  1. Using self-selection to evaluate the acceptance of a new diet formulation by farmed fish

    Contributor(s):: Carlberg, H., Cheng, Ken, Lundh, T., Brannas, E.

    The evaluation of new diet composition is commonly achieved by performing time-consuming growth trials, which may negatively impact the welfare of a large number of fish if the feed is not accepted. Instead, the fish's behavioural responses to a new diet composition can be used as a first step in...

  2. Cuttlefish in captivity: an investigation into housing and husbandry for improving welfare

    Contributor(s):: Tonkins, B. M., Tyers, A. M., Cooke, G. M.

    The European cuttlefish ( Sepia officinalis) is often kept in public aquaria, is becoming more common in aquaculture, and is also the most frequently used cephalopod in European research. Since 1st January 2013, all cephalopods ( Mollusca) have been protected under UK/EU law (A(SP)A 1986,...

  3. Consistent individual differences in the behavioural responsiveness of adult male cuttlefish ( Sepia officinalis)

    Contributor(s):: Carere, C., Grignani, G., Bonanni, R., Gala, M. della, Carlini, A., Angeletti, D., Cimmaruta, R., Nascetti, G., Mather, J. A.

    Consistent individual differences in clusters of behaviour (animal personalities) are being increasingly recognized by researchers of different disciplines, but studies on invertebrates are still scanty. In order to test for the presence of personality-like individual profiles we assessed the...

  4. Survival of bottlenose dolphin ( Tursiops sp.) calves at a wild dolphin provisioning program, Tangalooma, Australia

    Contributor(s):: Neil, D. T., Holmes, B. J.

    Mortality of calves born to provisioned mothers is identified in the literature as an issue of concern in dolphin provisioning programs. Wild dolphin provisioning at Tangalooma, Moreton Island, Australia has been occurring since 1992. Each evening, up to eight dolphins are provided with fish in a...

  5. 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...

  6. 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...

  7. Effects of pool size on free-choice selections by Atlantic bottlenosed dolphins at one zoo facility

    Contributor(s):: Shyan, M. R., Merritt, D., Kohlmeier, N. M., Barton, K., Tenge, J.

    Dolphin pool design often derives from the concept that cetaceans are ocean based and ipso facto should live in open, deep, watery spaces. This emotionally appealing rationale is not data driven. Researchers report that in the wild, some populations of Atlantic bottlenosed dolphins Tursiops...

  8. "Gift giving" by wild bottle-nose dolphins (Tursiops sp.) to humans at a wild dolphin provisioning program, Tangalooma, Australia

    Contributor(s):: Holmes, B. J., Neil, D. T.

  9. Salivary cortisol in captive dolphins (Tursiops truncatus): a non-invasive technique

    Contributor(s):: Pedernera-Romano, C., Valdez, R. A., Singh, S., Chiappa, X., Romano, M. C., Galindo, F.

  10. The Canadian harp seal hunt: observations on the effectiveness of procedures to avoid poor animal welfare outcomes

    Contributor(s):: Daoust, P. Y., Caraguel, C.

  11. Conflict and reconciliation behavior trends of the bottlenose dolphin ( Tursiops truncatus )

    Contributor(s):: Holobinko, A., Waring, G. H.

    Wild bottlenose dolphin (Tursiops truncatus) populations display societal structures characterized by numerous and frequent changes in group composition, complex social relationships, and high levels of cooperation, attributes also observed in human and nonhuman primate cultures. Maintaining...

  12. Latitudinal variation in diet and patterns of human interaction in the marine otter

    Contributor(s):: Mangel, J. C., Whitty, T., Medina-Vogel, G., Alfaro-Shigueto, J., Caceres, C., Godley, B. J.

    The marine otter (Lontra felina) inhabits patches of rocky coastline from central Peru to southern Chile and is classified as Endangered by the IUCN. Given the limited information available about the species, we set out to assess marine otter diet with a view to detecting latitudinal differences,...

  13. 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...

  14. Behavioural responses of juvenile steller sea lions to abdominal surgery: developing an assessment of post-operative pain

    Contributor(s):: Walker, K. A., Horning, M., Mellish, J. A. E., Weary, D. M.

    Marking and tracking of marine mammals is required to gain a better understanding of life history traits; however, some marking procedures used are likely painful. Recent technological advances include intra-abdominally implanted archival telemetry devices for the life-long monitoring of...

  15. Review of wallowing in pigs: description of the behaviour and its motivational basis

    Contributor(s):: Bracke, M. B. M.

    Wallowing, i.e. coating the body surface with mud, is a natural behaviour of pigs, commonly observed in feral pigs and wild boar, but rarely provided for in current housing systems for domestic pigs. Furthermore, in welfare science the subject has not been receiving much attention. This paper...

  16. Medieval and early modern whaling in Portugal

    Contributor(s):: Brito, C.

    Mainland Portugal is not renowned for having been a whaling nation of significance. However, preliminary studies have brought to light enough historical references to suggest that whaling occurred from at least the 13th century, and the present work identifies 38 historical sources documenting...

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

    Contributor(s):: Reynolds, A.

  18. Effects of the interaction with dolphins on physical and mental conditions of the elderly

    Contributor(s):: Akiyama, J., Sugimoto, K., Ohta, M.

    The effects of animal-assisted therapy (AAT) on the physical and physiological health of old people have been well known. In general, dogs, cats and small animals have been used at the AAT for seniors. In this study we tried to clarify physical and mental effects of the interactions of old people...

  19. Dolphin therapy

    Contributor(s):: Gouva, E., Ergolavou, A., Paschos, I., Perdikaris, C., Nathanailides, C., Damigou, N., Athanasopoulou, F.

    Dolphin therapy emerged during the 1950s. The work of Dr. John Lilly played an important role, since he investigated the impact of dolphins on disabled people. From 1978 onwards, the therapeutic aid of dolphins was further advanced, especially after the success of Dr Davis Nathanson with...

  20. Behavioural responses of juvenile Steller sea lions to hot-iron branding

    Contributor(s):: Walker, K. A., Mellish, J. A. E., Weary, D. M.

    Here we present the first data showing the post-branding behavioural responses in a marine mammal. Eleven captive juvenile Steller sea lions (Eumetopias jubatus) were observed for 3 days before and 3 days after hot-iron branding. Four of six monitored behaviours changed significantly after...
