Ministerial Policy Guideline No.10: The Abalone Managed Fishery In Western Australia, Department Of Fisheries Wa

Fisheries Administrative Guidelines

The commercial fishing of abalone has been regulated in one form or another since the early 1970s. In the present day, commercial fishing for abalone in Western Australian waters is principally regulated by the Abalone Management Plan 1992 which is taken to have been made, and is in force, under the Fish Resources Management Act 1994 ("the Act").

The regulatory regime established by the Abalone Management Plan 1992 ("the Plan") is based upon the principle that in each year a specific quantity of abalone (often referred to as 'quota') is determined to be the 'allowable catch' for that year. This …

Fisheries Research Report No. 122 - Western Rock Lobster Mail Surveys Of Licensed Recreational Fishers 1986/87 To 1998/99, Roy Melville-Smith, Sonia M. Anderton

Fisheries Research Reports

Information on the catch, effort and fishing characteristics of recreational rock lobster fishers has been collected in Western Australia (WA) since 1986, by an annual mail survey of a randomly selected sample of rock lobster licence holders. Over the period 1986-1999, the number of licensed recreational rock lobster fishers in WA has approximately doubled, from 15,249 (1987/88) to 32,768 (1998/99), and the estimated catch has nearly tripled, from 219 tonnes (1987/88) to 626 tonnes (1998/99). These estimates have not attempted to take into account illegal catches.

Of those who do fish, approximately 65% of recreational rock lobster licence holders exclusively …

Fisheries Management Report No. 4 - Planning For The Further Development Of The Aquaculture And Marine Farming Industry At Jurien Bay, Dave Everall

Fisheries Published Reports

There is a well documented global requirement for some twenty million tonnes of edible sea foods from aquaculture in the next fifteen years. Most of the projected increase in production will need to be from mariculture because of limiting factors on land based aquaculture. At present, approximately 85%of all aquaculture occurs in the Asian region.

Globally, temperate water species have market advantages because of their ability to supply a growing market preference for a firm white fleshed fin fish. Although significant temperate water aquaculture occurs in various countries north of the equator, there are growing environmental concerns surrounding production of …

Methods For The Comparison Of Timing Behavior Applied To The Pink Salmon Fisheries Of Prince William Sound, Alaska, Louis J. Rugolo

OES Theses and Dissertations

Harvest control in salmonid fisheries was examined as a problem in the formulation of regulations which restrict time and area of fishing. An ability to rigorously define and compare the form of the progression of migration across time and between harvest areas was judged fundamental to objective harvest decisions. Identification and evaluation of statistical methods appropriate to the comparison of empirical migratory time densities was performed.

The development of the measure of central tendency (mean date) of the time density as the consistent, unbiased estimator of migratory behavior was given. Practical evidence demonstrated that the mean date was highly resistant …

Computer Simulation Techniques To Assess Bias And Precision In The Roving Creel Survey Estimator, David L. Wade

Biological Sciences Theses & Dissertations

Fisheries scientists use roving creel survey methods to estimate total catch and total effort of recreational fisheries. Bias in the roving creel estimators had been known to the scientific community, but it had not been quantified. I developed a roving-creel-survey computer simulation model to investigate the bias and precision of roving creel estimators, and estimated parameters for the model based on field observations from the blue crab (Callinectes sapidus) fishery of the Chesapeake Bay. The computer model was used to identify bias in roving-creel effort and catch estimators and to demonstrate survey methods that will reduce this bias. …

Recreation Specialization And Preferences Of Utah Anglers, Bruce P. Andersen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purposes of this study were to gain a better understanding of anglers and angler preferences and to examine differences between subgroups of anglers based on level of specialization. Understanding these similarities and differences between user groups will provide valuable input for more effective fisheries management.

A randomized mail survey was sent to resident, adult fishing-license holders in Utah. A 68% response rate yielded 1216 usable returns for data analysis. An analysis of three recreation specialization dimensions (participation, equipment and investment, and lifestyle) and further analysis of participation and investment variables were used to develop a typology of Utah anglers. …

Fisheries Research Report No. 84 - The Marine Open Shelf Environment: Review Of Human Influences, D. A. Hancock

Fisheries Research Reports

For the purpose of this review, the marine environment has been classified into three physical zones - the littoral zone, the open-shelf environment and the coral reef. Since the boundaries are arbitrary, there will inevitably be some overlap, but for this review the subject matter will be related to the area between low water of ordinary spring tides and the edge of the continental shelf; i.e., to a depth varying to 200 metres.

Human influences may have a dual role in affecting the marine environment, firstly in a causative manner and secondly in providing a remedy, in which case the …

A Comparison Of Potential Fishing Methods Associated With Fish Aggregating Devices Off The Northeast Coast Of Puerto Rico, Alan M. Friedlander

OES Theses and Dissertations

Six fish aggregating devices (FADs) were deployed in June and monitored through December 1986. Emphasis was placed on trolling, live-bait handlining and longlining.

There was a significant difference (x2 = 7.815, pCoryphaena hippurus) which made up 64.2% of the catch.

Handlining at night around inshore buoys for one boat yielded 82.7 kg per trip. Pelagic fish comprised 83.9% of the catch, with the majority (81.4%) being kingfish (Scomberomorous cavalla). Catch rates were 50% higher and the species diversity much greater on the FADs versus control during experimental nightfishing, but the difference was not significant.

Longlining resulted in 3.4 …

Fisheries Report No 59 - Potential Fisheries Capability Of The Ord In The Short, Medium And Long Terms, Dr N. Morrissy

Fisheries Research Reports

This report examines the history, future and problems of various methods for development and exploitation of the fisheries resources of the Ord.

The primary resource is the array of native fish and crustacean species, with the possible introduction of other desirable or noxious species being a subject for consideration.

Water resources, supporting these species, are the remaining natural Ord River downstream from the Diversion Dam at Kununurra, the stillwaters of Lake Kununurra and Lake Argyle, and, for aquaculture, the controlled distribution of water supply over the flat land of the irrigation system (Fig. 1). Another recognized resource is the climatic …

Fisheries Report No 50 - Feasibility Trawling Activities In The Great Australian Bight By The Korean Trawlers Dong Ban 91 And Dong Won 509 During The Period 15.11.79 To 12.1.80, Michael H. Walker, Stuart J. Blight, Gerald M. Cliff

Fisheries Research Reports

Four Korean fishing trawlers operated in Western Australian waters, largely on the Northwest shelf, during 1979 under State/Commonwealth feasibility fishing arrangements. Two of these vessels, Dong Bang 91 and Dong Won 509, were given permission by Government, late in 1979, to conduct demersal trawling operations in the Great Australian Bight between longitudes 116°£ to 138°E and outside of 12 miles from shore.

Two observers from the Western Australian Department of Fisheries and Wildlife were involved with monitoring the activities of these vessels at sea in the Bight.

Fisheries Report No 51 - 'Taiyo Maru 71" Demersal Trawling Cruise In Western Australian Coastal Waters South Of 21 S, July-September, 1979, D. I. Heald, M. H. Walker

Fisheries Research Reports

A Japanese demersal trawler, 'Taiyo Maru 771' was given special permission to conduct exploratory trawling in the period 73.7.79-16.9.79 off the Western Australian coast between 21°S Latitude and 35°30'S Latitude, an area which partly overlapped the fishing grounds for the western rock Lobster. The vessel was required to complete a catch, fishing effort and species composition log book issued by the Commonweath Department of Primary Industry. Two Western Australian Department of Fisheries and Wildlife observers on board monitored fishing operations for the entire duration of the cause and undertook research.

Details of each trawl conducted are given and discussed. Catch …

Biology, Reproductive Potential And The Impact Of Fishing Pressure On The Bluegill Fishery Of Pelican Lake, Uintah County, Utah, Bob D. Burdick

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Certain aspects of the biology of two species of fish, bluegill (Lepomis macrochirus) and largemouth bass (Micropterus salmoides), and the assessment of fishing pressure upon the sport fishery of Pelican Lake, Uintah County, Utah, a 680 ha warmwater lake, were studied between April 1, 1976 and June 30, 1978. The growth rate of bluegills (sexes combined) was fairly rapid; the mean back-calculated total lengths from ages one through nine were 55, 112, 166, 194, 211, 229, 245, 256 and 259 mm. The growth of largemouth bass was 104, 194, 271, 316, 350, 405 and 416 mm …

Physiological Response To Hooking Stress In Largemouth Bass (Micropterus Salmoides), A. Wayne Gustaveson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Recent concern about large initial and delayed mortalities resulting from tournament angling for largemouth bass has indicated that it would be desirable to further evaluate the fate of fish that are released after being captured by angling. This study was designed to evaluate sublethal physiological disruptions caused by hooking stress after largemouth bass were played under standardized conditions (0-5 minutes) and to estimate the time needed for recovery of the homeostatic mechanisms (to 72 hours). Blood lactate was used as a measure of metabolic fatigue; plasma osmolality and chloride measurements were used to evaluate osmoregulatory disturbances and gill ion-exchange; and …

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 …

Shellfish Resources Of Washington, Robert Grant Levens

Graduate Student Research Papers

This paper will explore the salt water shellfish resources of Washington State. Particular emphasis will be placed upon the Pacific and Olympia Oysters, the Dungeness Crab, the research being done at Quilcene, and the lesser varieties of shellfish, including shrimp and the hardshell species of clams. The latter includes the littleneck, butter, Manila, and geoduc clams. A major emphasis will be the commercial importance of the shellfish, but the sportsman and the expanding role of Washington as a summer recreation area will not be overlooked.
