WWW.WAS.ORG • WORLD AQUACULTURE • JUNE 2014 53 quest for new methods to avoid pain and suffering in cephalopods, one of the research lines is to optimize the anaesthesia and euthanasia methodology employed in common octopus by testing different anaesthetics, such as cold water, clove oil, MgCl2 or ethanol (Perales-Raya et al. 2010). Future Goals • Identification of factors affecting the spawning quality (mainly female conditions and water temperature) to reduce the high variability among spawns. • Improvement of knowledge on digestive physiology, absorption and nutrient metabolism to design suitable diets. • Better understanding of behavior and physiology of wild paralarvae to better adapt the culture conditions and diet design. • Study the physiological mechanisms related to stress and select biomarkers to detect and quantify stress in paralarvae. • Perform beak analysis in paralarvae and identify the most stressful events across the paralarval stage to understand the causes of low survival of octopus paralarvae and the reasons for prevention of the settlement stage in captivity.
