Coastal lagoons are marine ecosystems spread worldwide with high ecological value; however, they are increasingly becoming deteriorated as a result of anthropogenic activity. Their conservation requires a better understanding of the biodiversity factors that may help identifying priority areas. Riera, R., V. Tuset, R. Betancur-R, A. Lombarte, C. Marcos & A.

European Directive 2010/63 addresses the welfare of cephalopod species used in scientific projects under European jurisdiction and covers experimental procedures likely to cause pain, suffering, distress, or lasting harm. These procedures require authorization from the National Competent Authorities. In aquaculture research, some procedures require the temporary immobilization of individuals to allow for measuring body parameters (i.e., weight, sex, gonad condition, and others),avoiding any damage. This study compares three anesthetics used on common octopus, Octopus vulgaris,paralarvae to reach a state of sedation. Check it out here! Escánez, A., J. Rubio, R. Riera & E. Almansa. 2017.
