Digestive activities in developing Atlantic bluefin tuna (Thunnus thynnus)

Trabajo presentado en el Aquaculture Europe 16 (Food for Thought), celebrado en Edimburgo del 20 al 23 de septiembre de 2016.
The Atlantic bluefin Tuna (Thunnus thynnus) is one of the most commercially valuable marine fish species. Therefore, considerable research effort is being done since many years to advance in the farming techniques of this species. A good knowledge of the main events occurring at ontogenetic level is essential to advance in the design of more appropriate feeds and feeding protocols during the larval stage. In a first study we examined the organogenesis and development in general at histological level (Yúfera et al., 2014). In this study we have examined the activity of some digestive enzymes during the first weeks of life. With this aim the tuna larvae have been reared under mesocosm system with copepods as primary food source.
This research was financed by Project WEANTUNA (Eurostar E!7994) with FEDER/ERDF contribution.
