fisheries Report No 82 - Effects Of Fish Trapping On The Shark Bay Snapper Fishery, M. J. Moran, J. Jenke Oct 1989

Fisheries Report No 82 - Effects Of Fish Trapping On The Shark Bay Snapper Fishery, M. J. Moran, J. Jenke

Fisheries Research Reports

Traps have been a controversial method of catching pink snapper Chrysophrys auratus (Sparidae) around Shark Bay, Western Australia, since 1959. The history of the issue and the relevant regulations are reviewed; and results of in­vestigations into specific concerns about trap fishing are reported. Concerns of ghost-fishing by lost traps have been largely allayed by underwater TV film of snapper escaping from a standard snapper trap.

A major concern was that traps might physically damage the benthic fauna, e.g. corals. A TV survey showed that while fragile hard corals are abundant in shallower water nearby, the deeper snapper grounds themselves are …


The Benefits Of Weaning Cattle In The Kimberley, David Pratchett, Stuart Young May 1989

The Benefits Of Weaning Cattle In The Kimberley, David Pratchett, Stuart Young

Animal production and livestock research reports

The Kimberley region was populated with Shorthorn cattle from Queensland and New Sonth Wales in the 1880's. The descendants of these cattle known as Kimberley Shorthorn are still the predominant breed in the region. The relatively poor performance of these cattle under the harsh Kimberley conditions and the fact that changing the genotype can improve productivity was recently published (Pratchett D. WADA Journal No. 4 1988)

While the adoption of Bos indicus breeds is the correct move, improved husbandry can also increase the productivity of the Kimberley Shorthorn cow. The majority of cattle in the Kimberley are not weaned. Sometimes …


The Development Of An Efficient Lupin Harvesting Front, E D. Blanchard Jan 1989

The Development Of An Efficient Lupin Harvesting Front, E D. Blanchard

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

Harvest losses represent a significant reduction in lupin production and farm productivity.

Since 1984, the Department's Farm Machinery Research and Liaison Unit at the Dryland Research Institute has studied the lupin harvesting operation to improve its mechanical efficiency. An experimental and a prototype harvesting front were built and tested in the field. Guidlines for efficient lupin harvesting were produced, and commercial modifications developed.


Water Erosion Of Farmland In 1988, K J. Bligh Jan 1989

Water Erosion Of Farmland In 1988, K J. Bligh

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

Widespread heavy rains in WesternAustralian agricultural areas in 1988 caused severe water erosion, much of which could have been avoided by minimum cultivation and lower stocking rates.


Finishing Kimberley Cattle In The South-West, Brian L. Mcintyre, Bill Ryan, Neville Macintyre Jan 1989

Finishing Kimberley Cattle In The South-West, Brian L. Mcintyre, Bill Ryan, Neville Macintyre

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

The idea of integrating the Kimberley cattle industry with that in the south-west of Western Australia is no new, but until recently it had not been critically evaluated.

Over the past eight years the Department of Agriculture's Beef Cattle Branch has been assessing the performance of Kimberley cattle transported south for finishing in the agricultural areas.

This research has show that Kimberley weaners can be finished in the south, and that under the present (December 1988) economic conditions it is more profitable than running breeding cattle in the south-west and comparable with fattening store steers.


Coastal Plains : Land Use And The Environment, P R. George Jan 1989

Coastal Plains : Land Use And The Environment, P R. George

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

Five years ago, this Journal of Agriculture reported on ways to overcome severe algal pollution of the Peel-Harvey estuarine system, 70 km south of Perth.

Several articles in this Journal of Agriculture discuss improved agricultural practices on the Swan Coastal Plain in particular, although the principals will apply to similar eutrophication of the Slbany harbours, Wilson Inlet and the Vassee-Wonnerup Estuary. They also emphasixe the fine balance between man's demand for potable water and land for rural, industrial and urban use.


Choosing A Calcium Supplement For Sheep Fed Cereal Grains, R L. Peet, Michael Hare Jan 1989

Choosing A Calcium Supplement For Sheep Fed Cereal Grains, R L. Peet, Michael Hare

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

Sheep fed cereal grains as an energy source over summer usually need added calcium because cereal grains are generally low in calcium (for example, 0.03 per cent calcium compared to 0.26 per cent phosphorus), and there may not be a natural source such as clover, weeds, leafy stubble or edible bush in the paddock.

The safestt and most effective calcium supplement is finely ground limestone added to the feed, but some farmers have used other sources of calcium such as gypsum and superphosphate in this manner.


Breeding Field Peas : Screening Pea Lines, G H. Walton Jan 1989

Breeding Field Peas : Screening Pea Lines, G H. Walton

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

The early use of field peas in Western Australia was as a green manure crop or to feed stock be grazing the mature crop. Varieties which produced a large bulk of green material were sown. There was no control over insects or diseases.

In 1985, the Feseral Government recognised that to realize the potential of grain legumes grown throughout Australia, more research was needed.

One of the Grain Legume Research Council's (GLRC) priorities is species evaluation and variety improvement.

Since 1983, the Western Australian Department of Agriculture has screened advanced crossbred lines from the South Australian breeding programme for its …

Rangeland Surveys : A Basis For Improved Land Use, P J. Curry, Alan Payne

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

In mis 1988, the Department of Agriculture started a three-year programme to assist pastoralists in the Murchison River catchment to update land management planning of their stations. This Project, which is funded by the National Soil Conservation Program, will use interim results from a recent rangeland survey which has investigated and mapped the grazing recources throughout the region.

Elsewhere in Western Australia's pastoral areas, information on the productive potential of each area - and the management problems inherent for each class of land - are being used to help pastoral managers of Soil Conservation Districts rehabilitate degraded areas. This information …


Intensive Animal Industries In The Peel-Harvey Catchment, R W. Payne Jan 1989

Intensive Animal Industries In The Peel-Harvey Catchment, R W. Payne

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

The Swan coastal plain to the north and south of Perth is attractive for the intensive production of pigs and poultry for several reasons. It is close to markets, feed manufacturers and labour; has a less extreme climate than inland areas; and is underlain by a large reserve of high quality groundwater.

Because these are all intensive operations, large quantaties of nutrient-rich waste are produced over a very small area. They can severely damage ground and surface waters unless steps are taken to control the wastes which they produce.

This article oulines both the nature of intensive aniamal industries in …

The Australian herring (Arripis georgianus) ts a pelagic, largely marine, species which is relatively abundant in the south western waters of Western Australia. It is a close relative of the Australian salmon with a similar life history and habits which includes migrating for the purpose of spawning. The Australian herring is keenly sought both as a food fish and for bait. This report documents the fishery for this species as it has developed during the period 1973 to 1985.


Fisheries Report No 75 - The Commercial Shark Fishery In Temperate Waters Of Western Australia, D. I. Heald Jan 1987

Fisheries Report No 75 - The Commercial Shark Fishery In Temperate Waters Of Western Australia, D. I. Heald

Fisheries Research Reports

The Western Australian-based mixed gear fishery for edible shark generally operates from Geraldton to Esperance in waters shallower than 10 fm to a maximum depth of 100 fm. In 1983/84, the total catch was 1262 tonnes live weight. The total shark catch was taken by 158 gillnet boats, 45 longline boats and 152 handline boats. However, nearly two thirds (62%) of these boats caught 1 tonne or less in 1983/84 and were assumed to rely more heavily on other target fisheries than shark.

Of the 20 or so species of shark caught in W.A., 3 species together comprise two thirds …

Fisheries Report No 77 - The Western Rock Lobster Fishery 1983 - 1984, R. S. Brown, E. H. Barker Jan 1987

Fisheries Report No 77 - The Western Rock Lobster Fishery 1983 - 1984, R. S. Brown, E. H. Barker

Fisheries Research Reports

The fishery for the western rock lobster Panulirus cygnus is one of the most important single fisheries in Australia and an important export earner for the State. Western Australia produced 10,576 tonnes in 1983/84, out of a total Australian rock lobster catch, with the exception of Queensland, of 15,777 tonnes. The fishery is governed by a complex set of regulations which are designed to limit the total fishing effort to acceptable levels and to enforce a legal minimum size (Bowen 1971, Hancock 1981). Thus, it is important to monitor the state of the fishery constantly both to ensure that the …
