A Review Of Ministerial Policy Guidelines For Rock Lobster Processing In Western Australia From The Working Group Appointed By The Minister For Fisheries And Chaired By Peter Rich, Peter Rich
Fisheries management papers
The rock lobster processing industry in Western Australia has a long history of management. Whilst management of the industry through the Fisheries Department has obviously been successful in helping to build the rock lobster industry into one of the State's major export industries, this approach is not without problems. With the introduction of the Fisheries Management Act 1994, the Minister for Fisheries deemed it appropriate to appoint an expert group to review the existing regulation of the rock lobster processing sector, draft the necessary guidelines to assist the Executive Director of the Fisheries Department make decisions on rock lobster processing …
Evaluation Of Animal Welfare By The Self-Expression Of An Anxiety State, M. P. Carey, J. P. Fry
Evaluation Of Animal Welfare By The Self-Expression Of An Anxiety State, M. P. Carey, J. P. Fry
Assessment of Animal Welfare Collection
Although mental well-being has long been accepted as an important aspect of animal welfare, the subjective feelings of farm or laboratory animals are regarded as lying beyond the scope of scientific enquiry. We now report that pharmacological conditioning of pigs with a drug, pentylenetetrazole, known to induce anxiety in man, permits investigation of the presence or absence of this psychological state during exposure to a variety of environmental stimuli encountered during normal husbandry. Such pharmacological conditioning therefore provides a valuable means to assess and improve elements of animal welfare and should be applicable to other species that show operant behaviour.
The Impact Of The New Management Package On Smaller Operators In The Western Rock Lobster Fishery, Ross Gould
The Impact Of The New Management Package On Smaller Operators In The Western Rock Lobster Fishery, Ross Gould
Fisheries management papers
For the 1993/94 western rock lobster fishing season several new management strategies were introduced. The objective of the changes to the management package was to protect the rock lobster fishery. It was also to provide sufficient breeding stock to ensure viability of the industry. The most significant new measure was a temporary (two seasons) 18 percent pot reduction. Other changes were also made. There were considered sound reasons for reviewing and changing the previous management package. Despite this, some fishermen were critical of the new management package, and claimed that it unfairly disadvantaged smaller operators. Against this background, the Department …
Conflict And Cooperation: Sociobiological Principles And The Behaviour Of Pigs, David Fraser, D. L. Kramer, E. A. Pajor, D. M. Weary
Conflict And Cooperation: Sociobiological Principles And The Behaviour Of Pigs, David Fraser, D. L. Kramer, E. A. Pajor, D. M. Weary
Sociobiology Collection
The pig provides many examples of how principles of behavioural ecology and sociobiology can lead to insights into farm animal behaviour. According to parent-offspring conflict theory, parents should tend to give a level of parental investment somewhat below that solicited by the young. When closely confined during lactation, sows can do little to limit the amount of contact with the piglets, and the young stimulate a prolonged, high level of lactation. Certain alternative housing systems allow the sow to limit the stimulation she receives, and the resulting reduction in lactation can actually be advantageous to both parties. Communal care of …
West Coast Rock Lobster Fishery Management Plan 1995 - Draft For Public Comment, M. Moran
West Coast Rock Lobster Fishery Management Plan 1995 - Draft For Public Comment, M. Moran
Fisheries management papers
The purpose of this management plan is to regulate fishing for rock lobsters (Family Palimuridae) in waters off the west coast of Western Australia such that the breeding stock of rock lobsters is maintained at a level known to have generated adequate recruitment of young lobsters in the past. This management plan does not constitute a change in the management arrangements for the rock lobster fishery. It essentially replaces the West Coast Rock Lobster Limited Entry Fishery Notice 1993 made under the Fisheries Act 1905 and makes the required changes to wording and structure necessitated by the proclamation of the …
Bag And Size Limit Fishing Regulations From Around Australia - Current Information As At 1 July, 1995 - Third Australasian Fisheries Managers Conference, Rottnest Island, Wa, F. B. Prokop
Fisheries management papers
This paper was originally prepared for the first National Fisheries Managers Conference in 1993. It is now updated and includes the current bag and size limits from around Australia as at 1 July, 1995. It is fairly obvious from this paper that there is a need for more cooperation between the states, particularly for species which have wide distributions. However, regional solutions can be a good approach for specific management needs, while general rules can be made more consistent in a number of cases.

The Recreational Fishing Advisory Committee (RFAC) approved holding this translocation seminar to air the translocation of fish for recreational enhancement in a public forum. This forum will identify issues including establishing common ground between the variety of interest groups which are represented. Contentious areas which require further investigation and consultation should become apparent, and assist the formulation of appropriate policies on translocation for Western Australia.
Management Of The Northern Demersal Scalefish Fishery, Jane Fowler
Management Of The Northern Demersal Scalefish Fishery, Jane Fowler
Fisheries management papers
In mid 1994, the Fisheries Department of Western Australia announced that it would prepare a discussion paper setting out options for future management of the demersal scalefish fishery off the Kimberley coast. This paper, which was to be the start of a wider consultative process, was also to include options for possible further development of the trap and line fisheries. This paper is only the first step in a process for developing formal long term management arrangements under the new fisheries legislation, the Fish Resources Management Act 1994. Its aim is to provide some background and to present some management …

Report On Future Management Options For The South West Trawl Limited Entry Fishery, South West Trawl Limited Entry Fishery Working Group
Fisheries management papers
As a result of community concern regarding trawling, the current management rules for the South West Trawl Limited Entry Fishery were finalised in February 1989 and the final plan was gazetted in October of that year. However, there was public disquiet about this trawling, and as a result of this disquiet, a research program was initiated by the Fisheries Department with funding received from both the Commonwealth and State Governments. The scientific report, "The impact of trawling for saucer scallops and western king prawns on the benthic communities in coastal waters off south-western Australia" by L J B Laurenson, P …
Management Options (Discussion Paper) For The Shark Bay Snapper Limited Entry Fishery, Shark Bay Snapper Limited Entry Fishery Working Group, Doug Bathgate
Management Options (Discussion Paper) For The Shark Bay Snapper Limited Entry Fishery, Shark Bay Snapper Limited Entry Fishery Working Group, Doug Bathgate
Fisheries management papers
At the Annual Management Meeting of the Shark Bay Snapper Limited Entry Fishery held on 22 July 1994 industry put forward a proposal that supplementary and non-transferable quota that was "lost" to the fishery when a licence holding non-transferable quota was transferred should be retained by the Fisheries Department and leased back to licence holders on an annual basis. As a result of this proposal and the fact that the management arrangements for the fishery are extremely complex and in need of simplification, the Minster for Fisheries approved the establishment of a Working Group to examine the lease-back proposal and …

The Best Available Information - Its Implications For Recreational Fisheries Management, F. B. Prokop
The Best Available Information - Its Implications For Recreational Fisheries Management, F. B. Prokop
Fisheries management papers
Workshop at Second National Fisheries Managers Conference, Bribie Island, Queensland, October 18, 1994. Recreational fisheries management is one of the growth areas in Australian fisheries. The Australian Society for Fish Biology Workshop topic for its 1994 Conference was Recreational Fishing - What's the Catch. It was acknowledged at the ASFB conference that there were generally poor levels of information and for the lower value commercial and recreational fisheries there may be no way to gather definitive research data for the foreseeable future. However, in even the high profile fisheries, public perceptions, attitudes, and political will do not allow for the …
The Challenge And Opportunity Of Recovering Wolf Populations, L. David Mech
The Challenge And Opportunity Of Recovering Wolf Populations, L. David Mech
USGS Northern Prairie Wildlife Research Center
The gray wolf once inhabited a wide variety of habitats throughout most of the northern hemisphere north of 20°N latitude. Because the animal preyed on livestock and competed with humans for wild prey, it was extirpated from much of its range outside of wilderness areas. Environmental awareness in the late 1960s brought for the wolf legal protection, increased research, and favorable media coverage. The species has increased in both Europe and North America, is beginning to reoccupy semiwilderness and agricultural land, and is causing increased damage to livestock. Because of the wolfs high reproductive rate and long dispersal tendencies, the …

Indicating Acts During Counting By A Chimpanzee (Pan Troglodytes), Sarah T. Boysen, Gary G. Berntson, Traci A. Shreyer, Michelle B. Hannan
Sentience Collection
A chimpanzee (Pan troglodytes) experienced in counting arrays of 0-7 items and trained for comprehension of number symbols, spontaneously displayed a variety of indicating acts (e.g., pointing, touching, and rearranging items) during counting. Twenty-five sessions were videotaped, and all trials were evaluated for the relations among number of items presented, number of indicating acts displayed, and the Arabic number selected to represent the array. Significant correlations included the relations between number of items and the cardinal number selected by the animal, between the number of items and indicating acts displayed by the chimpanzee, and between the number of indicating acts …

Regional Variation In Temperature Humidity Index For Poultry Housing, Richard S. Gates, Hanzhong Zhang, Donald G. Colliver, Douglas G. Overhults
Biosystems and Agricultural Engineering Faculty Publications
A building thermal model was used to compute hourly values of temperature humidity index (THI) for a broiler house with and without an evaporative misting system. Hourly summer time weather data for 238 U.S.A. locations covering 30 years were used to develop extreme occurrences of THI. Results were incorporated into a Geographical Information System (GIS) database to create isolines of THI and percentage of hours exceeding a heat stress threshold. Regional variations in misting as a suitable cooling technique are presented in terms of hours reduction in annual heat stress. The technique may be used for assisting in management decisions …

A Ten-Year History Of The Demography And Productivity Of An Arctic Wolf Pack, L. David Mech
A Ten-Year History Of The Demography And Productivity Of An Arctic Wolf Pack, L. David Mech
USGS Northern Prairie Wildlife Research Center
A pack of two to eight adult wolves (Canis lupus arctos) and their pups was observed during ten summers (1986–95) on Ellesmere Island, Northwest Territories, Canada. The author habituated the wolf pack to his presence in the first summer and reinforced the habituation each summer thereafter. The first alpha female produced four to six pups each year between 1986 and 1989. However, her daughter, who succeeded her as the alpha female, produced only one to three pups each year between 1990 and 1992 and in 1994, and apparently did not whelp in 1993 or in 1995. The tenure …
Calling By Domestic Piglets: Reliable Signals Of Need?, Daniel M. Weary, David Fraser
Calling By Domestic Piglets: Reliable Signals Of Need?, Daniel M. Weary, David Fraser
Communication Skills Collection
Two manipulations were performed on domestic piglets to determine whether differences in calling during periods of separation from the mother can indicate differences in need. In both cases, the aim was to manipulate the piglet's need for the sow's attention. In the first manipulation a 'thriving' piglet (i.e. the piglet with the heaviest weight and most rapid weight gain) and a 'non-thriving' one (lightest and slowest weight gain) were selected from each of 15 litters. The two piglets were removed from the sow and litter and recorded for 13 min in separate isolated enclosures. For the second manipulation, two piglets …

Responses To Quantity: Perceptual Versus Cognitive Mechanisms In Chimpanzees (Pan Troglodytes), Sarah T. Boysen, Gary G. Berntson
Sentience Collection
Two chimpanzees were trained to select among 2 different amounts of candy (1-6 items). The task was designed so that selection of either array by the active (selector) chimpanzee resulted in that array being given to the passive (observer) animal, with the remaining (nonselected) array going to the selector. Neither animal was able to select consistently the smaller array, which would reap the larger reward. Rather, both animals preferentially selected the larger array, thereby receiving the smaller number of reinforcers. When Arabic numerals were substituted for the food arrays, however, the selector animal evidenced more optimal performance, immediately selecting the …

Comprehension Of Cause-Effect Relations In A Tool-Using Task By Chimpanzees (Pan Troglodytes), Luca Limongelli, Sarah T. Boysen, Elisabetta Visalberghi
Sentience Collection
Five chimpanzees (Pan troglodytes) were tested to assess their understanding of causality in a tool task. The task consisted of a transparent tube with a trap-hole drilled in its middle. A reward was randomly placed on either side of the hole. Depending on which side the chimpanzee inserted the stick into, the candy was either pushed out of the tube or into the trap. In Experiment 1, the success rate of 2 chimpanzees rose highly above chance, but that of the other subjects did not. Results show that the 2 successful chimpanzees selected the correct side for insertion beforehand. Experiment …
