Long Term Management Strategies For The Western Rock Lobster Fishery (4 Volumes) - A Market-Based Economic Assessment For The Western Rock Lobster Industry (May 1994) (Volume 3), Marec Pty Ltd

Fisheries Management Papers

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 …

Review Of Recreational Gill, Haul And Cast Netting In Western Australia., F. B. Prokop

Fisheries Management Papers

In this paper the Recreational Netting Committee has addressed an extremely complex and controversial issue in a forthright manner. They have developed a set of management proposals which accommodates recreational netting while recognizing the concerns of non-netters and the general community. The Committee would like to stress that it considers this plan as a package. For example the Committee would be strongly opposed to the considerable operational restrictions contained under Section 5 if there were not a trade-off in terms of a fairer criteria for which estuaries are open as proposed in Section 6.2. Similarly, the Committee would not be …

Management Arrangements For The Southern Demersal Gillnet And Demersal Longline Fishery 1994/95 Season., Southern Demersal Gillnet And Demersal Longline Management Advisory Committee

Fisheries Management Papers

At its meeting of 7 April 1993 the Southern Demersal Gillnet and Demersal Longline Fishery Management Advisory Committee (hereafter called "the Committee) was advised of the Western Australian Fisheries Department's Research Division's concern over the status of shark stocks. All the data available indicate that whiskery sharks are severely over-exploited with stock levels declining by around 10% to 30% of original levels. Current levels of fishing effort are expected to cause the stock to decline further. Gummy sharks have high risk of over exploitation (stock has declined to 40% -50% of original levels. Dusty whaler stocks (bronze whaler) is uncertain …

Management Proposals For 1993/94 And 1994/95 Western Rock Lobster Season., Rock Lobster Industry Advisory Committee

Fisheries Management Papers

The Rock Lobster Industry Advisory Committee (RLIAC) in reviewing management arrangements for the rock lobster fishery, were concerned with two principle objectives: 1. That the management measures adopted would arrest the ongoing decline in breeding stock and seek to re-establish the number of breeding female rock lobster to levels consistent with known historic safe levels in the fishery. 2. That the management arrangements adopted would properly take into account market requirements in order to maximise returns to fishermen from an appropriate level of catch.

Fisheries Research Report No.100 - The Impact Of Trawling For Saucer Scallops And Western King Prawns On The Benthic Communities In Coastal Waters Off South-Western Australia, L. J.B. Laurenson, P. Unsworth, J. W. Penn, R. C.J. Lenanton

Fisheries Research Reports

A two year study was undertaken to collect data for the assessment of the impact of the saucer scallop and western king prawn trawl fisheries on the benthic communities in coastal waters off south western Australia, between 31°20'5 and 34°23'5 latitude.

Monitoring of reported commercial landings, on-board sampling of commercial catches, research vessel trawl surveys, experimental and exploratory trawling, and underwater television observations, have enabled the development of an extensive data-base on the fishery and benthic communities of the region.

These data indicate that the existing fishery operates on a number of relatively small, discrete grounds where saucer scallops or …

Rock Lobster Industry Advisory Committee Report To The Minister For Fisheries April 1992, Rock Lobster Industry Advisory Committee

Fisheries Management Papers

The Committee recommended: For the next five seasons the principal tools of management for the rock lobster fishery should be temporary and variable reductions in pot usage, without affecting the permanent pot entitlement of any operator. The number of pots a fisherman can use at any particular time within a season will be set in accordance with a schedule showing the total permanent pot authorisation and the number of pots permitted to be used. Maximum size controls. These sizes would be 120 mm for females and 130 mm for males north of Moore River and about 125 mm for females …

Test Detects Resistant Green Peach Aphids In Lupins, Francoise Berlandier, Ian Dadour

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

Confirmation of insecticide resistance in green peach aphid in Western Australia's lupin crops means farmers will have to choose insecticides much more carefully to control this pest. Resistance within an aphid population varies, and when resistant aphids are no longer exposed to insecticides, they may revert back to being susceptible in as little as one generation. Furthermore, when these revertant populations are exposed to the same insecticides in the future, resistance quickly reoccurs. In this article, the authors discuss a test to determine the extent of insecticide resistance in green peach aphid and how to manage it.

Australian Genetic Resources Of Trifolium And Ornithopus Species, Richard Snowball, Kevin Foster, Bill Collins

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

The introduction of improved pasture legumes into the cereal growing areas of southern Australia changed the face of our agricultural systems.

Subterranean clover was the first pasture legume to have a major impact, and the first varieties were available commercially in the 1930s. Since then, many varieties have been released, leading to the most recent release of Denmark, Gou/bum and Leura in 1992.

The development of burr, barrel and murex medics also had an impact on the pasture production of less acid heavy soils. Yellow serradella is still being developed for the more acid sandy soils.

This development of improved …

On The Trail Of The Native Budworm, Kevin Walden

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

Native budworm, the worst pest of lupins, is a bit of a uiill-o-the-unsp. Some years the native budworm moths go virtually unnoticed. In others, they appear in plague proportions without warning - in these years, the cost to growers in lost yield runs into millions of dollars.

If an early warning system can be developed to predict the extent of moth flights into lupin crops, and this seems possible, major crop losses could be averted.

The Department of Agriculture has started research to develop a system of predicting the size of spring flights of native budworm moth. We need to …

A Discussion Of Options For Effort Reduction., Southern Demersal Gillnet And Demersal Longline Fishery Management Advisory Committe

Fisheries Management Papers

The committee prefers to reduce effort in the fishery by improving the effectiveness of the 50 per cent reduction on transfer rule. To do this it is necessary to prevent the use of lease arrangements which act as a form of transfer.Some consideration could also be given to encouraging transfer of licences by protecting purchased units against further effort reductions. The Minister for Fisheries has determined that ownership statement must be completed prior to licence renewal each year. It is hoped that this will prevent licence holders from using lease arrangements to effect transfers and so avoid the loss of …

Wildlife Corridors In The Wheatbelt, Richard Hobbs, Denis Saunders

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

Native vegetation in the Western Australian wheatbelt now persists mostly in small areas that remained uncleared for various reasons. (See 'Remnant vegetation on farms is a valuable resource' on page 43.) On their own, most of these remnant areas are difficult to manage, and too small to retain viable populations of many of the birds and other animals found in the wheatbelt. These patches of vegetation can be linked by wildlife corridors, which may increase the ability of the wildlife to move about and persist in the area

Freshwater Aquaculture In Western Australia., Fisheries Department Of Western Australia

Fisheries Management Papers

Freshwater aquaculture in Western Australia is a relatively new industry. The first serious attempts began in 1975 after the Government relaxed the regulations on marron to allow for its farming and sale (at the legal minimum size of 17 mm carapace length). Since 1975, marron have been the focus of most attempts at aquaculture although in recent years trout, yabbies, freshwater aquarium fish and a number of other fish species have received greater attention. In 1984 the Minister for Fisheries established the Fish Farming Legislative Review Committee to review and make recommendations on the fish farming provisions of the Fisheries …

Future Policy For Charter Fishing Operations In Western Australia., P. Millington

Fisheries Management Papers

About 40 boats in Western Australia gain some of their income from taking recreational fishing parties out on charter. Half of these charter boats are also licensed commercial fishing boats. There are few Fisheries Department controls over charter boat fishing at present. However, with increasing tourism and leisure time, there are sound reasons for the Minister for fisheries to tighten up the controls over charter boat fishing to prevent over-exploitation in some areas or on particular stocks.

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 …
