1.Suresh et al. (2011):in feeds formulated with 20% poultry meal and no fishmeal, 3% of krill meal significantly improves feed attractab ility, palatab ility and shrimp growth
2.Sá et al. (2013): in a S t C -b ased feed with only 5.0% fish meal, a combination of whole squid meal and krill meal starting at 0.5% enhances shrimp final weight. Dreater effect at 2.0% of the diet.
3.H assan et al. (2016): a 1% dietary inclusion of krill meal in all-plant protein diets increases feed intake, while at 2% accelerates growth, increases yield and reduces CC w
4.Derb y et al. (2016): krill meal increases the feed palatab ility b y prolonging the feeding b out and the amount of feed eaten
