out of 5 stars

The ornamental pet trade is often considered a key culprit for conservation problems such as the introduction of invasive species (including infectious diseases) and overharvesting of rare species. Here, we present the first assessment of the biodiversity of freshwater molluscs in the...
Des exploitations intensives d'huitres pendant l'Antiquite et le Moyen Age sur le littoral atlantique francais: l'exemple de Beauvoir-sur-Mer (Vendee)
| Contributor(s):: Dupont, C., Rouzeau, N.
Along the European Atlantic facade, the consumption of flat oysters (Ostrea edulis Linnaeus, 1758) has been known since the Mesolithic era (Gutierrez-Zugasti et al. 2011). This observation is also true for French coasts (Dupont 2006). Especially during Antiquity, the exploitation of this species...

Using self-selection to evaluate the acceptance of a new diet formulation by farmed fish
| Contributor(s):: Carlberg, H., Cheng, Ken, Lundh, T., Brannas, E.
The evaluation of new diet composition is commonly achieved by performing time-consuming growth trials, which may negatively impact the welfare of a large number of fish if the feed is not accepted. Instead, the fish's behavioural responses to a new diet composition can be used as a first step in...
Consistent individual differences in the behavioural responsiveness of adult male cuttlefish ( Sepia officinalis)
| Contributor(s):: Carere, C., Grignani, G., Bonanni, R., Gala, M. della, Carlini, A., Angeletti, D., Cimmaruta, R., Nascetti, G., Mather, J. A.
Consistent individual differences in clusters of behaviour (animal personalities) are being increasingly recognized by researchers of different disciplines, but studies on invertebrates are still scanty. In order to test for the presence of personality-like individual profiles we assessed the...
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-...
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...
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...
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,...
