  1. Dietary fatty acid composition significantly influenced the proactive-reactive behaviour of Senegalese sole ( Solea senegalensis) post-larvae

    Contributor(s):: Ibarra-Zatarain, Z., Morais, S., Bonacic, K., Campoverde, C., Duncan, N.

    Few studies have examined the influence of diet on larval proactive-reactive behavioural dimension of stress coping style responses. The present study evaluated the influence of using different vegetables oils (Linseed; Soybean; Olive) and fish oil (Cod liver) for Artemia metanauplii nutritional...

  2. Evidence for pain in decapod crustaceans

    Contributor(s):: Elwood, R. W.

  3. 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,...

  4. Altered aggression in different sized groups of crayfish supports a dynamic social behaviour model

    Contributor(s):: Patullo, B. W., Baird, H. P., Macmillan, D. L.

    Living in groups with conspecifics can increase an animal's fitness in the wild. A social environment may also be imposed by commercial farming industries. One important measure of competition and group dynamics is the level of aggressive interaction. This can also influence the level of damage...

  5. Behaviour of juvenile mud crabs Scylla serrata in aquaculture: response to odours of moulting or injured crabs

    | Contributor(s):: Wall, D., Paterson, B., Mohan, R.

    Behaviour of juvenile mud crabs, Scylla serrata (70–90 mm carapace width, CW) were observed in response to odours of moulting and injured conspecifics and food (pilchard) under controlled flow conditions using bioassay technique. This study was undertaken to better...

  6. Cannibalism in juvenile blue-swimmer crabs Portunus pelagicus (Linnaeus, 1766): effects of body size, moult stage and refuge availability

    | Contributor(s):: Marshall, S., Warburton, K., Paterson, B., Mann, D.

    Factors influencing the rate of cannibalism in juvenile blue-swimmer crabs Portunus pelagicus were investigated under controlled conditions using time-lapse video recordings. This study was undertaken to improve blue-swimmer crab culture and experimentally addressed (1) prey vulnerability (2)...

  7. Claw removal and feeding ability in the edible crab, Cancer pagurus : implications for fishery practice

    | Contributor(s):: Patterson, L., Dick, J. T. A., Elwood, R. W.

    Feeding ability and motivation were assessed in the edible crab, Cancer pagurus, to investigate how the fishery practice of de-clawing may affect live crabs returned to the sea. Crabs were either induced to autotomise one claw, or were only handled, before they were offered food. Initially,...

  8. Motivational trade-offs and potential pain experience in hermit crabs

    | Contributor(s):: Appel, M., Elwood, R. W.

    One criterion of pain experience is that the emotional response to pain may be traded-off against other motivational requirements. This was tested in hermit crabs, housed in either preferred or unpreferred species of shells, by subjecting their abdomens to electric shocks of gradually increasing...

  9. Pain and stress in crustaceans? (Special Issue: Animal suffering and welfare.)

    | Contributor(s):: Elwood, R. W., Barr, S., Patterson, L.

    We consider evidence that crustaceans might experience pain and stress in ways that are analogous to those of vertebrates. Various criteria are applied that might indicate a potential for pain experience: (1) a suitable central nervous system and receptors, (2) avoidance learning, (3) protective...

  10. Effects of habitat complexity on the aggressive behaviour of the American lobster ( Homarus americanus ) in captivity

    | Contributor(s):: Cenni, F., Parisi, G., Gherardi, F.

    The American lobster, Homarus americanus, is one of the most economically valuable crustacean decapods worldwide, being mostly exploited to foster the live animal industry. Lobsters are typically held in storage facilities where individuals may suffer due to the repeated combats among each other....

  11. Charismatic krill? Size and conservation in the ocean

    | Contributor(s):: Leane, E., Nicol, S.

    The open ocean is an alien place for human beings and for most of history it has been studied using very indirect means. A great deal of what we know about animals that live on land, from ants to elephants, is based on centuries of direct natural history observations of animals alive and in situ....

  12. 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...
