 The study found that the best performing extruded feed for growing European lobster, homerous gameras, juveniles was one containing 500 grams per kilogram of protein, 237 grams per kilogram of carbohydrates, and 119 grams per kilogram of lipids. This feed had the lowest feed conversion ratio, FCR, and the highest growth rate compared to other extruded feeds tested. Additionally, it showed the highest activity of trypsin and amylase, suggesting that the feed was more efficiently absorbing nutrients. Furthermore, the highest lipase activity indicated that the feed was better able to metabolize and store lipids. These findings indicate that this particular extruded feed could be a viable alternative to Antarctic krill, currently used to raise European lobster juveniles.
