a CephsInAction Workshop
under the aegis of the COST Action FA1301
The digestive tract has not been the subject of extensive study, in contrast to many areas of cephalopod biology. Understanding its normal functioning has wide ranging implications for aquaculture, fisheries and for the care and welfare of cephalopods in the laboratory where research is now subject to regulation under Directive 2010/63/EU.
This one-day workshop is the occasion for an update on “the Digestive Tract of Cephalopods” through discussion on several important topics including physiology, nutritional requirements and diet in the wild, digestion and metabolism, welfare.
It is aimed to publish on scientific journal proceedings from the workshop. Further details are available here!!!
