  1. 'Animal Ethics Dilemma': an interactive learning tool for university and professional training

    Contributor(s):: Hanlon, A. J., Algers, A., Dich, T., Hansen, T., Loor, H., Sandoe, P.

    'Animal Ethics Dilemma' is a freely available computer-supported learning tool (www.animalethicsdilemma.net or www.aedilemma.net) which has been developed primarily for veterinary undergraduates but is applicable also to students in other fields of animal science. The objectives of the computer...

  2. A "how-to" guide for designing judgment bias studies to assess captive animal welfare

    Contributor(s):: Bethell, E. J.

    Robust methods to assess nonhuman animal emotion are essential for ensuring good welfare in captivity. Cognitive bias measures such as the judgment bias task have recently emerged as promising tools to assess animal emotion. The simple design and objective response measures make judgment bias...

  3. A survey of the attitudes of stakeholders in the zoo industry towards the husbandry requirements of captive Great Apes

    Contributor(s):: Fernie, A. C., Tribe, A., Murray, P. J., Lisle, A., Phillips, C. J. C.

  4. Activity budgets of captive Cape fur seals ( Arctocephalus pusillus) under a training regime

    Contributor(s):: Wierucka, K., Siemianowska, S., Wozniak, M., Jasnosz, K., Kieliszczyk, M., Kozak, P., Sergiel, A.

    Ethograms and time budgets are crucial for the behavioral assessment of nonhuman animals in zoos, and they serve as references for welfare research. This study was conducted to obtain detailed time budgets of trained Cape fur seals ( Arctocephalus pusillus) in captivity, to evaluate variations of...

  5. Aggression and welfare in a common aquarium fish, the Midas cichlid

    Contributor(s):: Oldfield, R. G.

    Many species of fishes are aggressive when placed in small aquaria. Aggression can negatively affect the welfare of those individuals toward whom it is directed. Animals may behave aggressively in order to defend resources such as food, shelter, mates, and offspring. The decision to defend...

  6. Aggressiveness and locomotion activity related to hatching time in Matrinxa, Brycon amazonicus (Spix and Agassiz, 1829)

    Contributor(s):: Souza, E. C. M. de, Silva, J. P. da, Villacorta-Correa, M. A., Carvalho, T. B.

    Since agonistic interaction has been a major obstacle for fish hatchery and represents great economic losses for fish farmers, aggressiveness during the different post-hatching stages of the matrinxa, Brycon amazonicus, is analyzed and compared. Each group of three larvae was observed at six...

  7. An empirical case study examining effectiveness of environmental enrichment in two captive Australian Sea Lions ( Neophoca cinerea )

    Contributor(s):: Smith, B. P., Litchfield, C. A.

    This case study examined the effect of environmental enrichment on the activity budgets of a male and female Australian Sea Lion (Neophoca cinerea) housed together at Adelaide Zoo. Using non-food-related (intrinsic) and food-related (extrinsic) enrichment objects, the study conducted an ABABA...

  8. An ethicist's commentary on keeping aquatic animals in markets

    Contributor(s):: Rollin, B. E.

  9. Animal assisted therapy Part 1: Physical therapy and rehabilitation

    Contributor(s):: Reynolds, A.

  10. Animal welfare and organic aquaculture in open systems

    Contributor(s):: Cottee, S. Y., Petersan, P.

    The principles of organic farming espouse a holistic approach to agriculture that promotes sustainable and harmonious relationships amongst the natural environment, plants and animals, as well as regard for animals' physiological and behavioral needs. However, open aquaculture systems - both...

  11. Animal welfare perspectives on recreational angling. (Special issue: Fish Behaviour and Welfare.)

    Contributor(s):: Cooke, S. J., Sneddon, L. U.

    Fish captured by recreational anglers are often released either voluntarily or because of harvest regulations in a process called "catch-and-release". Catch-and-release angling is thought to be beneficial for the conservation of fish stocks based on the premise that most of the fish that are...

  12. Aquaculture and restocking: implications for conservation and welfare. (Special Issue: Conservation and animal welfare.)

    Contributor(s):: Braithwaite, V. A., Salvanes, A. G. V.

    As the harvesting of fish through commercial fisheries becomes both harder and less economically viable, the world is becoming increasingly dependent on aquaculture to provide fish for human consumption. The closely related activity of stock enhancement, whereby large numbers of fish are reared...

  13. Are animals capable of deception or empathy? Implications for animal consciousness and animal welfare

    Contributor(s):: Kuczaj, S., Tranel, K., Trone, M., Hill, H.

  14. Assessment of different stunning methods and recovery of farmed Atlantic salmon ( Salmo salar ): isoeugenol, nitrogen and three levels of carbon dioxide

    Contributor(s):: Erikson, U.

    Isoeugenol (17 mg AQUI-STM L-1), nitrogen, and three levels of carbon dioxide (low: 70-80, medium: 180-250 and high: >400 mg CO2 L-1) were tested as stunning agents for Atlantic salmon (Salmo salar) fasted for six days. All methods were tested under optimised conditions (starting with rested...

  15. Behavior of a solitary sociable female bottlenose dolphin ( Tursiops truncatus ) off the coast of Kent, southeast England

    Contributor(s):: Eisfeld, S. M., Simmonds, M. P., Stansfield, L. R.

    This article provides a report of the behavior of a solitary sociable dolphin studied on the southeast coast of England in 2007. This is the first study of its kind in which behavior of such a nonhuman animal was systematically studied. By the time of this study, this young female was highly...

  16. Behaviour

    Contributor(s):: Childress, M. J. Jury S. H.

    In this chapter the authors attempt to identify the important constraints on lobster behavioural evolution due to life history, morphology, physiology, habitat, biotic interactions, and most recently human habitat alterations and fishing pressure. The focus is on recent research advances...

  17. Behavioural responses of Argentine coastal dusky dolphins Lagenorhynchus obscurus to a biopsy pole system

    Contributor(s):: Loizaga de Castro, R., Hoelzel, A. R., Crespo, E. A.

  18. Behavioural responses of captive common dolphins Delphinus delphis to a 'Swim-with-Dolphin' programme

    Contributor(s):: Kyngdon, D. J., Minot, E. O., Stafford, K. J.

    We monitored the effects of a `Swim-with-Dolphin' (SWD) programme on the behaviour of three female common dolphins. They were studied from January 1999 to July 1999 at Marineland, Napier, New Zealand. Before, during and after SWD sessions we recorded: (1) the use of a refuge area, (2) the...

  19. Can fish suffer?: perspectives on sentience, pain, fear and stress

    Contributor(s):: Chandroo, K. P., Duncan, I. J. H., Moccia, R. D.

    In contrast to other major forms of livestock agriculture, there is a paucity of scientific information on the welfare of fish raised under intensive aquacultural conditions. This reflects an adherence to the belief that these animals have not evolved the salient biological characteristics that...

  20. Claw removal and feeding ability in the edible crab, Cancer pagurus : implications for fishery practice

    Contributor(s):: Patterson, L., Dick, J. T. A., Elwood, R. W.

    Feeding ability and motivation were assessed in the edible crab, Cancer pagurus, to investigate how the fishery practice of de-clawing may affect live crabs returned to the sea. Crabs were either induced to autotomise one claw, or were only handled, before they were offered food. Initially,...
