  1. Cortisol levels in dolphin Tursiops truncatus interactive programs linked to humanNiveles de cortisol en delfines Tursiops truncatus vinculados a programas interactivos con humanos

    Contributor(s):: Sanchez Okrucky, R., Morales Vela, B.

    Understanding the physiological changes in animals during physical activity to improve animal welfare has become increasingly important in animal collections that remain under human care. To date, the effect of interactive programs on dolphins under human care has not been evaluated, for that...

  2. Public Knowledge, Attitudes, and Behavior towards Sharks and Shark Conservation

    Contributor(s):: Jason O'Bryhim

    Many species of shark are in danger of overexploitation and could possibly be facing  extinction. Sharks have been around for over 400 million years but recent declines that  threaten their existence can be traced back to the current consumptive uses brought on by  humans. If...

  3. Determining the effects of duration and recency of exposure to environmental enrichment

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

    Experience can help animals adapt their behaviour to fit the environment or conditions that they find themselves in. Understanding how and when experience affects behaviour is important for the animals we rear in captivity. This is particularly true when we rear animals with the intent of...

  4. Re-Homing Exotic Species - A Pilot Program to Prevent Release of Exotic Aquatic Pet Species

    Contributor(s):: Andrew M. Lazur, Ruth Hanessian

    An educational poster program designed to inform pet owners of the dangers of releasing exotic species and provide a re-homing mechanism was evaluated as a means to reduce unwanted environmental releases. The poster provided a URL to the program partners' Web site, which listed participating...

  5. 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...

  6. Feeding behavior and the effect of photoperiod on the performance and hematological parameters of the pacama catfish ( Lophiosilurus alexandri)

    Contributor(s):: Kitagawa, A. T., Costa, L. S., Paulino, R. R., Luz, R. K., Rosa, P. V., Guerra-Santos, B., Fortes-Silva, R.

    The aim of this study was to evaluate the rhythms of feeding and locomotor activity, the ability to synchronize to a fixed feeding time, and the influence of photoperiod on the growth parameters, feed intake and hematological parameters of a recently introduced fish in freshwater Brazilian...

  7. 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...

  8. Opportunities for Public Aquariums to Increase the Sustainability of the Aquatic Animal Trade

    Contributor(s):: Michael F. Tlusty, Andrew L. Rhyne, Les Kaufman, Michael Hutchins, Gordon McGregor Reid, Chris Andrews, Paul Boyle, Jay Hemdal, Frazer McGilvray, Scott Dowd

    The global aquatic pet trade encompasses a wide diversity of freshwater and marine organisms. While relying on a continual supply of healthy, vibrant aquatic animals, few sustainability initiatives exist within this sector. Public aquariums overlap this industry by acquiring many of the same...

  9. Sea no evil: Sabrina Imbler at TEDxBrownU

    Contributor(s):: Sabrina Imbler

    Sabrina has a passion for fish and believes in taking care of them properly. She shares valuable information about fish, their lifestyle, her own experiences, and the magic of the sea in her talk on the underwater creatures. Sabrina is a sophomore at Brown University concentrating in English...

  10. Aquarium Fish Medicine

    Contributor(s):: Candace J. Carter, Mary Ann Nieves

    The keeping of ornamental fish may be the most popular animal-oriented hobby in the United States. One household in every three owns and cares for some type of pet fish. In 1985, approximately $200 million was spent on aquarium fish retail sales. An additional $289 million was spent on aquarium...

  11. 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...

  12. 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...

  13. 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...

  14. 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...

  15. 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...

  16. Fish in aquariums for aesthetically enhancing public spaces (AAEPS): an incipient welfare issue?

    Contributor(s):: Soo, P., Todd, P. A.

    In Disney/Pixar's phenomenally popular animated film Finding Nemo (Stanton, 2003), one of the central themes of fish welfare was highlighted when the moorish idol, Gill, commented, "Fish aren't meant to be kept in a box, kid. It does things to you." The notion that fish might have the capacity to...

  17. Interspecific evaluation of octopus escape behavior

    Contributor(s):: Wood, J. B., Anderson, R. C.

    The well-known ability of octopuses to escape enclosures is a behavior that can be fatal and, therefore, is an animal welfare issue. This study obtained survey data from 38 participants - primarily scientists and public aquarists who work with octopuses - on 25 described species of octopus. The...

  18. Investigating fear in rainbow trout ( Oncorhynchus mykiss ) using the conditioned-suppression paradigm

    Contributor(s):: Yue, S., Duncan, I. J. H., Moccia, R. D.

    Trout learned the operant task of pendulum-pressing for a food-reward in a mean of 4.3 sessions lasting 1 hr. In a separate phase, fish also learned - through classical conditioning - to associate a neutral light cue with an aversive stimulus. When again allowed to pendulum-press for food, after...

  19. Octopuses ( Enteroctopus dofleini ) recognize individual humans

    Contributor(s):: Anderson, R. C., Mather, J. A., Monette, M. Q., Zimsen, S. R. M.

    This study exposed 8 Enteroctopus dofleini separately to 2 unfamiliar individual humans over a 2-week period under differing circumstances. One person consistently fed the octopuses and the other touched them with a bristly stick. Each human recorded octopus body patterns, behaviors, and...
