Abalone Aquaculture In Western Australia : Policy Guideline., Fisheries Western Australia.

Fisheries management papers

Experimental or commercial abalone aquaculture is being pursued in many countries with major investments in The United States, Taiwan, China and Korea as well as in Australia. The combined total abalone aquaculture production from China and Taiwan was reported to be in the order of 2,000 tonnes and continues to rise. As cultured ‘cocktail’ abalone are below the legal harvest size of wild abalone, there will be limited competition between aquaculture and the wild fisheries.

A Preliminary Investigation Of The Construct Of Psychopathic Personality (Psychopathy) In Chimpanzees (Pan Troglodytes), Scott O. Lilienfeld, Jonathan Gershon, Marshall Duke, Lori Marino, Frans B. M. De Waal

Sentience Collection

Although the construct of psychopathy has received considerable attention in humans, its relevance to other animals is largely unknown. We developed a measure of psychopathy for use in chimpanzees (Pan troglodytes), the Chimpanzee Psychopathy Measure (CPM), and asked 6 raters to complete this index on 34 chimpanzees. The CPM (a) demonstrated satisfactory interrater reliability and internal consistency; (b) exhibited marginally significant sex differences (males > females); (c) correlated positively with measures of extraversion, agreeableness, and observational ratings of agonism, sexual activity, daring behaviors, teasing, silent bluff displays, and temper tantrums, and negatively with observational ratings of generosity; and (d) demonstrated incremental …

Scale-Model Comprehension By Chimpanzees (Pan Troglodytes), Valerie A. Kuhlmeier, Sarah T. Boysen, Kimberly L. Mukobi

Sentience Collection

The ability of chimpanzees (Pan troglodytes) to recognize the correspondence between a scale model and its real-world referent was examined. In Experiments 1 and 2, an adult female and a young adult male watched as an experimenter hid a miniature model food in 1 of 4 sites in a scale model. Then, the chimpanzees were given the opportunity to find the real food item that had been hidden in the analogous location in the real room. The female performed significantly above chance, whereas the male performed at chance level. Experiments 3 and 4 tested 5 adult and 2 adolescent chimpanzees …

Overall Animal Welfare Assessment Reviewed. Part 1: Is It Possible?, M.B.M. Bracke, B. M. Spruijt, J.H.M. Metz

Assessment of Animal Welfare Collection

Several authors have concluded that scientists should not attempt to perform overall animal welfare assessment (OWA). They argue that scientists have continued to fail to make progress in this area and that value judgements are inherently involved in OWA for which science cannot provide answers. We take a more positive attitude toward OWA and argue that scientists should avoid creating a self-fulfilling prophecy. OWA is necessary for making actual moral and political decisions. Science has already accumulated much relevant information about welfare and this information should be applied in decision making.

The task of OW A is to assess welfare …

Overall Animal Welfare Reviewed. Part 2: Assessment Tables And Schemes, M.B.M. Bracke, J.H.M. Metz, B. M. Spruijt

Assessment of Animal Welfare Collection

In the scientific literature several attempts have been made to systematically assess the overall welfare-status of animals in relation to housing and management. This paper reviews assessment tables and schemes that have been constructed to this end. These tables and schemes have a tabular format that allows an assessment of housing systems using a list of welfare-relevant attributes (properties of the housing system). Rather than identifying deficits, the focus of this review is on finding positive recommendations for the purpose of developing a method for overall welfare assessment (OWA) on a scientific basis. The main recommendation is to use the …

Overall Animal Welfare Reviewed. Part 3: Welfare Assessment Based On Needs And Supported By Expert Opinion, M.B.M. Bracke, B. M. Spruijt, J.H.M. Metz

Assessment of Animal Welfare Collection

Welfare concerns what matters to animals from their point of view. What matters to animals is their state of need. Satisfaction and frustration of needs are associated with emotional states, the subjective experience of which directly determines the welfare status of an animal. Because emotional states are difficult to assess, overall welfare assessment (OWA) is best approached as an assessment of needs.

For actual OW A a list of needs must be formulated. Different authors have formulated different lists. From these lists a concept need-list was constructed. For validation the needs-based approach for OWA was discussed in interviews with experts …

A Comparative Gene Map Of The Horse (Equus Caballus), Alexandre R. Caetano, Yow-Ling Shiue, Leslie A. Lyons, Stephen J. O'Brien, Thomas F. Laughlin, Ann T. Bowling, James D. Murray

Biology Faculty Articles

A comparative gene map of the horse genome composed of 127 loci was assembled based on the new assignment of 68 equine type I loci and on data published previously. PCR primers based on consensus gene sequences conserved across mammalian species were used to amplify markers for assigning 68 equine type I loci to 27 horse synteny groups established previously with a horse-mouse somatic cell hybrid panel (SCHP, UC Davis). This increased the number of coding genes mapped to the horse genome by over 2-fold and allowed refinements of the comparative mapping data available for this species. In conjunction with …

Nebraska Bird Review

This season, partly due to the departure of my co-writer Joel Jorgensen and partly due to mental aging, I have shortened the species accounts by including only data that add to our current knowledge base. I will not routinely list early and late dates and peak counts for each species unless they are significant; readers should refer to past issues of NBR for guidelines as to what are early or late dates and high counts. Observers are, however, urged to report early and late dates and high counts of all migrant species; it is difficult to know if a sighting …

Monogenic Control Of Iris Coloration In The January Tetra (Hemigrammus Hyanuary Characidae), Jack Frankel

Department of Biology Faculty Publications

The January tetra (Hemigrammus hyanuary Durbin) exhibits two eye color phenotypes. These have a silver iris, which is characteristic of the species, and a green color variant. Segregation patterns observed in the progenies from 12 different crosses support an hypothesis for the monogenic inheritance of iris coloration in this species.

1998 (Tenth) Report Of The Nou Records Committee, Mark A. Brogie

Nebraska Bird Review

The functions and methods of the NOU Records Committee are described in its bylaws (NOU Records Committee 1986). The committee's purpose is to provide a procedure for documenting unusual bird sightings and to establish a list of all documented birds for Nebraska. THE OFFICIAL LIST OF THE BIRDS OF NEBRASKA was first published in 1988 (NOU Records Committee 1988) and has been appended eight times (Mollhoff 1989, Grenon 1990, 1991, Gubanyi 1996a, 1996b, 1996c, Brogie 1997, Brogie 1998). An update of THE OFFICIAL LIST OF THE BIRDS OF NEBRASKA was last published in 1997 (NOU Records Committee 1997).

Light Backscatter Of Milk Products For Transition Sensing Using Optical Fibers, Frederick A. Payne, Czarena L. Crofcheck, Sue E. Nokes, Klat C. Kang

Biosystems and Agricultural Engineering Faculty Publications

Transition sensors are needed, particularly in the dairy industry, for detecting transitions in pipe flow systems from product-to-water or product-to-product (such as from chocolate to vanilla ice cream mix). Transition information is used to automatically sequence valves to minimize product waste. Optical fibers were used to measure light backscatter between 400 and 950 nm as a function of milk concentration in water and milkfat concentration in milk. The normalized response (100% for product and 0% for water) as a function of product concentration in water was approximately logarithmic for skim milk between 400 and 900 nm and approximately linear for …

Preliminary Observations Of Barndoor Skates (Raja Laevis) On Georges Bank, Todd Gedamke, William D. Dupaul

Reports

An article published in Science magazine last year (Casey and Myers, 1998) has generated increased concern about the status of the barndoor skate (Raja laevis) in the North Atlantic. Very little information is available and a better understanding of the barndoor's life history, distribution and abundance is necessary for proper management. This document serves to provide preliminary data from an ongoing study that may aid in the current understanding of the barndoor skate population ..

Cartilage Regeneration On A Large Articular Surface Facilitated By Stress Shielding, Charles L. Mcdowell, Jennifer S. Wayne, Robert Tuten, Hunter H. Mcguire Jr.

Virginia Journal of Science

An animal model for the study of articular cartilage regeneration in-vivo facilitated by stress-shielding is introduced. The object of the model is to test the hypothesis that some form of cartilaginous tissue will grow upon a large joint surface in vivo with the joint in normal motion. The model utilizes the known capability of immature cells to differentiate. The source of cells is bleeding subchondral bone. In addition, the model provides a mechanically shielded environment in which cell differentiation and maturation can occur. The study showed that a substantial amount of tissue will grow in the animal model only when …
