Scientists investigate a novel feed ingredient that enhances shrimp performance Dr. Alberto J.P. Nunes, Labomar and Tonje E. Dominguez, Aker BioMarine

Maintaining a healthy and thriving shrimp population is essential for the success of any shrimp farm. Farmers seek solutions that pack a nutritional punch to keep their shrimp stocks growing and thriving. It has become the task of scientists to experiment with ingredients, finding the right combination to enhance shrimp growth, health and overall survival. One ingredient stands out from the others in this research, revealing positive results on the shrimp populations tested. This ingredient is Antarctic krill (Euphausia superba) oil.

Astaxanthin krill oil proves to be an effective supplement for shrimp Shrimp farmers today strive for rapid animal growth and resistance to stress. By seeking shorter production crops with higher annual yields even

under environmental challenges, researchers are testing new ways to mitigate the effects of high salinity conditions while still fostering growth. One such solution can be found in astaxanthin krill oil. Researchers from LABOMAR Instituto de CiĂŞncias do Mar, Brazil, have done several interesting studies on the effect of astaxanthin krill oil as a performance supplement to Pacific whiteleg shrimp. An unpublished study (personal communication) performed a nursery trial in which post-larval (PL) Pacific whiteleg shrimp were fed graded dietary levels (0%, 1%, 3% and 5%) of astaxanthin krill oil (AKO) in a standardized diet to PL in 1-m3 outdoor tanks for 51 days. After harvest, growth was measured and a stress test was carried out to evaluate shrimp resistance to a
