  1. Are farmed salmon more prone to risk than wild salmon? Susceptibility of juvenile farm, hybrid and wild Atlantic salmon Salmo salar L. to an artificial predator

    Contributor(s):: Solberg, M. F., Zhang, ZhiWei, Glover, K. A.

    Offspring of farmed Atlantic salmon have been documented to display lower survival than the offspring of wild salmon in the wild. It has been suggested that reduced survival of farmed salmon offspring in the wild could, in part, be explained by increased susceptibility to predation through...

  2. First links between self-feeding behaviour and personality traits in European seabass, Dicentrarchus labrax

    Contributor(s):: Ferrari, S., Benhaim, D., Colchen, T., Chatain, B., Begout, M. L.

    Most studies carried out with seabass under self-feeding conditions report an intriguing social structure that is built around the device and the food dispenser with three coexisting triggering categories: high-triggering (HT), low-triggering (LT) and zero-triggering (ZT) fish. However, neither...

  3. The Cayman Turtle Farm: why we can't have our green turtle and eat it too

    Contributor(s):: D'Cruze, N., Alcock, R., Donnelly, M.

    The Cayman Turtle Farm (CTF) is the only facility in the world that commercially produces green sea turtles ( Chelonia mydas) for human consumption. The CTF has operated at a significant financial loss for much of its 45 years history and is maintained by substantial Cayman Island Government...

  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. Whale shark tourism in Ningaloo Marine Park, Australia

    Contributor(s):: Davis, D.

    Surveys conducted among whale shark tourists in Ningaloo Marine Park, off the coast of Western Australia, yielded 464 responses in 1995 and 376 in 1996. Multivariate analysis of variance (MANOVA) is used to compare attitudes towards management questions relating to human-to-shark separation...

  6. Less common house pets

    Contributor(s):: Chomel, B. B., Schlossberg, D.

    This chapter focuses on the major health threats associated with exposure of humans to less common house pets. The viral, bacterial, parasitic and mycotic zoonoses transmitted by pet rabbits, rodents, reptiles, amphibians, ornamental aquarium fish, ferrets, bats and nonhuman primates are...

  7. Risk assessment of genetically modified food and neoliberalism: an argument for democratizing the regulatory review protocol of the Food and Drug Administration

    Contributor(s):: Meghani, Z.

    The primary responsibility of the US Food and Drug Administration (FDA) is to protect public health by ensuring the safety of the food supply. To that end, it sometimes conducts risk assessments of novel food products, such as genetically modified (GM) food. The FDA describes its regulatory...

  8. The leading Canadian NGOs' discourse on fish farming: from ecocentric intuitions to biocentric solutions

    Contributor(s):: Pigeon, L. E., Letourneau, L.

    The development of the aquaculture industry in Canada has triggered a conflict of a scope never seen before. As stated in Young and Matthews' The Aquaculture Controversy, this debate has "mushroomed over the past several decades to become one of the most bitter and stubborn face-offs over...

  9. Dolphin Therapy: The Playful Way to Work toward the Next Step

    Contributor(s):: Wermer, Maaike

  10. 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...

  11. 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...

  12. 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...

  13. 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...

  14. 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...

  15. 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...

  16. 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...

  17. Octopus senescence: the beginning of the end

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

    Senescence is a normal stage of an octopus's life cycle that often occurs before death. Some of the following symptoms typify it: lack of feeding, retraction of skin around the eyes, uncoordinated movement, increased undirected activity, and white unhealing lesions on the body. There is inter-...

  18. 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...

  19. Physiological responses in wild broodstocks of the Caspian Kutum (Rutilus frisii kutum) subjected to transportation stress

    Contributor(s):: Nikoo, M., Falahatkar, B.

  20. The use of positive reinforcement in training zebra sharks ( Stegostoma fasciatum)

    Contributor(s):: Marranzino, A.

    Positive reinforcement training (PRT) was used on 4 adult zebra sharks, Stegostoma fasciatum, housed at the Downtown Aquarium, Denver, to determine the ability of zebra sharks to become desensitized to various stimuli associated with veterinary procedures. One male and 3 female sharks were...
