Fisheries Management Paper No. 15 - Draft Management Plan For The Control Of Barramundi Gillnet Fishing In The Kimberley., R. S. Brown

Fisheries Management Papers

This management plan sets out a number of options for the control of commercial gillnet fishing for barramundi in the Kimberley. the plan focuses on existing commercial fishery, and on the fishermen consulted during the process of developing these management arrangements. However, the barramundi stocks of the region are increasingly exploited by large numbers of both local and tourist recreational fishermen whose needs must also be catered for. Because recreational fishermen are not easily identified or contacted as a group, I have endeavoured in this foreword, to set out the management options which best take into account the future needs …

Economics And Marketing Of Western Australia Pilchards., Scp Fisheries Consultants Pty Ltd

Fisheries Management Papers

The 1986/87 Australian catch was about 8,300 tonnes. At present levels of fishing,it has been suggested that this could be substantially increased. The fishery is not in danger of over-exploitation. Rather, the problem could be that there is more fish available than existing markets could absorb. However, there are prospects for increasing the present volume of fish sold domestically and for developing new products and markets in Australia and overseas.

Age And Growth Of The Tautog, Tautoga Onitis (Pisces: Labridae), From Lower Chesapeake Bay And Coastal Waters Of Virginia, E. Brian Hostetter

Biological Sciences Theses & Dissertations

The tautog, Tautoga onitis (Pisces: Labridae), is rapidly gaining popularity in Virginia by anglers, spearfishermen and specialized commercial interests. In Virginia, tautog are seasonally abundant on hard bottom substrates in nearshore (ca. 2-10 m) habitats and inhabit offshore wrecks and reef areas (ca. 10-30 m) year round. Habitat restriction and slow growth of the species coupled with recent technological advances in marine electronics which simplify locating tautog populations by user groups may contribute to overexploitation of tautog within the region.

Tautog were collected over a two year period from the lower Chesapeake Bay and nearshore waters of the Atlantic Ocean …

Draft Management Plan For The Perth Metropolitan Purse Seine Fishery, P. Millington

Fisheries Management Papers

As part of a development strategy for inshore purse seine fishing along the Western Australian coast this plan proposes management measures for the purse seine fishing boats operating along the coast near the greater Perth Metropolitan area. Using as a basis the restricted entry Cockburn sound purse seine fishery, the plan proposes the introduction of a limited entry regime for inshore purse seine fishing between Lancelin to just south of Mandurah. This regime will permit management of the available pelagic fish stocks in the area and also protect the economic position of the existing participants by providing an environment for …

Fisheries Report No 80 - Potential For The Development Of A Tuna Industry In North West Australian Waters, J. P. Robins

Fisheries Research Reports

Information available on the abundance of tuna off north west Australia, gathered on surveys by both ship and aircraft, the presented in order to identify opportunities for the sourcing of raw material for the Western Australian tuna canning industry. Identification of the constraints and potential for industry development of these resources is made focusing on the area considered most favourable, types of vessels used, fishing methods and strategies required for the development of such resources in the event that there is some identified prospect of viable commercial development.

The South West Trawl Fishery Draft Management Plan., P. J. Millington

Fisheries Management Papers

This paper outlines a proposal for management of trawl fisheries operating in waters less than 200m deep between the Moore River north of Perth and Cape Leeuwin. Off Fremantle, potential and actual user conflicts between trawling and the requirements of recreational fishing and other forms of commercial fishing point to the need to gradually phase out trawling in this area. A limited entry fishery, with no licence transferability, is therefore proposed.

Sport Fishing For Marron In Western Australia - Management For The Future : A Discussion Paper On Management Options For The Marron Fishery., Fisheries Department Of Western Australia.

Fisheries Management Papers

The number of marron that may be caught each year without seriously jeopardising the long term future of fishery is limited. The situation deteriorated still further after another winter of low rainfall in 1987 and as the 1987-88 summer drew closer it became doubtful whether the State's marron stocks could withstand another season of hard fishing pressure. Thus, it was considered necessary to ban all fishing for marron during the 1987-88 season. This discussion paper has been prepared to help start the ball rolling in the right direction, and ensure any measures taken to safeguard the fishery are backed up …

Fisheries Management Paper No. 22 - Economics And Marketing Of Western Australian Pilchards., Scp Fisheries Consultants Pty Ltd

Fisheries Management Papers

Most of the Western Australian pilchard catch comes from King George Sound and from the southern coast off Albany where the number of vessels allowed to catch has been controlled. Prospects for increasing production in this area are limited. However, there are indications that considerable quantities of pilchards could be caught in waters to the east and west of Albany, in the inshore declared purse seine development zone.

Before allowing fisherman to catch more pilchards in these waters, the Western Australian Government decided that an investigation should be undertaken of the Australian pilchard resources, the domestic and export market situation …

Comments On Estimating Population Rate Of Increase From Age Frequency Data, C. Renn Tumlison, V. Rick Mcdaniel

Journal of the Arkansas Academy of Science

Although many papers have described assumptions and calculations of r from different kinds of data, none has compared estimates of r for the same real data set under different assumptions. We used the age distributions of gray foxes collected during six trapping seasons to estimate and compare r and lₓ series derived under different assumptions. Because trapped foxes are killed, they are believed by some to represent death history data. We found this treatment underestimates mortality so overestimates survivorship and leads to erroneous conclusions about the population. Use of a projection matrix allowed prediction of population size and thus allowed …

Sex Ratios In Bobcat Populations, C. Renn Tumlison, V. Rick Mcdaniel

Journal of the Arkansas Academy of Science

Reported sex ratios in bobcat populations have suggested great variation ranging from strong male bias to strong female bias. Explanations offered for these observations have included factors of mobility, activity, behavior, inaccurate data collection, hunting pressure, and population density. Ratios are probably most representative during the winter, when females are no longer under constraints of parental care. Sex determination should be made by experienced observers and preferably through internal examination. The most productive direction for interpretation of validated ratios appears to be in terms of population density, hunting pressure, and the timing of harvest.

Forest Habitat Use By White-Tailed Deer In The Arkansas Coastal Plain, T. B. Wigley Jr., M. E. Garner

Journal of the Arkansas Academy of Science

Forest habitat use by five radio-equipped white-tailed deer (Odocoileus virginianus) was monitored in the Arkansas Coastal Plain during 1982-84. The deer were located 821 times. Use of forest types was compared to expected use as calculated from availability. The study area was also divided into 491 two-hectare cells for which timber characteristics and number of deer locations were determined. Pine sawtimber was the most heavily used forest type in all seasons and was used more often than expected during spring. Also used more than expected were brushy areas (clearcut but not site prepared) during spring, summer and fall and openings …

The Southern Redbelly Dace, Phoxinus Erythrogaster (Rafinesque), In Clark County, Illinois, Susan C. Darrow

Masters Theses

Population and feeding ecology of the southern redbelly dace, Phoxinus erythrogaster (Rafinesque), was studied at Rocky Branch Nature Preserve, sections 29 and 30, T12N, R12W in Clark County, Illinois. Three stations designated along the eastern portion of Rocky Branch stream were seined bimonthly July through September, 1987. The length/frequency distribution curve constructed for the 358 dace collected determined Age class 0 to be dace less than 39mm, age classes I and II were indistinguishable because of overlap of fish lengths, and age class III was determined to be dace between 69 and 74mm. Other species encountered in abundance during this …

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 …

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.

Behavioral Feeding Specialization In Pinaroloxias Inornata, The “Darwin's Finch” Of Cocos Island, Costa Rica, Tracey K. Werner, Thomas W. Sherry

Dartmouth Scholarship

As a population, Cocos Finches exhibit a broad range of feeding behaviors spanning those of several families of birds on the mainland, while individuals feed as specialists year-round. Although this extreme intraspecific variability occurs as predicted in a tropical oceanic island environment, these specializations challenge contemporary ecological theory in that they are not attributable to individual differences in age, sex, gross morphology, or opportunistic exploitation of patchy resources. Instead, they appear to originate and be maintained behaviorally, possibly via observational learning. This phenomenon adds another direction to the evolutionary radiation of the Darwin's Finches and underscores the necessity for detailed …

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

Fisheries Management Papers

The Cockburn Sound professional fishery has seen a rapid increase in fishing effort in recent years. In response to this Cockburn Sound has been declared to be a restricted area for commercial fishing pending the introduction of long term management measures. Interim endorsements have therefore been issued for commercial fishing within Cockburn Sound.

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 …

The Esperance Rock Lobster Working Group Interim Report By The Chairman Mr. A. Pallot To The Western Australia Fishing Industry., A. Pallot

Fisheries Management Papers

In July 1985 the Minister for Fisheries released a discussion paper titled "Arrangements for entry to all fisheries off and along the Western Australian coast" for consideration by all members of the fishing industry. The Australian Fishing Industry Council (W.A. Branch), now the Western Australian Fishing Industry Council (Inc), responded to the discussion paper in March 1986. The following were included in the Council's recommendations: 1. The rock lobster fishery near Esperance be a limited entry fishery. 2. The bench mark date for determining access by April 30, 1985. 3. that the Minister for fisheries establish a representative Government/Industry Working …

The Report Of The Fish Farming Legislative Review Committee., P. Rogers

Fisheries Management Papers

In 1975, amendments to the Fisheries Act provided for the licensing and control of commercial fish farming activities and , for specific declared species, further controls on their processing and marketing. To date, marron has been the only species to be declared a "farm fish". During the last decade, much of the State's aquaculture impetus has focused on marron although more recently greater attention has been directed towards trout, yabbies and freshwater aquarium fish species. On November 19, 1984, the Marron Growers Association of Western Australia (Inc) wrote to the Minister for Fisheries and Wildlife, seeding a general review of …

The Report Of The Southern Western Australian Shark Working Group., P. Millington

Fisheries Management Papers

The southern Western Australian Shark Working Group was formed to investigate the southern shark fishery and advise the Minister for Fisheries on options for future management. Membership comprised six fishermen from regional professional fishermen's associations and two Fisheries Department officers. The Working Group considered that each shark fisherman obtaining an entitlement should then be restricted in the length of fishing gear he can use and the number of months he can fish. The individual's time and gear entitlement would be approximately that length of gear being used and time spent fishing in a period shortly before the bench mark date. …

Reproductive Wastage In Sheep, R W. Kelly

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

The average lambing performance of Western Australia's ewe flock fluctuates between 60 and 70 per cent. Although this level of performance and variation between years is important for the sheep industry, individual farmers are more concerned about performance of their own flocks.

Figure shows the range in lambing performances that exist between farms in this State in 1983-84. The seriously poor performance of many flocks is apparentm - 28 percent of farms had less than 60 per cent lambing. By contrast, 24 farms had performances better than 100 per cent. The reasons for the large differences between farms ( and …
