Lucerne Guidelines For Western Australia Principles For Integrating A Perennial Pasture Into Broadacre Dryland Farming Systems, Diana Fedorenko, Perry Dolling, Christopher Loo, Tom Bailey, Roy Latta Dec 2009

Lucerne Guidelines For Western Australia Principles For Integrating A Perennial Pasture Into Broadacre Dryland Farming Systems, Diana Fedorenko, Perry Dolling, Christopher Loo, Tom Bailey, Roy Latta

Bulletins 4000 -

Lucerne, often regarded as the queen of forages, has been used in agriculture for centuries. In Western Australia, however, its potential has never been fully realised despite its well-documented ability to dewater soils and reduce groundwater recharge. Over the years adoption has been limited by a range of factors including pests and diseases, soil acidity, grazing management and economics. During the last decade research has addressed these issues, paving the way for much greater impact at the farm and catchment level.

Skeleton Weed In Western Australia, Pocket Guide, State Skeleton Weed Committee, Department Of Agriculture And Food, Western Australia, Agriculture Protection Board

Bulletins 4000 -

The Skeleton Weed Program is a coordinated approach to eradicating skeleton weed in Western Australia. It is run jointly by the State Skeleton Weed Committee, the Department of Agriculture and the Agriculture Protection Board. It is funded through the skeleton weed levy collected from grain growers each harvest, and pooled in the Skeleton Weed Eradication Trust Fund.

Skeleton weed is targeted as a declared plant as it can drastically reduce crop yields (more than 1 tonne/ha in cereals) by competing for moisture and nutrients, mainly nitrogen. Its wiry stems impede headers and the sticky latex they contain cause machinery to …


Identifying Sub-Tropical Grass Seedlings, Brad Wintle, Geoff Moore, Phil Nichols Nov 2009

Identifying Sub-Tropical Grass Seedlings, Brad Wintle, Geoff Moore, Phil Nichols

Bulletins 4000 -

There is considerable interest in growing sub-tropical (or warm season) perennial grasses for out-of-season green feed, especially on the south coast and in the northern agricultural region (NAR). They consist of two types: creeping grasses, which spread by either above ground runners (stolons) or below ground runners (rhizomes) and bunch grasses, which are tufted and do not spread by runners.

The main species sown include Panic grass, Rhodes grass, Kikuyu, Setaria, Signal grass, Digit grass, and Bambatsi panic and are often sown as a mixture, comprising 2 or more species. This bulletin describes how to identify these grasses at the …

Fisheries research reports

Final FRDC Report – Project 2005/074

The Western Australian fishery is the only remaining significant fishery for pearl oysters in the world and comprises most of the exported pearl product of Australia, currently worth around $125 million annually. The majority of pearl shells used to culture pearls come from the pearling beds in the inshore waters near Broome. The fishery for pearl oysters preferentially targets smaller ‘culture’ shell (4-5 years age class, 120mm - 160mm shell length) that are more suitable for growing pearls, leaving larger MOP oysters (6+ age class, 175mm+) on the fishing grounds.

Silver-lipped pearl oysters (Pinctada …

In contrast, snapper (known as “pink snapper” in WA) has a continuous distribution around the southern coastline of mainland Australia and in New Zealand. Dhufish and snapper are the two most important exploited demersal scalefish species in the West Coast Bioregion (WCB) of WA, which extends from Kalbarri (27°S) to Augusta (35°S). This study examined regional variation in the biology of the two species, their …


Fisheries Research Report No.157 - The Western Rock Lobster Fishery 2003/2004 And 2004/2005, Simon De Lestang, E H. Barker Jun 2009

Fisheries Research Report No.157 - The Western Rock Lobster Fishery 2003/2004 And 2004/2005, Simon De Lestang, E H. Barker

Fisheries research reports

The 2003/2004 season produced the second highest catch recorded to date (13,684 tonnes), up markedly on the previous season’s catch of 11,415 t. Nominal effort in 2003/2004 (10,180,444 pot lifts) did not vary by nearly as much as did the catch, with total pot lifts declining only slightly (<1%) on the previous season. Season 2004/2005 produced a catch of 12, 236 tonnes, down on the previous season’s catch of 13,684 t. Similar to the catch, total nominal effort in 2004/2005 (9,789,671 pot lifts) also declined fairly substantially (4%) on the previous season. Recreational catches for the above two seasons were also down on their respective previous seasons by 52 and 11% each.

Puerulus settlement coast wide during 2003/2004 was below average, especially towards the southern and northern extremes of the fishery (Port Gregory and Jurien Bay south). This was also the case during the following season (2004/2005), although the poor settlement was more evenly spread across the entire fishery. Catch predictions from these …

Pasture Condition Guide For The Ord River Catchment, K Ryan, E Tierney, P Novelly Jun 2009

Pasture Condition Guide For The Ord River Catchment, K Ryan, E Tierney, P Novelly

Bulletins 4000 -

This guide has been produced as a tool for assessing pasture condition over a range of pasture types in the Ord River catchment. A pasture type is a distinctive mix of plant species, soil type and landscape position. For example, the Mitchell Grass Alluvial Plain Pasture type is a mixture of Mitchell grasses and other species occurring on black soil alluvial plains.

Pasture condition is an important factor affecting the potential of the rangelands for animal production and is a useful indicator for the sustainability of production.

Fisheries Research Report No. 191 - Maximising Survival Of Released Undersize West Coast Reef Fish, Rodney C J Lenanton, Jill St John, Brent S. Wise, Ian S. Keay, D J. Gaughan

Fisheries research reports

Final FRDC Report – Project 2000/194

In Australia, most fishery managers regulate the catch of recreational fishes using size and bag limits. The effectiveness of these regulations depends on the fish surviving capture and then release back into the water. Effective management of fishing using size or bag limits therefore requires an understanding of the rates of mortality of released fish and what factors are causing mortality so that these might be alleviated. The rates and likely causes of mortality of released WA dhufish (Glaucosoma hebraicum) and snapper (Pagrus auratus), breaksea cod (Epinephelides armatus) and baldchin groper (Choerodon rubescens) off …
