Evaluación de dos anestésicos y metodología de marcaje individual con microchip subcutáneo en Octopus vulgaris

[EN]The present work evaluates, on one hand, two anaesthetic agents to facilitate octopus handling concluding that a 1.5% of ethanol (96%) in sea water (22ºC) shows rapid anaesthetic-recovery time, indicating its suitability for this species. On the other hand, a protocol for implanting Octopus vulgaris with subcutaneous PIT tags is established and after 10 weeks a 94% retention was found with 100% survival. Retention rises to 98,6% when tagging animals weighing more than 500 g.
