A Development Plan For The South Coast Inshore Trawl Fishery, Fisheries Department Of Western Australia

Fisheries Management Papers

In March 1986 discussions were commenced between officers of the Fisheries Department and the Australian Fisheries Service concerning management measures for trawl fishery in the Great Australian Bight. These measures were considered necessary as a Western Australian Company (Toskel Fishing Co.) had commenced fishing the area. Given the excess fishing capacity in other Australian trawl fisheries it was considered advisable to institute management at an early stage and control development of this deep water fishery. Concurrent with these developments, mainly directed towards the control of larger trawlers in deeper waters, several small Western Australian trawlers operating out of Esperance and …

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

Fisheries Management Papers

The Committee recognises that the exploitation rate on the rock lobster stocks is very high and that this factor is a major importance in formulating the advice on management measures. However, the Committee also recognises the high level of capital investment in the industry and that any recommendation which leads to a significant change in the management rules is likely to have a far reaching effect on many of the participants. Accordingly, the Committee endeavours to reduce to a minimum the year to year changes in the management rules. When changes are required the Committee places considerable weight on matters …

The Shark Bay Scallop Fishery: Discussion Paper, L. M. Joll

Fisheries Management Papers

Studies of the biology of the saucer scallop Amusium balloti in Shark Bay show that it is a highly fecund, broadcast spawner, with a long breeding season (from April to December). It is also a fast growing species, with the bulk of the recruits from a breeding season reasing fishable size by April/May of the next year, at which time they also enter their first breeding season. In recent years, however, the earlier part of the breeding season appears to have been the most important for production of recruits.

Further Options For Management Of The Shark Bay Snapper Fishery : Discussion Paper., P. Millington

Fisheries Management Papers

A limited entry fishing regime for snapper was introduced in Shark Bay in order to constrain growth in fishing effort. Additional measures were introduced to reduce the number of vessels in the fishery, control areas fished and limit permitted fishing gear, with the ultimate objective of reducing catches from traditional fishing areas to long term sustainable levels.

Fisheries Report No 76 - The Australian Herring Fishery In Western Australia, 1973 - 1985, Michael H. Walker, Diane P. Clarke

Fisheries Research Reports

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

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 78 - A Re-Examination Of The Methods Used For Handling Undersize Western Rock Lobsters, R. S. Brown, C J. Dibden

Fisheries Research Reports

The fishery for the western rock lobster, Panulirus cygnus (George) is the most important single species fishery in Australia, and one of the major rock lobster fisheries of the world, with catches over the last ten years (1973 to 1983) averaging approximately 9.8 million kg annually.

The continuing success of the fishery can be attributed mainly to effective management, which involves a complex system of regulations, the majority of which were introduced in 1963 and which are constantly being revised to accommodate changes in the fishery. One important piece of legislation, effective from 17 December 1965, was the introduction of …

Management Measures For The Cockburn Sound Mussel Fishery., H. G. Brayford

Fisheries Report No 74 - Marine Resources Map Of Western Australia- Part 2 - The Influence Of Oil On Marine Resources And Associated Activities With An Emphasis On Those Found In Western Australia, H. E. Jones

Fisheries Research Reports

Part 1 of the text accompanying the marine resources maps dealt with the resources and the morphological, hydrological and meteorological characteristics of the Western Australian coastal environment. This subsidiary part is concerned with the effects of oil on marine resources and associated commercial and recreational activities.

Accounts of oil on the seas due to natural seepages appeared in Europe in the sixteenth century on the return of Spanish and Portuguese ships from voyages to the Americas. One of the earliest reports of oil pollution from a man-made source was in 1754 when leakages from wooden petroleum barges were prevalent in …

Management Measures For The Shark Bay Snapper Fishery 1987 Season., P. Millington

Fisheries Management Papers

The 1986 Shark Bay snapper fishing season mirrored in almost all respects the situation which will apply when the limited entry regime is put into effect. It was thus an opportunity to assess how effective the measures recommended in the Report of the Shark Bay Snapper Fishery Working Group were in reducing effort in the fishery.

The King George Sound Purse Seine Fishery Working Group Report By The Chairman Mr. R. S. Brown To The Minister For Fisheries., R. S. Brown

Fisheries Management Papers

The King George Sound Purse Seine Fishery Working Group was formed to investigate the purse seine (mainly mulie) fishery in King George Sound and advise the Minister for Fisheries on options for future management. The fishery in King George Sound is unlike most fisheries because the fish stock (pilchards) which is exploited is part of a very extensive stock located right around the south and north west coast of Western Australia. Only relatively small portion of the total stock of pilchard enter King George Sound and comes under the very high exploitation there. The Working Group has proposed to the …

Fisheries Report No 66 - The Fishery For Perth Herring, Nematalosa Vlaminghi (Munro), C F. Chubb, N. G. Hall, R C.J. Lenanton, I. C. Potter

Fisheries Research Reports

Perth herring fishery over the last 30 years have been examined. While there are pockets of catches between Broome and Bunbury, those from the Swan Estuary and nearby inshore marine waters make by far the most important contribution to the fishery. In the Swan Estuary, the catches started rising in the 1950s in response to a demand by the rock lobster industry for bait and reached peak values in the late 1960s and early 1970s. Data are provided which demonstrate that catch per boat is a good index of catch per unit effort (CPUE) in the period since 1967 when …
