Ireland: Krill shown to boost bass performance

So concludes a new study, recently published in Aquaculture, undertaken by scientists from the Research Group in Aquaculture (GIA) IU-ECOAQUA (Spain) and Aker BioMarine. In the study, European sea bass (Dicentrarchus labrax) were fed a practical diet with either a 15 percent fishmeal content or the same diet substituted by 30 percent or 50 percent Antarctic krill meal for 12 weeks in triplicates. At the end of the feeding trial, growth performance, liver morphology, liver proximate composition, lipid classes and fatty acid profiles, as well as the expression of hepatic genes related with lipid metabolism, were evaluated. The study concludes that there are multiple benefits of replacement fishmeal with Antarctic krill meal in diets for marine fish. “A sustainable growth of the aquaculture industry implies the use of eco-friendly ingredients as alternative to the traditional marine protein and lipid sources,” said Silvia Torrecillas senior researcher at GIA. “Our results indicate ...
