dc.description.abstractThe common octopus (Octopus vulgaris) has aroused great interest in recent years as a new species for aquaculture. The current research is focused on developing a formulated feed, although a proper diet management has also promoted rearing success of other commercial cultured species. It is documented that wild animals eat depending on prey availability and most experience fasting in nature. Hence, O. vulgaris subadults were subjected to two different feeding schemes, with a similar semi-moist diet, including either 2 (2FDb, control) or 3 (3FDb) non-consecutive days of fasting per week. Growth, feed efficiency (FE), digestibility and condition were assessed after 56 days of rearing. Both feeding schemes promoted similar growth and digestibility (P>0.05), 100% of survival and higher food-intake after fasting. Interestingly, feed efficiency (FE) was enhanced with the 3 fasting days scheme (58.6% vs. 48.3% for 2FDb scheme; P<0.05). Results might indicate that O. vulgaris has the ability to compensate fasting days through an increase in food intake on the subsequent day or a better use of its reserves. Moreover, a reduction on feeding days might promote a decrease in production costs at commercial scale.pt_PT
