  1. Australian and New Zealand Veterinary Students’ Ranking of Issues in Aquatic Animal Welfare and Ethics

    Contributor(s):: Lloyd, Janice K. F., Collins, Teresa, Cornish, Amelia R., Degeling, Christopher, Fawcett, Anne, Fisher, Andrew D., Freire, Rafael, Hazel, Susan J., Hood, Jennifer, Johnson, Jane, Phillips, Clive J. C., Stafford, Kevin J., Tzioumis, Vicky, McGreevy, Paul D.

    The welfare of aquatic animals is receiving increasing attention around the world, and this should be reflected in the veterinary curricular. Veterinary students in Australia and New Zealand ranked the importance of five pre-selected topics on aquatic animal welfare and ethical issues for newly...

  2. Effect of water temperature on aggressiveness and physiological parameters of juvenile matrinxã, Brycon amazonicus (Spix and Agassiz, 1829)

    Contributor(s):: Ferreira, Juliana do N., de Barros, Igor B. A., Carvalho, Thaís B.

    The matrinxã (Brycon amazonicus) is one of the species with the greatest rates of commercialization in the Amazon region, however, it has a high frequency of aggressiveness and cannibalism, and these traits are considered a major obstacle to the aquaculture sector. Environmental factors (e.g.,...

  3. Stress coping styles: Is the basal level of stress physiological indicators linked to behaviour of sea bream?

    Contributor(s):: Alfonso, Sebastien, Zupa, Walter, Manfrin, Amedeo, Fiocchi, Eleonora, Spedicato, Maria Teresa, Lembo, Giuseppe, Carbonara, Pierluigi

    Stress coping style (SCS) is defined as a coherent set of individual physiological and behavioural differences in stress responses that are consistent across context and over time. SCS in fish has been studied, including because it has direct implications for aquaculture productivity and welfare....

  4. Using acoustic telemetry to assess behavioral responses to acute hypoxia and ammonia exposure in farmed rainbow trout of different competitive ability

    Contributor(s):: Gesto, Manuel, Zupa, Walter, Alfonso, Sébastien, Spedicato, Maria Teresa, Lembo, Giuseppe, Carbonara, Pierluigi

    As other vertebrates, fish differ on an individual basis in their responses to disturbance (i.e. stress) and in their capacity for adaptation to environmental change. This individual stress-coping style (SCS) might have an impact on the individual welfare in aquaculture facilities. However, most...

  5. Utilising spatial distribution in two-tank systems to investigate the level of aversiveness to crowding in farmed rainbow trout Oncorhynchus mykiss

    Contributor(s):: Laursen, Danielle Caroline, Andersson, Madelene Åberg, Silva, Patricia Isabel Mota, Petersson, Erik, Höglund, Erik

    In aquaculture, fish are exposed to a range of unfavourable environmental conditions. Amongst these, stocking density has attracted considerable attention as inappropriate densities may compromise welfare and negatively impact production. However, the recommendations for stocking remain elusive....

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

    Contributor(s):: de Souza, Ellen Cristina M., da Silva, Jaquelinne P., Villacorta-Correa, Marle Angélica, Carvalho, Thaís 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 matrinxã, Brycon amazonicus, is analyzed and compared. Each group of three larvae was observed at six...

  7. Reducing the incidence of net cage biting and the expression of escape-related behaviors in Atlantic cod (Gadus morhua) with feeding and cage enrichment

    Contributor(s):: Zimmermann, Emily W., Purchase, Craig F., Fleming, Ian A.

    The escape of fish from aquaculture is a persistent economic problem for farmers as well as an environmental problem that threatens wild fish population as a consequence of potential negative ecological and genetic interactions. Farmed Atlantic cod (Gadus morhua) cause significant damage by...

  8. Behavioural responses to hypoxia provide a non-invasive method for distinguishing between stress coping styles in fish

    Contributor(s):: Laursen, Danielle Caroline, L. Olsén, Hanna, Ruiz-Gomez, Maria de Lourdes, Winberg, Svante, Höglund, Erik

    Two divergent behavioural and physiological response patterns to challenges have been identified in mammals and birds, frequently termed the proactive and reactive coping styles. In recent years, individually distinct coping styles have also been observed in several species of fish. These...

  9. Stress response of farmed European abalone reveals rapid domestication process in absence of intentional selection

    Contributor(s):: Lachambre, Sébastien, Day, Rob, Boudry, Pierre, Huchette, Sylvain, Rio-Cabello, Antoine, Fustec, Timothée, Roussel, Sabine

    Farming, and thus the domestication of Haliotis tuberculata, began recently. We compared the responses of unselected farmed and wild abalone to stressors that occur on farms. The aim was to determine if the farm environment had induced differences in the behavioural or physiological performances...

  10. 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...

  11. 'A place for everything': moral landscapes of 'swiftlet farming' in George Town, Malaysia

    Contributor(s):: Connolly, C.

    This paper is based on 6 months of ethnographic, multi-sited research in Malaysia, and investigates the relatively recent phenomenon of edible birds' nest farming in urban areas ('swiftlet farming'). Swiftlet farms are typically converted shophouses or other buildings which have been modified for...

  12. In the water with white sharks (Carcharodon carcharias): participants' beliefs toward cage-diving in Australia

    Contributor(s):: Apps, K., Dimmock, K., Lloyd, D., Huveneers, C.

    White shark (Carcharodon carcharias) cage-diving tourism is a controversial activity that provokes emotional and often opposing points of view. With increasing demand for shark tourism since the 1990s, the underlying determinants driving this growth in participation remain unclear. This paper...

    How smart are fish? Integrating what scientists and fishers know

    The talks in this event will challenge the commonly-held view of fish as robot-like animals with no intelligence and a 30 second memory, which often leads to fish conservation being ignored in...

  14. Dusky dolphin (Lagenorhynchus obscurus) behavior and human interactions: implications for tourism and aquaculture

    Contributor(s):: Nicholas Matthew Thomson Duprey

    Interactions between humans and dusky dolphins in the coastal waters of New Zealand are increasing. My research focused on tourism interactions, with Kaikoura as the study site; and, on habitat use in an active aquaculture area, with Admiralty Bay as the study site. In Kaikoura, companies engaged...
