PROGENSA Meeting, El Toruño-IFAPA2018-10-06
Researchers of the Institute of Aquaculture Torre la Sal (through Nutrigenomics and Fish Pathology Groups) have participated in the second meeting of the PROGENSAIII project (JACUMAR program) coordinated by ULPGC
The meeting, hosted by IFAPA-El Toruño, was organized by REMA-APROMAR for the knowledge transfer to the aquaculture sector (fish farmers and breeders) of main progress in sea bream genetics
CSIC has been focused on the effects of nutrition and genome interactions on fish performance and diseases progression in fish challenged with a myxozoan parasite (E. leei)
MAIN RESULT ACHIEVEMENTS
- Low fish meal and fish oil diets (< 10%) do not limit growth of fish with a different genetic background
- The intestine of fish selected for fast growth have a higher potential for an efficient digestion and absorption of nutrients
- The intestine is confirmed as a main target tissue for selective fish breeding in a scenario of reduced availability of marine feed ingredients
- Selection for fast growth is often related to a lower anaerobic capacity in challenged fish
- Selection for fast growth does not compromise fish health in a model of parasite enteritis
