  1. Stunning and killing of edible crabs ( Cancer pagurus )

    Contributor(s):: Roth, B., Oines, S.

    The stunning and killing efficiency of ice, superchilling (N2 gas), freezing (-37 degrees C), gradual heating (40 degrees C), boiling, piercing of ganglia, salt baths (NaCl and KCl), gas (CO2) and electricity (50 Hz AC) on edible crabs was studied. Results showed that electricity was the most...

  2. The effect of substrate availability on behavioural and physiological indicators of welfare in the African cichlid ( Oreochromis mossambicus )

    Contributor(s):: Galhardo, L., Correia, J., Oliveira, R. F.

    Male African cichlids (Oreochromis mossambicus) establish territories on the substrate upon which spawning pits are dug, thus attracting females. The substrate, therefore, plays a very significant role in its lifecycle. The effects of substrate access on behaviour and physiology in captivity were...

  3. The effects of education programmes on Atlantic bottlenose dolphin ( Tursiops truncatus ) behaviour

    Contributor(s):: Miller, L. J., Mellen, J., Greer, T., Kuczaj, S. A., II

    Atlantic bottlenose dolphins (Tursiops truncatus) are found in zoos and aquaria throughout the world. As the number of facilities with dolphin shows and interaction programmes increases, it becomes more important to understand the effects of such programmes on dolphin behaviour. The present study...

  4. The external locations of harpoon wounds on minke whales taken in antarctic commercial whaling operations, 1978/79 season

  5. The response of marine tucuxis ( Sotalia fluviatilis ) towards tourist boats involves avoidance behaviour and a reduction in foraging

    Contributor(s):: Carrera, M. L., Favaro, E. G. P., Souto, A.

    Marine ecotourism has undergone worldwide expansion in recent years, leading to increased concern regarding the impact on the environment. Despite this, however, few studies into the potential effect of tourist boats on dolphin welfare, have been carried out. In order to evaluate the impact of...
