Some Basics Of Marron Production, Department Of Agriculture, Western Australia

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

marron are native to the South-West of Western Australia, and are keenly sought by inland fisher-men. However, supplies do not equal the apparent demand.

One solution is to cultivate marron in farm dams, or more intensively as a commercial enterprise.

This article suggests a few guidelines for marron production.

Aspects Of The Ecology Of Fish And Commercial Crustaceans Of The Blackwood River Estuary, Western Australia, R.C. J. Lenanton

Fisheries Report No 22 - The Western Rock Lobster Fishery 1971 - 1972, G. R. Morgan, E H. Barker

Fisheries Research Reports

The fishery for the western rock lobster* 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 catches. Inherent …

Fisheries Report No 25 - The Western Australian Amateur Fishery For Australian Herring (Arripis Georgianus) - Results Of The 1973 Creel Census, R C.J. Lenanton, N. G. Hall

Fisheries Research Reports

Historically, the Western Australian production of Australian herring (Arrtpts georgtanus) has fluctuated from year to year in response to changing market demand. Prior to 1968, the annual catch taken by professional fishermen was relatively stable, ranging from 200 000 kg (approx. 500 000 pounds) to 450 000 kg (approx. 1 000 000 pounds). From 1968, commercial production has risen to a peak of 1 187 440 kg (2 617 857 pounds) recorded in 1972/73 (Table I). An increase in demand for herring as bait for the rock lobster fishery is considered to be the major factor involved in this observed …

Fisheries Report No 14 - Wilson Inlet - A Seasonally Closed Western Australian South Coast Estuary, R C.J. Lenanton

Fisheries Research Reports

Considerable conflict has existed for many years between professional fishing, recreational usage and development in the west and south coast estuaries of Western Australia. One of the areas where intense conflict exists is Wilson Inlet.

The Government's task of advising the various interests concerned in these conflicts has been difficult, due to the lack of knowledge of estuarine fauna and environment in relation to usage and development.

The objective of this report is to present a preliminary description of the Wilson Inlet environment, to record the history of netting closures in the Inlet, and to discuss the history of the …

The Ecology Of Marron Cherax Tenuimanus (Smith) Introduced Into Some Farm Dams Near Boscabel In The Great Southern Area Of The Wheatbelt Region Of Western Australia, Noel M. Morrissy Dr

Fisheries Report No 13 - Results Of A Biological Survey Of The Shire Of Kent, Western Australia, N. L. Mckenzie

Fisheries Research Reports

The Department of Fisheries and Fauna is responsible for the conservation of the native fauna in Western Australia. The main approach to this problem has been the creation of reserves for "The Conservation of Flora and Fauna". These reserves, known as "Wildlife Sanctuaries", are controlled by the Western Australian Wild Life Authority - a Statutory Authority serviced by the Department.

The object of the acquisition programme is to develop a reserve system which will include, as far as possible, a full and permanent cross-section of the State's native floral and faunal assemblages and, at the same time, provide for the …

Fisheries Report No. 10 - An Investigation Into The Status Of Introduced Trout (Salmo Spp.) In Western Australia, Dr N. M. Morrissy

Fisheries Research Reports

Both brown (Salmo trutta L.) and rainbow (S. gairdnerii trout Richardson) have been introduced into inland waters of the south-west of Western Australia to provide an amateur sport fishery on a gamefish. The large indigenous marron (Cherax tenuimanus Smith) is present in most of these waters. The only large native fish present is the cobbler (Tand- anus bostocki Whitley) which, while highly edible like the marron, has no game-fish qualities.

Hatchery production of trout for stocking waters has been centred at Pemberton in the lower south-west since 1931 when Mr. Cyril Glew, acting in a private capacity, succeeded in hatching …

Fisheries Report No Vii (7) - Results Of A Biological Survey Of The Millstream Area, A. A. Burbidge Dr

Fisheries Research Reports

Millstream has long been recognised as an unique and outstanding area, both scenically and from a biological aspect. The area of prime interest consists of a series of deep pools in the bed of the Fortescue River (about 15 miles long including Gregory Gorge) and the springs and streams which feed them. Most of the springs are in the sides of the river bed but one of the largest is about 1% miles to the south. This feeds a swift flowing stream running north into the river bed.

The first Europeans to see the area were the exploring party led …

Fisheries Report No V (5) - Report On Marron In Farm Dams (Cherax Tenuimanus), N M. Morrissy

Fisheries Research Reports

A programme of selling marron (Cherax tenuimanus) to country dwellers for stocking farm dams, has been carried out by the Pemberton Trout Board for the past few years with considerable financial gain. In this case permission to sell the marron was granted by the Department of Fisheries and Fauna so as to encourage the provision of stocks of this large, freshwater crustacean for farmers in the dryer inland areas of the Southwest which are remote from sources of fresh fish and from natural stocks of marron.

The marron, however, have been sold indiscriminately, upon request, without any advice as to …

Barramundi are widely distributed in rivers and estuaries in the semi-tropical and tropical regions of the Indo- Pacific from South China to the Persian Gulf and along the coast of northern Australia. The limiting factors to the distribution appear to be temperature and salinity.

Fisheries Report No 3 - Western Australian Freshwater Fisheries, Donald D. Francois

Fisheries Research Reports

Most of the Australian States have a comprehensive system of inland waterways, Western Australia, however, is in a less fortunate position. True, the maps of the State show many rivers, but in much of the southern, more populous part, with no summer rain and no winter snow, the majority are virtually a chain of waterholes during the long summer months. At the same time, in a relatively small section in the south-west corner, there is a series of permanent streams flowing through what was originally dense forest. But apart from the three indigenous freshwater crustaceans, the marron (Cherax tenuimanus), the …

Fisheries Report No I (1) - The Shark Bay Fishery On Snapper Chrysophrys Unicolor (Quoy And Gaimard), B. K. Bowen

Fisheries Research Reports

As regards both catch and value, the Shark Bay snapper fishery is the second most important scale fishery in Western Australia. Until 195%, the fishing was done solely by means of hard-lines operated from beats drifting over the snapper patches. In 1959 traps were first used with great success and in 196) this method of fishing was again the principal technique.

Prior to the 1960 season there were several suggestions that the use of traps would have a deleterious effect on the fishery. On October 19, 1959, the Western Australian League of the Professional Fishermen's Association wrote to the Fisheries …

Fisheries Report Ii (2) - Preliminary Report On The Effectiveness Of Escape-Gaps In Crayfish-Pots, B. K. Bowen

Fisheries Research Reports

The Western Australian commercial crayfish, Panulinrus cy,nus George, (1962)", is caught in depths ranging from a few feet to approximately 45 fathoms. In the shallow waters large numbers of crayfish measuring, less than the legal minimum length are brought to the surface in the standard commercial crayfish pots. The law requires that these undersize crayfish be returned to the sea, but there is always the temptation to retain them for illegal sale. In addition, the undersize crayfish which are returned to the sea are often damaged by handling. The probability is that their mortality rate is higher than those which …
